Search behavior issue with dates.

Search behavior issue with dates.

I have added a search behavior to a set of WADB pages. The saledate field is set to = as the comparison operator.

The problem is I want to be able to search for sales on a day, but record the day and time of the sale. The field is already a day and time field. How can I use WADB to search for records recorded on a day out of a date-time field?

Is there an easy way to do thisother than setting up a between date 1 and date 2 form fields which would still have to be date time fields or if they both were the same day, it would come out 2013-03-25 00:00:00 to 2013-03-25 00:00:00.

in the recordset for the results page, you would need to use the MySQL DATE_FORMAT() function to return the date formatted as only the Y-m-d portion.

for example:
SELECT *, DATE_FORMAT(dateColumn, "%Y-%m-%d") as formatedDate FROM tblName

then in the Database Search criteria for the date search, use the formatedDate aliased column

Nice solution. I'll give that a try.

Nice thought, but it doesn't work. Unknown column 'formatedDate' in 'where clause'

This works:

SELECT *, DATE_FORMAT(dateColumn, "%Y-%m-%d") as formatedDate FROM tblName WHERE DATE_FORMAT(dateColumn, "%Y-%m-%d") = [search date]

but I don't know how I could get WADB to do that.

I think, without making it completely custom, that my choices are to either do a search for from dateY to dateY, or add a column that holds only the date.

Even the first scenario requires tweaking the code as WADB will add the date column twice, but gives the form input the same name.

It would be nice if the GUI had some better options for searching date columns. Consider that a feature request.

I see, I always forget that you cant use an aliased column in the WHERE clause.

After running the Data Assist Search wizard, you would need to edit the comparison code to add the date format

for example, the comparison may look like this:


php:
$WADbSearch1->addComparisonFromEdit("DateColumn")","dateField","AND","=",0);



you would add the date format option like this:

php:
$WADbSearch1->addComparisonFromEdit("DATE_FORMAT(DateColumn,\"%Y-%m-%d\")","dateField","AND","=",0);

Thanks., That is helpful. I already made a from x date to y date range search function. I'll share how I did that later, but this will also be useful in the future.
