I have been pulling my hair trying to figure out what the guys at microsoft were thinking when creating the ADOX library. I have an access table that is syncronized with a SQL server. The table has a primary key with two columns [User] and [Program]. The SQL Server has both columns in as the primary key columns and I have a syncronization mechanism that is responsible for several things, one of which is to recreate the Access data structure. All works well for all tables except this one. I have tried to create the multi-column key in several ways, none that worked. Let me show you what I am doing:
I need to programatically create a mdb file which will contain nullable columns. I am using C++ with ADOX for the table creation and ADO to perform the table update.
Although ADOX seems to create the table ok, Table->Columns->Appends does not set the fields as adColNullable as expected.
When I insert data using ADO::Recordset->AddNew the following error occurs :- "The field 'MyTable.Column 2' cannot contain a Null value because the Required property for this field is set to True. Enter a value in this field."
Am I on the right tracks here or do I need to adopt a different approach?
We€™re calling ADOX::Table::Keys::Append to make a primary key for a table using the SQLOLEDB provider. We€™re passing an ADOX::Key with Name set to a custom name, Type set to ADOX::adKeyPrimary, and a single column added. For the Append call, the 2nd parameter is ADOX::adKeyPrimary, the third is a vtMissing (VT_ERROR with DISP_E_PARAMNOTFOUND), the last two are empty BSTR€™s. On XP, this works well (msadox.dll file version 2.81.1117.0). On Vista, this fails with an invalid parameter error (msadox.dll version 6.0.6000.16386). Has the interface changed in some way, is this functionality not supported, or is it broken?
I'm using ADOX 2.8 for table creation: The following is an example of a column defintion:
If CreateNewTable Then CreateNewTable = a.CreateColumn("ReferenceCount", ADOX.DataTypeEnum.adInteger)
If CreateNewTable Then CreateNewTable = a.CreateColumn("Document", ADOX.DataTypeEnum.adLongVarBinary) 'Oleobject
If CreateNewTable Then CreateNewTable = a.CreateColumn("EntityID", ADOX.DataTypeEnum.adWChar, 18) 'text
Where CreateColumn looks like this:
Public Function CreateColumn(ByVal ColumnName As String, ByVal Datatype As ADOX.DataTypeEnum, Optional ByVal Size As Integer = 0) As Boolean
'ADOX.CreateColumn - Called by Common.CreateNewTable 'CreateColumn creates a column described in the Table object so it assumes it is set. 'One method of setting it is to call Select Table after opening the database
If Not Me.ConnectionIsOpen Then MsgBox("CreateColumn - Failed to Create Column : " _ & ColumnName, MsgBoxStyle.Exclamation, cNoConn) Return False End If
Dim col As New ADOX.Column col.Name = ColumnName Try col.Type = Datatype Catch e As Exception MsgBox("CreateColumb - Failed to Create Column : " _ & ColumnName, MsgBoxStyle.Exclamation, e.Message) col = Nothing Return False End Try
If Size <> 0 Then col.DefinedSize = Size Try
Table.Columns.Append(ColumnName, Datatype)
Catch e As Exception If Err.Number() <> 0 Then MsgBox(Err.Source & "-->" & Err.Description, , "Error") End If MsgBox("CreateColumb - Failed to Append Column : " _ & ColumnName, MsgBoxStyle.Exclamation, e.Message) Return False End Try col = Nothing Return True End Function
in CreateColumn("EntityID", ADOX.DataTypeEnum.adWChar, 18)
the 18 specifies the field width in the database. Yet no matter whether I use adWChar or
adVarWChar, Access always shows the field size to be 255.
I am using ADOX to create linked tables in a jet database from an ODBC datasource. The tables in the ODBC data source does not have a primary key. so I am only able to create read only linked tables.But I want to update the records also. I tried adding a primary key column to the linked table while creating the link. but I am getting an error while adding the table to the catalog.
The error message is "Invalid Argument".
I use the following code for creating the linked table
Sub CreateLinkedTable(ByVal strTargetDB As String, ByVal strProviderString As String, ByVal strSourceTbl As String, ByVal strLinkTblName As String)
Dim catDB As ADOX.Catalog Dim tblLink As ADOX._Table
' Name the new Table and set its ParentCatalog property ' to the open Catalog to allow access to the Properties ' collection. .Name = strLinkTblName .ParentCatalog = catDB
' Set the properties to create the link. Dim adoxPro As ADOX.Property
The first line of code works fine but when I try to set the value of the property I get the following excpetion:
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in MyDll.dll Additional information: Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
For example,I have a table "authors" with a column "author_name",and it has three value "Anne Ringer,Ann Dull,Johnson White".Here I want to create a new table by using a select sentence,its columns come from the values of the column "author_name".
can you tell me how can I complete this with the SQL?
Hi all, I am not over familiar with SQL, I am a VB programmer, simply I need to achieve the following within Enterprise Manager.
I have 2 tables, different designs, different number of rows, I simply need to check whether the contents of a column in the first table is in a column in the second table, just simply a table/column to table/column data check for the same data content.
Easy Peasy for you guys, any help would be appreciated.
I want to use time series algorithm to mine data from my case table and nested table. Case table is Date table, while nested table is the fact table. E.g, I want to predict the monthly sales amount for different region (I have region table related to the fact table), how can I achieve this?
Thanks a lot and I hope it is clear for your help and I am looking forward to hearing from you shortly.
I am confused on key column of case table and key time column of nested table by using Time Series algorithm.
In my case, the case table structure is as below:
Territory key text (the ID is actually dimrisk_key, in this case, I use the name column binding to combine the Territory column of case table Dimrisks),
While the nested table structure is as below:
Cal_month key time (in this case, actually the ID is dimdate_key, again, I used name column bining property to bind the Cal_month to the ID)
So my question is, as the key column of case table has been set to be Territory, as a result, does the model training still cover all the cases (rows) based on the ID of the table?
Also, in the nested table, as the key time column has been set to Cal_month rather than Dimdate_key of the nested table, as a result, would the single series based on the cal_month?
Hope it is clear for your advices and help.
And I am looking forward to hearing from you shortly.
Hi guys, If I have a temporary table called #CTE With the columns [Account] [Name] [RowID Table Level] [RowID Data Level] and I need to change the column type for the columns: [RowID Table Level] [RowID Data Level] to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time. What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE ALTER COLUMN [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
Hi I’m trying to alter a table and delete a column I get the following error. The object 'DF__Morningst__LastU__19EB91BA' is dependent on column 'LastUpdated'. ALTER TABLE DROP COLUMN LastUpdated failed because one or more objects access this column. I tried deleting the concerned constraint. But the next time I get the same error with a different constraint name. I want to find out if I can dynamically check the constraint name and delete it and then drop the column. Can anyone help.IF EXISTS(SELECT 1FROM sysobjects,syscolumnsWHERE sysobjects.id = syscolumns.idAND sysobjects.name = TablenameAND syscolumns.name = column name)BEGIN EXECUTE ('ALTER TABLE tablename DROP CONSTRAINT DF__SecurityM__DsegL__08C105B8')EXECUTE ('ALTER TABLE tablenameDrop column columnname)ENDGO

I simply need the ability using SQL to add columns in an existing table before (or after) columns that already exist.
The MS SQL implementation of ALTER TABLE doesn't seem to provide the before or after placement criteria I require. How is this done in MS SQL using SQL or is there a stored procedure I can use?
Hello everyone, I am new to ERWIN and I need helps from the experts outthere.We are using ERWin 4.1.2771 and have reversed engineered some MS SQLServer 2000 databases.The problem we are having is that we have a FK on a column to a tablewhere the PK of the referencing table is on another column (such as anidentity column). We have a unique index on the column in the PK tableand SQL Server allows you to build a FK reference even though thecolumn is not defined as the PK.Does anyone know how to create this type of FK within Erwin?Thank You
