Suppose currently we are using a database named "query" which contains the following table -
mysql> Show tables in query; +-----------------+ | Tables_in_query | +-----------------+ | student_detail | | student_info | +-----------------+ 2 rows in set (0.00 sec)
Now, the following is a stored procedure that will Accepts the name of the database as its parameter and gives us the list of tables with the details -
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)
Now call this stored procedure by providing the name of the database as its parameter -
mysql> DELIMITER; mysql> CALL tb_list('query')\G *************************** 1. row *************************** TABLE_CATALOG: def TABLE_SCHEMA: query TABLE_NAME: student_detail TABLE_TYPE: BASE TABLE ENGINE: InnoDB VERSION: 10 ROW_FORMAT: Dynamic TABLE_ROWS: 4 AVG_ROW_LENGTH: 4096 DATA_LENGTH: 16384 MAX_DATA_LENGTH: 0 INDEX_LENGTH: 0 DATA_FREE: 0 AUTO_INCREMENT: NULL CREATE_TIME: 2017-12-13 16:25:44 UPDATE_TIME: NULL CHECK_TIME: NULL TABLE_COLLATION: latin1_swedish_ci CHECKSUM: NULL CREATE_OPTIONS: TABLE_COMMENT: *************************** 2. row *************************** TABLE_CATALOG: def TABLE_SCHEMA: query TABLE_NAME: student_info TABLE_TYPE: BASE TABLE ENGINE: InnoDB VERSION: 10 ROW_FORMAT: Dynamic TABLE_ROWS: 4 AVG_ROW_LENGTH: 4096 DATA_LENGTH: 16384 MAX_DATA_LENGTH: 0 INDEX_LENGTH: 0 DATA_FREE: 0 AUTO_INCREMENT: NULL CREATE_TIME: 2017-12-12 09:52:51 UPDATE_TIME: NULL CHECK_TIME: NULL TABLE_COLLATION: latin1_swedish_ci CHECKSUM: NULL CREATE_OPTIONS: TABLE_COMMENT: 2 rows in set (0.00 sec)
