SELECT cols.table_name, cols.column_name, cols.position, cons.status, cons.owner, cols.constraint_name

FROM all_constraints cons, all_cons_columns cols

WHERE cols.table_name = 'IGCB_CODE_BANK'

AND cons.constraint_type = 'P'

AND cons.constraint_name = cols.constraint_name

AND cons.owner = cols.owner

ORDER BY cols.table_name, cols.position;



查看列    select * from cols

查看列    select * from user_tab_columns where table_name=''  

查看约束    select * from user_constraints
