Accessing a column in the resultset object throws a No Such column labeled error

[kkrishrao]

Hello
We have a table in BigQuery with 4 columns
originaleventtime | TIMESTAMP | REQUIRED
operationcontextid | INTEGER | REQUIRED  
identifier | INTEGER | REQUIRED  
region | STRING | NULLABLE

The JDBC URL is
connection = DriverManager.getConnection("jdbc:BQDriver:int-a-fas-pdo/kkdataset?withServiceAccount=true&user=spanner-faspdo-kk@int-a-fas-pdo.iam.gserviceaccount.com&password=c:\FASGITHUB\int-a-fas-pdo-0757cb5e11b8.json");

We execute a select * on this table
PreparedStatement pstmt = connection.prepareStatement("select * from kk1");
ResultSet rest = pstmt.executeQuery();
But the line
Object originaleventtime=rest.getObject("originaleventtime");

throws an error
net.starschema.clouddb.jdbc.BQSQLException: No Such column labeled: originaleventtime
at net.starschema.clouddb.jdbc.BQForwardOnlyResultSet.findColumn(BQForwardOnlyResultSet.java:588)
at net.starschema.clouddb.jdbc.BQForwardOnlyResultSet.getObject(BQForwardOnlyResultSet.java:1170)

The method findColumn(String columnLabel) has the following implementation.
Why does it use getCatalogName() instaed of getColumnName()

int columncount = this.getMetaData().getColumnCount();
for (int i = 1; i <= columncount; i++) {
  if (this.getMetaData().getCatalogName(i).equals(columnLabel)) {
    return i;
  }

}

The getCatalogName returns the value int-a-fas-pdo

This is the bug in code
if (this.getMetaData().getCatalogName(i).equals(columnLabel)) {
return i;
}
this.getMetaData().getCatalogName(i) -> returns datasetname
should e replace with
if (rest.getMetaData().getColumnName(i).equals(columnLabel)) {
return i;
}
this.getMetaData().getCatalogName(i) replace with rest.getMetaData().getColumnName(i)

I raise the PR for fix this issue. I met this also. #162
