Expand all | Collapse all


If you try to change the length of a column inside BeginAlter and DoAlter like this:
Set column1 = t.Columns("city")
column1.Length = 70
this error message occurs:
-2147201020 (80045004):
[SQL-DMO]Modifying existing table columns, or inserting new ones prior to the end of the table, is not supported.


Use ExecuteImmediate to execute the ALTER TABLE ALTER COLUMN. For example:
Dim server1 As New SQLDMO.SQLServer
Dim db1 As SQLDMO.Database
server1.Connect "(local)", "sa", ""
Set db1 = server1.Databases("pubs")
db1.ExecuteImmediate ("Alter table publishers Alter column city varchar(50) ")
