After Connecting from Code, you can execute SQL statements with the Statement class. See Using Prepared Statements to execute parameterized statements.

Select

To execute SQL statements that return data, use the Statement class' generic execute method or the executeQuery method. To return the results of a query, call the getResultSet method of the Statement.

The following example calls the execute method and iterates over the results returned:

Statement stat = conn.createStatement();
boolean ret = stat.execute("SELECT Id, Column1 FROM [CData].[QuickBase].SampleTable_1");
if (ret) {
  ResultSet rs=stat.getResultSet();
  while(rs.next()) {
    for(int i=1;i<=rs.getMetaData().getColumnCount();i++) {
      System.out.println(rs.getMetaData().getColumnLabel(i) +"="+rs.getString(i));
    }
  }
}

Insert

To execute an INSERT, use the generic execute method or the executeUpdate method of the Statement class. For example:

Statement stat = conn.createStatement();
int count = stat.executeUpdate("INSERT INTO [CData].[QuickBase].SampleTable_1 (Id, Column1) VALUES ('Id','Column1')");

Update

To execute an update, use the generic execute method or the executeUpdate method of the Statement class. You can call the getUpdateCount method to obtain the count of affected rows. Or, call the executeUpdate method; this method returns the row count. For example:

Statement stat = conn.createStatement();
stat.execute("UPDATE [CData].[QuickBase].SampleTable_1 SET Id = 'XXX' , Column1 = 'YYY' WHERE Id = '6'");
int count = stat.getUpdateCount();

Delete

To execute a delete, use the generic execute method or the executeUpdate method of the Statement class. You can call the getUpdateCount method to obtain the count of affected rows. Or, call the executeUpdate method; this method returns the row count. For example:

Statement stat = conn.createStatement();
stat.execute("DELETE FROM [CData].[QuickBase].SampleTable_1 WHERE Id = '6'");
int count = stat.getUpdateCount();
