创建一个MySQL存储过程，该存储过程以数据库名称作为参数，列出特定数据库中包含详细信息的表。

假设当前我们使用一个名为“query”的数据库，其中包含以下表格 -

mysql> Show tables in query;
+-----------------+
| Tables_in_query |
+-----------------+
| student_detail  |
| student_info    |
+-----------------+
2 rows in set (0.00 sec)

现在，以下是一个存储过程，它将接受数据库的名称作为其参数，并为我们提供包含详细信息的表列表 -

mysql> DELIMITER//
mysql> CREATE procedure tb_list(db_name varchar(40))
   -> BEGIN
   -> SET @z := CONCAT('Select * from information_schema.tables WHERE table_schema = ','\'',db_name,'\'');
   -> Prepare stmt from @z;
   -> EXECUTE stmt;
   -> END //
Query OK, 0 rows affected (0.06 sec)

现在通过提供数据库名称作为其参数来调用此存储过程 -

mysql> DELIMITER;
mysql> CALL tb_list('query')\G
