Appending 300 tables into 1 table

[jean paul levahn]

I need to append 300 tables (same columns, possible diff formats) onto 1 in Access.

All the tables start with the same name.

I used to have a piece of code that i ran that would simply pull all tables into 1 but have since lost it.

I have to be honest and say i have no VB skills what so ever and i think this is the only way this could be done quickly.

Hi what do you mean by diff formats?

How many coloumns are there and what are the formats?

1. longwinded way would be to create a union query of 300 tables. But this would be view only.. data can only be added to original tables.

2. a.we can store all the table Names into a temporary Table
b. Read the contents of each table
c. Append to new table usng SQL

Pref Method

"Hi what do you mean by diff formats?" What I mean by this is that the excel sheets have different formats in the columns. But they all should be text columns.

I would prefer to use method 2 as i have to do this for several lots of data.

What do i need to put in the module?

Here is some example code, you will need to modify as appropriate.

Public Sub CreateAndAppend()
    'Create table
        Dim tblDef As DAO.TableDef
        Set tblDef = CurrentDb.CreateTableDef("tempTable", , , CurrentProject.Connection)

        With tblDef
            .Fields.Append .CreateField("KEY_Hazard", dbLong)
            .Fields.Append .CreateField("mem_Title", dbMemo)
            .Fields.Append .CreateField("ID_CreatedBy", dbLong)
            .Fields.Append .CreateField("dt_Created", dbDate)
        End With

        CurrentDb.TableDefs.Append tblDef

    'Cleanup
        Set tblDef = Nothing
    Dim oTbl As Object
    For Each oTbl In CurrentData.AllTables
        If Left(oTbl.Name, 5) = "excel" Then
            DoCmd.SetWarnings (False)
            DoCmd.RunSQL "INSERT INTO tempTable ( KEY_Hazard, mem_Title, ID_CreatedBy, dt_Created )" & _
                " SELECT [Hazard ID], Title, User, Date " & _
                " FROM [" & oTbl.Name & "]"
            DoCmd.SetWarnings (True)
        End If
    Next
    
    'cleanup
        Set oTbl = Nothing
End Sub

You write that all your tables start with the same letters, in this example I append all tables called "excel..... " to the first table I create.
