更新和替换多个字段，但在每个语句后收到错误

Question

我正在更新多个字段，我的查询正确地处理每个语句但是当它转到下一行时出错。我注释掉前面的行并重新运行并在下一行运行语句和错误 即

UPDATE mydb
    SET VendorMPD = replace(VendorMPD,'VENDOR Campaign MPD - ','');
    SET VendorMPDHalf = replace(VendorMPDHalf,'Vendor MPD 1/2 Count - ','');
    SET DieselMPD = replace(DieselMPD,'Diesel Pumps - ','')

每次生成时出错：

[Err] 42000 - [SQL Server]Incorrect syntax near '='.

我昨天完成了这项工作，但需要添加额外的字段，当我这样做时，这就是开始发生的事情。我查看了我输入的新语句，除了字段名称和它们正在替换的内容。编码是相同的。

尝试使用以下语法在单个语句中更新多个列：

UPDATE mydb
SET VendorMPD = replace(VendorMPD,'VENDOR Campaign MPD - ',''),
    VendorMPDHalf = replace(VendorMPDHalf,'Vendor MPD 1/2 Count - ',''),
    DieselMPD = replace(DieselMPD,'Diesel Pumps - ','');
