我无法运行此程序。 你能帮我在哪里做错了吗?
【问题讨论】:
去掉code text,
上的逗号即可。
感谢您的回复。这是经过编辑的代码,但代码文本后的逗号不是问题。我得到 ----------- 从 123 位置开始的未终止美元报价。预计终止 $$
你使用什么客户端?.. 上面的错误在我看来不像是 postgres
***.com/questions/3499483/…
我正在使用 DbSchema
【参考方案1】:
我正在使用松鼠,并面临与您相同的问题。 直到我发现:
-- Note that if you want to create the function under Squirrel SQL,
-- you must go to Sessions->Session Properties
-- then SQL tab and change the Statement Separator from ';' to something else
-- (for intance //). Otherwise Squirrel SQL sends one piece to the server
-- that stops at the first encountered ';', and the server cannot make
-- sense of it. With the separator changed as suggested, you type everything
-- as above and end with
-- ...
-- end;
-- $$ language plpgsql
-- //
--
-- You can then restore the default separator, or use the new one for
-- all queries ...
--
