#1.It seems that when procedure in a class was loaded, drop and
reloaded, the changes of JAR file havn't take effected!
Not quite sure what you did here, but did you look at/try the system
procedure REPLACE_JAR?
http://db.apache.org/derby/docs/10.8/tools/ttoolsjarload1003120.html
It seems you remove the jar before (re)installing it, that should work
as well, though..
Dag
eg script:
drop PROCEDURE test;
call sqlj.remove_jar('admin.creaateClient', 0);
call sqlj.install_jar('export\testproc.jar','admin.creaateClient', 0);
CREATE PROCEDURE test( IN orgID INTEGER,
IN groupID INTEGER,
IN name varchar(60),
IN faceFileID bigint,
IN recStatus smallint,
IN creator bigint
)
PARAMETER STYLE JAVA READS SQL DATA LANGUAGE JAVA
EXTERNAL NAME 'com.bana.commonServer.procedure.Client_info.creaateClient';
call test(1,2,'name',4,5,6);
-- code ended
when I change and re-complie the JAR ( a little changes of
logic,nothing of the other changeed), I repeat the script but the
logic is the old one...??
#2
sql = "SELECT groupSize,seq from SEQ where seqType =101 and orgID =?
and groupID =? ";
pSeq= connection.prepareStatement(sql,
ResultSet.TYPE_FORWARD_ONLY,ResultSet.CONCUR_UPDATABLE);
pSeq.setInt(1, orgID);
pSeq.setInt(2, groupID);
System.out.println(" exe SQL??"+sql);
rs = pSeq.executeQuery();
if(rs.next()){
groupSize =rs.getInt(1);
seq = rs.getInt(2);
System.out.println("seq:"+seq);
if(seq>=groupSize){
//returnCode[0] =4002;
return;
}
System.out.println("groupSize:"+groupSize);
rs.updateInt("seq", seq+1); /////////////not executed
rs.updateRow();//////////////////not executed
System.out.println("update:"+seq+1);//////////////////not executed
the return message is:
The exception 'java.sql.SQLException:........ ' was thrown while
evaluating an expression.
I try the same code in independent java source and execute passed.I
feel confused ,It my first time to try derby....
I look forward to your reply.thank you for you intention.
