SQL Server 在指定数据库的所有表的所有列中搜索给定的值

这篇文章主要为大家详细介绍了SQL Server 在指定数据库的所有表的所有列中搜索给定的值，具有一定的参考价值，可以用来参考一下。

对此感兴趣的朋友，看看idc笔记做的技术笔记！

代码如下:

 
USE [NORTHWIND] 
GO 
/****** Object: StoredProcedure [dbo].[My_Search_StringInGivenTable] Script Date: 09/25/2011 15:37:14 ******/ 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 
CREATE PROCEDURE [dbo].[My_Search_StringInGivenTable] 
(@SearchString NVARCHAR(MAX), 
@Table_Schema sysname, 
@Table_Name sysname) 
AS 
BEGIN 
DECLARE @Columns NVARCHAR(MAX), @Cols NVARCHAR(MAX), @PkColumn NVARCHAR(MAX) 
-- Get all character columns 
SET @Columns = STUFF((SELECT ', ' + QUOTENAME(Column_Name) 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE DATA_TYPE IN ('text','ntext','varchar','nvarchar','char','nchar') 
AND TABLE_NAME = @Table_Name 
ORDER BY COLUMN_NAME 
FOR XML PATH('')),1,2,'') 
IF @Columns IS NULL -- no character columns 
RETURN -1 
-- Get columns for select statement - we need to convert all columns to nvarchar(max) 
SET @Cols = STUFF((SELECT ', cast(' + QUOTENAME(Column_Name) + ' as nvarchar(max)) as ' + QUOTENAME(Column_Name) 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE DATA_TYPE IN ('text','ntext','varchar','nvarchar','char','nchar') 
AND TABLE_NAME = @Table_Name 
ORDER BY COLUMN_NAME 
FOR XML PATH('')),1,2,'') 
SET @PkColumn = STUFF((SELECT N' + ''|'' + ' + ' cast(' + QUOTENAME(CU.COLUMN_NAME) + ' as nvarchar(max))' 
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS TC 
INNER JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE CU ON TC.TABLE_NAME = CU.TABLE_NAME 
AND TC.TABLE_SCHEMA = CU.TABLE_SCHEMA 
AND Tc.CONSTRAINT_NAME = CU.CONSTRAINT_NAME 
WHERE TC.CONSTRAINT_TYPE ='PRIMARY KEY' AND TC.TABLE_SCHEMA = @Table_Schema AND TC.TABLE_NAME = @Table_Name 
ORDER BY CU.COLUMN_NAME 
FOR XML PATH('')),1,9,'') 
IF @PkColumn IS NULL 
SELECT @PkColumn = 'cast(NULL as nvarchar(max))' 
-- set select statement using dynamic UNPIVOT 
DECLARE @SQL NVARCHAR(MAX) 
SET @SQL = 'select *, ' + QUOTENAME(@Table_Schema,'''') + 'as [Table Schema], ' + QUOTENAME(@Table_Name,'''') + ' as [Table Name]' +

WHERE [Column Value] LIKE ''%'' + @SearchString + ''%''' 
--print @SQL 
EXECUTE sp_ExecuteSQL @SQL, N'@SearchString nvarchar(max)', @SearchString 
END 

代码如下:

 
USE [NORTHWIND] 
GO 
/****** Object: StoredProcedure [dbo].[My_Search_String_AllTables] Script Date: 09/25/2011 15:41:58 ******/ 
SET ANSI_NULLS OFF 
GO 
SET QUOTED_IDENTIFIER OFF 
GO 
CREATE PROC [dbo].[My_Search_String_AllTables] 
( 
@SearchString NVARCHAR(MAX) 
) 
AS 
BEGIN 
CREATE TABLE #RESULT ([PK COLUMN] NVARCHAR(MAX), [COLUMN VALUE] NVARCHAR(MAX), [COLUMN Name] sysname, 
[TABLE SCHEMA] sysname, [TABLE Name] sysname) 
DECLARE @Table_Name sysname, @Table_Schema sysname 
DECLARE curAllTables CURSOR LOCAL FORWARD_ONLY STATIC READ_ONLY 
FOR 
SELECT Table_Schema, Table_Name 
FROM INFORMATION_SCHEMA.Tables 
WHERE TABLE_TYPE = 'BASE TABLE' 
ORDER BY Table_Schema, Table_Name 
OPEN curAllTables 
FETCH curAllTables 
INTO @Table_Schema, @Table_Name 
WHILE (@@FETCH_STATUS = 0) -- Loop through all tables in the database 
BEGIN 
INSERT #RESULT 
EXECUTE My_Search_StringInGivenTable @SearchString, @Table_Schema, @Table_Name 
FETCH curAllTables 
INTO @Table_Schema, @Table_Name 
END -- while 
CLOSE curAllTables 
DEALLOCATE curAllTables 
-- Return results 
SELECT * FROM #RESULT ORDER BY [Table Name] 
END 

代码如下:

 
USE [NORTHWIND] 
GO 
DECLARE @return_value int 
EXEC @return_value = [dbo].[My_Search_String_AllTables] 
@SearchString = N'WantValue' 
SELECT 'Return Value' = @return_value 
GO 

代码如下:

 
USE [NORTHWIND] 
GO 
/****** Object: StoredProcedure [dbo].[ZL_SearchAllTables] Script Date: 09/25/2011 15:44:10 ******/ 
SET ANSI_NULLS OFF 
GO 
SET QUOTED_IDENTIFIER OFF 
GO 
CREATE PROC [dbo].[ZL_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 + '%','''')

) 
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 
END 
[code] 
二、搜索数据是Int类型 
适用于搜索smallint, tinyint, int, bigint等类型 
1、创建存储过程 My_Search_IntInGivenTable 
[code] 
USE [NORTHWIND] 
GO 
/****** Object: StoredProcedure [dbo].[My_Search_IntInGivenTable] Script Date: 09/25/2011 15:45:46 ******/ 
SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 
CREATE PROCEDURE [dbo].[My_Search_IntInGivenTable] 
(@SearchValue INT, 
@Table_Schema sysname, 
@Table_Name sysname) 
AS 
BEGIN 
DECLARE @Columns NVARCHAR(MAX) , 
@Cols NVARCHAR(MAX) , 
@PkColumn NVARCHAR(MAX) , 
@SQL NVARCHAR(MAX) 
--判断并创建#Result表 
IF OBJECT_ID('TempDB..#Result', 'U') IS NOT NULL 
DROP TABLE #Result 
CREATE TABLE #RESULT 
( 
[PK COLUMN] NVARCHAR(MAX) , 
[COLUMN VALUE] BIGINT , 
[COLUMN Name] SYSNAME , 
[TABLE SCHEMA] SYSNAME , 
[TABLE Name] SYSNAME 
) 
--开始搜索给定的表 
DECLARE curAllTables CURSOR LOCAL FORWARD_ONLY STATIC READ_ONLY 
FOR 
SELECT Table_Schema , 
Table_Name 
FROM INFORMATION_SCHEMA.Tables 
WHERE Table_Name =@Table_Name 
OPEN curAllTables 
WHILE 1 = 1 
BEGIN 
FETCH curAllTables 
INTO @Table_Schema, @Table_Name 
IF @@FETCH_STATUS <> 0 -- Loop through all tables in the database 
BREAK 
PRINT CHAR(13) + 'Processing ' + QUOTENAME(@Table_Schema) + '.' 
+ QUOTENAME(@Table_Name) 
-- Get all int columns 
SET @Columns = STUFF(( SELECT ', ' + QUOTENAME(Column_Name) 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE DATA_TYPE LIKE '%int' 
AND TABLE_NAME = @Table_Name 
AND table_schema = @Table_Schema 
ORDER BY COLUMN_NAME 
FOR 
XML PATH('') 
), 1, 2, '') 
IF @Columns IS NULL 
BEGIN 
PRINT 'No int columns in the ' + QUOTENAME(@Table_Schema) 
+ '.' + QUOTENAME(@Table_Name) 
CONTINUE 
END 
-- Get columns for select statement - we need to convert all columns to bigint 
SET @Cols = STUFF(( SELECT ', cast(' + QUOTENAME(Column_Name) 
+ ' as bigint) as ' 
+ QUOTENAME(Column_Name) 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE DATA_TYPE LIKE '%int' 
AND TABLE_NAME = @Table_Name 
ORDER BY COLUMN_NAME 
FOR 
XML PATH('') 
), 1, 2, '') 
-- Create PK column(s) 
SET @PkColumn = STUFF(( SELECT N' + ''|'' + ' + ' cast(' 
+ QUOTENAME(CU.COLUMN_NAME) 
+ ' as nvarchar(max))' 
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS TC 
INNER JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE CU ON TC.TABLE_NAME = CU.TABLE_NAME 
AND TC.TABLE_SCHEMA = CU.TABLE_SCHEMA 
AND Tc.CONSTRAINT_NAME = CU.CONSTRAINT_NAME 
WHERE TC.CONSTRAINT_TYPE = 'PRIMARY KEY' 
AND TC.TABLE_SCHEMA = @Table_Schema 
AND TC.TABLE_NAME = @Table_Name 
ORDER BY CU.COLUMN_NAME 
FOR 
XML PATH('') 
), 1, 9, '') 
IF @PkColumn IS NULL 
SELECT @PkColumn = 'cast(NULL as nvarchar(max))' 
-- set select statement using dynamic UNPIVOT 
SET @SQL = 'select *, ' + QUOTENAME(@Table_Schema, '''') 
+ 'as [Table Schema], ' + QUOTENAME(@Table_Name, '''') 
+ ' as [Table Name]' + ' from 
(select ' + @PkColumn + ' as [PK Column], ' + @Cols + ' from ' 
+ QUOTENAME(@Table_Schema) + '.' + QUOTENAME(@Table_Name) 
+ ' )src UNPIVOT ([Column Value] for [Column Name] IN (' 
+ @Columns + ')) unpvt 
WHERE [Column Value] = @SearchValue' 
--print @SQL -- if we get errors, we may want to print generated SQL 
INSERT #RESULT 
( [PK COLUMN] , 
[COLUMN VALUE] , 
[COLUMN Name] , 
[TABLE SCHEMA] , 
[TABLE Name] 
) 
EXECUTE sp_ExecuteSQL @SQL, N'@SearchValue int', @SearchValue 
PRINT 'Found ' + CAST(@@ROWCOUNT AS VARCHAR(10)) + ' records in ' 
+ QUOTENAME(@Table_Schema) + '.' + QUOTENAME(@Table_Name) 
END 
CLOSE curAllTables 
DEALLOCATE curAllTables 
SELECT * 
FROM #RESULT 
ORDER BY [TABLE SCHEMA] , 
[TABLE Name] 
END 

代码如下:

 
USE [NORTHWIND] 
GO 
/****** Object: StoredProcedure [dbo].[My_Search_Int_AllTables] Script Date: 09/25/2011 15:48:29 ******/ 
SET ANSI_NULLS OFF 
GO 
SET QUOTED_IDENTIFIER OFF 
GO 
CREATE PROC [dbo].[My_Search_Int_AllTables] 
( 
@SearchValue INT 
) 
AS 
BEGIN 
CREATE TABLE #RESULT ([PK COLUMN] NVARCHAR(MAX), [COLUMN VALUE] NVARCHAR(MAX), [COLUMN Name] sysname, 
[TABLE SCHEMA] sysname, [TABLE Name] sysname) 
DECLARE @Table_Name sysname, @Table_Schema sysname 
DECLARE curAllTables CURSOR LOCAL FORWARD_ONLY STATIC READ_ONLY 
FOR 
SELECT Table_Schema, Table_Name 
FROM INFORMATION_SCHEMA.Tables 
WHERE TABLE_TYPE = 'BASE TABLE' 
ORDER BY Table_Schema, Table_Name 
OPEN curAllTables 
FETCH curAllTables 
INTO @Table_Schema, @Table_Name 
WHILE (@@FETCH_STATUS = 0) -- Loop through all tables in the database 
BEGIN 
INSERT #RESULT 
EXECUTE My_Search_StringInGivenTable @SearchValue, @Table_Schema, @Table_Name 
FETCH curAllTables 
INTO @Table_Schema, @Table_Name 
END -- while 
CLOSE curAllTables 
DEALLOCATE curAllTables 
-- Return results 
SELECT * FROM #RESULT ORDER BY [Table Name] 
END 

代码如下:

 
USE [NORTHWIND] 
GO 
DECLARE @return_value int 
EXEC @return_value = [dbo].[My_Search_Int_AllTables] 
@SearchValue = 68 
SELECT 'Return Value' = @return_value 
GO
