sqlquery_addScope theQueryA, "not completed"

end if

## Query database

sqlquery_retrieveAsRecords theQueryA, theRecordsA

put the result into theError

if theError is empty then

set the dgData of group "ToDo" to theRecordsA

end if

if theError is not empty then

answer "Error populating to-do items:" && theError & "."

end if

end uiPopulateToDos

Here is the meat of the uiPopulateToDos handler reworked to use the Scopes we just created. We add Scopes in order to provide the search filters that have been specified by the UI.

1) Are the to-do items linked to a project or person?

2) Is the user searching for a particular string in a to-do name?

3) Should completed to-do items be displayed?

When you use sqlquery_addScope to add a Scope you pass in the name of the Scope object and then any values that will replace the binding variable in the Scope objects 'conditions' string.

Tip: If you want to see the SQL query that the SQL Query object you just created will generate you can check the 'query' property. Try adding the following line right before sqlquery_retrieveAsRecords and you will see the query appear in the Message Box whenever the to-do list is populated.

put sqlquery_get(theQueryA, "query")

After updating the uiPopulateToDos handler you can test the UI. Make sure you have at least one project and one person create and that you have linked a to-do item to the person. Select a project or person.

Check the 'Hide Completed Items' checkbox.

Enter a search term for a string that appears in a to-do item name and press the return key.

And then enter a search string that doesn't appear in a to-do item name and press the return key.

You can even enter search strings that use AND or OR operators. sqlyoga_splitUserSearchString will break the string up so that the records with the string 'broken' or the string 'busted' are returned.
