I want to use an sql select statement as the row source for a combo box..
- When I set the row source type to 3-SQL and enter the row source as "select space distinct from map into cursor T1" attempting to run the form results in "Program error Unrecognized command verb" - If I set the row source type to 2-Alias and the row source to T1 and put the SQL select statement into the init method of the control the Combo box populates properly.
I would have expected that the system would be smart enough to run the SQl statement before trying to use it's output. Is there something else I need to call perhaps in the form init method?
Thanks in advance,
Joe

Hi Joe,
Those settings are working for me in my quick test. Does the SQL statement you have in the RowSource work in code?
As a test I built a cursor with the days of the week in it in the Load event of a form. CREATE CURSOR ComboBoxData (id i, displaytext c(30)) I set the ComboBox.RowSource to select displaytext from comboboxdata into cursor t1 and set the ComboBox.RowSourceType = 3 && SQL statement
To be consistent with your select statement I added the "distinct" clause and it still works.
I tested in VFP 9 SP2 Hotfix 3
HTH, Tracy

Tracy,
I did another test form using days of the week like yours. I still got the error. Then I removed the quotes around the CSL statement and it worked! Somewhere in my surfing I had read that the quotes were required but that is apparently incorrect.
More details:
1. When does the SQL get executed? When it is first loaded? Each time the control gets focus? When requiry is called? 2. Are all cursors created this way in scope for the entire VFP system? 3. Is there a simple way to see the VFP code generated by the Form Designer to understand how it works?
Thanks so much,
Joe

My data is in a table called labels with three fields, space, location, and label. I thought my problems were solved but now when I setup my second combo box with the row source set to
select location distinct from labels where labels.space = thisform.combo1.value = labels.space into cursor T2 I get the message "Thisform can only be used within a method"
When I set the row source to
select location distinct from labels where labels.space =combo1.value = labels.space into cursor T2 I get the message "Ali8as Combo1 is not found."
When I put the SQL code in the load or init methods of the form it works without error so the code is okay Is there a different syntax needed here or do I need to handle this in a different way?
Thanks,
Joe

Combobox1 selects into a cursor. Use that cursor name in the where clause of the select statement in combobox2. In the valid event of combobox1, call the requery method of combobox2. The initial queries are processed after the form load event. They only requery when told to.

I know you're all probably tired of hearing this drumbeat, but having SQL statements in UI controls is a bad idea. Do what you can to separate that out.

I admit, I prefer to not use the UI controls that way. I also admit that I'm an enabler, and if people want to use the controls that way I help. I should probably start adding something like: You could do it that way, though it may not be as maintainable if you did X.

Hi Joe,
don't put in quotes or double quotes the sql statement!
