想做一个统计查询，按照日期分组，显示出每天数据出错和设备出错分别有多少个记录数。

数据如下：
RQ BZ
2010-11-24 SJBF
2010-11-24 SJ
2010-11-24 sj
2010-11-24 zx
2010-11-24 ZX
2010-11-25 sj16.17
2010-11-24 sJ14.48起
2010-12-3 wsj 7.47-10.30
2010-12-17 zx到离
2010-12-7 到 ZX
………………

其中BZ里面只要包含SJ的，无论大小写都是数据出错，BZ里面包含ZX，无论大小写都是设备出错。
想要一个这样的表
RQ BZ count
2010-11-24 数据出错 5
2010-11-24 设备出错 2
2010-11-25 数据出错 13
2010-11-25 设备出错 6

SQL code

SELECT rq,'数据出错' bz,Count(*) cnt FROM tab WHERE regexp_like(bz,'sj','i') GROUP BY rq
UNION
SELECT rq,'设备出错' bz,Count(*) cnt FROM tab WHERE regexp_like(bz,'zx','i') GROUP BY rq
[/Quote]

执行SELECT rq,'数据出错' bz,Count(*) cnt FROM tab WHERE regexp_like(bz,'sj','i') GROUP BY rq
，报出错，无效的关系运算符

还是这个通用：
SELECT rq,'数据出错' bz,Count(*) cnt FROM tab WHERE regexp_like(bz,'sj','i') GROUP BY rq
UNION
SELECT rq,'设备出错' bz,Count(*) cnt FROM tab WHERE regexp_like(bz,'zx','i') GROUP BY rq
