Just some String variable like: “Project Code”, “Continent”, “Order Number”(it’s String),etc.
I also checked the excel that the type of the issue row of data whether different than the other row of data, but they are same.
And also I just found that when I was trying to figure out whether my condition of select are wrong so that I separate them to one by one to check the result.
The error message suddenly disappear and the process worked successfully.
However, I still need to figure out the reason why this happen to avoid the following exception in the future.
Finally I solve the issue, not sure the possible reason is correct or not.
Reason: Probably because of Timeout.
I guess it might took too much time to search the data with 5 condition inside one select statement which made me confused that my data only have 800 row total.
After I separate these 5 condition to one by one, and the issue disappear.
