Create MDB database using ASP/VBScript:

There are two ways to create MDB database using VBScript.

1. Create MDB by ADO (ADOX):

The following code is for creating a new Access2000 database by ADO and for the code to execute MDAC2.0 is required to be installed in the machine.


const jet4x = 5

DoCreateNewMDB "F:\MyAccessDB2000.MDB", Jet4x

Sub DoCreateNewMDB(FileName, Format)

Dim Catalog

Set Catalog = CreateObject("ADOX.Catalog")

Catalog.Create "Provider=Microsoft.Jet.OLEDB.4.0;" & _

"Jet OLEDB:Engine Type=" & Format & _

";Data Source=" & FileName

End Sub

Compact (compress) MDB database using ASP/VBS script.

We can compact MDB database directly from the ASP (VBS) by DAO or JRO.

1. Compact MDB by DAO Engine:

The following code need DAO 3.5 to be installed in machine.

Dim Engine

Engine.CompactDatabase "F:\Database.mdb", "F:\Compacted_Database.mdb"

Set Engine = CreateObject("DAO.DBEngine.35")


2.Compact MDB by JRO Engine:

The following code need MDAC 2.1 to be installed in machine.

Dim Engine

Set Engine = CreateObject("JRO.JetEngine")

Engine.CompactDatabase "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=F:\Database.mdb", _ "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=F:\Compacted_Database.mdb"

Neither DAO nor JRO allow you to compress and replace existing file on the fly. So we need to create a temporary compacted database and then copy the temporary file over the original database"

Convert MDB database to another format(JET,access conversion) using ASP/VBScript:

We can convert the MDB database to another format by using the following VB script.

Let's assume F:\MyDB97.MDB is the source database which needs to be converted to the database F:\MyDB2000.MDB

const jet4x = 5

DoConvertMDB "F:\MyDB97.MDB", "F:\MyDB2000.MDB", Jet4x

Sub DoConvertMDB(SourceDB, DestDB, Format)

Dim Engine

Set Engine = CreateObject("JRO.JetEngine")

Engine.CompactDatabase "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & SourceDB, _

"Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Engine Type=" & Format & ";Data Source=" & DestDB

End Sub
