String & Binary Functions (Matching/Comparison)

ILIKE ANY

Allows case-insensitive matching of strings based on comparison with one or more patterns.

The operation is similar to LIKE. If the input string matches any of the patterns, this returns the input string.

See also:

LIKE , LIKE ANY

Syntax

<subject> ILIKE ANY (<pattern1> [, <pattern2> ... ] ) [ ESCAPE <escape_char> ]

Arguments

Required:

subject

The string to compare to the pattern(s).

pattern#

The pattern(s) that the string is to be compared to. You must specify at least one pattern.

Optional:

escape_char

Character(s) inserted in front of a wildcard character to indicate that the wildcard should be interpreted as a regular character rather than as a wildcard.

Returns

The data type of the returned value is VARCHAR.

Usage Notes

  • SQL wildcards are supported in pattern:

    • An underscore (_) matches any single character.

    • A percent sign (%) matches any sequence of zero or more characters.

  • Wildcards in pattern include newline characters (\n) in subject as matches.

  • The pattern is considered a match if the pattern matches the entire input string (subject). To match a sequence anywhere within a string, start and end the pattern with %, for example ‘%something%’.

  • NULL does not match NULL. In other words, if the subject is NULL and one of the patterns is NULL, that is not considered a match.

  • If the function is used with a subquery, the subquery should return a single row.

    For example, the following should be used only if the subquery returns a single row:

    SELECT ...
        WHERE x LIKE ANY (SELECT ...)
    

Examples

This shows how to use ILIKE ANY:

Create a table that contains some strings:

CREATE OR REPLACE TABLE ilike_example(subject varchar(20));
INSERT INTO ilike_example VALUES
    ('jane doe'),
    ('Jane Doe'),
    ('JANE DOE'),
    ('John Doe'),
    ('John Smith');
SELECT * 
  FROM ilike_example 
  WHERE subject ILIKE ANY ('jane%', '%SMITH')
  ORDER BY subject;
+------------+
| SUBJECT    |
|------------|
| JANE DOE   |
| Jane Doe   |
| John Smith |
| jane doe   |
+------------+
