执行 SHOW CREATE TABLE 的 MySQL 存储过程?
若要在存储过程中执行 SHOW CREATE TABLE,使用 SHOW CREATE TABLE。我们首先创建一个表 -
mysql> create table DemoTable2011 -> ( -> StudentId int NOT NULL AUTO_INCREMENT, -> StudentName varchar(20), -> StudentAge int, -> StudentCountryName varchar(20), -> PRIMARY KEY(StudentId) -> ); Query OK, 0 rows affected (0.80 sec)
下面是执行 SHOW CREATE TABLE 的存储过程 -
mysql> delimiter // mysql> create procedure test_show_create_demo(table_name varchar(100)) -> begin -> set @query=concat("SHOW CREATE TABLE ",table_name); -> prepare st from @query; -> execute st; -> end -> // Query OK, 0 rows affected (0.22 sec) mysql> delimiter ;
使用 CALL 命令调用存储过程 -
mysql> call test_show_create_demo('DemoTable2011');
这将产生以下输出 -
+---------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Table | Create Table | +---------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | DemoTable2011 | CREATE TABLE `demotable2011` ( `StudentId` int(11) NOT NULL AUTO_INCREMENT, `StudentName` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL, `StudentAge` int(11) DEFAULT NULL, `StudentCountryName` varchar(20) COLLATE utf8_unicode_ci DEFAULT NULL, PRIMARY KEY (`StudentId`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci | +---------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 1 row in set (0.01 sec) Query OK, 0 rows affected, 1 warning (0.06 sec)
