Sql server 2008 在SQLServer2008的dbMail中使用游标

我正在尝试将汇款信息发送给我们的客户，支票上有支票和金额。我无法向每位客户发送一封包含支票号码、金额和汇款信息的电子邮件

现在，电子邮件被生成，但它只选择一个客户，并发送与被提取的记录数相等的电子邮件。请看一看我下面的查询，可能我把光标部分搞乱了。 新代码 *旧代码***

我想你会想把你的电子邮件放在光标里——类似于

DECLARE @body nvarchar(max)
DECLARE EmailCursor CURSOR FOR 
  SELECT checknum, checkamt, email FROM .... -- one row per required email

OPEN EmailCursor
FETCH NEXT FROM EmailCursor INTO  @checknum, @checkAmt, @EMAIL
WHILE (@@FETCH_STATUS = 0)
BEGIN
  -- do the bit to build email in here 
  set @body = '<table>'
  select @body = @body + '<tr><td>' + docnum + '</td>'

-- .... rest of fields here
                       + '<td>'+ Cardcode +'</td></tr>'
  from -- .... 
  where checknum = @checknum -- or whatever gives this context
  set @body = @body + '</table>'

  exec  msdb.dbo.sp_send_dbmail -- ...

  FETCH NEXT FROM EmailCursor INTO  @checknum, @checkAmt, @EMAIL
end

伊恩，你的建议解决了一个问题，现在它是根据客户的支票号码和金额向客户发送电子邮件，但在汇款表中，它只选择最上面一行。对于汇款，我想显示用于切割特定支票的所有发票。我已经按照你的建议粘贴了新代码。非常感谢。伊恩，我已经根据你的建议粘贴了上面的代码。我看到了，看到了我在问题下的评论。我添加了新代码，但现在我收到了这个错误：Msg 245，16级，状态1，将nvarchar值转换为数据类型inti时，第32行转换失败。如果光标中的select语句可以返回多行，则需要使用我在回答中演示的方法来构建html表。按照您的操作方式，@docnum等变量只能设置为一行中的值。在我发布的答案中，它使用select中的实际字段来构建html字符串
