Question

I write my procedure and I have this errors :

Declare @code1 varchar(10), @code2 varchar(10), @lettre2 varchar(5), @lettre3 varchar(5), @lettre4 varchar(5);

SET @code2 = NULL;
SET @lettre2 = NULL;
SET @lettre3 = NULL;
SET @lettre4 = NULL;

DECLARE curseur1 CURSOR FOR 
    SELECT TOP 1 Code 
    FROM Configuration..ngap 
    ORDER BY 'Code';

OPEN curseur1

FETCH NEXT FROM curseur1 INTO @code1;

WHILE @@FETCH_STATUS = 0
BEGIN
    if @code1 <> @code2
        INSERT INTO Configuration..ngap2 
        VALUES ('@code1', 'select top 1 Description_acte from Configuration..ngap where Code='@code1' order by 'Code'',  'select top 1 Lettre from Configuration..ngap where Code='@code1' order by 'Code'', 'select top 1 Coef from Configuration..ngap where Code='@code1' order by 'Code'')

    if @code1 = @code2
        SET @lettre2 = (select lettre2 from Configuration..ngap2 where Code='@code1');

    SET @lettre3 = (select lettre3 from Configuration..ngap2 where Code='@code1');
    SET @lettre4 = (select lettre4 from Configuration..ngap2 where Code='@code1');

    if @lettre2 IS NULL
        UPDATE Configuration..ngap2 
        SET lettre2 = (select Lettre from Configuration..ngap where Code='@code1' and index_count=2)

    UPDATE Configuration..ngap2 
    SET Coef2 = (select Coef from Configuration..ngap where Code='@code1' and index_count=2)

    if @lettre3 IS NULL
        UPDATE Configuration..ngap2 
        SET lettre3 = (select Lettre from Configuration..ngap where Code='@code1' and index_count=3)

    UPDATE Configuration..ngap2 
    SET Coef3 = (select Coef from Configuration..ngap where Code='@code1' and index_count=3)

Answer 1

This is your problem

insert into Configuration..ngap2 
values ('@code1', 
        'select top 1 Description_acte from Configuration..ngap where Code='@code1' order by 'Code'',  
        'select top 1 Lettre from Configuration..ngap where Code='@code1' order by 'Code'', 
        'select top 1 Coef from Configuration..ngap where Code='@code1' order by 'Code'')

You are trying to run the string into a value...

Try:

insert into Configuration..ngap2 
values ('@code1', 
        'select top 1 Description_acte from Configuration..ngap where Code=' + @code1 + ' order by Code',  
        'select top 1 Lettre from Configuration..ngap where Code=' + @code1 + ' order by Code', 
        'select top 1 Coef from Configuration..ngap where Code=' + @code1 +' order by Code')

And the second issue:

@code2=@code1;

Try

set @code2=@code1;
