copyMatchingFields(source, destination)

Copies all matching non empty columns (if overwrite boolean is given all columns except pk/ident, if array then all columns except pk and array names).
The matching requires the properties and getter functions of the source to match those of the destination; for the getter functions,
the 'get' will be removed and the remaining name will be converted to lowercase before attempting to match.
Returns true if no error occurred.

NOTE: This function could be used to store a copy of records in an archive table. Use the getRecord() function to get the record as an object.
Before trying this example, please make sure that the foundsets have some records loaded:

Parameters

Object source The source record or (java/javascript)object to be copied.
JSRecord destination The destination record to copy to.

getEditedRecords()

Returns an array of edited 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.

Returns

mergeRecords(sourceRecord, combinedDestinationRecord)

Merge records from the same foundset, updates entire datamodel (via foreign type on columns) with destination
record pk, deletes source record. Do use a transaction!

This function is very handy in situations where duplicate data exists. It allows you to merge the two records
and move all related records in one go. 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

JSRecord sourceRecord The source JSRecord to copy from.
JSRecord combinedDestinationRecord The target/destination JSRecord to copy into.

Returns

//Set autosave, if false then no saves will happen by the ui (not including deletes!). Until you call saveData or setAutoSave(true)
//reverts in mem the records that were edited and not yet saved. Best used in combination with autosave false.
databaseManager.setAutoSave(false)
//Now let users input data

//On save or cancel, when data has been entered:
if (cancel) databaseManager.revertEditedRecords()
//databaseManager.revertEditedRecords(foundset); // rollback all records from foundset
//databaseManager.revertEditedRecords(foundset.getSelectedRecord()); // rollback only one record
databaseManager.setAutoSave(true)

revertEditedRecords(foundset)

Reverts outstanding (not saved) in memory changes from edited records.

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 controll 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)

Supported Clients

SmartClient,WebClient,NGClient

}

rollbackTransaction(rollbackEdited)

Rollback a transaction started by databaseManager.startTransaction().
Note that when autosave is false, revertEditedRecords() will not handle deleted records, while rollbackTransaction() does.
Also, saved records within the transactions are restored to the database values, so user input is lost, to controll this see rollbackTransaction(boolean,boolean)

Parameters

Boolean rollbackEdited call rollbackEditedRecords() before rolling back the transaction

Supported Clients

SmartClient,WebClient,NGClient

Sample

// starts a database transaction
databaseManager.startTransaction()
//Now let users input data

//when data has been entered do a commit or rollback if the data entry is canceld or the the commit did fail.
if (cancel || !databaseManager.commitTransaction())
{
	databaseManager.rollbackTransaction();
}

rollbackTransaction(rollbackEdited, revertSavedRecords)

Rollback a transaction started by databaseManager.startTransaction().
Note that when autosave is false, revertEditedRecords() will not handle deleted records, while rollbackTransaction() does.

Parameters

Boolean rollbackEdited call rollbackEditedRecords() before rolling back the transaction
Boolean revertSavedRecords if false then all records in the transaction do keep the user input and are back in the edited records list. Note that if the pks of such a record are no longer used by it's foundset (find/search or load by query or ...) it will just be rolled-back as it can't be put in editing records list.

saveData()

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.

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 depeding 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 immediatelly 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.

Sample

databaseManager.saveData();
//databaseManager.saveData(foundset.getRecord(1));//save specific record
//databaseManager.saveData(foundset);//save all records from foundset

// when creating many records in a loop do a batch save on an interval as every 10 records (to save on memory and roundtrips)
// for (var recordIndex = 1; recordIndex <= 5000; recordIndex++)
// {
//		foundset.newRecord();
//		someColumn = recordIndex;
//		anotherColumn = "Index is: " + recordIndex;
//		if (recordIndex % 10 == 0) databaseManager.saveData();
// }

setAutoSave(autoSave)

Set autosave, if false then no saves will happen by the ui (not including deletes!).
Until you call databaseManager.saveData() or setAutoSave(true)

If you also want to be able to rollback deletes then you have to use databaseManager.startTransaction().
Because even if autosave is false deletes of records will be done.

Parameters

Boolean autoSave Boolean to enable or disable autosave.

Returns

Supported Clients

SmartClient,WebClient,NGClient

Sample

//Rollbacks in mem the records that were edited and not yet saved. Best used in combination with autosave false.
databaseManager.setAutoSave(false)
//Now let users input data

//On save or cancel, when data has been entered:
if (cancel) databaseManager.rollbackEditedRecords()
databaseManager.setAutoSave(true)

setCreateEmptyFormFoundsets()

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

Supported Clients

SmartClient,WebClient,NGClient

Sample

//this has to be called in the solution open method
databaseManager.setCreateEmptyFormFoundsets()

startTransaction()

Start a database transaction.
If you want to avoid round trips to the server or avoid the posibility of blocking other clients
because of your pending changes, you can use databaseManager.setAutoSave(false/true) and databaseManager.rollbackEditedRecords().

startTransaction, commit/rollbackTransacton() does support rollbacking of record deletes which autoSave = false doesnt support.

Supported Clients

SmartClient,WebClient,NGClient

Sample

// starts a database transaction
databaseManager.startTransaction()
//Now let users input data

//when data has been entered do a commit or rollback if the data entry is canceld or the the commit did fail.
if (cancel || !databaseManager.commitTransaction())
{
	databaseManager.rollbackTransaction();
}

switchServer(sourceName, destinationName)

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

String sourceName The name of the source database server connection
String destinationName The name of the destination database server connection.

Returns

Supported Clients

SmartClient,WebClient,NGClient

Sample

//dynamically changes a server for the entire solution, destination database server must contain the same tables/columns!
//will fail if there is a lock, transaction , if repository_server is used or if destination server is invalid
//in the solution keep using the sourceName every where to reference the server!
var success = databaseManager.switchServer('crm', 'crm1')
