ssis, conditional split DT_BOOL NULL

 Section[DT_STR]   flag(DT_BOOL)
     sec a            1
     sec b            0
     sec c            1
     sec d

I am importing data from excel sheet by using SSIS package. I have two coloumn as above and i am using data convertion to convert the data to string[DT_STR] and [DT_BOOL] I am using conditional split to split in 4 cases..

 case1-    Included section:[flag] == (DT_BOOL)"False"
 case2-    excluded section:[flag] == (DT_BOOL)"True"
 case3-    null section name:ISNULL([Section])

The 4th case is to handle the null values in the flag coloumn. how can i handle the null values in the flag coloumn?

I am trying something like [flag] == NULL(DT_BOOL) but my package fails when there is a null or a blank cell in excel sheet. How can i handle those value?

1 answer: sort voted first

with conditional splits, the order of the cases is very important. if you put in case 4 and just do a ISNULL(Section) in the condition and then move it up to the first case, then it will work.

Just a quick note with your cases in the example, the 3rd case where section name is null will never be checked because the first 2 will take precedence over the last one. If you want the null sections to be moved somewhere else, then move it before the flag checks.

Hope this helps!

EDIT: If you want null flags to be evaluated to FALSE, you can change your data conversion transform to a derived column transform, then you don't need the ISNULL(flag) in the conditional split. Enter the Expression for the Flag as, where F2 is the column name from the spreadsheet

 ISNULL(F2) ? (DT_BOOL)"False" : (DT_BOOL)F2
