I created a script to read a csv file with four columns. The script also saved values of each col in a arry.
In the script, i connected to db try to run a query to pull out data baisc on the values from the csv file.

select Num from tableName
where Sec_Num in ('${isin[@]}') /*isin[@] is an arry which its data are from extracted from the csv file.

could you please tell me what wrong with this query. When I run the script,it is unable to pull out any data from db. Do you have any suggestion?

Thanks You!
