通过搜索SQL Server中的所有表来查找字符串

有没有办法在SQL Server数据库的所有表中搜索字符串?

我想搜索字符串，比如john。结果应该显示包含john的表和它们各自的行。

改进来自@Brandon的惊人答案，我使用类型转换向ntext和xml添加了类型:

BEGIN TRAN

DECLARE @SearchStr nvarchar(100) = 'SEARCH_TEXT'
DECLARE @Results TABLE (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

SET NOCOUNT ON

DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
SET  @TableName = ''
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

WHILE @TableName IS NOT NULL

BEGIN
    SET @ColumnName = ''
    SET @TableName = 
    (
        SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
        FROM     INFORMATION_SCHEMA.TABLES
        WHERE         TABLE_TYPE = 'BASE TABLE'
            AND    QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
            AND    OBJECTPROPERTY(
                    OBJECT_ID(
                        QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
                         ), 'IsMSShipped'
                           ) = 0
    )

    WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)

    BEGIN
        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 IN ('char', 'varchar', 'nchar', 'nvarchar', 'int', 'decimal', 'ntext', 'xml')
                AND    QUOTENAME(COLUMN_NAME) > @ColumnName
        )

        IF @ColumnName IS NOT NULL

        BEGIN
            INSERT INTO @Results
            EXEC
            (
                'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT((cast(' + @ColumnName + ' as nvarchar(max))), 3630) 
                FROM ' + @TableName + ' (NOLOCK) ' +
                ' WHERE (cast(' + @ColumnName + ' as nvarchar(max))) LIKE ' + @SearchStr2
            )
        END
    END    
END

SELECT ColumnName, ColumnValue FROM @Results

ROLLBACK

有点晚了，但希望有用。

为什么不尝试一些可以集成到SSMS中的第三方工具呢?

我使用过ApexSQL Search(100%免费)，在模式和数据搜索方面都取得了很好的成功，还有SSMS工具包也有这个功能(SQL 2012不是免费的，但相当实惠)。

上面的存储过程真的很棒;只是在我看来这样更方便。此外，如果你想搜索datetime列或GUID列等，它将需要一些轻微的修改…

更新TechDo对SQL server 2012的答案。你需要更改:'FROM ' + @TableName + ' (NOLOCK)+ @TableName + 'WITH (NOLOCK)' +

在这个版本的SQL Server中不支持已弃用的功能“不带WITH的表提示”。

下面是更新后的完整存储过程:

    WHILE @TableName IS NOT NULL

    BEGIN

        SET @TableName = 
        (
            SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))

                             ), 'IsMSShipped'
                               ) = 0

不需要嵌套循环(遍历表的外部循环和遍历所有表列的内部循环)。可以从INFORMATION_SCHEMA中检索所有(或任意选择/筛选的)表-列组合。COLUMNS和在一个循环中简单地遍历(搜索)所有它们:

DECLARE @search VARCHAR(100), @table SYSNAME, @column SYSNAME

DECLARE curTabCol CURSOR FOR
    SELECT c.TABLE_SCHEMA + '.' + c.TABLE_NAME, c.COLUMN_NAME
    FROM INFORMATION_SCHEMA.COLUMNS c
    JOIN INFORMATION_SCHEMA.TABLES t 
      ON t.TABLE_NAME=c.TABLE_NAME AND t.TABLE_TYPE='BASE TABLE' -- avoid views
    WHERE c.DATA_TYPE IN ('varchar','nvarchar') -- searching only in these column types
    --AND c.COLUMN_NAME IN ('NAME','DESCRIPTION') -- searching only in these column names

SET @search='john'

OPEN curTabCol
FETCH NEXT FROM curTabCol INTO @table, @column

WHILE (@@FETCH_STATUS = 0)
BEGIN
    EXECUTE('IF EXISTS 
             (SELECT * FROM ' + @table + ' WHERE ' + @column + ' = ''' + @search + ''') 
             PRINT ''' + @table + '.' + @column + '''')
    FETCH NEXT FROM curTabCol INTO @table, @column
END

CLOSE curTabCol
DEALLOCATE curTabCol

如果您像我一样，在生产环境中有某些限制，那么您可能希望使用表变量而不是临时表，使用临时查询而不是创建过程。

当然，根据您的sql server实例，它必须支持表变量。

我还添加了一个USE语句来缩小搜索范围

USE DATABASE_NAME
DECLARE @SearchStr nvarchar(100) = 'SEARCH_TEXT'
DECLARE @Results TABLE (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

SET NOCOUNT ON

DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
SET  @TableName = ''
SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

WHILE @TableName IS NOT NULL

BEGIN
    SET @ColumnName = ''
    SET @TableName = 
    (
        SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
        FROM     INFORMATION_SCHEMA.TABLES
        WHERE         TABLE_TYPE = 'BASE TABLE'
            AND    QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
            AND    OBJECTPROPERTY(
                    OBJECT_ID(
                        QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
                         ), 'IsMSShipped'
                           ) = 0
    )

    WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)

    BEGIN
        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 IN ('char', 'varchar', 'nchar', 'nvarchar', 'int', 'decimal')
                AND    QUOTENAME(COLUMN_NAME) > @ColumnName
        )

        IF @ColumnName IS NOT NULL

        BEGIN
            INSERT INTO @Results
            EXEC
            (
                'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) 
                FROM ' + @TableName + ' (NOLOCK) ' +
                ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
            )
        END
    END    
END

SELECT ColumnName, ColumnValue FROM @Results
