我遇到了LASTVAL()函数的问题。我有一个触发器:错误:函数lastvar()不存在
CREATE OR REPLACE FUNCTION schema_name.function_name() RETURNS TRIGGER AS
$BODY$
DECLARE
registry_id bigint;
BEGIN
INSERT INTO schema_name.table_name(column1, column2) VALUES (value1, value2);
SELECT LASTVAR() INTO registry_id;
...
当触发器被激发我的错误:
ERROR: function lastvar() does not exist
LINE 1: SELECT LASTVAR()
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
QUERY: SELECT LASTVAR()
CONTEXT: PL/pgSQL function "function_name" line 5 at SQL statement
表中有一个序列作为默认值的PK列:
...
table_name_id bigint NOT NULL DEFAULT nextval('table_name_seq'::regclass),
...
谢谢你,我正在寻找15分钟为什么这个函数确实存在。我不敢相信我这样做是错的。 – hschimpf 2012-07-06 15:57:37
