Problem Note 40071: Character columns might be padded with a null value when you join two or more ODBC tables
 |  |  |  |
A character column is padded with an extra null value rather than a blank when you increase the column length in the SELECT statement of a join operation that involves two or more ODBC tables.
Example:
libname mssql odbc dsn=odbcdata user=sasdemo pw=saspw;
proc sql;
create table xx as
select x1.txt LENGTH = 6,
x2.id
from mssql.x1, mssql.x2
where x1.id=x2.id;
quit;
If the .txt variable is shorter than 6 bytes in the ODBC table, the value '00'x is appended to the original string.
There is no solution for this problem. However, the problem is fixed in SAS® 9.2.
