INSERT...RETURNING

MariaDB starting with 10.5.1

INSERT ... RETURNING will be available in MariaDB 10.5.1.

Syntax

INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
 [INTO] tbl_name [PARTITION (partition_list)] [(col,...)]
 {VALUES | VALUE} ({expr | DEFAULT},...),(...),...
 [ ON DUPLICATE KEY UPDATE
   col=expr
     [, col=expr] ... ] [RETURNING select_expr 
      [, select_expr ...]]

Or:

INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
    [INTO] tbl_name [PARTITION (partition_list)]
    SET col={expr | DEFAULT}, ...
    [ ON DUPLICATE KEY UPDATE
      col=expr
        [, col=expr] ... ] [RETURNING select_expr 
      [, select_expr ...]]

Or:

INSERT [LOW_PRIORITY | HIGH_PRIORITY] [IGNORE]
    [INTO] tbl_name [PARTITION (partition_list)] [(col,...)]
    SELECT ...
    [ ON DUPLICATE KEY UPDATE
      col=expr
        [, col=expr] ... ] [RETURNING select_expr 
      [, select_expr ...]]

Description

INSERT ... RETURNING returns a resultset of the inserted rows.

This returns the listed columns for all the rows that are inserted, or alternatively, the specified SELECT expression. Any SQL expressions which can be calculated can be used in the select expression for the RETURNING clause, including virtual columns and aliases, expressions which use various operators such as bitwise, logical and arithmetic operators, string functions, date-time functions, numeric functions, control flow functions, secondary functions and stored functions. Along with this, statements which have subqueries and prepared statements can also be used.

Examples

Simple INSERT statement

INSERT INTO t2 VALUES (1,'Dog'),(2,'Lion'),(3,'Tiger'),(4,'Leopard') 
RETURNING id2,id2+id2,id2&id2,id2||id2;
+-----+---------+---------+----------+
| id2 | id2+id2 | id2&id2 | id2||id2 |
+-----+---------+---------+----------+
|   1 |       2 |       1 |        1 |
|   2 |       4 |       2 |        1 |
|   3 |       6 |       3 |        1 |
|   4 |       8 |       4 |        1 |
+-----+---------+---------+----------+

Using stored functions in RETURNING

DELIMITER |
CREATE FUNCTION f(arg INT) RETURNS INT
    BEGIN
       RETURN (SELECT arg+arg);
    END|

DELIMITER ;

PREPARE stmt FROM "INSERT INTO t1 SET id1=1, animal1='Bear' RETURNING f(id1), UPPER(animal1)";

EXECUTE stmt;
+---------+----------------+
| f(id1)  | UPPER(animal1) |
+---------+----------------+
|       2 | BEAR           |
+---------+----------------+

Subqueries in the RETURNING clause that return more than one row or column cannot be used.

Aggregate functions cannot be used in the RETURNING clause. Since aggregate functions work on a set of values, and if the purpose is to get the row count, ROW_COUNT() with SELECT can be used or it can be used in INSERT...SELECT...RETURNING if the table in the RETURNING clause is not the same as the INSERT table.
