Ma fonction retourne un code incompréhensible pas trés loin du code stocké dans la base.

Ma question est est ce que la traduction en sql est faute à votre avis.
Merci d'avance

Bonjour

le premier code que tu mets n'est pas du VBA ou j'en perds mon latin.

bonjour philippe,

moi je suis pas un spécialisé dans la programmation des SGBD, on m'a dit que c du vba.

. C'est quel language alors?

**Kloun** · 02/12/2010, 09h39

Bonjour,

Ce n'est pas du VBA, c'est du Transact-SQL .

Et les 2 codes sont identiques.

**ilank** · 02/12/2010, 09h40

Bonjour,
?? Les deux codes sont des scripts Transact-SQL. Le premier modifie le code de la procédure stockée CodeConvert, le second la crée( il manque le 'C' à CREATE sur la première ligne).
Une première différence entre les deux codes

Code transact-SQL :

Sélectionner tout - Visualiser dans une fenêtre à part

	WHILE @i <= len(@Text)
	BEGIN
		SET @AscChar=ASCII(SUBSTRING(@Text,@i,1))
=>		SET @AscChar =27                              
	 IF(@AscChar= 27)

la ligne indiquée est absente dans le second script.

**mino26tz** · 02/12/2010, 10h03

salut

@ilan oui j'ai fait expret SET @AscChar =27 pour qu'il rentre dans la boucle if.

aprés quelques testes je me suis rendu compte que SUBSTRING(@Text,@i,1) ne retourne rien qui est bizarre car au début @i=0 et elle s'incrémente.

Merci d'avance

Si la question est de savoir pourquoi le code Transact-SQL n'est pas bon, ce n'est pas le bon forum, il faut aller poster du côté de SQL Server.
