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