LOCATE()

Synopsis

LOCATE(substr, str, pos)

Returns the position of the first occurrence of substr in the string str. If the parameter pos is passed, the search begins at position pos. If substr is not found in str, a value of 0 is returned. This code returns the values 5 and 11, because the first function call returns the first encounter of the word “unit,” while the second one only starts to search at the seventh character, and so returns the second instance:

SELECT LOCATE('unit', 'Community unit');
SELECT LOCATE('unit', 'Community unit' 7);
