Wie schreibe ich SQL-Skript, um Zeilen in allen Tabellen einer SQL Server-Datenbank zu finden, die eine Zeichenfolgespalte haben, deren Wert einem Schlüsselwort entspricht?

Question

Umgebung: Windows, SQL Server 2008

Zum Beispiel meiner Datenbank hat Tabelle 1, Tabelle 2, Tabelle 3 ... TableN hat jede Tabelle Column1, Column2, Column3 ... ColumnN. Einfach, sie sind alle String-Spalte.

Ich möchte Zeilen finden, egal aus welcher Tabelle, welche den Wert einer Spalte haben, ist 'Key' egal welche Spalte.

Wie schreibe ich ein Skript, das zu tun?

Danke!

dies versuchen, aber das wird nur funktionieren auf ähnliche strukturierte Tabelle

DECLARE @Table nvarchar(100), @Column nvarchar(100) 
DECLARE @SQLStringBuilder nvarchar(MAX) = '' 
DECLARE MY_CURSOR Cursor 
FOR SELECT sysobjects.name, syscolumns.name 
    FROM sysobjects 
    JOIN syscolumns ON sysobjects.id = syscolumns.id 
    JOIN systypes ON syscolumns.xtype=systypes.xtype 
    WHERE sysobjects.xtype='U' and systypes.name <> 'sysname' and systypes.name = 'nvarchar' 
ORDER BY sysobjects.name,syscolumns.colid 
Open MY_CURSOR 

Fetch NEXT FROM MY_CURSOR INTO @Table, @Column 
WHILE @@FETCH_STATUS = 0 
BEGIN 
    SET @SQLStringBuilder = @SQLStringBuilder + ' SELECT ''' + @Table + ''' as TableName, ''' + @Column + ''' as ColumnName, * FROM ' + @Table + ' WHERE ' + @Column+ ' = ''Key'' UNION ALL' 

Fetch NEXT FROM MY_CURSOR INTO @Table, @Column 

END 
CLOSE MY_CURSOR 
DEALLOCATE MY_CURSOR 
SET @SQLStringBuilder = SUBSTRING(@SQLStringBuilder, 0, LEN(@SQLStringBuilder)-9) 
EXEC(@SQLStringBuilder)

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

DECLARE @SearchStr nvarchar(100) 
SET @SearchStr = 'Wound' 

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 
      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') 
       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 
END
