Help with awk

Hi Guys,,

I am assigning a query result to a variable.

variable=`db2 -x "select col1 from table1 | awk '{print $1}'`

The problem is if i execute the above command without awk. I am getting an value. But if i execute with awk command, i am getting an error, saying
A database connection does not exists.

I want the awk command to be used.

Please help me.

Thanks for your help in advance,
Magesh

I am sure that,

Code:
variable=`db2 -x "select col1 from table1"`
( with out awk )

also wont return anything and ther is some issue with the data base connectvity. Because the next awk statemnt is nothng to do much other than priting.

correct panyam, i too thought so. When i execute it in the command line. i am getting the value. But when i put it in the script, the value is not getting assigned to the variable.
The code in the scripts is
PREVIOUS_QTR=`db2 -x "SELECT statement"`
PREVIOUS_QTRAPPLBTY= `echo "$PREVIOUS_QTR" | awk '{print $1}'`
echo $PREVIOUS_QTRAPPLBTY

in the verbose mode, i got this

PREVIOUS_QTR= 200901

PREVIOUS_QTRAPPLBTY= `echo "$PREVIOUS_QTR" | awk '{print $1}'`
+ awk {print $1}
+ echo 200901
+ 200901
+ PREVIOUS_QTRAPPLBTY=
genTmGapQTR.ksh[22]: 200901: not found.
echo $PREVIOUS_QTRAPPLBTY
+ echo


Please help me.. in this

remove the space after the "=". I can see a single space after =.
