Script zum finden von bestimmten Werten in SQL

Johannes Nöbauer
Autor: Johannes Nöbauer

Dieses SQL Script ermöglicht es nach einem bestimmten Werten in allen Tables inerhalb einer Datenbank zu suchen. Ich lege dieses Script in allen Master-Datenbanken als Stored-Procedure ab um es immer zur Hand zu haben.

DECLARE @value VARCHAR(64)
DECLARE @sql VARCHAR(1024)
DECLARE @table VARCHAR(64)
DECLARE @column VARCHAR(64)

SET @value = ‚valuehere‘

CREATE TABLE #t (
tablename VARCHAR(64),
columnname VARCHAR(64)
)

DECLARE TABLES CURSOR
FOR

SELECT o.name, c.name
FROM syscolumns c
INNER JOIN sysobjects o ON c.id = o.id
WHERE o.type = ‚U‘ AND c.xtype IN (167, 175, 231, 239)
ORDER BY o.name, c.name

OPEN TABLES

FETCH NEXT FROM TABLES
INTO @table, @column

WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = ‚IF EXISTS(SELECT NULL FROM [‚ + @table + ‚] ‚
–SET @sql = @sql + ‚WHERE RTRIM(LTRIM([‚ + @column + ‚])) = “‘ + @value + “‘) ‚
SET @sql = @sql + ‚WHERE RTRIM(LTRIM([‚ + @column + ‚])) LIKE “%‘ + @value + ‚%“) ‚
SET @sql = @sql + ‚INSERT INTO #t VALUES (“‘ + @table + “‘, “‘
SET @sql = @sql + @column + “‘)‘

EXEC(@sql)

FETCH NEXT FROM TABLES
INTO @table, @column
END

CLOSE TABLES
DEALLOCATE TABLES

SELECT *
FROM #t

DROP TABLE #t
