python安裝DB2模塊

PyDB2最新的更新是2008的PyDB2_1.1.1，在ubuntu14.0464位下直接安裝不成功。須要作一些修改

1、解壓後打開setup.py

      找到#DB2_ROOT = "/opt/IBM/db2/V8.1/"

改成DB2_ROOT = "/opt/ibm/db2/V11.1/"（實際的安裝路徑）

2、仍是在setup.py下

找到    for path in ['lib','lib32', 'lib64']:

 改成   for path in ['lib64','lib32', 'lib']:

3、安裝PyDB2模塊

即：python setup.py build

sudo python setup.py install

4、測試

$ python

>>> import DB2

>>> conn = DB2.connect(dsn='sample',uid='db2inst1', pwd='you_passwd')

若是沒有錯誤信息、說明安裝成功了

代碼：

​
#coding=utf-8
import DB2

try:
    conn = DB2.connect(dsn='you-db', uid='username', pwd='passwd')
    cur = conn.cursor() 			
    cur.execute("SELECT * FROM you-table")
    data = cur.fetchall()
    for row in data:
        for col in row:
           print col,
           #print (col, end=' ')
        print#()
except DB2.Error as e:
    print ("Error %d: %s" % (e.args[0],e.args[1]))
finally:
    if conn:
        conn.close()

sudo pip install ibm_db

代碼：

#coding=utf-8
import ibm_db

conn = ibm_db.connect('you-db', 'user', 'passwd')
if conn:
    stmt = ibm_db.exec_immediate(conn, "SELECT * FROM MyTable")
    i = 0

    cols = ibm_db.fetch_tuple(stmt)
    while (cols):
        print "%s %s %s %s %s" % (cols[0], cols[1])
        i += 1
        cols = ibm_db.fetch_tuple(stmt)

    print "\nNumber of rows: %d" % i
else:
    print "Connection failed."
