How can I get the table name in a PostgreSQL trigger function?

Question

I have a trigger function:

CREATE OR REPLACE FUNCTION \"trigger_deleteUsers\"()
RETURNS trigger AS
$BODY$
BEGIN
    INSERT INTO \"DeletedEntities\" (\"uuidKey\",         


        

Answer 1

try this:

TG_TABLE_NAME::regclass::text

I use it with version 9.4 but it should be working from 8.4 up.

Here is your code with this change:

CREATE OR REPLACE FUNCTION "trigger_deleteUsers"()
RETURNS trigger AS
$BODY$
BEGIN
  INSERT INTO "DeletedEntities" ("uuidKey", "dateCreated", "dateModified", "dateSynced", "username", "entityName")
  VALUES (OLD."uuidKey", OLD."dateCreated", OLD."dateModified", "dateSynced", OLD."username", TG_TABLE_NAME::regclass::text);

  RETURN NULL;
END;
$BODY$
LANGUAGE plpgsql;

CREATE TRIGGER "deleteUsers" AFTER DELETE ON "Users" FOR EACH ROW EXECUTE 
PROCEDURE "trigger_deleteUsers"();

let me know if it helps!
