CreateTrigger

public CreateTrigger(SQLParser.Create_trigger_statementContext ctx,
 PgDatabase db,
 ISettings settings)

Constructs a new CreateTrigger parser.

Parameters:

ctx - the CREATE TRIGGER statement context

db - the PostgreSQL database object

settings - the ISettings object

Method Details

parseObject

public void parseObject()

Description copied from class: ParserAbstract

Parses a database object from the current context. Must be implemented by concrete subclasses to handle specific object types.

Specified by:

parseObject in class ParserAbstract<PgDatabase>

parseWhen

public static void parseWhen(SQLParser.When_triggerContext whenCtx,
 PgTrigger trigger,
 AbstractDatabase db,
 String location)

Parses the WHEN clause of a trigger definition.

This method processes trigger conditions that determine when the trigger should fire based on the values in the affected row.

Parameters:

whenCtx - the WHEN trigger context, may be null

trigger - the trigger object to configure

db - the database for analysis launchers

location - the source location for error reporting
