我正在寻找一个数值= 6.84 -使用这里的其他答案，我能够将我的搜索限制在这个范围内

Declare @sourceTable Table(id INT NOT NULL IDENTITY PRIMARY KEY, table_name varchar(1000), column_name varchar(1000))
Declare @resultsTable Table(id INT NOT NULL IDENTITY PRIMARY KEY, table_name varchar(1000))

Insert into @sourceTable(table_name, column_name)
select schema_name(t.schema_id) + '.' + t.name as[table], c.name as column_name
from sys.columns c
join sys.tables t
on t.object_id = c.object_id
where type_name(user_type_id) in ('decimal', 'numeric', 'smallmoney', 'money', 'float', 'real')
order by[table], c.column_id;

DECLARE db_cursor CURSOR FOR
Select table_name, column_name from @sourceTable
DECLARE @mytablename VARCHAR(1000);
DECLARE @mycolumnname VARCHAR(1000);

OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @mytablename, @mycolumnname

WHILE @ @FETCH_STATUS = 0
BEGIN
    Insert into @ResultsTable(table_name)
    EXEC('SELECT ''' + @mytablename + '.' + @mycolumnname + '''  FROM ' + @mytablename + ' (NOLOCK) ' +
    ' WHERE ' + @mycolumnname + '=6.84')
    FETCH NEXT FROM db_cursor INTO @mytablename, @mycolumnname  
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;
Select Distinct(table_name) from @ResultsTable

这是我解决这个问题的方法。在SQLServer2008R2上测试

这是我对这个问题的独立看法，我用在我自己的工作中。它可以在SQL2000及更高版本中工作，允许通配符、列过滤，并搜索大多数常规数据类型。

我没有把它放在proc形式中，因为我不想在数百个db中维护它，而且它实际上是用于临时工作的。请随意评论错误修复。

到目前为止，我发现的最好和最通用的解决方案是通过管道将db的转储传递给您正在搜索的grep。

例如，Mysql:

mysqldump -pPASSWORD database | grep 'search phrase'

或者如果你得到了太多的结果，你可以把它们输出到一个文件:

mysqldump -pPASSWORD database | grep 'search phrase' > results.txt

我优化了Allain Lalonde的答案(https://stackoverflow.com/a/436676/412368)。 仍然支持数值。应该大约快4-5倍(1:03 vs 4:30)，在带有7GB数据库的桌面上测试。http://developer.azurewebsites.net/2015/01/mssql-searchalltables/
