哪個表包含此數據+ SQL

Question

我有一個包含100個表的數據庫。 我怎麼知道哪個表包含特定的文本。

例如該表中包含文本「假定壽命聲明」

我可以給一個暗示，這是申請一個varchar

ypercube的建議是完全正確的。這裏是一個實現：

DECLARE @searchText VARCHAR(100) 
SET @searchText = 'Assumed Life Claims' 

DECLARE @sqlText VARCHAR(8000) 
DECLARE @MaxId INT 
DECLARE @CurId INT 
DECLARE @possibleColumns TABLE (Id INT IDENTITY(1, 1) NOT NULL PRIMARY KEY 
           ,sqlText VARCHAR(8000)) 
INSERT INTO @possibleColumns(sqlText) 
SELECT 'IF EXISTS (SELECT * FROM ' + c.TABLE_NAME + ' WHERE ' + c.COLUMN_NAME + ' = ''' + @searchText + ''') PRINT '' searchText=' + @searchText + ' was found in ' + c.TABLE_NAME + '.' + c.COLUMN_NAME + '''' 
    FROM INFORMATION_SCHEMA.COLUMNS c 
    -- Using hint that this field is a varchar 
WHERE c.DATA_TYPE = 'varchar' 

SELECT @CurId = MIN(pc.Id) 
     ,@MaxId = MAX(pc.Id) 
    FROM @possibleColumns pc 

WHILE (@CurId <= @MaxId) 
BEGIN 
    SELECT @sqlText = pc.sqlText 
     FROM @possibleColumns pc 
    WHERE pc.Id = @CurId 

    -- For testing (uncomment) 
    --PRINT @sqlText 

    EXEC(@sqlText) 

    -- Increment counter 
    SET @CurId = @CurId + 1 
END
