下載解壓縮后放到%Python_HOME%\Lib\site-packages目錄中，python會自動找到此包。 MySQLdb基本上是MySQL C API的Python版，遵循Python Database API Specification v2.0。 其他：
1. 平臺及版本
linux 內(nèi)核2.6，gcc 3.4.4，glibc 2.4 python 2.4.3 mysql 5.0.19 mysql-python 1.2.1-p2 2. 安裝mysql-python tar xvfz MySQL-python-1.2.1_p2.tar.gz cd MySQL-python-1.2.1_p2 python setup.py build python setup.py install 3. 使用
import MySQLdb 3.1. 連接 conn = MySQLdb.Connection(host, user, password, dbname) 3.2. 選擇數(shù)據(jù)庫 conn.select_db(’database name’) 3.3. 獲得cursor cur = conn.cursor() 3.4. cursor位置設(shè)定 cur.scroll(int, mode) mode可為相對位置或者絕對位置，分別為relative和absolute。 3.5. select cur.execute(‘select clause’) 例如 cur.execute(‘select * from mytable’) row = cur.fetchall() 或者： row1 = cur.fetchone() 3.6. insert cur.execute(‘inset clause’) 例如 cur.execute(‘insert into table (row1, row2) values (\’111\’, \’222\’)’) conn.commit()
3.7. update
cur.execute(‘update clause’) 例如 cur.execute(“update table set row1 = ‘’ where row2 = ‘row2 ‘ ”) conn.commit()
3.8. delete cur.execute(‘delete clause’) 例如 cur.execute(“delete from table where row1 = ‘row1’ ”) conn.commit() 本文來自CSDN博客，轉(zhuǎn)載請標(biāo)明出處：http://blog.csdn.net/wenhai_zhang/archive/2009/12/14/5006526.aspx
