Question : Word/Excel Mail Merge with variable worksheet name

I'm trying to write a subroutine in vba to add to Word for a mail merge.  The workbook name of the data source is always the same, but the worksheet name will be variable based on the date, for instance if I did it today, the sheet name I would use as the data source would be "110602" Getting the value of the variable won't be a problem, I can handle that OK. I recorded a macro to get an idea what Word does, but I don't know how to put a variable worksheet name in the procedure, in other words replace the literal. I also don't understand why the SQL statements are empty.  Of course, I want empty rows skipped.  Can I add something within to check a single field that I know should have data and if there is no data ("") then skip that record?
 Thanks!
(Here is the test macro I recorded:

ActiveDocument.MailMerge.OpenDataSource Name:= _
        "C:\Documents and Settings\My Documents\testing\testmerge.xls" _
        , ConfirmConversions:=False, ReadOnly:=False, LinkToSource:=True, _
        AddToRecentFiles:=False, PasswordDocument:="", PasswordTemplate:="", _
        WritePasswordDocument:="", WritePasswordTemplate:="", Revert:=False, _
        Format:=wdOpenFormatAuto, Connection:= _
        "Provider=Microsoft.Jet.OLEDB.4.0;Password="""";User ID=Admin;Data Source=C:\Documents and Settings\My Documents\testing\testmerge.xls;Mode=Read;Extended Properties=""HDR=YES;IMEX=1;"";Jet OLEDB:System database="""";Jet OLEDB:Registry Path="""";Jet OLED" _
        , SQLStatement:="SELECT * FROM `Sheet3$`", SQLStatement1:="", SubType:= _

Answer : Word/Excel Mail Merge with variable worksheet name

Here is what i get when recording macro: querying a XL workbook:
-source file is E:\Test Import.xls
-source data is named range NamedRangeName

SQL:
"SELECT Data.FieldName1, Data.FieldName2, Data.FieldName3 " & _
"FROM `E:\test import`.NamedRangeName Data " & _
"WHERE (Data.FieldName1 Is Not Null) ORDER BY Data.FieldName1 "

Replace
-FieldName1,2,3
-"E:\test import"
-NamedRangeName

Naming the range of data in XL could be a big help to the engine to
localise the data (and mainly data boundaries) in the SHeet.
