Question

我正在尝试执行以下声明：

  update dbo.CaseTable
  set Quick=REPLACE(Quick, 
    "Case files have been archived.  To have file access restored, please enter a helpdesk ticket with the full case name.  Case files have been archived.  To have file access restored, please enter a helpdesk ticket with the full case name.", 
    "Case files have been archived.  To have file access restored, please enter a helpdesk ticket with the full case name.")

我收到以下错误：

Msg 103，Level 15，State 4，Line 2 以＆＃39; Case文件开头的标识符已存档。要恢复文件访问权限，请输入包含完整案例名称的帮助台票证。案例档案＆＃39;太长。最大长度为128。

如果这个字符串太长，怎么能替换它？

Answer 1

您已使用双引号作为替换字符串，请使用单引号。下面的查询应该工作正常。基本上，双引号内提供的文本被视为列名。

set Quick=REPLACE(Quick, 'Case files have been archived. To have file access        restored, please enter a helpdesk ticket with the full case name. Case files have been archived. To have file access restored, please enter a helpdesk ticket with the full case name.', 'Case files have been archived. To have file access restored, please enter a helpdesk ticket with the full case name.')

由于sql不允许替换ntext类型，请使用以下查询。

Quick = CAST(REPLACE(CAST(Quick as NVarchar(MAX)), 'Case files have been archived. To have file access restored, please enter a helpdesk ticket with the full case name. Case files have been archived. To have file access restored, please enter a helpdesk ticket with the full case name.', 'Case files have been archived. To have file access restored, please enter a helpdesk ticket with the full case name.') AS NText)
