Subject [jira] [Created] (DBUTILS-130) QueryRunner cannot correctly insert unicode characters in Oracle Database.
Date Mon, 26 Sep 2016 17:09:20 GMT
Kaleb Akalework created DBUTILS-130:

             Summary: QueryRunner cannot correctly insert unicode characters in Oracle Database.

                 Key: DBUTILS-130
             Project: Commons DbUtils
          Issue Type: Bug
    Affects Versions: 1.5
            Reporter: Kaleb Akalework

I have used queryRunner to insert unicode characters succesfully in MSSQL and IBM DB2. I was
not able to successfully insert unicode into Oracle. Instead I see the reversed questions
mark are inserted, in place of the acutal data. This is the code. The below code works fine
If I'm using SQL Server 2016 or IBM DB2 10.5. 

Here is a sample java code I'm using. The followoing code works perfectly if executed against
SQL Server database. 

to create the table use create table TEST (test NCLOB) 

private Object[][] getBulkWriteParams() throws SQLException{ 
List<Object[]> listOfParams = new ArrayList<>(); 
String s = "こんにちは"; 
//for(ContentEntry ce:cacheOfExtractedPages){ 
listOfParams.add(new Object []{s}); 
catch(Exception e){ 
int i= 1; 

return listOfParams.toArray(new Object[0][0]); 

public void insertQueryRunner(){ 
String s = "こんにちは"; 
String SQL = "insert into TEST VALUES( ?)"; 

new QueryRunner().batch(connection, SQL, getBulkWriteParams()); 
}catch(Exception e){}
