Subject [jira] Commented: (CAY-1287) SQLTemplate for not-mapping (DataRow) queries
Date Fri, 02 Oct 2009 11:33:24 GMT

    [ https://issues.apache.org/jira/browse/CAY-1287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12761548#action_12761548

Evgeny Ryabitskiy commented on CAY-1287:
----------------------------------------

But it's also very confusing to developer course he don't know which Map to Use and User Guide
have nothing about it.... We should write about it there!

I have simple solution for it.. At least it's not confusing to new developer.... :

// new constructor using only DataNode
public SQLTemplate(DataNode dataNode, String defaultTemplate) {
     //use any DomainMap course there is no metter...
     this(dataNode.getDomainMaps.iterator().next(), defaultTemplate);
}

> I wish to use nice SQLTemplate scripting engine for my simple not-mapping (DataRow) runtime-formed
queries.
> But now I should pass a DataObject to SQLTemplate constructor.
> The question is: "For what?"
> To do mapping???
> If my query is like: "SELECT max(id) as MAX_ID from Table1" it has no sense!
> I want to add constructor like: SQLTemplate(String defaultTemplate, Map parameter)
> and teach DataContext to perform such queries well.
