Example 17 with IServer

use of com.servoy.j2db.persistence.IServer in project servoy-client by Servoy.

the class JSDatabaseManager method js_mergeRecords.

// strongly recommended to use a transaction
// currently does not support compound pks
/**
 * 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.
 *
 * @sample databaseManager.mergeRecords(foundset.getRecord(1),foundset.getRecord(2));
 *
 * @param sourceRecord The source JSRecord to copy from.
 * @param combinedDestinationRecord The target/destination JSRecord to copy into.
 * @param columnNames The column names array that should be copied.
 *
 * @return true if the records could me merged.
