Problem in executing command at plugin install

Hello,

I have created an MYSQL procedure.
it is successfully executing on MYSQL manually.

But when I am executing at the time of the plugin install it will give me an error.
This is the MYSQL procedure.

DELIMITER $$
CREATE PROCEDURE `NH_SP_GetProductIds` 
(  
  `tmpId` INT,  
    `StoreId` INT 
) 
  
    READS SQL DATA 
    SQL SECURITY INVOKER
BEGIN      
    SET @sql_command = '';
    
    drop temporary TABLE if exists ProductIdsTable;
    CREATE TEMPORARY TABLE ProductIdsTable (
    ProductId INT
  );
    
    SET @sql_command = '
    INSERT INTO ProductIdsTable (ProductId)
    SELECT DISTINCT 
      p.Id AS ProductId
    FROM Product p';
    
    PREPARE sql_do_stmts FROM @sql_command;
  EXECUTE sql_do_stmts;
  DEALLOCATE PREPARE sql_do_stmts;
END$$
DELIMITER ;

Inside Install method

var filePath = _fileProvider.MapPath("~/Plugins/{plugin}/Procedure/MySQL.StoredProcedure.sql");
            if (!_fileProvider.FileExists(filePath))
                return;

            data.ExecuteSqlScript(_fileProvider.ReadAllText(filePath, Encoding.Default));

I am getting this error.
Parameter '@sql_command' must be defined.
