Selecting records between two dates

[trackmanpete]

I am getting an error using the following script generated via Action Scripting.
The error is "invalid filter expression".
Using file that contains consecutive dates from November 1, 2008 until March 1, 2009, I am hoping to select records of seven days beginning with a prompted date (varialbe vdates). I used the Action script Prompt for Date to create the variable. Thus, vdates="December 8, 2008" as an example. I then used the query "between dates" to try and select records that begin with vdates (Dec 8) and vdates+7 (Dec 14). I tried the formula date()+7 in the Code editor and got the correct result. So, I am confused as to why the Action Script generates an error. Here is the script generated by Action Scripting:

dim prmpt_title as c 
dim prmpt_default as c 

prmpt_title = "Select Beginning Date"
prmpt_default = ""
	
vdates = ui_get_date_calendar(prmpt_title,prmpt_default)

'Opens the default Form or Browse layout, displaying all, or selected records in the layout.
query.filter = "between(Datenumber,Var->vdates,Var->vdates+7)"
query.order = "recno()"
'replace variables in the filter with their actual values	
query.filter = convert_expression(query.filter,"V")

'Open the default Form showing just the records that satisfy the filter
DIM Shared varP_layout as P
DIM enable_show_all as l 
'The enable_show_all flag turns makes the Show-All button on the form toolbar gray.
'This means that the user cannot turn off the base query for the form.
enable_show_all = .f.   
varP_layout =  a5_open_default_Form("day",query.filter,query.order,"Temporary Query","",enable_show_all)

Thanks for looking

Re: Selecting records between two dates

What's the data type for "Datenumber"?

ui_get_dates_calendar() returns a CHARACTER data type result.

Might there be a data type mismatch between Datenumber and vdates?

Re: Selecting records between two dates

Hi Tom:
Datenumber is D as is vdate.

Interesting, as I closed the database and then opened it again and now the selection is partially working. The query picks the correct first date, but does not pick the correct second date (first date + 7). Instead I am getting 14 days.
the ui_get_dates_calendar() is a new one for me, so I will take a look at that.

Oh well, I will keep working on this. Thanks for looking....

Update: Ok, I got it to work properly. I had to use +6 from first date. Kind of dumb on my part, thinking first date + 7 is equal to a week... Too many late nights....

I'd be interested in seeing the working script. Thanks.

Re: Selecting records between two dates

Yes, my Action Script coding does work with one caveat. When I try to do a week selection (today plus six days), the first time I try it, the code does not work. I have to use a different date than today. Once I have chosen a different date, which works, I can then go back to running the code using today's date.

Thanks for your code submission. It will take me some time to see how it would work. I am able to get the two calendars, but have to figure out how to connect to my file.

Thanks again for your interest.

[djldc]

Re: Selecting records between two dates

Pete,
You might want to try setting the date variables to todays date after you dim them... that is, after:
DIM SHARED vSingleDate as D
vSingleDate = Date()
and..
DIM SHARED vWeek as D
vWeek = Date()


Just a thought.

Don

[trackmanpete]

Re: Selecting records between two dates

Don:
Thanks for the suggestion. I tried it and it seems to work. I will find out for sure tomorrow when the date changes. Since I tried to strictly use Action Scripting, the opportunity to create the vDate=Date() doesn't seem to exist. I did go in and change the Action Script to xbasic and implemented your code suggestion.

Thanks again.

[djldc]

Re: Selecting records between two dates

Pete,
You're right.. I thought you were using xbasic code. If you want to stick strictly with action scripting, I think you can still set a "default value" by checking that box and setting that value as Date().

Don

[trackmanpete]

Re: Selecting records between two dates

Thanks, I got that to work also. I forgot about the default setting (actually I did not realize that is what it was for). One more question before I overuse your kind suggestions:
Rather than use your two calendars as the start point and end point for selecting between dates, I am presently using a fixed 6 days:

IF a5_eval_expression("=Var->vdate=\"Week\"") THEN 
'Save a report, label, letter, form or browse to an Acrobat, Rich Text, HTML or Plain Text file. You can specify which records to save.

query.filter = "between(Day->Datenumber,Var->vweek,Var->vweek+6)"
query.order = "Day->Datenumber"
'replace variables in the filter with their actual values	
query.filter = convert_expression(query.filter,"V")

What I would like to do is create another variable that would replace the
"6" with whatever number I want to add from the beginning date.
I tried using Action Script's "Prompt for a number", but got an error message saying the variable was not correct. I thought that the variable should be a number, since the six is a number and when added to the initial date, comes up with the end date. So, I dim vnofdays as N. Then I tried it by dimming nnofdays as C. Also no luck. Any idea of what I might be going wrong with my thinking.

When I used the Action Scripting for "Prompt for number" I got the following code:

dim prmpt_title as c 
dim prmpt_prompt as c 
dim prmpt_default as c 

prmpt_title = "Select # of Days to Print"
prmpt_prompt = ""
prmpt_default = "6"

DIM SHARED vnodays AS C
	
vnodays = ui_get_number(prmpt_title,prmpt_prompt,prmpt_default)
	

query.filter = "between(Day->Datenumber,Var->vweek,Var->vweek+Var->nofdays)"
query.order = "Day->Datenumber"
'replace variables in the filter with their actual values	
query.filter = convert_expression(query.filter,"V")

What confuses me is why when I prompt for a number the code creates a variable that is a character and not a number. The end result is I get an error message no matter what I try and do.

[djldc]

Re: Selecting records between two dates

Pete,
I looked it over very quickly and saw that you are dimming:
"dim prmpt_default as c" as a character...

did you want that to be a number:

"dim prmpt_default as N"

If that doesn't work let me know and I'll give it a closer look. It's my pleasure to help.. It's also my turn to give back a little.

Don
LATER:
OK.. didn't work... let me take a closer look and I'll get back to you.

[Stan Mathews]

Re: Selecting records between two dates

ui_get_number() returns a character string. Use val() to get a numeric result.

Doesn't matter how you dim the variable.

[djldc]

Re: Selecting records between two dates

Pete,
Another thought.. replace this with yours (I change this: val(Var->nofdays))

query.filter = "between(Day->Datenumber,Var->vweek,Var->vweek+ val(Var->nofdays))"

If that doesn't work could you supply the full script in it's entirty?

Don

[trackmanpete]

Re: Selecting records between two dates

Using Action Scripting, this is what finally worked:

'Create an XDialog dialog box to prompt for parameters.
DIM SHARED vnodays as N
DIM SHARED varC_result as C
vnodays = 6
ok_button_label = "&OK"
cancel_button_label = "&Cancel"
varC_result = ui_dlg_box("Select # of days to Print",<<%dlg%
{region}
| [%z;s1,31%.40vnodays];
{endregion};
{line=1,0};
{region}
<*15=ok_button_label!OK> <15=cancel_button_label!CANCEL>
{endregion};
%dlg%)

	
	

query.filter = "between(Day->Datenumber,Var->vweek,Var->vweek+vnodays)"

query.order = "Day->Datenumber"
'replace variables in the filter with their actual values	
query.filter = convert_expression(query.filter,"V")

Seems as if the Action Script for "Prompt for Number" doesn't work correctly.
