Use the COLLECT STATISTICS statement to define the table columns on which you want to collect statistics, for example:

COLLECT STATISTICS ON  database_name.table_name  COLUMN (column_1,  column_2  ...);

At minimum, you should collect statistics on the primary index (PI) of each table. For small tables (<100 rows per AMP) PI statistics may be sufficient.
