SEPARATOR
SEPARATOR is a MySQL function used in conjunction with the GROUP_CONCAT() function. It defines a delimiter to separate concatenated strings that result from a query. By default, the delimiter is a comma, but you can specify your own delimiter using the SEPARATOR clause.
Example
SELECT GROUP_CONCAT(name SEPARATOR '; ')FROM users;Output
John Doe; Jane Doe; Richard Roe; John StilesExplanation
In the provided example, the GROUP_CONCAT function is used to concatenate all the values from the name column of the users table. The SEPARATOR clause within the GROUP_CONCAT function is used to define the delimiter that separates the values, in this case, a semicolon ’;’ followed by a space. Therefore, the result is a string of all name column values separated by a semicolon and a space.
