Hello, I would like to create column in loading script base on the source column. My new column should be a flag:
if (isnull(SOURCE), 1, 0)
The problem is that in source data sometimes I have null but sometimes it is space or even several spaces. I tried with TRIM function:
if(isnull(trim(SOURCE)), 1, 0)
but it did not work.
Could you help me please?
