Problems with SQL

Question

I've got a big and terrible problem with a query. I'm trying to query a MS ACCESS db from my Java program, using IDSServer. That means that i need to import j102.sql.* instead of java.sql.*
The query is:
String querynumrioff = "SELECT DETTAGLI_OFFERTE.[Cod-nmg], DETT_RISP1.NUM_RISPOSTA, DETT_RISP1.DATA_COMPILAZIONE, DETTAGLI_OFFERTE.[Pos offerta], DETTAGLI_OFFERTE.[Codice NMG], DETTAGLI_OFFERTE.[Disegno NMG], DETTAGLI_OFFERTE.Descrizione, DETTAGLI_OFFERTE.[Rev disegno], DETTAGLI_OFFERTE.Um, DETTAGLI_OFFERTE.[Qt� lotto], DETTAGLI_OFFERTE.[Qt� annua], DETTAGLI_OFFERTE.[Prezzo obiettivo], DETTAGLI_OFFERTE.[Data cons off], DETTAGLI_OFFERTE.[Data cons mat], DETTAGLI_OFFERTE.Note, DETTAGLI_OFFERTE.[ID offerta] FROM DETTAGLI_OFFERTE LEFT JOIN DETT_RISP1 ON DETTAGLI_OFFERTE.[ID dettagli offerta] = DETT_RISP1.ID_DETTAGLI WHERE (((DETTAGLI_OFFERTE.[ID offerta])= '" + numoff + "'))";
The error message that I get is:
j102.sql.SQLException: [22018][Microsoft][Driver ODBC Microsoft Access] Tipi di dati non corrispondenti nell'espressione criterio.
That means something like "Data types not matching in the critera expression".
Could anybody help me finding a solution to this problem?
Thank you really much!

Answer 1

I used :
Integer gio=new
Integer(jTextFieldnumrioff.getText());
int numoff =gio.intValue() ;
But it still doesn't work
Thank you very much for you answer!
GiorgiLike I said, you don't use quotes around numbers in SQL
This is what you have:
WHERE (((DETTAGLI_OFFERTE.[ID offerta])= '" + numoff + "'))";
Let's say numoff = 10 Then your SQL is equivalent to
WHERE DETTAGLI_OFFERTE.[ID offerta] = '10';
'10' is a string 10 is a number. Change your SQL to this:
WHERE (((DETTAGLI_OFFERTE.[ID offerta])= " + numoff + "))";
