Look at the indexes. Use X on the line where the table is displayed. You should get a screen like the following.
| Code: |
DB2 Admin --------------------- D2WA Indexes ----------------- Row 1 to 1 of 1
Command ===> Scroll ===> CSR
Commands: DIS STA STO
Line commands:
T - Tables D - Database G - Storage group P - Plans C - Columns
DIS - Display index space STA - Start index space STO - Stop index space
? - Show all line commands
Index Table C C C
Select Index Name Owner Table Name Owner U Cols G D L T
* * * * * * * * * *
------ ------------------ -------- ------------------ -------- - ------ - - - -
IDX1 OWNER TABLE_NAME_T OWNER P 2 Y N Y 2
|
a P in the U column indicates it is a primary key. Check the help on this screen for what the data means. |

| A table can have a primary key and a foreign key in a database. Anything else is referred to as an Index and using X on the line showing the table you want will give you the indexes for that table. Once you get the indexes you put a C in front of the index name to get the columns in that index. |
