三列,自动增长id，name，以及datetime
mysql CREATE TABLE test123 (
- `id` INT AUTO_INCREMENT PRIMARY KEY,
- `name` VARCHAR(10),
- `datetime` DATETIME
- );
Query OK, 0 rows affected (0.06 sec)
插入数据
mysql INSERT INTO test123 (`name`, `datetime`)
- VALUES('Hello', '2011-04-22 21:18:00');
Query OK, 1 row affected (0.03 sec)
查询结果
mysql select * from test123;
+----+-------+---------------------+
| id | name | datetime |
+----+-------+---------------------+
| 1 | Hello | 2011-04-22 21:18:00 |
+----+-------+---------------------+
1 row in set (0.02 sec)
CREATE DEFINER = CURRENT_USER PROCEDURE `NewProc`(IN `username` varchar,IN `passwords` varchar)
BEGIN
INSERT INTO test_user (Username,Passwords) VALUES (username, passwords);
END;
以下只是个例子
CREATE procedure test
@n1 char(10),
@n2 char(10),
@n3 char(10),
@n4 char(10),
@n5 char(10),
@n6 char(10),
@n7 char(10),
@n8 datetime,
@n9 datetime,
@n10 int
as
select * --------这部分请将传入的参数带入查询的条件中
from table1 t1,table2 t2,table3 t3
where deldate between @n8 and @n9
and t1.ponum = t2.ponum
and t2.partnum = t3.partnum
and t3.layer =@n1
GO
CREATE FUNCTION `fristPinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
BEGIN
DECLARE V_RETURN VARCHAR(255);
SET V_RETURN = ELT(INTERVAL(CONV(HEX(left(CONVERT(P_NAME USING gbk),1)),16,10),
0xB0A1,0xB0C5,0xB2C1,0xB4EE,0xB6EA,0xB7A2,0xB8C1,0xB9FE,0xBBF7,
0xBFA6,0xC0AC,0xC2E8,0xC4C3,0xC5B6,0xC5BE,0xC6DA,0xC8BB,
0xC8F6,0xCBFA,0xCDDA,0xCEF4,0xD1B9,0xD4D1),
'A','B','C','D','E','F','G','H','J','K','L','M','N','O','P','Q','R','S','T','W','X','Y','Z');
RETURN V_RETURN;
END
pinyin ：此函数是将一个中文字符串对应拼音母的每个相连 (例如："中国人"-ZGR)
复制代码 代码如下:
CREATE FUNCTION `pinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
BEGIN
DECLARE V_COMPARE VARCHAR(255);
DECLARE V_RETURN VARCHAR(255);
DECLARE I INT;
SET I = 1;
SET V_RETURN = '';
while I LENGTH(P_NAME) do
SET V_COMPARE = SUBSTR(P_NAME, I, 1);
IF (V_COMPARE != '') THEN
#SET V_RETURN = CONCAT(V_RETURN, ',', V_COMPARE);
SET V_RETURN = CONCAT(V_RETURN, fristPinyin(V_COMPARE));
#SET V_RETURN = fristPinyin(V_COMPARE);
END IF;
SET I = I + 1;
end while;
IF (ISNULL(V_RETURN) or V_RETURN = '') THEN
SET V_RETURN = P_NAME;
END IF;
RETURN V_RETURN;
END
示例：
复制代码 代码如下:
mysql select p.province, fristPinyin(p.province), pinyin(p.province) from province p;
+------------------+-------------------------+--------------------+
| province | fristPinyin(p.province) | pinyin(p.province) |
+------------------+-------------------------+--------------------+

| 天津市 | T | TJS |
| 河北省 | H | HBS |
