SQL provides the function LOCATE() which can be used to locate an exact substring within a larger string. The syntax for LOCATE() is:

LOCATE(substring, string, start_position)

where substring is the exact substring you are trying to locate, string is the larger string you are searching within, and start_position is the position in the string where you want to begin the search (optional, defaults to 1).

For example, to find the position of the substring "love" within the string "I love SQL", we would use the following query:

SELECT LOCATE('love', 'I love SQL');

This would return the value 3, indicating that the substring "love" starts at the third character position within the string "I love SQL".
