Answer 1

The Quickest solution to Update/Reset AUTO_INCREMENT in MySQL Database

Ensure that the AUTO_INCREMENT column has not been used as a FOREIGN_KEY on another table.

Firstly, Drop the AUTO_INCREMENT COLUMN as:

ALTER TABLE table_name DROP column_name

Example: ALTER TABLE payments DROP payment_id

Then afterward re-add the column, and move it as the first column in the table

ALTER TABLE table_name ADD column_name DATATYPE AUTO_INCREMENT PRIMARY KEY FIRST

Example: ALTER TABLE payments ADD payment_id INT AUTO_INCREMENT PRIMARY KEY FIRST

Answer 2

I have written below procedure change the database name and execute the procedure

CREATE DEFINER=`root`@`localhost` PROCEDURE `setAutoIncrement`()
BEGIN
DECLARE done int default false;
    DECLARE table_name CHAR(255);
DECLARE cur1 cursor for SELECT t.table_name FROM INFORMATION_SCHEMA.TABLES t 
        WHERE t.table_schema = "buzzer_verifone";

    DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
    open cur1;

    myloop: loop
        fetch cur1 into table_name;
        if done then
            leave myloop;
        end if;
        set @sql = CONCAT('ALTER TABLE ',table_name, ' AUTO_INCREMENT = 1');
        prepare stmt from @sql;
        execute stmt;
        drop prepare stmt;
    end loop;

    close cur1;
END

Execute the procedure above using below line

Call setAutoIncrement();
