docs: Creates a <code>CallableStatement</code> object that will generate <code>ResultSet</code> objects with the given
  type and concurrency. This method is the same as the <code>prepareCall</code> method above, but it allows the
  default result set type, result set concurrency type and holdability to be overridden.
  
  @param sql                  a <code>String</code> object that is the SQL statement to be sent to the database;
  may contain on or more '?' parameters
  @param resultSetType        one of the following <code>ResultSet</code> constants: <code>ResultSet.TYPE_FORWARD_ONLY</code>,
  <code>ResultSet.TYPE_SCROLL_INSENSITIVE</code>, or <code>ResultSet.TYPE_SCROLL_SENSITIVE</code>
  @param resultSetConcurrency one of the following <code>ResultSet</code> constants: <code>ResultSet.CONCUR_READ_ONLY</code>
  or <code>ResultSet.CONCUR_UPDATABLE</code>
  @param resultSetHoldability one of the following <code>ResultSet</code> constants: <code>ResultSet.HOLD_CURSORS_OVER_COMMIT</code>
  or <code>ResultSet.CLOSE_CURSORS_AT_COMMIT</code>
  @return a new <code>CallableStatement</code> object, containing the pre-compiled SQL statement, that will
  generate <code>ResultSet</code> objects with the given type, concurrency, and holdability
  @throws java.sql.SQLException if a database access error occurs, this method is called on a closed connection or
  the given parameters are not <code>ResultSet</code> constants indicating type,
  concurrency, and holdability
  @throws java.sql.SQLFeatureNotSupportedException
  if the JDBC driver does not support this method or this method is not supported for
  the specified result set type, result set holdability and result set concurrency.
