MySQL Function

43.1k

A function in MySQL is a stored programme into which you can pass parameters and get a value back.

A stored function and user-defined functions are created with the CREATE FUNCTION statement. A stored function is a collection of SQL statements that perform a single task and return a single result. It can be called from within a Mysql statement, just like the built-in function in MySQL.

  • String Functions. ASCII CHAR_LENGTH CHARACTER_LENGTH CONCAT CONCAT_WS FIELD FIND_IN_SET FORMAT INSERT INSTR LCASE.
  • Numeric/Math Functions. ABS ACOS ASIN ATAN ATAN2 AVG CEIL CEILING COS COT COUNT DEGREES.
  • Date/Time Functions.
  • Advanced Functions.

AVG, COUNT, SUM, MIN, DATE, and other functions can be used with select statements in SQL. Every time a function is called, it compiles. A value or result must be returned by functions. Only input parameters are used by functions. In functions, try and catch statements are not utilised.
