搜索特定值 SQL Server 的所有表、所有列 [英] Search all tables, all columns for a specific value SQL Server

问题描述

我有一个特定的值，比如说字符串评论".我需要在数据库中找到所有这样的实例，因为我需要更新格式以将其更改为 (*) 注释.

I have a specific value, let's say string 'comments'. I need to find all instances of this in the database as I need to do an update on the format to change it to (*) Comments.

我该怎么做?数据库采用 SQL Server 2000 格式.

How can I do this? The database is in SQL Server 2000 format.

推荐答案

我刚刚更新了我的博客文章以更正您使用 Jeff 的脚本中的错误，您可以在此处查看更新后的脚本:搜索 SQL Server 数据库中的所有字段

I've just updated my blog post to correct the error in the script that you were having Jeff, you can see the updated script here: Search all fields in SQL Server Database

根据要求，这里是脚本，以防您需要它，但我建议您查看博客文章，因为我会不时更新它

As requested, here's the script in case you want it but I'd recommend reviewing the blog post as I do update it from time to time

DECLARE @SearchStr nvarchar(100)
SET @SearchStr = '## YOUR STRING HERE ##'
