How to handle NULL value output from ISQL command?
I am using ISQL command in ksh script.
Suppose if i get NULL value from the query which i run,how can i handle it?
I am getting a NULL result set and the following error is coming.
Code:
############### output of isql command for getting the sum of JEs ################
-----------
NULL
(1 row affected)
############ Checking if count is blank ###########
NULL
retrieveCheck.ksh[159]: ^J NULL : 0403-009 The specified number is not valid for this command.
The code is:
Code:
blank=""
isql -UUSER -PPW -SSERVER -i$tempSQL2 -w1000 -o$sumOfJEOutputFile
retval=$?
echo $retval
if [[ $retval != 0 ]]; then
echo "Failed to connect to the Archive Database" | mail -s "ERROR OCCURED:Database connection Failed" "akanksha.kumari@libertymutual.com"
exit 0
else
echo "Database connection successful."
fi
echo "coming out of isql command"
echo "############ output of isql command for getting the sum of JEs ################"
cat $sumOfJEOutputFile
egrep -v "row affected|rows affected|------|^ |return status" $sumOfJEOutputFile > $actualCount
#######################################################################
## Assigning the total number of JE count to a variable count
#######################################################################
count=$(cat $actualCount | tr -s "\t" " ")
echo "############## Checking if count is blank #################"
echo $count
if [[ $count -eq $blank ]]; then ## In this line error is coming line number 159
echo "Count is Blank."
exit 0
else
echo "count is not blank"
fi
So i want to know how can i handle this null result set and send a mail to notify that null value is coming.
Using a ksh script, I'm dumping the data from our sybase database into an output file. This output file is for what ever reason cut at 2GB.
There is enough space on the unix machine and as there is no error message is received I have no clue to start looking for a solution.
