如何使用 Python 获取结果集


cursor 方法用于在打开的连接上创建游标。execute 方法用于创建结果集。fetchall 方法用于获取此结果集中的行。

import sqlanydb

# Create a connection object, then use it to create a cursor
con = sqlanydb.connect( userid="DBA", 
                        password="sql" )
cursor = con.cursor()

# Execute a SQL string
sql = "SELECT * FROM Employees"

# Get a cursor description which contains column names
desc = cursor.description
print len(desc)

# Fetch all results from the cursor into a sequence, 
# display the values as column name=value pairs,
# and then close the connection
rowset = cursor.fetchall()
for row in rowset:
    for col in range(len(desc)):
        print "%s=%s" % (desc[col][0], row[col] )
