"Ya se ha agregado un elemento con la misma clave" Error en SSRS al intentar establecer el conjunto de datos

Question

Cuando intento establecer el conjunto de datos en SSRS IDE, aparece el error que aparece en la instantánea.

La consulta funciona totalmente bien en SQL Server Management Studio, me pregunto dónde me salió mal?

La conexión a DB está bien establecida.

OPCIONAL:

En caso de que quiera echar un vistazo a mi consulta (es demasiado largo), he comprobado muy bien. No hay nada malo en ella:

Answer 1

Después de formatear su guión un poco, me di cuenta de que hay 2 columnas con el mismo nombre que está seleccionando. Asegúrese de cambiar el nombre final & que cada columna cuando ejecuta su extracto en Management Studio tiene un único nombre.

Dicho esto, las dos columnas que noté tienen nombres duplicados son customerquoteproducts.istaxpaid y customershipping.istaxpaid

espero que ayude!

Answer 2

Me encontré con esta publicación hoy cuando recibí el mismo problema. Mi problema sin embargo fue un poco diferente.

Tenía una tabla temporal y una declaración If en mi SP. Así que mi SP parecía algo como esto:

DECLARE @myCheck as int 
SET @myCheck = 0 

SELECT @myCheck = CASE WHEN [checkfield] = 'xxx' then 1 else 0 end 
    FROM checktable 
    WHERE ... 


SELECT myfields.* 
into #temptable 
FROM mytable 
WHERE ... 


IF @myCheck = 1  --if ssrs does'nt want ot refresh your fields, remove hte if as it does not see past this... 
    select * 
    FROM #temptable 
     LEFT JOIN tableA 
      ON ... 
ELSE 
    select * 
    FROM #temptable 
     LEFT JOIN tableB 
      ON ... 

Así que con el fin de "refrescar" mis campos en SSRS, comenté a cabo la instrucción If y se mantiene una de mis consultas con los nombres de campo. sólo tenía que acordarse de añadir todo de nuevo después ...
