Question

我使用的是Postgres 8.4，我尝试使用

从命令行运行create function ...脚本

psql dbname -U username -f filename

或

psql -f filename -d dbname -U username

并且它总是会导致以下错误

psql：mergenodedata.sql：40：错误：“创建”或附近的语法错误第1行：创建或替换FUNCTION updNode（oldnodename varchar，ne ...

其中第40行是文件的结尾

$$ LANGUAGE plpgsql;

如果我将文件的文件内容剪切并粘贴到pgadmin或打开的psql会话中，那么create function就完美了。

代码是

create or replace FUNCTION updNode (oldnodename varchar, newnodename varchar, scnname varchar, cid integer) returns void AS $$
declare
        oldnodeid integer;
        newnodeid integer;
        scnid integer;
        newcount integer;
        oldcount integer;

BEGIN

raise notice 'doing %', oldnodename;

select id from nodes where nodename = oldnodename and cityid = cid into oldnodeid;
select id from nodes where nodename = newnodename and cityid = cid into newnodeid;
select id from scenario where name = scnname and cityid = cid into scnid;

raise notice 'oldnodeid is %', oldnodeid;
raise notice 'newnodeid is %', newnodeid;
raise notice 'scnid is %', scnid;

select count(*) from collection_node_result where node1id = newnodeid and scenario_collection_id in (
        select id from scenario_collection where scenarioid = scnid into newcount
);

raise notice 'newcount is %', newcount;

select count(*) from collection_node_result where node1id = oldnodeid and scenario_collection_id in (
        select id from scenario_collection where scenarioid = scnid into oldcount
);

raise notice 'oldcount is %', oldcount;


update collection_node_result set node1id = newnodeid where node1id = oldnodeid and scenario_collection_id in (
        select id from scenario_collection where scenarioid = scnid
);


END;
$$ LANGUAGE plpgsql;

它看起来像是破损的文件 - 某些问题可以通过BOM http://en.wikipedia.org/wiki/Byte_order_mark或结束符号＆＃34; ^ z＆＃34;来强制执行。在一些hexeditor中查看文件并检查开始并检查文件结尾。当我使用在其他操作系统上创建的文件时，我遇到了类似的问题。

无法使用psql -f filename选项创建plpgsql函数
