Home -> Community -> Mailing Lists -> Oracle-L -> RE: JDBC question
Thanks Val for the info. The Java code was actually compiled under JDK 1.2
and the environment was set up to have classes12.zip in the CLASSPATH (in
8.1.6).
I have had a look at JDBC 8.1.6.0.1 from OTN and the README file does not indicate a fix for this problem. However I will down load and try it.
Cheers
Long

Subject: RE: JDBC question
It is a valid syntax for JDBC. The prepare call will take care of passing this sql statement to Oracle in the right format.
As far as the issue goes:
1) It's a bug in 8.1.5 and 8.1.6 version of JDBC drivers that he got (get
the latest patch from technet)
2) He is using JDK1.1 instead of JDK1.2 which 8.1.5 and 8.1.6 drivers are
meant for.
In other words, for him to be able to use 8.1.5/8.1.6 drivers he needs to compile and run his app with JDK1.2.

I don't know java, either.
But in java, is this legal SQL syntax? "where divid = ?";

Hi,
A developer here has encountered a problem with using JDBC accessing Oracle
so he came to me (a DBA) for help. Unfortunately I do not know much about
Java stuff, hope that someone in this list could help me. The following
Java
code uses Oracle JDBC thin driver to do a select using prepared statement.
1) The code works fine with Oracle 8.0.4 (using the JDBC drivers that come
with 8.0.4)
2) The code does not work with 8.1.5 or 8.1.6 (using the JDBC drives that
come with Oracle 8.1.5/8.1.6). Under 8.1.5/8.1.6 it gave "ORA-01008: not
all
variables bound". However if I issued the same SELECT statment under
sqlplus, it works fine.
divid is a NOT NULL CHAR(2) field.
import java.sql.*;
public class TestOraclePrepStmt {
public static void main(String argv[]) throws Exception {
Class.forName("oracle.jdbc.driver.OracleDriver") ;
Connection conn = DriverManager.getConnection(
"jdbc:oracle:thin:@rocky:1521:PSS",
"pss", "psspwd");
String divId = "93" ;
String query = "select min(finyear) " +
"from sector_target_balances " +
"where divid = ?";
PreparedStatement mainStmt = conn.prepareStatement(query) ;
mainStmt.setString(1, divId);
ResultSet mainResult = mainStmt.executeQuery(query) ;
String minFinYear="", maxFinYear="";
while (mainResult.next()) { // for each row
minFinYear = mainResult.getString(1);
maxFinYear = mainResult.getString(2);
} // next row
System.out.println("minFinYear "+ minFinYear + "maxFinYear
"
conn.close();
}
