(databaseManager)
The Database Manager offers extensive tools for managing datasources, queries, records, and transactions, enabling the creation of efficient and scalable data-driven applications. It supports interaction with both in-memory and database-bound datasources, advanced query construction, and record management.
The system allows dynamic creation of datasources using createDataSourceByQuery, which populates datasources with query results while enabling reuse if the data structure remains consistent. Developers can specify or infer column types and remove unused datasources using removeDataSource to optimize resource usage. Query handling is further enhanced with the QBSelect object, enabling the programmatic construction of complex queries. The manager also supports ViewFoundSets, which create filtered, read-only views of database tables suitable for custom data presentation and aggregation.
Record management is facilitated by functions like saveData for committing changes, validate for enforcing data constraints, and mergeRecords for resolving duplicate records by merging their associated data. Unsaved changes can be reverted with revertEditedRecords, and the system tracks edited, new, or unsaved records using functions like getEditedRecords. Developers can ensure data integrity by starting transactions with startTransaction and rolling back changes using rollbackTransaction if necessary.
Table filters enable the restriction of data access through both column-based and query-based conditions. Filters can be dynamically applied, updated, or removed using setTableFilters and removeTableFilterParam. The manager provides utilities like getTable to retrieve schema details, getTableCount to determine record counts, and getTableFilterParams to inspect active filters.
Lock management is supported through hasLocks to check acquired locks and releaseAllLocks to release them, ensuring safe multi-user interactions. To reflect external data changes, cached records can be refreshed using refreshRecordFromDatabase.
Validation tools ensure that records conform to constraints such as column lengths and non-null requirements through the validate function. Performance optimization is achieved with recalculate to refresh derived values and flushCalculations to clear unnecessary data in memory, reducing resource overhead.
These capabilities provide developers with a comprehensive framework for building robust and customizable database-driven solutions.

Sample
Enable/disable the automatic prefetching of related foundsets for sibling records.
For example, when orders from a record in a customer foundset are retrieved, already the orders of a few sibling records are also prefetched. By default this prefetch is enabled for SmartClient but is disabled for all serverbased clients like NGClient and HeadlessClient. Because server based client are close enough to the database that they can fetch the siblings themselfs

Parameters
Sample
Returns an array of edited or deleted records with outstanding (unsaved) data.
This is different form JSRecord.isEditing() because this call actually checks if there are changes between the current record data and the stored data in the database. If there are no changes then the record is removed from the edited records list (so after this call JSRecord.isEditing() can return false when it returned true just before this call)
NOTE: To return a dataset of outstanding (unsaved) edited data for each record, see JSRecord.getChangedData(); NOTE2: The fields focus may be lost in user interface in order to determine the edits.

For query-based filters, a row of 2 fields per filter are returned. The "columns" of a row from this array are: query, filtername
Parameters
Sample
Returns an array of all table names for a specified server.
Parameters
Sample
Returns a ViewFoundSet that was created by getViewFoundSet(name,query,register) with the registerd boolean "true". So it is registered and remembered by the system to use in Forms. You can't get ViewFoundSet back that are not registered to the system, those are not remembered.
Parameters
Returns a foundset object for a specified query. This just creates one without keeping any reference to it, you have to use the getViewFoundSet(name,query,true) for registering it to the system. ViewFoundSets are different then normal foundsets because they have a lot less methods, stuff like newRecord/deleteRecord don't work.
If you query the pk with the columns that you display for the main or join tables then those columns can be updated and through ViewFoundSet#save(ViewRecord) they can be saved. If there are changes in ViewRecords of this ViewFoundSet then databroadcast configurations that need to load new data won't do the query right away (only after the save) Also loading more (the next chunksize) will not be done. This is because the ViewRecord on an index can be completely changed. We can't track those.
Also databroadcast can be enabled by calling one of the ViewFoundSet#enableDatabroadcastFor(QBTableClause) to listen for that specific table (main or joins). Flags can be used to control what exactly should be monitored, some don't cost a lot of overhead others have to do a full re-query to see the changes.
Parameters
Sample
Returns a foundset object for a specified query. If the boolean register is true then the system will register it to the system so it can be used in Forms. Also getViewFoundSet(name) will then return that instance. ViewFoundSets are different then normal foundsets because they have a lot less methods, stuff like newRecord/deleteRecord don't work.
If you query the pk with the columns that you display for the main or join tables then those columns can be updated and through ViewFoundSet#save(ViewRecord) they can be saved. If there are changes in ViewRecords of this ViewFoundSet then databroadcast configurations that need to load new data won't do the query right away (only after the save) Also loading more (the next chunksize) will not be done. This is because the ViewRecord on an index can be completely changed. We can't track those.

Flags can be used to control what exactly should be monitored, some don't cost a lot of overhead others have to do a full re-query to see the changes.
if the register boolean is true, then the given ViewFoundSet is registered to the system so it is picked up by forms that have this datasource (see viewFoundset.getDatasource() for the actual datasource string) assigned. The form's foundset will then have a much more limited API, so a lot of things can't be done with it - e.g. newRecord() or deleteRecords(). Also records can be updated in memory, so they are not fully read-only, but the developer is responsible for saving these changes to a persisted store. See also viewFoundset.save(...).
If the solution doesn't need this ViewFoundSet anymore and you did use register is true, please use ViewFoundSet.dispose() to clear and remove it from the system, because otherwise this register call will keep/hold this foundset in memory (for that datasource string to work) forever.

Say the source_record is "Ikea" and the combined_destination_record is "IKEA", the "Ikea" record is deleted and all records related to it (think of contacts and orders, for instance) will be related to the "IKEA" record.
The function takes an optional array of column names. If provided, the data in the named columns will be copied from source_record to combined_destination_record.
Note that it is essential for both records to originate from the same foundset, as shown in the sample code.

Parameters
Sample
Can be used to recalculate a specified record or all rows in the specified foundset. May be necessary when data is changed from outside of servoy, or when there is data changed inside servoy but records with calculations depending on that data where not loaded so not updated and you need to update the stored calculation values because you are depending on that with queries or aggregates.
Parameters
Returns: void
Sample
Flushes the client data cache and requeries the data for a record (based on the record index) in a foundset or all records in the foundset. Used where a program external to Servoy has modified the database record. Giving 0 as the index will just refresh he selected record.
If the index is -1 then this method will refresh all the records of the datasource of the foundset, it does this by flusing all the records and the row data of the full datasource So everything is reloaded fully fresh when the foundsets will requery for there data. WARNING: Don't hold any references to JSRecord objects from before this call with -1 index. Those records objects are all in an invalid state because of the underlying data flush.
Parameters
Sample
Release all current locks the client has (optionally limited to named locks). return true if the locks are released.
Sample
Release all current locks the client has (optionally limited to named locks). return true if the locks are released.
Parameters
Sample
Free resources allocated for a previously created data source. NOTE: make sure this datasource is not using anymore in forms or components! because the inmemory table and the foundset build on that table are all just removed.
Normally this will be automatically done if a client is removed/shutdown, but if constantly new stuff is created or you don't need it anymore from what the client currently is using or seeing, then removing this will clean up memory.
Parameters
Sample
Removes a previously defined table filter.
Parameters
Sample
Reverts outstanding (not saved) in memory changes from edited records. Can specify a record or foundset as parameter to rollback. Best used in combination with the function databaseManager.setAutoSave()
Returns: void
Sample
Reverts outstanding (not saved) in memory changes from edited records. Can specify a record or foundset as parameter to rollback. Best used in combination with the function databaseManager.setAutoSave()
Parameters
Returns: void
Sample
Rollback a transaction started by databaseManager.startTransaction(). Note that when autosave is false, revertEditedRecords() will not handle deleted records, while rollbackTransaction() does. Also, rollbackEditedRecords() is called before rolling back the transaction see rollbackTransaction(boolean) to control that behavior and saved records within the transactions are restored to the database values, so user input is lost, to control this see rollbackTransaction(boolean,boolean)
Returns: void

Parameters
Returns: void
Sample
Rollback a transaction started by databaseManager.startTransaction(). Note that when autosave is false, revertEditedRecords() will not handle deleted records, while rollbackTransaction() does.
Parameters
Returns: void
Sample
Saves all outstanding (unsaved) data and exits the current record. Optionally, by specifying a record or foundset, can save a single record or all records from foundset instead of all the data. You can call saveData for a record or foundset inside a Table Event (save all will not work), and that will only save the records that are currently not being saved (to avoid infinite cycles). Since Servoy 8.3 saveData with null parameter does not call saveData() as fallback, it just returns false.
NOTE: The fields focus may be lost in user interface in order to determine the edits. saveData() called from table events (like afterRecordInsert) is only partially supported depending on how first saveData() (that triggers the event) is called. If first saveData() is called with no arguments, all saveData() from table events are returning immediately with true value and records will be saved as part of first save. If first saveData() is called with record(s) as arguments, saveData() from table event will try to save record(s) from arguments that are different than those in first call. saveData() with no arguments inside table events will always return true without saving anything.
NOTE: When saveData() is called within a transaction, records after a record that fails with some sql-exception will not be saved, but moved to the failed records. record.exception.getErrorCode() will return ServoyException.MUST_ROLLBACK for these records.

Parameters
Sample
Set autosave, if false then no saves or deletes will happen by the ui. Until you call databaseManager.saveData() or setAutoSave(true) *
Parameters
Sample
Turnoff the initial form foundset record loading, set this in the solution open method. Simular to calling foundset.clear() in the form's onload event.
NOTE: When the foundset record loading is turned off, controller.find or controller.loadAllRecords must be called to display the records
Returns: void
Sample
Apply multiple table filters to all the foundsets that are affected by the filters. After all filters have been applied / updated, foundset changes will be applied in the client.
The filters that have been applied with the same filter name will be removed and replaced with the new set of filters (which may be empty).
Parameters
Sample
Start a database transaction. If you want to avoid round trips to the server or avoid the possibility of blocking other clients because of your pending changes, you can use databaseManager.setAutoSave(false/true) and databaseManager.rollbackEditedRecords().
Returns: void
Sample
Switches a named server to another named server with the same datamodel (recommended to be used in an onOpen method for a solution). return true if successful. Note that this only works if source and destination server are of the same database type.
Parameters
Sample
Validates the given record, it runs first the method that is attached to the entity event "onValidate". Then it will call also the entity events "onInsert" or "onUpdate" depending if the record is new or an update. All those methods do get a parameter JSRecordMarkers where the problems can be reported against.
All columns are then also null/empty checked and if they are and the Column is marked as "not null" an error will be added with the message key "servoy.record.error.null.not.allowed" for that column.
All changed columns are length checked and if the record values is bigger then what the database column can handle and error will be added with the message key "servoy.record.error.columnSizeTooSmall" for that column. Then all the column validators will be run over all the changed columns, The validators will also get the same JSRecordMarkers to report problems to. So the global method validator now also has more parameters then just the value.
These 3 validations (null, length and column validators) are not by default done any more on change of the dataprovider itself. This is controlled by the servoy property "servoy.execute.column.validators.only.on.validate_and_save" which can also be seen at the TableEditor column validators page.
An extra state object can be given that will also be passed around if you want to have more state in the validation objects (like giving some ui state so the entity methods know where you come from)
It will return a JSRecordMarkers when the record had validation problems
