java - Sybase JConnect: ENABLE_BULK_LOAD usage

Question

Can anyone out there provide an example of bulk inserts via JConnect (with ENABLE_BULK_LOAD) to Sybase ASE?

I've scoured the internet and found nothing.

Answer 1

I got in touch with one of the engineers at Sybase and they provided me a code sample. So, I get to answer my own question.

Basically here is a rundown, as the code sample is pretty large... This assumes a lot of pre initialized variables, but otherwise it would be a few hundred lines. Anyone interested should get the idea. This can yield up to 22K insertions a second in a perfect world (as per Sybase anyway).

SybDriver sybDriver = (SybDriver) Class.forName("com.sybase.jdbc3.jdbc.SybDriver").newInstance();
sybDriver.setVersion(com.sybase.jdbcx.SybDriver.VERSION_6);
DriverManager.registerDriver(sybDriver);

//DBProps (after including normal login/password etc.
props.put("ENABLE_BULK_LOAD","true");

//open connection here for  sybDriver

dbConn.setAutoCommit(false);    
String SQLString = "insert into batch_inserts (row_id, colname1, colname2)
 values (?,?,?) 
";

PreparedStatement   pstmt;
try
{
   pstmt = dbConn.prepareStatement(SQLString);      
}
catch (SQLException sqle)
{
   displaySQLEx("Couldn't prepare statement",sqle);
   return;
}

for (String[] val : valuesToInsert)
{
   pstmt.setString(1, val[0]);  //row_id    varchar(30)
   pstmt.setString(2, val[1]);//logical_server varchar(30)
   pstmt.setString(3, val[2]);  //client_host varchar(30)

   try
   {
      pstmt.addBatch();
   }
   catch (SQLException sqle)
   {
      displaySQLEx("Failed to build batch",sqle);
      break;
   }
}

try {
   pstmt.executeBatch();
   dbConn.commit();
   pstmt.close();
} catch (SQLException sqle) {
   //handle
}

try {
   if (dbConn != null)
      dbConn.close();
} catch (Exception e) {
   //handle
}
