我有一栏载有页标题,其网站名称附在后面。 (例如,产品名称:UNV公司名称公司) 我愿同时从多个行文中删除“公司名称”。 SQl问询(或问询本身)将使我能够做到这一点?

To re-illustrate, I want to convert multiple rows of 1 column from this: Product Name | Company Name Inc.

To this: Product Name

问题回答

你指的是(在服务器中):

Update Table
Set PageTitle = Substring( PageTitle, 1, CharIndex(  | , PageTitle ) - 1)

基本上,Im利用CharIndex找到划界员( ́ >),然后利用Substring在划界者面前寻找一切。

In MySql 我认为,这符合以下原则:

Update Table
Set PageTitle = Substring( PageTitle, 1, Substring_Index(PageTitle,  |  ) - 1)
