ActionScheduler_LoggerSchema::update_schema_3_0() public WC 1.0

Update the logs table schema, allowing datetime fields to be NULL.

This is needed because the NOT NULL constraint causes a conflict with some versions of MySQL configured with sql_mode=NO_ZERO_DATE, which can for instance lead to tables not being created.

Most other schema updates happen via ActionScheduler_Abstract_Schema::update_table(), however that method relies on dbDelta() and this change is not possible when using that function.

{} It's a method of the class: ActionScheduler_LoggerSchema{}

No Hooks.

Return

null. Nothing.

Usage

$ActionScheduler_LoggerSchema = new ActionScheduler_LoggerSchema();
$ActionScheduler_LoggerSchema->update_schema_3_0( $table, $db_version );
$table(string) (required)
Name of table being updated.
$db_version(string) (required)
The existing schema version of the table.
