    Filtering by DateTime field in VBA and SQL

    G'day, I am looking to upsize an Access app moving the backend to SQL Server. I am having issues with two areas at the moment.

    I want an SQL query that displays records created today, I have been using this with the Access backend:
    Code:
    SELECT tblAudit_Trail.AuditTrailID, tblAudit_Trail.DateTime, tblAudit_Trail.UserID, qryStaff.[Full Name], tblAudit_Trail.FormName, tblAudit_Trail.Stream, tblAudit_Trail.ParentRecord, tblAudit_Trail.RecordID, tblAudit_Trail.FieldName, tblAudit_Trail.OldValue, tblAudit_Trail.NewValue, tblAudit_Trail.ActionTakenFROM tblAudit_Trail LEFT JOIN qryStaff ON tblAudit_Trail.UserID = qryStaff.ID
    WHERE (((tblAudit_Trail.DateTime)>"Date()-1"))
    ORDER BY tblAudit_Trail.DateTime DESC;
    But I get and "Internal Error" if I try to use the Date() function.

    In addition, I have a search function that uses the following:
    Code:
    strWhere = "[DateTime] BETWEEN #" & Format(.txtFromDate.Value - 1, "mm/dd/yyyy") & "# And #" & Format(.txtToDate.Value + 1, "mm/dd/yyyy") & "#"
    This returns an error of "Search Key was not found in any records". I can't find anything to provide guidance on how to fix these issues.



    The SQL does work if I hard code dates in and the SQL Server data types are datetime.

    Thanks

    You would not have quotes around the date() -1 ?

    Debug.Print strWhere
    You are not showing all the code, so I hope that is within a With Me block?

    Thanks for responding Welshgasman.

    Removing the quotes around the date() -1 I get a type mismatch error.

    With the Where statement, I apply that as a filter to a recordset.

    What SQL driver are you using? Open the linked SQL table in design view in Access and confirm that the data type shows as Date\Time.

    Assuming your date time field contains times then Date()-1 will give you yesterdays records as well

    are you running this as an access query or a pass through query? If the latter then date() won’t be recognised. Check out the sql server getdate function

    if it is a pass-through query executed on SQL server the WHERE clause :

    Where Mydate >= dateadd(day, -1 ,cast(getdate() as date) )

    gives all records from yesterday and today

    Where MyDate >= cast(getdate() as date)

    gives all records entered today
