public static StatementKey newPrepared(java.lang.String sql,
                                       java.lang.String schema,
                                       int holdability)
```
    Creates a key for a query with default settings.
    Defaults are according to the JDBC standard; result set type will be ResultSet.TYPE_FORWARD_ONLY, concurrency will be ResultSet.CONCUR_READ_ONLY and the statement will not return auto-generated keys.
    
    Parameters:
    
    sql - SQL query string
    
    schema - current compilation schema
    
    holdability - result set holdability
    
    Returns:
    
    A statement key.
  - newPrepared
```
public static StatementKey newPrepared(java.lang.String sql,
                                       java.lang.String schema,
                                       int holdability,
                                       int autogeneratedKeys)
```
    Creates a key for a query specifying whether auto-generated keys shall be returned.
    Unspecified settings will be according to the JDBC standard; result set type will be ResultSet.TYPE_FORWARD_ONLY, concurrency will be ResultSet.CONCUR_READ_ONLY.
    
    Parameters:
    
    sql - SQL query string
    
    schema - current compilation schema
    
    holdability - result set holdability
    
    autogeneratedKeys - tells whether or not to reutrn auto-generated keys
    
    Returns:
    
    A statement key.
