Properties Details

alldataproviders

Get all dataproviders of the foundset.

Returns Array

Sample

var dataprovidersNames = alldataproviders;
application.output("This foundset has " + dataprovidersNames.length + " data providers.")
for (var i=0; i<dataprovidersNames.length; i++)
	application.output(dataprovidersNames[i]);

multiSelect

Get or set the multiSelect flag of the foundset.

Returns Boolean

Sample

// allow user to select multiple rows.
foundset.multiSelect = true;

Methods Details

addFoundSetFilterParam(query)

Add a filter parameter that is permanent per user session to limit a specified foundset of records.

Filters on tables touched in the query will not be applied to the query filter. For example, when a table filter exists on the order_details table, a query filter with a join from orders to order_details will be applied to the foundset, but the filter condition on the orders_details table will not be included.

Use clear(), reloadWithFilters(), loadRecords() or loadAllRecords() to make the filter effective. Multiple filters can be added to the same dataprovider, they will all be applied.

Parameters QBSelect query condition to filter on.

Returns Boolean true if adding the filter succeeded, false otherwise.

Sample

var query = datasources.db.example_data.orders.createSelect();
query.where.add(
   query.or.add(
            query.columns.shipcity.eq('Amersfoort'))
   .add(    query.columns.shipcity.eq('Amsterdam')));

var success = foundset.addFoundSetFilterParam(query, 'cityFilter'); // possible to add multiple
// Named filters can be removed using foundset.removeFoundSetFilterParam(filterName)

foundset.loadAllRecords(); // to make param(s) effective

addFoundSetFilterParam(query, name)

Add a filter parameter that is permanent per user session to limit a specified foundset of records.

Filters on tables touched in the query will not be applied to the query filter. For example, when a table filter exists on the order_details table, a query filter with a join from orders to order_details will be applied to the foundset, but the filter condition on the orders_details table will not be included.

Use clear(), reloadWithFilters(), loadRecords() or loadAllRecords() to make the filter effective. The filter is removed again using removeFoundSetFilterParam(name).

The table of the query has to be the same as the foundset table.

Parameters QBSelect query condition to filter on. Object name String name, used to remove the filter again.

Returns Boolean true if adding the filter succeeded, false otherwise.

Sample

var query = datasources.db.example_data.orders.createSelect();
query.where.add(
   query.or.add(
            query.columns.shipcity.eq('Amersfoort'))
   .add(    query.columns.shipcity.eq('Amsterdam')));

var success = foundset.addFoundSetFilterParam(query, 'cityFilter'); // possible to add multiple
// Named filters can be removed using foundset.removeFoundSetFilterParam(filterName)

foundset.loadAllRecords(); // to make param(s) effective

addFoundSetFilterParam(dataprovider, operator, value)

Parameters String dataprovider String column to filter on. String operator String operator: =, <, >, >=, <=, !=, (NOT) LIKE, (NOT) IN, (NOT) BETWEEN and IS (NOT) NULL optionally augmented with modifiers "#" (ignore case) or "^||" (or-is-null), prefix with "sql:" to allow the value to be interpreted as a custom query. Object value Object filter value (for in array and between an array with 2 elements)

Returns Boolean true if adding the filter succeeded, false otherwise.

Sample

var success = foundset.addFoundSetFilterParam('customerid', '=', 'BLONP', 'custFilter');//possible to add multiple
// Named filters can be removed using foundset.removeFoundSetFilterParam(filterName)

// you can use modifiers in the operator as well, filter on companies where companyname is null or equals-ignore-case 'servoy'
var ok = foundset.addFoundSetFilterParam('companyname', '#^||=', 'servoy')

// Filters with in-conditions can be used with arrays or with custom queries:
success = foundset.addFoundSetFilterParam("productcode", "in", [120, 144, 200]);
success = foundset.addFoundSetFilterParam("city", "in", ["London", "Paris"]);
// use "sql:in" in stead of "in" to allow the value to be interpreted as a custom query

clear()

Clear the foundset.

This will set a special condition in the query that makes the query not return any results.

But if new Records are added to this foundset, then those records become the query pk set. So it will then behave the same as loadRecord(pkset) of a pkset of those new records.

You can query for this state in the isCleared() call so you can call loadRecords() to remove that cleared state if needed.

//Clear the foundset, including searches that may be on it
foundset.clear();

foundset.duplicateRecord(3,true,true);

find()

Set the foundset in find mode. (Start a find request), use the "search" function to perform/exit the find.

Before going into find mode, all unsaved records will be saved in the database. If this fails (due to validation failures or sql errors) or is not allowed (autosave off), the foundset will not go into find mode. Make sure the operator and the data (value) are part of the string passed to dataprovider (included inside a pair of quotation marks). Note: always make sure to check the result of the find() method.

When in find mode, columns can be assigned string expressions (including operators) that are evaluated as: General: c1||c2 (condition1 or condition2) c|format (apply format on condition like 'x|dd-MM-yyyy') !c (not condition) #c (modify condition, depends on column type) ^ (is null) ^= (is null or empty) <x (less than value x) >x (greater than value x) <=x (less than or equals value x) >=x (greater than or equals value x) x...y (between values x and y, including values) x (equals value x)

Number fields: =x (equals value x) ^= (is null or zero)

Date fields: #c (equals value x, entire day) now (equals now, date and or time) // (equals today) today (equals today)

Text fields: #c (case insensitive condition) = x (equals a space and 'x') ^= (is null or empty) %x% (contains 'x') %x_y% (contains 'x' followed by any char and 'y') % (contains char '%') _ (contains char '_')

Related columns can be assigned, they will result in related searches. For example, "employees_to_department.location_id = headoffice" finds all employees in the specified location).

Searching on related aggregates is supported. For example, "orders_to_details.total_amount = '>1000'" finds all orders with total order details amount more than 1000.

Arrays can be used for searching a number of values, this will result in an 'IN' condition that will be used in the search. The values are not restricted to strings but can be any type that matches the column type. For example, "record.department_id = [1, 33, 99]"

Multiple Find Records for Logical OR: It's important to note that when in Find Mode, a foundset will initially contain one record object. However, multiple record objects may be used to articulate search criteria. This has the effect that the criteria described in each record are concatenated by a SQL OR.

Returns Boolean true if the foundset is now in find mode, false otherwise.

Sample

if (foundset.find()) //find will fail if autosave is disabled and there are unsaved records
{
	columnTextDataProvider = 'a search value'
	// for numbers you have to make sure to format it correctly so that the decimal point is in your locales notation (. or ,)
	columnNumberDataProvider = '>' + utils.numberFormat(anumber, '####.00');
	columnDateDataProvider = '31-12-2010|dd-MM-yyyy'
	foundset.search()
}

// Multiple Find Records for Logical OR - example
// Find customers in the city of Berlin AND in the postal code 12209...
// OR customers in the city of San Francisco AND in the postal code 94117
if (foundset.find()) // Enter find mode    city = 'Berlin';
{
	city = 'Berlin';   // Assign a search criteria
	postalcode = '12209';
	foundset.newRecord();   // Create a new search record
	city = 'San Francisco';
 postalcode = '94117';
	foundset.search();      // Execute the query and load the records
}

forEach(callback)

Iterates over the records of a foundset taking into account inserts and deletes that may happen at the same time. It will dynamically load all records in the foundset (using Servoy lazy loading mechanism). If callback function returns a non null value the traversal will be stopped and that value is returned. If no value is returned all records of the foundset will be traversed. Foundset modifications( like sort, omit...) cannot be performed in the callback function. If foundset is modified an exception will be thrown. This exception will also happen if a refresh happens because of a rollback call for records on this datasource when iterating. When an exception is thrown from the callback function, the iteration over the foundset will be stopped.

Parameters Function callback The callback function to be called for each loaded record in the foundset. Can receive three parameters: the record to be processed, the index of the record in the foundset, and the foundset that is traversed.

Returns Object Object the return value of the callback

Sample

foundset.forEach(function(record,recordIndex,foundset) {
 	//handle the record here
 });

forEach(callback, thisObject)

Iterates over the records of a foundset taking into account inserts and deletes that may happen at the same time. It will dynamically load all records in the foundset (using Servoy lazy loading mechanism). If callback function returns a non null value the traversal will be stopped and that value is returned. If no value is returned all records of the foundset will be traversed. Foundset modifications( like sort, omit...) cannot be performed in the callback function. If foundset is modified an exception will be thrown. This exception will also happen if a refresh happens because of a rollback call for records on this datasource when iterating. When an exception is thrown from the callback function, the iteration over the foundset will be stopped.

Parameters Function callback The callback function to be called for each loaded record in the foundset. Can receive three parameters: the record to be processed, the index of the record in the foundset, and the foundset that is traversed. Object thisObject What the this object should be in the callback function (default it is the foundset)

Returns Object Object the return value of the callback

Sample

foundset.forEach(function(record,recordIndex,foundset) {
 	//handle the record here
 });

getCurrentSort()

Get the current sort columns.

Returns String String sort columns

Sample

//the original sort "companyName asc, companyContact desc"
//the inversed sort "companyName desc, companyContact asc"
var foundsetSort = foundset.getCurrentSort()
var sortColumns = foundsetSort.split(',')
var newFoundsetSort = ''
for(var i=0; i<sortColumns.length; i++)
{
	var currentSort = sortColumns[i]
	var sortType = currentSort.substring(currentSort.length-3)
	if(sortType.equalsIgnoreCase('asc'))
	{
		newFoundsetSort += currentSort.replace(' asc', ' desc')
	}
	else
	{

getParentRecords()

Gets the parent records when called on a related foundset. (empty array if not a related foundset) Depending on the cardinality of the relation, this method returns either 1 or more records. This can be useful when creating a new record in an empty related foundset and some data from the parent record(s) is needed.

Be aware that if datasources.xxx.getFoundset() is called multiple times on the same datasource it creates multiple foundset instances then the related foundset can have multiple references to the same parent record but in different foundsets. (different instances of the record for the same row in the database) In that case, this method will return the record from the first foundset.

Returns Array an array of records

Sample

var parents = relatedFoundset.getParentRecords();

getQuery()

Note that foundset filters are optionally included and table filters are not included in the query.

Returns QBSelect query.

Sample

var q = foundset.getQuery()
q.where.add(q.columns.x.eq(100))
foundset.loadRecords(q);

getQuery(includeFilters)

Get the query that the foundset is currently using (as a clone; modifying this QBSelect will not automatically change the foundset). When the foundset is in find mode, the find conditions are included in the resulting query. So the query that would be used when just calling search() (or search(true,true)) is returned. Note that foundset filters are optionally included and table filters are not included in the query.

loadAllRecords()

Loads all accessible records from the datasource into the foundset. Filters on the foundset are applied.

Before loading the records, all unsaved records will be saved in the database. If this fails (due to validation failures or sql errors) or is not allowed (autosave off), records will not be loaded,

Returns Boolean true if records are loaded, false otherwise.

Sample

foundset.loadAllRecords();

loadOmittedRecords()

Loads the records that are currently omitted as a foundset.

Before loading the omitted records, all unsaved records will be saved in the database. If this fails (due to validation failures or sql errors) or is not allowed (autosave off), omitted records will not be loaded,

Returns Boolean true if records are loaded, false otherwise.

Sample

foundset.loadOmittedRecords();

loadRecords()

Reloads all last (related) records again, if, for example, after search in tabpanel. When in find mode, this will reload the records from before the find() call.

Returns Boolean true if successful

Sample

//to reload all last (related) records again, if for example when searched in tabpanel
 foundset.loadRecords();

loadRecords(foundset)

Copies foundset data from another foundset. This will alter the foundset state to the state of the foundset that is given. If you really just want to use the given foundset on the form itself, then you need to use controller.loadRecords(foundset) that will change the instance of the foundset that is used for this form. Not just update an existing forms foundset.

If you copy over a relation into this foundset, then this foundset will not be a related foundset, it will not automatically update its state of records are updated or added that belong to that relation. It will only be a snapshot of that related foundsets state.

Foundset filter params are copied over from the original/source foundset and are merged with the existing filters on this foundset. So if the original foundset had filters and the given foundset has filters then the resulting foundset will have all the filters of both, If you don't want this and you really want only the state of the given foundset, use controller.loadRecords(fs) instead of foundset.loadRecords(fs)

Parameters JSFoundSet foundset The foundset to load records from

Returns Boolean true if successful

Sample

//Copies foundset data from another foundset
foundset.loadRecords(fs);

loadRecords(dataset)

Loads a primary key dataset, will remove related sort. Tries to preserve selection based on primary key, otherwise first record is selected.

Parameters JSDataSet dataset pkdataset

Returns Boolean true if successful

Sample

// loads a primary key dataset, will remove related sort!
//var dataset = databaseManager.getDataSetByQuery(...);
// dataset must match the table primary key columns (alphabetically ordered)
foundset.loadRecords(dataset);

loadRecords(querybuilder)

Loads records into form foundset based on a query builder object (also known as 'Form by query'). When the foundset is in find mode, the find states are discarded, the foundset will go out of find mode and the foundset will be loaded using the query. If the foundset is related, the relation-condition will be added to the query. Tries to preserve selection based on primary key, otherwise first record is selected.

The query of the QBSelect that is given is added as a "search" condition to the existing base query of the foundset. This does mean that loadAllRecords() will revert this, because that will clear the search condition and go back to the base query of the foundset. Some hold true for clear() that will remove the search condition and because of that the given query will also be removed.

If you want to create more a "view" on your database that will always be kept by this foundset, so loadAllRecords() (with our withou first calliing clear()) will always revert back to this set of data (and you can also search inside this data with find/search or adding another query on top of it. Then have a look at datasources.db.server.table.getFoundset(query) because that will generate a foundset with the given query as the base query.

Parameters QBSelect querybuilder the query builder

Returns Boolean true if successful

Sample

var qb = datasources.db.example_data.orders.createSelect();
qb.result.addPk();
qb.where.add(qb.columns.product_id.eq(1))
foundset.loadRecords(qb);

loadRecords(uuidpk)

Loads a single record by primary key, will remove related sort.

NOTE: This function will return true if the foundset was altered/changed. It is up to the developer to check for the presence of actual data using getSize().

Parameters UUID uuidpk single-column pk value

Returns Boolean true if successful

Sample

//Loads a single record by primary key, will remove related sort!
foundset.loadRecords(application.getUUID('6b5e2f5d-047e-45b3-80ee-3a32267b1f20'));

loadRecords(numberpk)

Loads a single record by primary key, will remove related sort.

NOTE: This function will return true if the foundset was altered/changed. It is up to the developer to check for the presence of actual data using getSize().

Parameters Number numberpk single-column pk value

Returns Boolean true if successful

Sample

//Loads a single record by primary key, will remove related sort!
foundset.loadRecords(123);

loadRecords(queryString)

Loads records into form foundset based on a query (also known as 'Form by query'). The query must be a valid sql select. If the foundset is related this function is not allowed. Tries to preserve selection based on primary key, otherwise first record is selected.

see foundset.loadRecords(QBSelect).

When possible, the foundset will be loaded with the given query. This is not always possible because the foundset needs to manipulate the query when adding conditions and joins. In that case the query will be wrapped: select pk from tab where pk = (queryString) The result is the same, except for the ordering in the queryString which will be ignored.

The query will be wrapped when one of the following is true:

• you have no order-by clause

• you have no from keyword

• your query is not fully qualified on the main table

• you have a group-by, having, join or union keyword

Parameters String queryString select statement

Returns Boolean true if successful

Sample

//loads records in to the foundset based on a query (also known as 'Form by query')
foundset.loadRecords(sqlstring);

loadRecords(queryString, argumentsArray)

Parameters String sortString the specified columns (and sort order)

Returns void

Sample

foundset.sort('columnA desc,columnB asc');

sort(sortString, defer)

Sorts the foundset based on the given sort string. Tries to preserve selection based on primary key. If first record is selected or cannot select old record it will select first record after sort. TIP: You can use the Copy button in the developer Select Sorting Fields dialog to get the needed syntax string for the desired sort fields/order.

Parameters String sortString the specified columns (and sort order) Boolean defer when true, the "sortString" will be just stored, without performing a query on the database (the actual sorting will be deferred until the next data loading action).

Returns void

Sample
