以下是一个使用pyodbc连接 SQL Server 并执行存储过程的示例代码: 示例代码 importpyodbcdefexecute_stored_procedures(connection_string):# 创建数据库连接conn=pyodbc.connect(connection_string)cursor=conn.cursor()# 查询所有存储过程cursor.execute("SELECT procedure_name, parameters FROM stored_procedures")procedures...
SQL Server支持存储过程的执行,我们可以使用Python来调用SQL Server中的存储过程: cursor.execute("{CALL stored_procedure_name (?, ?)}",(param1,param2))conn.commit() 1. 2. 这将调用名为stored_procedure_name的存储过程,并传递param1和param2作为参数。 事务控制 在处理数据时,有时候需要确保一组操作要...

问题1:存储过程执行失败,报错“Procedure does not exist” 原因: 存储过程名称拼写错误。 存储过程所在的数据库或模式不正确。 解决方法: 确认存储过程名称拼写正确。 使用cur.execute("SELECT * FROM information_schema.routines WHERE routine_name = 'your_stored_procedure';")检查存储过程是否存在。 问题2:参数...

When you run Python "inside" SQL Server, you must encapsulate the Python script inside a special stored procedure, sp_execute_external_script.After the script has been embedded in the stored procedure, any application that can make a stored procedure call can initiate execution of the Python ...
