Not really. The specification is that the object can be any category, contact, vendor, project, etc. So I need a table to track the data entered for each of these objects. Then the user will be able to link associated documents to these different objects. The key here we will never know the object that a user will come up with.

Hi Art

Have you heard of DDL (Data Definition Language)?  It is a subset of SQL, and so you can execute a DDL "query" in the same way you execute a normal SQL command to create and modify tables and other database objects.

Here is an article to get you started:
https://support.office.com/en-us/article/Create-or-modify-tables-or-indexes-by-using-a-data-definition-query-d935e129-229b-48d8-9f2d-1d4ee87f418e

I assume, since you say that the table and field names are "coming from a form", that they are actually stored in one or more tables.  Therefore, you can open a Recordset that returns the fields, one at a time, and loop through it creating your SQL/DDL string.  Something like this:

Set db = CurrentDb
Set rs = db.OpenRecordset( "your SELECT statement here" )
strDDL = "CREATE TABLE " & strTableName & "("
Do Until rs.EOF
    If rs.AbsolutePosition > 0 Then strDDL = strDDL & ", "
    strDDL = strDDL & rs!FieldName & " " & rs!FieldType
Next
strDDL = strDDL & ")"
CurrentDb.Execute strDDL, dbFailOnError

You can also add other qualifiers to each line, such as NOT NULL (i.e. Required), UNIQUE (i.e. No Duplicates), and PRIMARY KEY and other CONSTRAINTs.

Best wishes,
Graham

How can I create a table dynamically using VBA. I found the code to create the table but the gotcha is that the table name and fields names are coming from a form.I have a form called sfrmObjectTypeFields which contains the field names which I need to transfer into the VBA CREATE TABLE statement. Any ideas?

 

Thank you,
