通过搜索SQL Server Management Studio 2008中的所有表来查找字符串

Question

有没有办法在SQL Server Management Studio 2008中的数据库的所有表中搜索字符串？

我想搜索字符串说john.结果应显示包含的表及其各自的行john.

Answer 1

如果您像我一样并且在生产环境中有某些限制,您可能希望使用表变量而不是临时表,以及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

Answer 2

有点晚,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.

我已经使用ApexSQL Search(100%免费)并且在模式和数据搜索方面取得了很大的成功,并且还有SSMS工具包具有此功能(对于SQL 2012不是免费的,但非常实惠).

上面的存储过程真的很棒; 这只是在我看来这更方便.此外,如果要搜索datetime列或GUID列等,则需要稍作修改......

Answer 3

更新TechDo对SQL Server 2012的回答.您需要更改:'FROM ' + @TableName + ' (NOLOCK) ' to FROM ' + @TableName + 'WITH (NOLOCK) ' +

另外,你会得到以下错误: Deprecated feature 'Table hint without WITH' is not supported in this version of SQL Server.

以下是完整的更新存储过程:

CREATE PROC SearchAllTables
(
@SearchStr nvarchar(100)
)
AS
BEGIN

    CREATE TABLE #Results (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

        )

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

        BEGIN
            SET @ColumnName =

有点晚了,但你可以很容易地找到这个查询的字符串

DECLARE
@search_string  VARCHAR(100),
@table_name     SYSNAME,
@table_id       INT,
@column_name    SYSNAME,
@sql_string     VARCHAR(2000)

SET @search_string = 'StringtoSearch'

DECLARE tables_cur CURSOR FOR SELECT ss.name +'.'+ so.name [name], object_id FROM sys.objects so INNER JOIN sys.schemas ss ON so.schema_id = ss.schema_id WHERE  type = 'U'

OPEN tables_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id

WHILE (@@FETCH_STATUS = 0)
BEGIN
    DECLARE columns_cur CURSOR FOR SELECT name FROM sys.columns WHERE object_id = @table_id 
        AND system_type_id IN (167, 175, 231, 239)

    OPEN columns_cur

    FETCH NEXT FROM columns_cur INTO @column_name
        WHILE (@@FETCH_STATUS = 0)
        BEGIN
            SET @sql_string = 'IF EXISTS (SELECT * FROM ' + @table_name + ' WHERE [' + @column_name + '] 
            LIKE ''%' + @search_string + '%'') PRINT ''' + @table_name + ', ' + @column_name + ''''

            EXECUTE(@sql_string)

        FETCH NEXT FROM columns_cur INTO @column_name
        END

    CLOSE columns_cur

DEALLOCATE columns_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id
END

CLOSE tables_cur
DEALLOCATE tables_cur

不需要嵌套循环（通过表的外部循环和通过所有表列的内部循环）。人们可以检索所有（或任意选择/过滤的）表列组合，INFORMATION_SCHEMA.COLUMNS并在一个循环中简单地传递（搜索）所有这些组合：

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

我为此编写了一个 SP，它以表名称、在其中找到搜索关键字字符串的列名称以及搜索相应的行的形式返回搜索结果，如下面的屏幕截图所示。

这可能不是最有效的解决方案，但您始终可以根据需要修改和使用它。

IF OBJECT_ID('sp_KeywordSearch', 'P') IS NOT NULL
    DROP PROC sp_KeywordSearch
GO

CREATE PROCEDURE sp_KeywordSearch @KeyWord NVARCHAR(100)
AS
BEGIN
    DECLARE @Result TABLE
        (TableName NVARCHAR(300),
         ColumnName NVARCHAR(MAX))

    DECLARE @Sql NVARCHAR(MAX),
        @TableName NVARCHAR(300),
        @ColumnName NVARCHAR(300),
        @Count INT

    DECLARE @tableCursor CURSOR

    SET @tableCursor = CURSOR LOCAL SCROLL FOR
    SELECT  N'SELECT @Count = COUNT(1) FROM [dbo].[' + T.TABLE_NAME + '] WITH (NOLOCK) WHERE CAST([' + C.COLUMN_NAME +
            '] AS NVARCHAR(MAX)) LIKE ''%' + @KeyWord + N'%''',
            T.TABLE_NAME,
            C.COLUMN_NAME
    FROM    INFORMATION_SCHEMA.TABLES AS T WITH (NOLOCK)
    INNER JOIN INFORMATION_SCHEMA.COLUMNS AS C WITH (NOLOCK)
    ON      T.TABLE_SCHEMA = C.TABLE_SCHEMA AND
            T.TABLE_NAME = C.TABLE_NAME
    WHERE   T.TABLE_TYPE = 'BASE TABLE' AND
            C.TABLE_SCHEMA = 'dbo' AND
            C.DATA_TYPE NOT IN ('image', 'timestamp')

    OPEN @tableCursor
    FETCH NEXT FROM @tableCursor INTO @Sql, @TableName, @ColumnName

    WHILE (@@FETCH_STATUS = 0)
    BEGIN
        SET @Count = 0

        EXEC sys.sp_executesql
            @Sql,
            N'@Count INT OUTPUT',
            @Count OUTPUT

        IF @Count > 0
        BEGIN
            INSERT  INTO @Result
                    (TableName, ColumnName)
            VALUES  (@TableName, @ColumnName)
        END

        FETCH NEXT FROM @tableCursor INTO @Sql, @TableName, @ColumnName
    END

    CLOSE @tableCursor
    DEALLOCATE @tableCursor

    SET @tableCursor = CURSOR LOCAL SCROLL FOR
    SELECT  SUBSTRING(TB.Sql, 1, LEN(TB.Sql) - 3) AS Sql, TB.TableName, SUBSTRING(TB.Columns, 1, LEN(TB.Columns) - 1) AS Columns
    FROM    (SELECT R.TableName, (SELECT R2.ColumnName + ', ' FROM @Result AS R2 WHERE R.TableName = R2.TableName FOR XML PATH('')) AS Columns,
                    'SELECT * FROM ' + R.TableName + ' WITH (NOLOCK) WHERE ' +
                    (SELECT 'CAST(' + R2.ColumnName + ' AS NVARCHAR(MAX)) LIKE ''%' + @KeyWord + '%'' OR '
                     FROM   @Result AS R2
                     WHERE  R.TableName = R2.TableName
                    FOR
                     XML PATH('')) AS Sql
             FROM   @Result AS R
             GROUP BY R.TableName) TB
    ORDER BY TB.Sql

    OPEN @tableCursor
    FETCH NEXT FROM @tableCursor INTO @Sql, @TableName, @ColumnName

    WHILE (@@FETCH_STATUS = 0)
    BEGIN
        PRINT @Sql
        SELECT  @TableName AS [Table],
                @ColumnName AS Columns
        EXEC(@Sql)

        FETCH NEXT FROM @tableCursor INTO @Sql, @TableName, @ColumnName
    END

    CLOSE @tableCursor
    DEALLOCATE @tableCursor

END
