Question

I have a table that looks like:

ATTRIBUTE1 | ATTRIBUTE2
weight: 190| height: 175
ctr: 400   | dmd: 19

Is it possible to do comparative operations on these fields?

Like, if I wanted to find everyone with a weight less than 200, what would the syntax look like for that? I figure the query would look like the following, if there were no text in the field:

SELECT * FROM mytable WHERE attribute1 < '200'

But since the field has the defining text “weight:”, I’m not quite sure how to do this.

Answer 1

where cast(substring(ATTRIBUTE1, instr(ATTRIBUTE1, ': ')+1 ) as unsigned) <200

alternative:

where cast(replace(Field_2, 'weight: ', '') as unsigned) > 180
