Priority of AND and OR operator in Mysql select query [closed]
Yes, AND has higher precedence than OR. x and y are bound together, m and q are bound together, then the resulting expressions are ORed.
AND has a higher priority than OR in every programming language I have ever seen, and I've seen several dozen at close quarters, and implemented a few myself. This question was basically settled in 1960 with the Algol-60 report, if not already in Fortran (1957).
[There was one exception but it was a mis-implemented language with no operator precedence at all. I fixed that.]
Yes it will do something like (X AND Y) OR (M AND Q). AND operator's priority is higher than OR.
