Hello fellow developers,
I need help determining the meaning of an expression in SSIS using the Derived Column tool. I am trying to fix an error in a SSIS package that was created by a previous developer. I need help understanding what the following expression is accomplishing and to create the expression is SQL.
(LEN(TRNFC#) == 10) ? (DT_WSTR,8)((DT_WSTR,4)((DT_I4)SUBSTRING(TRNFC#,7,4)) + "_" + (DT_WSTR,3)TRNVSEQ) : (DT_WSTR,8)"0-0"
A sample of the data in field TRNFC# before being altered looks like this: 3579000017
A sample of the data in field TRNVSEQ before being altered looks like this: 0
A sample of the result data is 17_0
What would be this expression in a SQL select statement?
Thanks in advance!
