(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 Boolean - true if the records could me merged. |

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 {Object} foundsetOrRecord - JSFoundset or JSRecord to recalculate. |
|
|
Sample // recalculate one record from a foundset.
databaseManager.recalculate(foundset.getRecord(1));

|
|
Parameters {Object} foundset - The JSFoundset to refresh {Number} index - The index of the JSRecord that must be refreshed (or -1 for all). |
|
|
Returns Boolean - true if the refresh was done. |

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() This does not include deletes, they do not honor the autosafe false flag so they cant be rollbacked by this call. |
|
|
Sample //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) |

//databaseManager.revertEditedRecords(foundset.getSelectedRecord()); // rollback only one record
databaseManager.setAutoSave(true) |
|
|
|
|
Rollback a transaction started by databaseManager.startTransaction(). Note that when autosave is false, rollbackEditedRecords() 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 controll this see rollbackTransaction(boolean,boolean) |
|
|
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();
} |
|
|
|
|
Rollback a transaction started by databaseManager.startTransaction(). Note that when autosave is false, rollbackEditedRecords() 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 |
|
|
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();
} |
|
|
|
|
(rollbackEdited, revertSavedRecords) |
|
|
Rollback a transaction started by databaseManager.startTransaction(). Note that when autosave is false, rollbackEditedRecords() 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 |
|
|
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();
} |

|
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. |
|
|
Returns Boolean - true if the save was done without an error. |
|
|
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();

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 Boolean - false if the current edited record could not be saved. |
|
|
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 |
|
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 |
|
|
Sample //this has to be called in the solution open method
databaseManager.setCreateEmptyFormFoundsets() |
|
|
|
|
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. |
|
|
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();
} |
|
|
|
|
(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 Boolean - true if the switch could be done. |
|
|
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') |
