Description:
In our production environment, there are four tables to do association queries.
There are exists in the conditions, and we found that the first two conditions
were lost.
The following two conditions are missing：
{color:#f79232}t2.cust_no is null and t4.cust_level not in ('4','5'){color}
In the test environment, I prepared the data of the following four tables, and
a condition was lost in the simulation.
