Now that you've wrapped the Python function in a stored procedure, you can easily call the function and pass in different values, like this:SQL Copy EXECUTE MyPyNorm @param1 = 100,@param2 = 50, @param3 = 3 Use Python utility functions for troubleshooting...
//其中第一个参数类型为IN,后续所有参数都为OUT,典型的复杂查询型存储过程CALLYourStoreProcedure("yourParama",@out_1,@out_2,@out_3,@out_4,@out_5,@out_6);SELECT@out_1,@out_2,@out_3,@out_4,@out_5,@out_6 结果是不行,会报错,具体的报错我就没有分析了,大家可以自行尝试。
