我有一个触发功能:

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", 'Users');
    RETURN NULL;
END;
$BODY$
LANGUAGE plpgsql;

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

这适用于"用户"表.每当我从"Users"表中删除一行时,数据库就会在"DeletedEntities"表中插入一行("uuidKey","dateCreated","dateModified","dateSynced","username","entityName").我稍后会用于同步目的.

以上工作.这是我的问题,我有大约二十几个表.我知道我需要在每个表上创建TRIGGER,但我不想为每个表创建自定义触发器函数.从上面的第一个函数改变的唯一的东西是函数内INSERT语句中的最后一个值; 而不是'用户',它将是"Ledgers",或"Journal",或其他什么.

在PostgreSQL触发器函数中,如何获取OLD行所属的表的名称？
