我有两张桌子..

人：

  empid(primary key)
  firstname
  lastname
  email

详细说明：

  Did(primary key)
  salary
  designation
  empid

现在我需要更新姓名为＆＃39; abc＆＃39;的员工的电子邮件。 AND指定为经理。（假设有多个员工姓名abc，因此需要检查指定）我正在使用sql server 2008

Answer 1

UPDATE p
  SET email = 'newemail@wherever.com'
  FROM dbo.Persons AS p
  INNER JOIN dbo.Details AS d
  ON p.empid = d.empid
  WHERE p.firstname = 'abc'
  AND d.Designation = 'manager';

Answer 2

试试这个：

UPDATE 
  [Persons] 
SET 
  [Persons].[email]='###@###.###'
FROM 
  [Persons] 
  INNER JOIN [Persons].[empid] 
  ON [Details].[empid] = [Persons].[empid] 
WHERE 
  [Persons].[firstname]='abc' AND 
  [Details].[designation]='Manager'
