# SQLRowStream 

###
Companion object SQLRowStream

#### class SQLRowStream extends ReadStream[JsonArray]

A ReadStream of Rows from the underlying RDBMS. This class follows the ReadStream semantics and will automatically close the underlying resources if all returned rows are returned. For cases where the results are ignored before the full processing of the returned rows is complete the close method **MUST** be called in order to release underlying resources.

The interface is minimal in order to support all SQL clients not just JDBC.

7.  def close(handler: Handler[AsyncResult[Unit]]): Unit

   Closes the stream/underlying cursor(s).

   Closes the stream/underlying cursor(s). The actual close happens asynchronously.

   handler

     called when the stream/underlying cursor(s) is(are) closed

8.  def close(): Unit

   Closes the stream/underlying cursor(s).

   Closes the stream/underlying cursor(s). The actual close happens asynchronously.

9.  def closeFuture(): Future[Unit]

   Like close but returns a scala.concurrent.Future instead of taking an AsyncResultHandler.

10.  def column(name: String): Int

    Will convert the column name to the json array index.

    Will convert the column name to the json array index.

    name

      the column name

    returns

      the json array index

11.  def endHandler(arg0: Handler[Unit]): ReadStream[JsonArray]

    Set an end handler.

    Set an end handler. Once the stream has ended, and there is no more data to be read, this handler will be called.
