Hi Guys,
Can you please let me know how to set default value to a column.
Select <C1>, <C2> from table1.
I want to set default value to column c2 irrespective of the data the table contains.
Regards,
JR |

Hello,
Just to make sure we are all thinking the same way. . . .
This

will force the default value into the result from the execution of that select.
The data in the table will not contain the "default value" after that select is executed. A subsequent "SELECT C1, C2 FROM TABLE1" will not return the "defalut value", it will return whatever values were in C2 in the table. |

Rajandhla,
Clarify your question!

| How to set default value to column ? |
is not the question for the answers you got.
Shall I restate your question as
How to get a common value in place of one column for all the result rows?

 It is possible. The query format is the same as sandeep1dimri had given.
 Note: A common value not default value: "Default" is to fill up an absence of a requisite data

 But why? You can initialize your host variable with that default value before fetch. For this simple purpose, do not change your query to give DB2 an extra task?? |

So you want to fetch the default value in your cursor and also push that default value back to the actual database?
The first solution give will set the value in your cursor only. If you want to push that value back to the database, you need to execute an UPDATE to push the value back to the table.
Use your SELECT cursor to read the values out to working storage with your default value for COLUMN2. Then use your UPDATE command to change the actual table.
| Code: |
*Declare SELECT cursor to have this SQL
SELECT COL1,
'DefaultValue'
FROM TABLE1
WHERE COL1 = :WS-COL1Lookup
*Open the cursor
EXEC SQL FETCH select-cursor-name
INTO :WS-COL1,
:WS-COL2
END-EXEC.
EXEC SQL
UPDATE TABLE1
SET COL2 = :WS-COL2
WHERE COL1 = :WS-COL1
END-EXEC.
