Returns an integer representing the starting position of the first occurrence of
a pattern in a string.
PATINDEX ( '% pattern %', string_expression )
pattern The pattern to be searched for. If the leading percent wild card is
omitted, PATINDEX returns one (1) if the pattern occurs at the beginning of
the string, and zero if not.
The pattern uses the same wild cards as the LIKE comparison. These are as
follows:
Wild card Matches
_ (underscore) Any one character
% (percent) Any string of zero or more characters
[] Any single character in the specified range or set
[^] Any single character not in the specified range or set
string-expression The string to be searched for the pattern.
The following statement returns the value 2.
SELECT PATINDEX( '%hoco%', 'chocolate' )
The following statement returns the value 11.
SELECT PATINDEX ('%4_5_', '0a1A 2a3A 4a5A')
PATINDEX returns the starting position of the first occurrence of the
pattern. If the pattern is not found, it returns zero (0).
