Re: Pyflink1.12尝试连接oracle数据，报错findAndCreateTableSource failed

2020-12-16 文章 Dian Fu 
看起来是jar的路径的问题，你需要看一下在windows上，jar的路径用URL表示应该是什么样的。另外也可以直接把jar包放到pyflink安装目录中的lib目录下。

 1）如Leonard Xu老师所说，目前JDBC connector还不支持oracle
 2）从报错看，你这还都没有走到那一步就报错了，可以检查一下这些：
   a. JDBC connector的使用方式参考[1]，比如'connector' = 'jdbc'，而不是'connector.type' = 
 'jdbc'，这个是老的使用方式
   b. JDBC 
 connector的jar需要显式添加相关依赖，可以如何在PyFlink中添加jar依赖，可以看一下[2]。其中JDBC需要的的jar，可以参考[1]

Re: Pyflink1.12尝试连接oracle数据，报错findAndCreateTableSource failed

2020-12-16 文章 Dian Fu 
1）如Leonard Xu老师所说，目前JDBC connector还不支持oracle
2）从报错看，你这还都没有走到那一步就报错了，可以检查一下这些：
 a. JDBC connector的使用方式参考[1]，比如'connector' = 'jdbc'，而不是'connector.type' = 
'jdbc'，这个是老的使用方式
 b. JDBC 
connector的jar需要显式添加相关依赖，可以如何在PyFlink中添加jar依赖，可以看一下[2]。其中JDBC需要的的jar，可以参考[1]
