Problem Solving db2cc
—————————————————
Type in this command in terminal.

db2inst1@ubuntu:/home/xyiry$ xhost +
db2inst1@ubuntu:/home/xyiry$ su db2inst1
db2inst1@ubuntu:/home/xyiry$ export DISPLAY=:0.0
db2inst1@ubuntu:/home/xyiry$ db2cc

Hope it works…

1) First of all make sure you already login as a db2admin or db2 privilege user.

2) Secondly key in -> db2 EXPORT TO file.del of DEL ‘ select * from yourtablename’

3) You’re done. It will export your file into a comma separated value file or known as a CSV format file.

By Zairy

I’m assuming you guys are running db2 on Unix platform. So make sure you login as a DB2 Administrator.

For my case I logged in as db2inst1

Steps:

1) su db2inst1

2) db2 connect to databasename

3) mkdir /usr/db2backup

4) db2 backup db databasename to /usr/db2backup

So that’s all for db2 backup.

# DB2 Date Format :
2008-03-24 16:38:58.623431

Lets say, the Field that stores the date is in db2 time stamp format and you want to format it , you can use this simple way to solve that :

Example 1

select Year (DATEFIELD) from TABLENAME
select Month (DATEFIELD) from TABLENAME
select day (DATEFIELD) from TABLENAME

Example 2

select Year(FDTARIKH),MONTH(FDTARIKH),day(FDTARIKH) from TBLOGLOGIN
