TableDeleteSelect (Function)

In french: TableSupprimeSelect

Deletes the selected rows from a Table or Treeview Table control.

Example

// Supprime toutes les lignes sélectionnées
IF YesNo("Voulez-vous vraiment supprimer les clients sélectionnés ?") THEN
	TableDeleteSelect(TABLE_Affichage_Client)
END

Syntax

TableDeleteSelect(<Table control>)

<Table control>: Control name

Name of the control to be used. This control can correspond to:
a Table control.
a TreeView Table control.

Remarks

Use conditions

TableDeleteSelect can be used on:

Table or TreeView Table controls based on a data file.
Table or TreeView Table controls populated programmatically.
single-selection or multi-selection controls.
Reminder Multi-selection is not available for Table control fields in classic mode.

This function is available for Table control fields in AJAX mode, Table control fields in classic mode and TreeView Table control fields.

This function is only available for Browser Table controls.. The TreeView Table control is not available.

Deleting records in a Table or TreeView Table control based on a data file

TableDeleteSelect deletes the corresponding records from the data file associated with the control. If items are linked to other data files, no modification is automatically performed on these linked data files.

Referential integrity and Table or TreeView Table controls based on a data file

If the management of referential integrity is enabled (HSetIntegrity), HErrorIntegrity must be called after TableDeleteSelect to check the integrity. If an integrity error is detected, the row is not deleted and it remains visible in the control.

Deleting records in a Table control based on a data file and Trigger

You have the ability to activate a trigger when deleting a record from a Table control based on a data file. For more details, see the documentation about HDescribeTrigger.

Handling errors

The ErrorOccurred variable is set to True if the deletion fails. To get the details of the error, use ErrorInfo.

Locking the linked data file

If the data file is locked in the current process, TableDeleteSelect deletes the specified row and unlocks the data file.
