next |
Boolean next () |
Go to next record in this updater, returns true if successful.
|
Returns Boolean – true if proceeded to next record, false otherwise
|
Samplecontroller.setSelectedIndex(1) var count = 0 var fsUpdater = databaseManager.getFoundSetUpdater(foundset) while(fsUpdater.next()) { fsUpdater.setColumn('my_flag',count++) } |
performUpdate |
Boolean performUpdate () |
Do the actual update in the database, returns true if successful.
There are 3 types of possible use with the foundset updater 1) update entire foundset by a single sql statement; that is not possible when the table of the foundset has tracking enabled then it will loop over the whole foundset. When a single sql statement is done, modification columns will not be updated, because it does the update directly in the database, without getting the records. 2) update part of foundset, for example the first 4 row (starts with selected row) 3) safely loop through foundset (starts with selected row) |
Returns Boolean – true if succeeded, false if failed.
|
Sample//1) update entire foundset var fsUpdater = databaseManager.getFoundSetUpdater(foundset) fsUpdater.setColumn('customer_type',1) fsUpdater.setColumn('my_flag',0) fsUpdater.performUpdate() //2) update part of foundset, for example the first 4 row (starts with selected row) var fsUpdater = databaseManager.getFoundSetUpdater(foundset) fsUpdater.setColumn('customer_type',new Array(1,2,3,4)) fsUpdater.setColumn('my_flag',new Array(1,0,1,0)) fsUpdater.performUpdate() //3) safely loop through foundset (starts with selected row) controller.setSelectedIndex(1) var count = 0 var fsUpdater = databaseManager.getFoundSetUpdater(foundset) while(fsUpdater.next()) { fsUpdater.setColumn('my_flag',count++) } |
resetIterator |
void resetIterator () |
Start over with this iterator 'next' function (at the foundset selected record).
|
Returns void
|
Samplecontroller.setSelectedIndex(1) var count = 0 var fsUpdater = databaseManager.getFoundSetUpdater(foundset) while(fsUpdater.next()) { fsUpdater.setColumn('my_flag',++count) } fsUpdater.resetIterator() while(fsUpdater.next()) { fsUpdater.setColumn('max_flag',count) } |
setColumn |
Boolean setColumn (name, value) |
Set the column value to update, returns true if successful.
|
Parameters |
Returns Boolean – true if succeeded, false if failed.
|
Sample//1) update entire foundset var fsUpdater = databaseManager.getFoundSetUpdater(foundset) fsUpdater.setColumn('customer_type',1) fsUpdater.setColumn('my_flag',0) fsUpdater.performUpdate() //2) update part of foundset, for example the first 4 row (starts with selected row) var fsUpdater = databaseManager.getFoundSetUpdater(foundset) fsUpdater.setColumn('customer_type',new Array(1,2,3,4)) fsUpdater.setColumn('my_flag',new Array(1,0,1,0)) fsUpdater.performUpdate() //3) safely loop through foundset (starts with selected row) controller.setSelectedIndex(1) var count = 0 var fsUpdater = databaseManager.getFoundSetUpdater(foundset) while(fsUpdater.next()) { fsUpdater.setColumn('my_flag',count++) } |
