ERROR: The length of the value of the macro variable NWID (987973) exceeds the maximum length (65534). The value has been truncated
to 65534 characters.
I thought all distinct values will be selected into nwid macro.
This example is contrived but shows what you "could" do.
I'm not sure you need the double ampersand.
This example is contrived but shows what you "could" do.
All distinct values will be selected but your string must be longer than the 65k character length.
You can check if that is the case by calculating the number of distinct network ID and then multiplying by 3+ length of network id: total length ~ # of distinct * (length of networkID + 3).
If thats close to 65K then you have a problem.
Ok..If it greater than 65K sas cannot handle isnt it
You don't need the macro variable.
You can use a subquery as shown by Data _null_ or create a macro like identified in this link:
39605 - Create a string that goes beyond the 64K limit for macro variables
I'd go with a subquery, since both tables seem to be in the same location and it would be the fastest.
