Default Compare only the date portion of a datetime field

Experts,
I need to extract the date portion of a datetime column .

Sample SQL
---------
Select
"Project Sub ID",
"Staff Name",
"Status Reporting Date"


From
"Status"

Where
"Project Sub ID" = '1451291 Purge/Archival Processing' and
"Staff Name" = 'Pradhan, Ismail' and
"Status Reporting Date" = '04/15/2005'.

The "Status Reporting Date" is a datetime field , so it is stored as '04/15/2005 14:55:56".
In the above compare it does not match because it is comparing '04/15/2005 14:55:56" with '04/15/2005 00:00:00'.

Is there some built in function in Access I can apply to my SQL to get to only the date part of the "Status Reporting Date" field ?

Appreciate your help.

Thanks

Use format to remove the time part

Note:Dont forget to use the CDATE to convert back to date if you have to use logical opertors

EG: CDate(Format([Status Reporting Date],"mm/dd/yyyy")) = = '04/15/2005'.

Parshant,
I tried your example and it did not work. I get a "syntax error in query expression" message.
Here is what I tried :
Select
"Project Id" as project_id,
"Project Sub Id" as project_sub_id,
"Staff Name" as staff_name,
"Status Reporting Date" as reporting_dt,
CDate( Format(["Status Reporting Date"],"mm/dd/yyyy") ) = '04/15/2005' ;

From
status ;

I am running this query against Microsoft Access 2002.
Also, I tried the quesry with "= = " also ( 2 equal signs ) , that did not work too. I thought the 2 equal signs was a Java thing.

I did a serach in Access help for CDATE and it came up completely blank.
I removed CDate and tried and got the same error

Select
"Project Id" as project_id,
"Project Sub Id" as project_sub_id,
"Staff Name" as staff_name,
"Status Reporting Date" as reporting_dt,
Format(["Status Reporting Date"],"mm/dd/yyyy") = '04/15/2005' ;

From
status ;

Can you see what I am doing wrong ?
Appreciate your help

Parshant,
I also tried it this way
Select
"Project Id" as project_id,
"Project Sub Id" as project_sub_id,
"Staff Name" as staff_name,
"Status Reporting Date" as reporting_dt,
Format(["Status Reporting Date"],"mm/dd/yyyy") = #04/15/2005# ;

From
status;

I thought I needed the "#" for the date , but still no luck.
Thanks

The syntax you were given was for the WHERE clause, not the SELECT clause.

You need to name the field when you create a formated field in the SELECT part of your query like:

Format([Status Reporting Date],"mm/dd/yyyy") as reporting_dt

For your WHERE clause use either:

Format([Status Reporting Date],"mm/dd/yyyy") = "04/15/2005"

Or:

CDate(Format([Status Reporting Date],"mm/dd/yyyy")) = #04/15/2005#
