出现错误 ORA-00909: 参数数量无效 [英] Getting error ORA-00909: invalid number of arguments
本文介绍了出现错误 ORA-00909: 参数数量无效的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
CREATE VIEW ITCC.release_testcase_count
AS
(
SELECT CONCAT(rtm.requirement_id,'-',tct.release_id) AS id,
rtm.requirement_id AS requirement_id,
tct.release_id AS release_id,
COUNT(tct.release_id) AS testcase_count
from testcase_version tcv
INNER JOIN tcr_catalog_tree_testcase tct ON tcv.id = tct.testcase_version_id
LEFT JOIN requirement_testcase_mapping rtm ON rtm.testcase_id=tcv.testcase_id
GROUP BY tct.release_id , rtm.requirement_id
);
相同的查询适用于 ms sql 和 my sql,没有任何语法错误.我也想在 oracle 中执行它,但我遇到了同样的错误
same query is working for ms sql and my sql without any syntax error. i want to execute it in oracle as well but i am getting error for the same
推荐答案
Oracle CONCAT
函数只需要两个,而不是三个或更多参数.不使用 CONCAT
,只需使用连接运算符:
The Oracle CONCAT
function only takes two, not three or more, parameters. Instead of using CONCAT
, just use the concatenation operator:
CREATE VIEW ITCC.release_testcase_count AS (
SELECT rtm.requirement_id || '-' || tct.release_id AS id,
...
)
或者,如果您真的想在这里使用 CONCAT
,那么您可以将它们链接在一起:
Or, if you really want to use CONCAT
here, then you may chain them together:
CREATE VIEW ITCC.release_testcase_count AS (
SELECT CONCAT(rtm.requirement_id, CONCAT('-', tct.release_id)) AS id,
...
)
