to_sql_extended

Description:

public string to_sql_extended (Connection? cnc, Set? @params, StatementSqlFlag flags, out SList<unowned Holder>? params_used) throws Error

Renders this as an SQL statement, with some control on how it is rendered.

If cnc is not null, then the rendered SQL will better be suited to be used by cnc ( in particular it may include some SQL tweaks and/or proprietary extensions specific to the database engine used by cnc): in this case the result is similar to calling statement_to_sql.

Parameters:

this	a Statement object
cnc	a Connection object, or null
flags	a set of flags to control the rendering
params_used	a place to store the list of actual Holder objects in `params` used to do the rendering, or null
params	parameters contained in a single Set object, or null

Returns:

a new string if no error occurred
