如何删除以下sql中的重复结果？

SELECT    * 
FROM      fccestimatedcustomer LEFT JOIN fcccustomerregistration 
ON        fccestimatedcustomer.CustomerRegistrationRefID = 
          fcccustomerregistration.CustomerRegistrationRefID
WHERE     fccestimatedcustomer.Status = 1 
ORDER BY  VehicleNumber ASC;

Answer 1

SELECT DISTINCT * 
FROM      fccestimatedcustomer LEFT JOIN fcccustomerregistration 
ON        fccestimatedcustomer.CustomerRegistrationRefID = 
          fcccustomerregistration.CustomerRegistrationRefID
WHERE     fccestimatedcustomer.Status = 1 
ORDER BY  VehicleNumber ASC;

试试这个。如果不行，请发布你的fccestimatedcustomer，fcccustomerregistration表的一些示例数据

最简单的方法是将DISTINCT与您希望进行此选择的指定字段一起使用。
