场景描述:业务需要,客户要求。
上网搜了半天,只有连oracle或者mysql的,只能是借鉴一下看看能不能用了。
大多数文章上说要用JayDeBeApi 包
直接用
直接进cmd pip install JayDeBeApi
报错了,
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
解决办法
1. 安装 Microsoft visual c++ 14.0
https://964279924.ctfile.com/fs/1445568-239446865
安装完成之后再
pip install JayDeBeApi
样例代码如下:
根据网上其他人写的一些进行修改,主要是 jarFile ,链接oracle 只需要引入ojdbc的jar包就行了,hive这里需要使用列表,把所有相关的jar都放到jarFile中。
# Mike Sun import jaydebeapi url = 'jdbc:hive2:/127.0.0.1:10000/default' user = 'hive' password = 'hive' dirver = 'org.apache.hive.jdbc.HiveDriver' jarFile = [ 'D:\Maven\org\apache\hive\hive-jdbc\1.2.1\hive-jdbc-1.2.1.jar', 'D:\Maven\org\apache\hive\hive-exec\1.2.1\hive-exec-1.2.1.jar', 'D:\Maven\org\apache\hive\hive-metastore\1.2.1\hive-metastore-1.2.1.jar', 'D:\Maven\org\apache\hive\hive-service\1.2.1\hive-service-1.2.1.jar', 'D:\Maven\org\apache\hadoop\hadoop-common\2.7.4\hadoop-common-2.7.4.jar', 'D:\Maven\org\apache\thrift\libfb303\0.9.2\libfb303-0.9.2.jar', 'D:\Maven\commons-logging\commons-logging\1.2\commons-logging-1.2.jar','D:\Maven\org\slf4j\slf4j-api\1.7.25\slf4j-api-1.7.25.jar', 'D:\Maven\org\apache\httpcomponents\httpclient\4.5.5\httpclient-4.5.5.jar','D:\Maven\org\apache\httpcomponents\httpcore\4.4.9\httpcore-4.4.9.jar', 'D:\Maven\org\slf4j\slf4j-simple\1.7.25\slf4j-simple-1.7.25.jar'] sqlStr = 'select * from test_table' conn = jaydebeapi.connect(dirver, url, [user, password], jarFile) curs = conn.cursor() curs.execute(sqlStr) result = curs.fetchall() print(result) curs.close() conn.close()
