传说中的MySQL 5 具有了存储过程的功能,今天小试一把.哈,还真不错 :)
写下来,和大家一起学习.以后的一些高级功能,偶有空就写写,接着续在整个
帖子下面. ok,开始......
1、下载、安装,不用多说(偶喜欢非安装版,解压就能用,方便)
2、启动MySQL 5 :
开启一个控制台,并进入到MySQL 的 bin目录下;
登录,输入: mysql -h localhost -u root -p
3、选择一个数据库: 偶使用test整个数据库。这个库没有任何的表。
4、建立一个表:
mysql> CREATE TABLE pet (name VARCHAR(20), owner VARCHAR(20),
-> species VARCHAR(20), sex CHAR(1), birth DATE, death DATE);
5、插入一行数据:
mysql> INSERT INTO pet
-> VALUES (′Puffball′,′Diane′,′hamster′,′f′,′1999-03-30′,NULL);
6、创建一个过程:
mysql> delimiter // --- 这是定义结束符为“//”
mysql> CREATE PROCEDURE simpleproc (OUT param1 INT)
-> BEGIN
-> SELECT COUNT(*) INTO param1 FROM t;
-> END
-> //
Query OK, 0 rows affected (0.00 sec)
好,一个过程创建完毕。
7、执行过程:
mysql> delimiter ; --- 这是定义结束符为“;”,因为上面定义成了“//”,要改回来,保持习惯一致。
mysql> CALL simpleproc(@a);
Query OK, 0 rows affected (0.00 sec)
mysql> SELECT @a;
+------+
| @a |
+------+
| 3 |
+------+
1 row in set (0.00 sec)
哈哈,过程调用成功。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
