Sql 动态查询,参数不适用于中的何处
我正在oracle上处理动态查询,当我传递where in条件的字符串参数时,它就不起作用了Sql 动态查询,参数不适用于中的何处,sql,database,oracle,oracle10g,where-in,Sql,Database,Oracle,Oracle10g,Where In,我正在oracle上处理动态查询,当我传递where in条件的字符串参数时,它就不起作用了 for x in ( SELECT DISTINCT column_id FROM table WHERE column_id in (in_column_ids) /* WHERE column_id in (15,16,17) =>works */ /*
for x in (
SELECT DISTINCT column_id
FROM table
WHERE column_id in (in_column_ids)
/* WHERE column_id in (15,16,17) =>works */
/* => in_column_ids is a varchar type which
holds comma separated value */
and column_title=in_column_title /* works */
)
在这里,如果我将值直接保存在\u column\u id中,查询就会工作。
但是,作为参数传递的值似乎不适用于中的位置
有什么想法吗?在我看来,你必须用逗号分隔变量。您的查询应如下所示:
for x in (
SELECT DISTINCT column_id
FROM table
WHERE column_id in (
SELECT DISTINCT regexp_substr(in_column_ids,'[^,]+', 1, LEVEL) FROM DUAL
CONNECT BY regexp_substr(in_column_ids, '[^,]+', 1, LEVEL) IS NOT NULL
)
/* WHERE column_id in (15,16,17) =>works */
/* => in_column_ids is a varchar type which
holds comma separated value */
and column_title=in_column_title /* works */
)
