How to create relationship in VBA?

[Tran Hong Quang]

Hi,
Could someone give me a code sample to create a one-to-
many relationship between 2 tables?

you can look at example for Relation Object or CreateRelation Method section
of online help:

Set relNew = .CreateRelation("EmployeesDepartments", _
tdfNew.Name, tdfEmployees.Name, _

dbRelationUpdateCascade)

 

[Allen Browne]

Sub CreateRelationDAO()
Dim db As DAO.Database
Dim rel As DAO.Relation
Dim fld As DAO.Field

'Initialize
Set db = CurrentDb()

'Create a new relation.
Set rel = db.CreateRelation("tblDaoContractortblDaoBooking")

'Define its properties.
With rel
'Specify the primary table.
.Table = "tblDaoContractor"
'Specify the related table.
.ForeignTable = "tblDaoBooking"
'Specify attributes for cascading updates and deletes.
.Attributes = dbRelationUpdateCascade + dbRelationDeleteCascade

'Add the fields to the relation.
'Field name in primary table.
Set fld = .CreateField("ContractorID")
'Field name in related table.
fld.ForeignName = "ContractorID"
'Append the field.
.Fields.Append fld

'Repeat for other fields if a multi-field relation.

End With

'Save the newly defined relation to the Relations collection.
db.Relations.Append rel

'Clean up
Set fld = Nothing
Set rel = Nothing
Set db = Nothing
Debug.Print "Relation created."
End Sub

There is a DDL solution in m.p.a.tablesdbdesign.

By the way, if you think you have to ask a question in more than one NG,
please use crossposting (sending one message to all the groups) rather than
multiposting (sending separate messages to each one) because it saves
everybody time.
