Resolution:
Environment
-----------------
ALL

If the datatype of a column is CHAR(10) and if the data in this column is just 4 characters then TIBCO ActiveMatrix Adapter for Database while publishing is adding 6 white spaces in the end.

From the Database ManagementSystem documentation, this is the expected behavior for both Sybase and Oracle.Entries shorter than the assigned length are blank-padded for fixed length datatype.  

Workaround
----------------
As an alternative change the column type to VARCHAR or trim the white spaces for those specific columns in the receiving application
