ADODB.Recordset to new access table same fields names, types and size

Hi there

i would like to create a function that create a table in (Access database) with the same fields name/type/size of the ADODB.Recordset that i passed to the function.

Also if the table is exists, then we need to check all the fields are exists too with the same types, otherwise update the table to match the recordset

the function will look something like that

Public Function NewRSTable(rs As ADODB.Recordset, cn ad ADODB.Connection, Optional OutputTableName As String) as Boolean
if database in cn is not exist
    create empty database using same cn path
else
   1- check if OutputTableName table exist - match all fileds with the rs otherwise, update the table definition to match the RS (or we can simply delete the table and re-create it again)
   2- create a new table using same field name/type/size in the recordset
end if

return yes/no and why not

i hope you understand what i mean

kind regards,
Mohamed

The ADO Field object would give you everything needed. The Field.Type would tell you the datatype and Field.DefinedSize would tell you the Length, in the case of Text field.

To add fields, you'd first add a Table, then append Fields to that Table:

Dim tdf As DAO.TableDef
Set tdfNew = CurrentDB.CreateTableDef("YourTableName")
tdf.Fields.Append tdf.CreateField(fld.Name, fld.Type, fld.DefinedSize)

I'm not sure if the ADO Field.Type will translate over to the DAO Field.Type, but you can give it a shot.

Note this does not create indexes, primary keys, or anything of that sort. This would just create a table with columns of a specific data type.

Why not just copy the table, then clear it out?

'Copy the table to a new table based on he names in two textboxes
DoCmd.CopyObject , Me.txtNewTableName, acTable, Me.txtTableName
'Clear all the records from the new table.
CurrentDb.Execute "DELETE * FROM " & txtNewTableName, dbFailOnError

Thank you for your feedback

RS contains data from different tables and i want this function to be re-useable for different tools

thanks

That's a pretty big request on a volunteer help forum ...

You can create a database using several methods. One is via the DAO.CreateDatabase method:

DAO.CreateDatabase "Full path to the db" , dbLangGeneral, dbVersion120

Here: https://msdn.microsoft.com/en-us/library/office/ff835033%28v=office.15%29.aspx

You can check whether it exists by using DIR. After parsing it from the Connection:

If Dir("YourPath") <> "" Then
  '/ it exists
Else
  '/ it does not exist
End If

To create the table, you'd have to loop through the Fields collection of the Recordset:

Dim fld As ADODB.Field
For each fld in rst.Fields
  '/ add the column to a table
Next fld

Hi Scott McDaniel,

thank you for your reply
how can we add fields to the new table to be similar (name/type/size) to fields in recordset
I am expecting the code to read the fields definitions in recordset and create same field definitions into the new table
I am able to loop in the RS fields and get the fields names. but to get the types it returns different types like "string" instead of "text". and i am not sure about the other types

Thanks
