给定一个数字,我如何发现在什么表和列中可以找到它?
我不在乎速度快不快,只要管用就行。

当前回答
假设您想要获取数据库中所有具有名称的表,列名包含logintime,下面的MyDatabase是代码示例
use MyDatabase
SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%logintime%'
ORDER BY schema_name, table_name;
其他回答
我之前有一个解决方案,我一直在改进。如果被告知在XML列中搜索,或者如果只提供整数字符串则搜索整数值。

这是我解决这个问题的方法。在SQLServer2008R2上测试
CREATE PROC SearchAllTables
@SearchStr nvarchar(100)
AS
BEGIN
DECLARE @dml nvarchar(max) = N''
IF OBJECT_ID('tempdb.dbo.#Results') IS NOT NULL DROP TABLE dbo.#Results
CREATE TABLE dbo.#Results
([tablename] nvarchar(100),
[ColumnName] nvarchar(100),
[Value] nvarchar(max))
SELECT @dml += ' SELECT ''' + s.name + '.' + t.name + ''' AS [tablename], ''' +
c.name + ''' AS [ColumnName], CAST(' + QUOTENAME(c.name) +
' AS nvarchar(max)) AS [Value] FROM ' + QUOTENAME(s.name) + '.' + QUOTENAME(t.name) +
' (NOLOCK) WHERE CAST(' + QUOTENAME(c.name) + ' AS nvarchar(max)) LIKE ' + '''%' + @SearchStr + '%'''
FROM sys.schemas s JOIN sys.tables t ON s.schema_id = t.schema_id
JOIN sys.columns c ON t.object_id = c.object_id
JOIN sys.types ty ON c.system_type_id = ty.system_type_id AND c .user_type_id = ty .user_type_id
WHERE t.is_ms_shipped = 0 AND ty.name NOT IN ('timestamp', 'image', 'sql_variant')
INSERT dbo.#Results
EXEC sp_executesql @dml
SELECT *
FROM dbo.#Results
END
非常感谢这个有用的脚本。
如果你的表有不可转换的字段,你可能需要在代码中添加以下修改:
SET @ColumnName =
(
SELECT MIN(QUOTENAME(COLUMN_NAME))
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = PARSENAME(@TableName, 2)
AND TABLE_NAME = PARSENAME(@TableName, 1)
AND DATA_TYPE NOT IN ('text', 'image', 'ntext')
AND QUOTENAME(COLUMN_NAME) > @ColumnName
)

如果你安装了phpMyAdmin,使用它的搜索功能。
选择您的数据库。
请确保您选择的是DataBase,而不是表,否则您将得到一个完全不同的搜索对话框。
单击“搜索”页签 列表项选择所需的搜索词 选择要搜索的表
如果您只需要运行一次这样的搜索,那么您可能可以使用其他答案中已经显示的任何脚本。但除此之外,我建议使用ApexSQL搜索。这是一个免费的SSMS插件,它真的为我节省了很多时间。
在运行任何脚本之前,您都应该根据要搜索的数据类型自定义脚本。如果你知道你正在搜索datetime列,那么就没有必要通过nvarchar列进行搜索。这将加快上面所有查询的速度。
