Question

I have a query that I wish to initially call to catch all results from a database.

Then, when a combobox is updated, I wish for it to catch the columns only WHERE column = SelectedItemFromComboBox.

It’s all done; the only thing I am missing is some way to query

SELECT *
FROM Table1
WHERE Column1 = ALL;

So that I can then update it to

SELECT *
FROM Table1
WHERE Column1 = SelectedItemFromComboBox;

What can I initially set the string for SelectedItemFromComboBoxto so that I return all values?

Thanks.

Set SelectedItemFromComboBox to null and change your query to

SELECT *
FROM Table1
WHERE Column1 = SelectedItemFromComboBox
or SelectedItemFromComboBox is null
