INSTR
INSTR(s1, s2) returns the character position of the substring s2 within the larger string s1. The first character is in position 1. If s2 does not occur in s1 it returns 0.
INSTR('Hello world', 'll') -> 3
In this example you get the position of string 'an' within a country's name.
SELECT name,
POSITION('an' IN name)
FROM bbc
SELECT name,
PATINDEX('%an%', name)
FROM bbc
ORDER BY name
SELECT name,
INSTR(name, 'an')
FROM bbc
