Re: What columns are in the Primary Key

Helmut

ALL_CONS_COLUMNS contains columns and position for each constraint. Similarly ALL_IND_COLUMNS contains columns for each index.

If you need to find the columns through SQL, use the views or join to them. If you don't need the SQL, get a tool like TOAD (free version, http://www.toadsoft.com) and you can find a lot through database - Schema Browser

Hi!

Is there a data dictionary view that gives me all the columns in a primary key of a table?

I can query user_constraints to find out about all constraints on a table:

select * from user_constraints where table_name='TBACCOUNTS'

OWNER CONSTRAINT_NAME C TABLE_NAME SEARCH_CONDITION

---------- ------------------- - ------------ -------------------------
VIVOUSER   SYS_C003011         C TBACCOUNTS   "COMPANYID" IS NOT NULL
VIVOUSER   SYS_C003012         C TBACCOUNTS   "STORELOCID" IS NOT NULL
VIVOUSER   SYS_C003013         C TBACCOUNTS   "ACCOUNTID" IS NOT NULL
VIVOUSER   PK_ACCOUNTS         P TBACCOUNTS

How can I get what columns are in the primary key "PK_ACCOUNTS" ? I have more NOT NULL columns in the table than in the PK.

Any idea?

This is 8.1.6 on Win2k.

Thanks,
Helmut
