So far, tried these methods above but produced:

text1, 10
text2, 12

It seems that these queries produce a result that corresponds to _each
row_ value being evaluated against the target value. The desired
output is that the sum of the values in the result is to be evaluated
against the target. But thanks anyway so far.
