ACC: How to Import Several dBASE Databases at Once (1.x/2.0) (88764)

SUMMARY

This article explains how you can import dBASE databases in a batch process by using Access Basic.

Many new Microsoft Access users want to import data immediately from the systems they are currently using. The Import dialog box in Microsoft Access enables you to import one table at a time, which usually is sufficient. However, if you have numerous tables to import, or if you want to import multiple tables regularly, this process enables you to do so more quickly.

This article assumes that you are familiar with Access Basic and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Access Basic, please refer to the "Introduction to Programming" manual in Microsoft Access version 1.x, or the "Building Applications" manual, Chapter 3, "Introducing Access Basic" in version 2.0.

MORE INFORMATION

This process uses an Access Basic procedure and a batch table. The procedure is designed for importing only dBASE databases, but you can modified it to accommodate other file formats.

The batch table lists the tables that you want to import. The Access Basic procedure reads the table and imports each foreign table listed there. To create the table and the Access Basic procedure, follow these steps:

Create a table called Batch Import with the following structure:

      Field name         Type   Length
      --------------------------------
      Source Directory   Text   50
      Source Database    Text   50
      Imported Name      Text   50
      Type of Table      Text   50

Enter information in the new Batch Import table about the tables you want to import. You should fill out the fields in the Batch Import table as follows:
- Source Directory: This is the full path for the location of the foreign database file (for example, C:\DBASE).
- Source Database: This is the name and extension of the dBASE database you want to import (for example, CUSTOMER.DBF).
- Imported Name: This is the name you want the table to have after it is imported into Microsoft Access (for example, Customers).
- Table Type: This can be either dBASE III or dBASE IV. Specify dBASE III for both dBASE III and dBASE III PLUS databases.
For example, to import a dBASE IV database called EMPLOYEE.DBF from the C:\DBASE4 directory and a dBASE III database called ORDERS.DBF from the D:\DBASE3\DATA directory, fill out the fields in the Batch Import table as follows:
```
      Source Directory   Source Database  Imported Name   Table Type
      --------------------------------------------------------------
      C:\DBASE4          EMPLOYEE.DBF     Employee Table  dBASE IV
      D:\DBASE3\DATA     ORDERS.DBF       Orders Table    dBASE III
					
```

Create a new module, and type the following code.

NOTE: In the following example, an underscore (_) at the end of a line is used as a line-continuation character. Remove the underscore from the end of the line when re-creating this example.

      Sub BatchImport ()
         Dim B_DB As Database, B_TBL As Table
         Set B_DB = CurrentDB()
         Set B_TBL = B_DB.OpenTable("Batch Import")

         DoCmd Hourglass True
         B_TBL.MoveFirst
         Do Until B_TBL.EOF
            DoCmd TransferDatabase A_IMPORT, B_TBL![Type of Table], _
             B_TBL![Source Directory], A_TABLE, B_TBL![Source Database], _
             B_TBL![Imported Name], False
            B_TBL.MoveNext
         Loop
         DoCmd Hourglass False
      End Sub

Import the foreign databases as follows:
1. Open a module.
2. From the View menu, choose Immediate Window.
3. Type the following command, and then press ENTER:
  
  BatchImport

The pointer will become an hourglass and remains so until all of your databases are imported. This process may take several minutes, depending on the sizes of the databases.
