Description
Sets the parameters for a specified SQL statement type, and executes the resulting statement.
Call Apply to set parameters for an SQL statement and execute it to update a record. UpdateKind indicates which SQL statement to bind and execute, and can be one of the following values:
| Value | Meaning |
|---|---|
|
ukDelete |
Bind and execute the SQL statement in the DeleteSQL property |
|
ukInsert |
Bind and execute the SQL statement in the InsertSQL property |
|
ukModify |
Bind and execute the SQL statement in the ModifySQL property |
Apply is primarily intended for manually executing update statements from an OnUpdateRecord event handler.
Note: If an SQL statement does not contain parameters, it is more efficient to call ExecSQL instead of Apply.
