Déclencheur pour capture des DELETE

des tables traquées, alors il conviendrait de modifier les déclencheurs afin que soient spécifiées de manière exhaustive les colon – nes cibles dans les insertions des tables d’historisation.

Listing 7
CREATE TRIGGER dbo.E_D_CLI
ON dbo.T_CLIENT_CLI
FOR DELETE
AS
BEGIN
INSERT INTO DB_HST_LIGNE.dbo.T_CLIENT_CLI (_MA, _MD, CLI_ID,
CLI_NOM, CLI_PRENOM)
SELECT client_net_address, ‘D’, d.*
FROM deleted d
CROSS JOIN sys.dm_exec_connections
WHERE session_id = @@SPID
END

Listing 8
SET @SQL = ‘CREATE TRIGGER E_D_’ + SUBSTRING(@TAB, LEN(@TAB) -2, 3) +
‘ ON ‘ + @SCH + ‘.’ + @TAB +
‘ FOR DELETE AS SET NOCOUNT ON BEGIN INSERT INTO DB_HST_LIGNE.’
+ @SCH + ‘.’ + @TAB + ‘ (_MA, _MD, ‘;
SELECT @SQL = @SQL + COLUMN_NAME + ‘, ‘
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_SCHEMA = @SCH
AND TABLE_NAME = @TAB;
SET @SQL = SUBSTRING(@SQL, 1, LEN(@SQL) – 1) + ‘) ‘+
‘SELECT client_net_address,  »D », d.* ‘ +
‘FROM deleted d ‘ +
‘CROSS JOIN sys.dm_exec_connections ‘ +
‘WHERE session_id = @@SPID ‘ +
‘END ‘
EXEC (@SQL);
