"There was an error or 0 rows updated" I am getting this . But 3 rows were updated in the sql , so I should have gotten the second output with counts of rows updated (i.e. 3)

No you shouldn't.
Your shell script is working just like you have programmed it. Because 3 rows were updated, the test $error_exit not equal to 0 is TRUE:

Code:
if [ $error_exit -ne 0 ]; then # TRUE because $error_exit is 3, which is not equal to 0
    echo "There was an error or 0 rows updated"
 ...
    ...
...

and hence you are seeing the output you have programmed.
