SQL數據庫搜索

Question

我想知道是否有可能在整個sql數據庫中搜索一串數據？

我知道你可以搜索特定的列標題等，但我需要搜索數據的一個字符串，不知道從哪裏數據庫（表/列等）也將舉行。

可能嗎？我將如何做到這一點，以便返回列，表或兩者兼有的地方？

任何意見大加讚賞。

（我使用SQL Server Management Studio 2005中）

Answer 1

你可以寫一個腳本開始

select *, COLUMN_NAME, TABLE_NAME 
from INFORMATION_SCHEMA.COLUMNS 
where TABLE_SCHEMA = 'your_schema' 

隨着表和列的該列表，你可以遍歷所有的人都在尋找你的意見。

Answer 2

這是我到底使用的腳本。非常直截了當，一個偉大的小事情要知道。

CREATE PROCEDURE FindMyData_String 
    @DataToFind NVARCHAR(4000), 
    @ExactMatch BIT = 0 
AS 
SET NOCOUNT ON 

DECLARE @Temp TABLE(RowId INT IDENTITY(1,1), SchemaName sysname, TableName sysname, ColumnName SysName, DataType VARCHAR(100), DataFound BIT) 

    INSERT INTO @Temp(TableName,SchemaName, ColumnName, DataType) 
    SELECT C.Table_Name,C.TABLE_SCHEMA, C.Column_Name, C.Data_Type 
    FROM Information_Schema.Columns AS C 
      INNER Join Information_Schema.Tables AS T 
       ON C.Table_Name = T.Table_Name 
     AND C.TABLE_SCHEMA = T.TABLE_SCHEMA 
    WHERE Table_Type = 'Base Table' 
      And Data_Type In ('ntext','text','nvarchar','nchar','varchar','char') 


DECLARE @i INT 
DECLARE @MAX INT 
DECLARE @TableName sysname 
DECLARE @ColumnName sysname 
DECLARE @SchemaName sysname 
DECLARE @SQL NVARCHAR(4000) 
DECLARE @PARAMETERS NVARCHAR(4000) 
DECLARE @DataExists BIT 
DECLARE @SQLTemplate NVARCHAR(4000) 

SELECT @SQLTemplate = CASE WHEN @ExactMatch = 1 
          THEN 'If Exists(Select * 
              From ReplaceTableName 
              Where Convert(nVarChar(4000), [ReplaceColumnName]) 
                 = ''' + @DataToFind + ''' 
             ) 
            Set @DataExists = 1 
           Else 
            Set @DataExists = 0' 
          ELSE 'If Exists(Select * 
              From ReplaceTableName 
              Where Convert(nVarChar(4000), [ReplaceColumnName]) 
                 Like ''%' + @DataToFind + '%'' 
             ) 
            Set @DataExists = 1 
           Else 
            Set @DataExists = 0' 
          END, 
     @PARAMETERS = '@DataExists Bit OUTPUT', 
     @i = 1 

SELECT @i = 1, @MAX = MAX(RowId) 
FROM @Temp 

WHILE @i <= @MAX 
    BEGIN 
     SELECT @SQL = REPLACE(REPLACE(@SQLTemplate, 'ReplaceTableName', QUOTENAME(SchemaName) + '.' + QUOTENAME(TableName)), 'ReplaceColumnName', ColumnName) 
     FROM @Temp 
     WHERE RowId = @i 


     PRINT @SQL 
     EXEC SP_EXECUTESQL @SQL, @PARAMETERS, @DataExists = @DataExists OUTPUT 

     IF @DataExists =1 
      UPDATE @Temp SET DataFound = 1 WHERE RowId = @i 

     SET @i = @i + 1 
    END 

SELECT SchemaName,TableName, ColumnName 
FROM @Temp 
WHERE DataFound = 1 
GO
