CREATE FUNCTION dbo.calculer_montant ( ) RETURNS DECIMAL(18,2) -- BEGIN DECLARE @montant_ttc decimal(18,2); DECLARE @num varchar(200); set @montant_ttc= (SELECT SUM(brm.Montant) * SUM(brm.TVA) FROM marche m LEFT OUTER JOIN bon_reception_marche brm ON m.Id_marche = brm.Id_marche WHERE Num_marche = @num) END ------------------- Here the @num variable which you are using what should be the value? I think @num is a parameter which needs to be sent at the time of calling the function. If Yes? Then .. check the below function. CREATE FUNCTION dbo.calculer_montant ( @num varchar(200) ) RETURNS DECIMAL(18,2) BEGIN DECLARE @montant_ttc decimal(18,2); --DECLARE @num varchar(200); set @montant_ttc= (SELECT SUM(brm.Montant) * SUM(brm.TVA) FROM marche m LEFT OUTER JOIN bon_reception_marche brm ON m.Id_marche = brm.Id_marche WHERE Num_marche = @num) END

CREATE FUNCTION calculer_montant ( ) RETURNS DOUBLE AS BEGIN DECLARE @montant_ttc double DECLARE @num varchar(200) set @montant_ttc= (select sum(brm.Montant) * sum(brm.TVA) from marche m left outer join bon_reception_marche brm on m.Id_marche = brm.Id_marche where Num_marche=@num) RETURN @montant_ttc END I tried this code but it does not work here are the errors that sends me sql Msg 156, Niveau 15, État 1, Procédure calculer_montant, Ligne 8 Syntaxe incorrecte vers le mot clé 'DECLARE'. Msg 137, Niveau 15, État 1, Procédure calculer_montant, Ligne 9 La variable scalaire "@montant_ttc" doit être déclarée. Msg 137, Niveau 15, État 2, Procédure calculer_montant, Ligne 10 La variable scalaire "@montant_ttc" doit être déclarée.

Here is what I created but it does not work the sql server returns an error message "Msg 156, Level 15, State 1, Procedure compute_montant, Line 3 Incorrect syntax to keyword 'As'. " create function calculer_montant() returns double As begin declare @num varchar(200); return select sum(brm.Montant) * sum(brm.TVA) from marche m left outer join bon_reception_marche brm on m.Id_marche = brm.Id_marche where Num_marche=@num end
