Extend PREPARE and EXECUTE IMMEDIATE to understand expressions

    XMLWordPrintable

Details

    • 10.2.2-3, 10.2.2-1, 10.2.2-2, 10.2.2-4, 10.1.18

    Description

      Currently, PREPARE understands string literals or user variables:

      PREPARE stmt1 FROM 'SELECT 1';
      		 
      SET @s='SELECT 1';
      		 
      PREPARE stmt2 FROM @s;

      We'll extend PREPARE and EXECUTE IMMEDIATE to understand (almost) any kind of expressions:

      PREPARE stmt FROM CONCAT('SELECT * FROM ', table_name);

      Using stored functions and subselects as a prepare source is out of scope of this task.
