Question

我有一个代码可以将查询结果保存到csv文件中。是否可以根据查询结果制作条件？例如：

如果查询结果包含字符串“Test”，则执行另一个查询并将其保存到现有文件。

我应该使用“fetchone”方法吗？

我的代码：

try:
    connection = cx_Oracle.connect('TAGATE','TAGATE','GPSPL')
    cursor = connection.cursor()
    print "connected"

    try:

        query = """select example1 , example 2 from dbo1""".format(line_name)
        tmp = cursor.execute(query)
        columns = [i[0] for i in cursor.description]
        results = tmp.fetchall()

        cursor.close()

    except:
        pass


except:
    print IOError

filename='{0}.csv'.format(line_name)
if results:
    csv_file = open(filename,'wb')
    myFile = csv.writer(csv_file)
    myFile.writerow(columns)
    myFile.writerows(results)
#i think another statment should be here

Answer 1

我会做以下事情：

...
if results:
    for ex1, ex2 in results:
        # I assumed string was to be found in field 'Example1'
        if 'Test' in ex1:
            # Save your results as you do with csv_file = open(filename,'wb') and so on

Python - 基于查询结果的条件
