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

IF YesNo("Do you really want to delete the selected customers?") THEN

END
Syntax
TableDeleteSelect(<Table control>)
<Table control>: Control name
Name of control to use. This control can correspond to:
  • a Table control.
  • a TreeView Table control.
Remarks

Use conditions

TableDeleteSelect can be used on:
  • a browsing or memory control.
  • a single-selection or multiselection control.

Deletion in a browsing Table or TreeView Table control

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 browsing Table or TreeView Table control

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.

Deletion in a browsing Table control and Trigger

You have the ability to activate a trigger when deleting a record from a browsing Table control. See the documentation about HDescribeTrigger for more details.

Managing the errors

The ErrorOccurred variable is set to True if the deletion fails. To find out the error details, 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.
