我有几年前为类似目的而构建的这个脚本，尽管它带有文本字段。它找到符合条件的列，然后在这些列中搜索值。由于您的范围是不确定的，因此您可能无法比这样做得更好。
您可能需要稍微调整一下以包含唯一标识符列 - 如果这实际上是数据类型 - 或者使用相等而不是类似搜索。
如果这是您要定期重复使用的东西，您可以向它提供一个常用表或列的列表以在其中查找这些东西，这样就不会花很长时间找到东西。
/*This script will find any text value in the database*/
/*Output will be directed to the Messages window. Don't forget to look there!!!*/
SET NOCOUNT ON
DECLARE @valuetosearchfor varchar(128), @objectOwner varchar(64)

PRINT ''
DECLARE @iterator int, @sql varchar(4000)
SET @iterator = 1
WHILE @iterator <= (SELECT Max(id) FROM @potentialcolumns)

SET @sql = (SELECT [sql] FROM @potentialcolumns where [id] = @iterator)
IF (@sql IS NOT NULL) and (RTRIM(LTRIM(@sql)) <> '')
BEGIN

如果这看起来很奇怪，那么脚本正在执行这样的语句
if exists (select 1 from [schema].[table_name] (NOLOCK)
where [column_name] LIKE '%yourValue%')
begin
print select * from [schema].[table_name] (NOLOCK)
where [column_name] LIKE '%yourValue%'
end
...只需循环替换[schema]、[table_name]、[column_name] 和%yourValue%。
它的过滤...
- 特定架构中的表（可以删除过滤器）
- 只有表格，没有视图（可以调整）
- 仅包含搜索值的列
-
(n)char/(n)varchar/(n)text 数据类型（添加或更改，注意数据类型转换）
最后，输出不会进入结果网格。检查消息窗口（您会看到“N 行受影响”）
