FS ZSQL Methods

  This document describes how to use FS ZSQL Methods. These are 
  Z SQL Methods that form part of filesystem-based skin layers.

  They behave identically to normal Z SQL Methods except that
  their parameters are specified in a comment block in the
  method's body. This comment block may appear anywhere, but
  it is recommended you place it at the top of the body.

  Here is a sample:
	
    <dtml-comment>
    Connection_id : my_db_connection
    arguments: arg1 arg2 arg3
    max_cache: 1000
    max_rows: 0
    cache_time: 0
    </dtml-comment>

    INSERT INTO
      mytable
    SET
      col1    = <dtml-sqlvar arg1 type=int>,
      col2    = <dtml-sqlvar arg2 type=string>,
      col3    = <dtml-sqlvar arg3 type=int>

    <dtml-var sql_delimiter>

    SELECT LAST_INSERT_ID() as NEWID
  
  The following list describes how the parameters in the
  comment block map to the properties of a ZSQL Method:

    FS ZSQL Method  Z SQL Method
    title           Title
    connection_id   Connection Id
    arguments       Arguments
    max_rows        Maximum rows to retrieve 
    max_cache       Maximum results to cache 
    cache_time      Maximum time (sec) to cache 

  You cannot control the class used for the data records
  with FS ZSQL Methods.

  For further details, please see the documentation for
  Z SQL Methods.
