问题:

I want to export data from db2 tables to csv format.I also need that first row should be all the column names.

I have little success by using the following comand

EXPORT TO "TEST.csv" 
OF DEL 
MODIFIED BY NOCHARDEL coldel: ,
SELECT col1,'COL1',x'0A',col2,'COL2',x'0A' 
FROM TEST_TABLE;

But with this i get data like

Row1 Value:COL1:
Row1 Value:COL2:
Row2 Value:COL1:
Row2 Value:COL2:

etc.

I also tried the following query

EXPORT TO "TEST.csv" 
OF DEL 
MODIFIED BY NOCHARDEL 
SELECT 'COL1',col1,'COL2',col2 
FROM ADMIN_EXPORT;

But this lists column name with each row data when opened with excel.

Is there a way i can get data in the format below

COL1   COL2
value  value
value  value

when opened in excel.

Thanks

After days of searching I solved this problem that way:

 EXPORT TO ...
 SELECT 1 as id, 'COL1', 'COL2', 'COL3' FROM sysibm.sysdummy1
 UNION ALL
 (SELECT 2 as id, COL1, COL2, COL3 FROM myTable)
 ORDER BY id

You can't select a constant string in db2 from nothing, so you have to select from sysibm.sysdummy1. To have the manually added columns in first row you have to add a pseudo-id and sort the UNION result by that id. Otherwise the header can be at the bottom of the resulting file.
