这是一段 SQL 语句，看起来有一些语法错误。根据报错信息，可能是在第六行的语句中，case when 后面缺少了一个 end。你可以在第六行的第二个 count 函数后面加上 end，这样就可以避免这个错误了。同时，在 group by 语句中，可能需要把第二个 count 函数的别名也加入到 group by 语句中，以避免语法错误。

这个SQL语句存在两个问题：

1. `count(case when substr(b.IMSI,1,5)<>46000 and b.operate_code=2 and b.result<>1 then a.IMSI else null end)` 这个计数列在前面已经定义过了，而且它的别名与另一个计数列的别名相同，应该更改其中一个别名。

2. `else count(case when substr(b.IMSI,1,5)<>46000 and b.operate_code=2 and b.result<>1 then a.IMSI else null end)/ count(case when substr(b.IMSI,1,5)<>46000 and b.operate_code=2 then a.IMSI else null end)` 这个计算列的语法有误，应该将它单独作为一个计算列，并且在分母为0时设置默认值0。
