Dear All,
I have an SSIS package that at some point does un union.
All the columns from that union are str with size 3 but the output variable appears with size 50
for example:
SECURITY CURRENCY (input1) SECURITY CURRENCY (intput2) SECURITY CURRENCY (Output)
Both SECURITY CURRENCY inputs are size 3 but the outup is size 50.
Can someone help?
Thank you

Help with what, exactly?

Understanding why the length is not 3?
Understanding how to change the length to 3?
Understanding why this is not necessary going to cause any errors?
something else?

Hello,

Thank you for your answer.

I would like to understand how can I change it from 50 to 3 in order to not get this warning

Right click on the data source and 'Show Advanced Editor'.
Navigate to Input and Output Properties/OLEDB Source Output/Output Columns and select the column whose length needs to be changed
Change the length in the right-hand pane and save

OK. I'm guessing that you don't require any further help with this though, given the lack of detail you have provided.

Union all is holding on to metadata where you had one of the inputs defined differently, after getting both inputs to the same length delete the union all and pull another union all in. This will grab the updated metadata. There is no advanced editor for a union all.
