And Google explains "The term 'sargable' is a portmanteau of "Search ARGument ABLE," formed by combining the words from a SQL database context."
Consider the Simple example it presents. The article is in effect implying that no query optimiser would be able to figure out the equivalence of the two predicates.
(Let's ignore that the two predicates aren't actually equivalent; the first version may raise an exception if myIntColumn is negative, depending on the DBMS.)
Ozar's article is much better. It doesn't make sweeping assumptions about the limitations of all query optimisers, or basic oversights in contrasting supposedly equivalent predicates.
I've been working with SQL for 20+ years, and have literally never come across that word a single time in any documentation, tutorial, Stack Overflow answer, or here on HN. Working in Postgres, MySQL and SQLite.
Is it used at some particular company, or open source community, or with a particular database, or something?
