Executing Statements

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 Name, CloseDate FROM Dataset_Opportunity");
if (ret) {
  ResultSet rs=stat.getResultSet();
  while(rs.next()) {
    for(int i=1;i<=rs.getMetaData().getColumnCount();i++) {
      System.out.println(rs.getMetaData().getColumnName(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 Dataset_Opportunity (Name, CloseDate) VALUES ('Name','CloseDate')");

Upsert

Executing an upsert is the same as an insert: you can use the generic execute method or executeUpdate. For example:

Statement stat = conn.createStatement();
int count = stat.executeUpdate("UPSERT INTO Dataset_Opportunity (Name, CloseDate) VALUES ('Name','CloseDate')");

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 Dataset_Opportunity SET Name = 'XXX' , CloseDate = 'YYY' WHERE Id = '25'");
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 Dataset_Opportunity WHERE Id = '25'");
int count = stat.getUpdateCount();
