Find table name on the database using stored procedure on MySql 8.0.17

Hi,

This is a list name of tables stored a database MySql version 8.0.17

+------------------+| listTable        |+------------------+| Table_A2_11_2021 || Table_L7_12_2021 || Table_C3_1_2021  || Table_D8_10_2021 || Table_T0_11_2021 || Table_E9_3_2021  || Table_L4_2_2021  || Table_O1_12_2021 || Table_P2_5_2021  || Table_Q2_10_2021 || Table_A3_12_2021 || Table_S5_9_2021  || Table_T8_11_2021 || Table_Q6_1_2021  |+------------------+

The table name storage policy is

• Table_
• Western alphabet letter (issued by an algorithm that recognizes the connected user, privileges, etc.)_
• Random number_
• Month Number_
• Current Year

I need find on the database MySql all the table for first Western alphabet letter without Random_number for this return

+-----------------+| listTable       |+-----------------+| Table_A_11_2021 || Table_L_12_2021 || Table_C_1_2021  || Table_D_10_2021 || Table_T_11_2021 || Table_E_3_2021  || Table_L_2_2021  || Table_O_12_2021 || Table_P_5_2021  || Table_Q_10_2021 || Table_A_12_2021 || Table_S_9_2021  || Table_T_11_2021 || Table_Q_1_2021  |+-----------------+

I have idea to use this Stored Procedure below but I just can't extract first Western alphabet letter without Random number.

CREATE DEFINER=`root`@`%` PROCEDURE `SP_SIX_MONTHS`()BEGINDECLARE tyear INT(4);DECLARE tmonth INT(2);SET tyear =YEAR(CURDATE());SET tmonth =MONTH(DATE_SUB(CURDATE(),INTERVAL6MONTH));SET@s= CONCAT('SELECT 
                 FROM information_schema.TABLES 
                 WHERE table_name LIKE ''table#_',???,'%#_',tmonth,'#_',tyear,''' ESCAPE ''#'';');                       PREPARE stmt FROM@s;EXECUTE stmt;DEALLOCATEPREPARE stmt;END
