Insert individual table_name as column value in all tables

Question

I work with a database that has hundreds of tables with the very same structure and an identical syntax. Everyday more tables are created, thus the database is continuously growing. To dynamically append this growing amount of tables I use a MySQL procedure which works just fine.

Yet once appended I cannot identify the origin of the rows, since the tables don´t contain any information to be distinguished. Hence I would like to integrate a MySQL statement in the following procedure to automatically get the TABLE_NAME from the information_schema and set is as a value in the corresponding table. I already created a column for that, but struggle with the adjustment of the procedure. I would really appreciate any help or suggestion to solve this.

CREATE PROCEDURE getallarbeitsplaene(recordOffset INT, recordCount INT)

BEGIN
    DECLARE tableName VARCHAR(255);
    DECLARE endOfTables INT DEFAULT 0;

    DECLARE cur CURSOR FOR
        SELECT t.table_name
        FROM information_schema.tables t
        WHERE t.table_schema = DATABASE()
          AND t.table_type='BASE TABLE'
                        AND    NOT table_name LIKE '%x_arbeitsplan'
                        AND table_name LIKE '%_arbeitsplan';

    DECLARE CONTINUE HANDLER FOR NOT FOUND SET endOfTables = 1;

    DROP TEMPORARY TABLE IF EXISTS alle_plaene;

    CREATE TEMPORARY TABLE alle_plaene (

This should work

This solution deviates from your version in only a couple of places but here are some points for you to consider

information_schema.table_name is VARCHAR(64).

You don't use either input parameter in your code, so I've dropped them.

You should add the table_name into the temporary table and populate the column with a quoted string within the @s = CONCAT(...) statement.

The ID and AP columns need to be populated in the temp table or dropped entirely, you have them as NOT NULL so they must get a value.

I can't help but wonder why you are creating multiple identical tables each day just to combine the output in a temp table to query altogether, surely a single table solution would be better here.
