Union Query - Create Additional Field / Clear Records

The code pasted below creates a union query for a set of tables (J000171, J000174, J000178 etc) and stores the results of the query in a table called temp.

The first piece of code queries the ‘status’ field of a table rjobs for those records with a ‘status’ field of “Live”. Another field within this rjobs table, ‘JobID’, happens to be the name of a table where additional information relating to that job record is held eg. J000178 All of the tables selected in the query on rjobs are then included in the union query.

The second piece of code stores this information in a table called temp

I would like to be able to do 2 things with this;

1.add an additional field to the union query which holds the JobID field value from rjobs (or alternatively the table name from which the data originates eg J000178 etc as that is the same as the JobID file din rjobs)

2.create an option to clear the info in the temp table. Currently additional info is appended, so whenever the query is refreshed new data is simply added to old data. I would like to be able to clear that data where possible.

The union query is run from the on click of a command button on a simple form. Perhaps an additional button could be used to clear the records from the table temp.

Any ideas greatly appreciated.

Here is the existing code …

Option Compare Database
Option Explicit


Private Sub Command0_Click()
Dim db As Database
Dim rsRjobs As Recordset
Dim rsRapps As Recordset
Dim LengthofUnionSQL As Long
Dim sql As String
Dim UnionSQL As String
Set db = CurrentDb
Set rsRjobs = db.OpenRecordset("Select * from rjobs where Status = 'Live'", dbOpenSnapshot)
Do While Not rsRjobs.EOF
UnionSQL = UnionSQL & "Select ObjectID, SearchNo, DateSearched, Consultant, from " & rsRjobs!jobID & " Union "
rsRjobs.MoveNext
Loop
'following two lines are to remove the trailing word Union from the string unionsql
LengthofUnionSQL = Len(UnionSQL)
UnionSQL = Mid(UnionSQL, 1, LengthofUnionSQL - 7)
' Now variable Unionsql will hold the value something like
' Select ObjectID, SearchNo, DateSearched, Consultant from J000145
' Union Select ObjectID, SearchNo, DateSearched, Consultant from J000146
' Union Select ObjectID, SearchNo, DateSearched, Consultant from J000147
MsgBox UnionSQL


Set db = CurrentDb
Dim rsUnionquery As Recordset
Dim rstemp As Recordset
Set rstemp = db.OpenRecordset("temp", dbOpenDynaset, dbSeeChanges)
Set rsUnionquery = db.OpenRecordset(UnionSQL)
Do While Not rsUnionquery.EOF
rstemp.AddNew
rstemp!ObjectID = rsUnionquery!ObjectID
rstemp!SearchNo = rsUnionquery!SearchNo
rstemp!DateSearched = rsUnionquery!DateSearched
rstemp!Consultant = rsUnionquery!Consultant
rstemp!jobID = rsUnionquery!jobID

rstemp.Update
rsUnionquery.MoveNext
Loop

End Sub
