GROUP_CONCAT_UNQUOTED

This function concatenates multiple strings into a single string, where each value is separated by the optional separator parameter. If separator is omitted, then this function returns a comma-separated string.

Syntax

GROUP_CONCAT_UNQUOTED('str' [, separator])

Example

SELECT

  GROUP_CONCAT_UNQUOTED(x)

FROM (

  SELECT

    'a"b' AS x),

  (

  SELECT

    'cd' AS x);

Unlike GROUP_CONCAT, this function will not add double quotes to returned values that include a double quote character. In the example above, the string a"b would return as a"b.
