Question

有人可以向我解释如何在PostgreSQL（pl / pgsql）中使用UTL_FILE包。每次我查询时都会出现此错误

表＆＃34; utl_file＆＃34;`：
缺少FROM子句条目

这是我的代码：

CREATE OR REPLACE FUNCTION xxxxxx(
    IN strficname text,
    IN lnguser bigint,
    IN lngproduct bigint,
    IN lnginsurer bigint,
    IN lngregion bigint,
    OUT intstat1 bigint,
    OUT intstat2 bigint,
    OUT intstat3 bigint,

    OUT intstat7 bigint,
    OUT intstat8 bigint,
    OUT intstat9 bigint,
    OUT strrejfilename text)

Answer 1

documentation似乎表明正确的调用约定是RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule /dev/(.+)$ http://example.com/$1：

utl_file.fclose_all()

pl / pgsql中的UTL_FILE
