SET QUOTED_IDENTIFIER ON

CREATE PROCEDURE [dbo].[FindValueInAllTables]
 @SearchValue DECIMAL

 DECLARE @TableName NVARCHAR(256);
 DECLARE @ColumnName NVARCHAR(256);
 DECLARE @SearchStr NVARCHAR(256);
 DECLARE @SQL NVARCHAR(MAX);
 
 DECLARE Cur CURSOR FOR

 EXEC sp_executesql @SearchStr;
 
 FETCH NEXT FROM Cur INTO @TableName, @ColumnName;
 END
 
 CLOSE Cur;
 DEALLOCATE Cur;
END

GO

然后執(zhí)行：EXEC FindValueInAllTables @SearchValue = 7005;

第二步根據(jù)字段名稱查詢表名,在sqlserver中如何根據(jù)字段名查找字段所在的表:記下相應(yīng)的值如： tid = 304387

select a.name TableName, b.name FieldName
from sysobjects a,syscolumns b 
where a.id=b.id and b.name='FieldName' and a.type='U'

找到表名：
select * from tablename where tid = 304387
UPDATE tablename SET DATETIME='2024-06-05 00:25:53' where tid = 304387

查找中文內(nèi)容：

USE [dpyd2024]
GO
/****** Object: StoredProcedure [dbo].[FindValueInAllTables]  Script Date: 02/11/2025 16:54:11 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO


ALTER PROCEDURE [dbo].[FindValueInAllTables]
 @SearchValue nvarchar
AS
BEGIN
 SET NOCOUNT ON;
 
 DECLARE @TableName NVARCHAR(256);
 DECLARE @ColumnName NVARCHAR(256);
 DECLARE @SearchStr NVARCHAR(256);
 DECLARE @SQL NVARCHAR(MAX);
 
 DECLARE Cur CURSOR FOR 
 SELECT TABLE_NAME, COLUMN_NAME
 FROM INFORMATION_SCHEMA.COLUMNS
 WHERE DATA_TYPE IN ('nvarchar', 'varchar')
 ORDER BY TABLE_NAME, ORDINAL_POSITION;
 
 OPEN Cur;
 
 FETCH NEXT FROM Cur INTO @TableName, @ColumnName;
 
  -- 聲明一個變量來存儲計數(shù)結(jié)果
  DECLARE @TotalCount INT;
   DECLARE @SearchStr2 NVARCHAR(256);
 DECLARE @show_num varchar(9);
 WHILE @@FETCH_STATUS = 0
 BEGIN
 
 SET @SearchStr = 'SELECT * FROM [' + @TableName + '] WHERE [' + @ColumnName + '] like '''+@SearchValue+'%'' ';
 SET @SearchStr2 = 'SELECT @a = count(*) FROM [' + @TableName + '] WHERE [' + @ColumnName + '] like '''+@SearchValue+'%'' ';
 
 exec sp_executesql @SearchStr2,N'@a int output',@show_num output ;
 set @TotalCount=cast(@show_num as int);
 
 ---if
 if @TotalCount > 0
 begin 
 select @TableName ;
 select @SearchStr ;
  EXEC sp_executesql @SearchStr;
 end 
 ---if 
 FETCH NEXT FROM Cur INTO @TableName, @ColumnName;
 END
 
 CLOSE Cur;
 DEALLOCATE Cur;
END

EXEC FindValueInAllTables @SearchValue = '珊珊';
