A table may have multiple foreign keys
A table cannot have more than one set of attributes specified as the primary key, and the columns of a primary key cannot contain null values.
The max number of columns in a table is 750
The max number of tables in a join is 225
Normally this is depended on the max page size and max length of the row in DB2.
NOTE : THESE NUMBERS ALTER AS PER THE DB2 VERSION THIS INFO IS AS PER VER 8.0 I BLIVE.
Thanks
