Hi, i'm trying to display a result of a query, the query is the follow. . . .

select,c.nome,s.nome from richiesta as r,corso as c,studente as s where r.corso_oid=c.oid and r.studente_oid=s.oid and corso.docente_oid=:Docente;

The idea is to display in one unit the result of this query, I suppose to do that using a query unit with static select. . Searching the wiki for query unit i find out a tutorial showing me that i can use input parameters and out put parameters. .

So I've setted up a input parameters called Docente and coupled it correctly, so I've setted up the output for each columns in the select. but when i run the application an error occourse telling me that it can find a parameter called Docente!

So I can't figure out how to fix it, I've also no idea of wich part is giving me the error, is the query? or the parameters?

Thanks in advance!

Salve, sto cercando di visualizzare il risultato di una query in una query unit, ho creato i parametri di output e di input, ho fatto correttamente il coupling ma visualizzo un errore quando eseguo la app. mi dice che non trova il parametro che ho messo come parametro di input! Però non riesco a capire dove sia il problema, se sia colpa del parametro o della query sql che ho inserito!

Grazie in anticipo a tutti!

I've resolved the problem! probably was about the name of the parameter in input and in the query!!
