table alias from previous statement interferes later commands

Details

    Description

      When an Update Statement happens with an alias. The alias seems to replace the table name.

      See below an example Query to reproduce the failure:

      DROP TABLE IF EXISTS `test_table`;
      		 
       
      		 
      CREATE TABLE `test_table` (
      		 
        `id` int NOT NULL AUTO_INCREMENT PRIMARY KEY,
      		 
        `order_date` datetime NOT NULL,
      		 
        `language_id` BINARY(16) NULL 
      );
      		 
       
      		 
      ALTER TABLE `test_table` CHANGE `order_date` `order_date_time` DATETIME(3) NOT NULL;
      		 
       
      		 
      ALTER TABLE `test_table` ADD COLUMN `order_date` DATE GENERATED ALWAYS AS (CONVERT(`order_date_time`, DATE)) STORED AFTER `order_date_time`;
      		 
       
      		 
      UPDATE `test_table` as `x` SET order_date = NULL;
      		 
       
      		 
      ALTER TABLE `test_table` MODIFY COLUMN `language_id` BINARY(16) NOT NULL;

      Results in the following error on the ALTER TABLE statement:

      Unknown column '`test`.`x`.`order_date_time`' in 'GENERATED ALWAYS'
