Fetch oracle data VARCHAR2(N BYTE) return blank string in JAVA
I would like to know what's going on when, I'm trying to fetch data from ORACLE database. The datatype of the column is VARCHAR2(40 BYTE) NOT NULL ENABLE.
From @Thoma advise in comment section I've changed the pics into text.
In SQL DEVELOPPER, I have the following result
SELECT ZONE_DESC FROM IC_RATE_ZONES;
"ZONE_DESC"
VIRGIN ISLANDS UK
VIRGIN ISLANDS US
WALLIS AND FUTUNA IS
YEMEN
ZAMBIA
ZAMBIA MOBILE
And when I've tried to fetch those data in JAVA code:
try{
con = conn.getOracle();
stm = con.createStatement();
Rs = stm.executeQuery("select ZONE_DESC FROM IC_RATE_ZONES");
while(Rs.next()){
System.out.println(Rs.getString("ZONE_DESC"));
}
} catch(Exception e){
e.printStackTrace();
}
I get a blank result in my console output.

Instead of posting images you might want to post at least your code in properly formatted text form. This makes it easier to preserve (images can get deleted) and work with - and it shows some effort on your part.

@Thomas, sorry for this. this is a remote host and I cannot copy it because of the restriction. I'll try to write it all and post the text later.

What did you expect on the console? You add data to your model but you do not log the actual data to the console. TrySystem.out.print(Rs.getString(1))

THANKS A LOT FOR EVERYONE THAT take the time to answer it. the solution has been mentionned by @secretsuperstar in the comment section but i've do it wrong the first time.
https://bjurr.com/jdbc-problem-resultset-getstring-returns-nothing/
It have to get the ASCII first and read it. The datatype made it complicated.
here is the final result :
try{
con = conn.getOracle();
stm = con.createStatement();
Rs = stm.executeQuery("select ZONE_DESC FROM IC_RATE_ZONES");
while(Rs.next()){
String str = new String();
InputStreamReader in = new InputStreamReader(Rs.getAsciiStream("ZONE_DESC"));
while(in.ready()){
str = str + (char)in.read();
}
System.out.println(str);
}
} catch(Exception e){
e.printStackTrace();
}
thank you all. HOPE IT HELP SOMEONE ELSE
