Why does SQLite say that instr doesnt exist?

Question

I am trying to run a query:

SELECT name
FROM Foo 
WHERE instr(name, \'@\') = 0 AND instr(name, \'.\') != 0

But I am getting the error: \"no such functio

According to the Change History, the instr function was added in version 3.7.15:

2012-12-12 (3.7.15)

Added the instr() SQL function.

Make sure you're running the latest release.

If upgrading is not an option, you can also use the LIKE operator:

SELECT name
FROM Foo 
WHERE name NOT LIKE '%@%' -- name does NOT contain @
AND name LIKE '%.%';      -- name DOES contain .
