The Val function will not fail, because it is not converting, it is simply taking any number values it can find from the PROCESS_LEVEL table field.

I had to use SQL COmmand to say select col1,col2 from table1 where col1=0 so that i return no rows but table only. It seems like SSIS was having issue with time zeros and was trying to do implicit conversions and was showing inconsistent behaviour.Īnother thing i saw that You can not use a table in Destination table list if it has a column of data type timestamp. We think this was the issue and now it should be consistent. So behaviour from SSIS was inconsitent on it. It was working for two days and failed today.
