python中sql语句多个 查询条件的怎么写
results=self.db.query('SELECTLP.IdLineProductId,LP.SupplierLineTitle,LP.MainTitle,LP....
results = self.db.query(
'SELECT LP.Id LineProductId,LP.SupplierLineTitle,LP.MainTitle,LP.SubTitle,LP.ShowTitle ,LPC.CityId DestinationCityId,\
LPC.CityName DestinationCityName,LP.Days,LP.DataFlag,LP.IfDel,LP.RecomImage_Ids AS LineProductRecomImage\
FROM [TCZiZhuYou].dbo.[ZZY_LineProduct] LP WITH(NOLOCK)\
INNER JOIN [TCZiZhuYou].dbo.[ZZY_LineProductCity] LPC WITH(NOLOCK) ON LPC.LineProduct_Id=LP.Id AND LPC.DataFlag=1 AND LPC.IsDestination=1 \
WHERE LP.Id=%d AND LP.LineProductType=%d ' % line_id % line_type )[0]
去掉一个就对了,但查询条件有两个,该怎么改 展开

python中有很多字符串连接方式,今天在写代码,顺便总结一下:
最原始的字符串连接方式:str1 + str2
python 新字符串连接语法:str1, str2
奇怪的字符串方式:str1 str2
% 连接字符串:‘name:%s; sex: ’ % ('tom', 'male')
字符串列表连接:str.join(some_list)
第四种功能比较强大,借鉴了C语言中 printf 函数的功能,如果你有C语言基础,看下文档就知道了。这种方式用符号“%”连接一个字符串和一组变量,字符串中的特殊标记会被自动用右边变量组中的变量替换。
试试这个
results = self.db.query(
'SELECT LP.Id LineProductId,LP.SupplierLineTitle,LP.MainTitle,LP.SubTitle,LP.ShowTitle ,LPC.CityId DestinationCityId,\
LPC.CityName DestinationCityName,LP.Days,LP.DataFlag,LP.IfDel,LP.RecomImage_Ids AS LineProductRecomImage\
FROM [TCZiZhuYou].dbo.[ZZY_LineProduct] LP WITH(NOLOCK)\
INNER JOIN [TCZiZhuYou].dbo.[ZZY_LineProductCity] LPC WITH(NOLOCK) ON LPC.LineProduct_Id=LP.Id AND LPC.DataFlag=1 AND LPC.IsDestination=1 \
WHERE LP.Id=%d AND LP.LineProductType=%d ' %( line_id, line_type) )[0]
