Jul 19, 2007
Hi Everybody,
I want to add new column 'firstaname' into the existing table "geo" already two columns namely

here is the snippet of code what i am using.
/* FieldsPtr fields;
FieldPtr field;*/
_bstr_t name("firstname1");
//pRstTitles->get_Fields(&fields);
/* pRstTitles->Fields->Append(name, adVarChar , 15, adFldUnspecified);
pRstTitles->CursorLocation = adUseClient ;
pRstTitles->LockType = adLockOptimistic ;
pRstTitles->Open("geo",
_variant_t((IDispatch *)pConnection,true), adOpenStatic,
adLockOptimistic, adCmdTable);*/
pls pls pls help me out .. I need it very urgently.

Hi all,
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:
CatalogClass catDCDLocal;
Column c;
catDCDLocal = new CatalogClass();
catDCDLocal.let_ActiveConnection(dbAccess.buildConnectionString(Settings.CattDCDLocalPath, Settings.SecurityDBPath, s.UserID, s.Password));
foreach (Table tbl in catDCDLocal.Tables) {
if (tbl.Name == "Users") {
/* This is retarded so need to clean up... Users table has a primary key consisting of 2 columns */
for (int i = tbl.Keys.Count - 1; i >= 0; i--) { //remove the keys
tbl.Keys.Delete(i);
}
for (int i = tbl.Indexes.Count - 1; i >= 0; i--) { //remove the indexes
tbl.Indexes.Delete(i);
}
tbl.Keys.Append("PrimaryKey", KeyTypeEnum.adKeyUnique, "User", "", "");
tbl.Keys[0].Columns.Append("Program", DataTypeEnum.adWChar, 6);
}
}
I have also tried:
tbl.Keys.Append("PrimaryKey", KeyTypeEnum.adKeyUnique, "User", "", "");
//tbl.Keys[0].Columns.Append("Program", DataTypeEnum.adWChar, 6);
Key k = tbl.Keys[0];
Column col = tbl.Columns["Program"];
//col.ParentCatalog = catDCDLocal;
k.Columns.Append(col, DataTypeEnum.adWChar, 6);
Nothing works for me ;-(

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?
Code block to illustrate the problem :-

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 need to rename tables in code VB2005 (access database). On the
forum I found post about ADOX and this code to rename the tables:
Private Sub RenameTables(ByVal sTextToRemove As String)
Dim i As Integer
Dim dbRename As Database
Dim Connect As New PrivDBEngine
dbRename = Connect.OpenDatabase(tbDBPath.Text)
dbRename.CreateTableDef()
For i = 0 To dbRename.TableDefs.Count - 1
If dbRename.TableDefs(i).Name.Length >= sTextToRemove.Length - 1 Then
If dbRename.TableDefs(i).Name.Substring(0, 9) = sTextToRemove Then
dbRename.TableDefs(i).Name = dbRename.TableDefs(i).Name.Substring(9)
End If
End If
Next i
dbRename.Close()
dbRename = Nothing
MessageBox.Show("Tables in " + tbDBPath.Text + " have been renamed.
Rename Access Tables", MessageBoxButtons.OK, MessageBoxIcon.Information)
End Sub
But it doesn't work because i get an error on Dim dbRename As Database Dim Connect As New PrivDBEngine
What I need to do for this to work?
Thank you!

but i got a invalid type error. I cannot understand.
why adox can not append adUnsignedBigInt field ?
Somebody can give me a answer? Thanks.

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.
Does anyone know why or how to fix that?

Hai,
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
Dim ADOConnection As New ADODB.Connection
ADOConnection.Open("Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & strTargetDB & ";User Id=admin;Password=;")
catDB = New ADOX.Catalog
catDB.ActiveConnection = ADOConnection
tblLink = New ADOX.Table
With tblLink
' 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
adoxPro = .Properties("Jet OLEDB:Create Link")
adoxPro.Value = True
adoxPro = .Properties("Jet OLEDB:Link Provider String")
adoxPro.Value = strProviderString
adoxPro = .Properties("Jet OLEDB:Remote Table Name")
adoxPro.Value = strSourceTbl
End With
'Adding primary key,
'***** the source column name is "Code" ******
tblLink.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "Code")
'Append the table to the Tables collection.
'******The exception occurs on the following line***********
catDB.Tables.Append(tblLink)
'Append the primary index to table.
catDB = Nothing
End Sub
If I avoid the line for adding the primary key,everything works fine,but the table ctreated is readonly.
Thanks in advance

Hi
I'm trying to add columns to an existing table using ADOX. I'm using C++/CLI. My code is as follow
Table->default->Append("new_column", ADOX:: DataTypeEnum::adWChar, 255);
Table->default["prev_instance_id"]->Properties["Jet OLEDB:Compressed UNICODE Strings"]->default = true;
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.
Any idea?

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.

Hi, all experts here,
Thanks for your kind attention.
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.
With best regards,

Hi, all experts here,
Thank you very much for your kind attention.
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.
With best regards,
Yours sincerely,

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 am trying to exclude records from a table where the ID column is the same but the Mail code Column is multi-valued.For Example: (the table looks like....)
ID Mail_code
111111 XNT
111111 N11
111111 XNC
222222 XNC
222222 XNL
333333 XNC
So, if there is any ID that has a value of XNC, I want to exclude the ID all together from my output regardless of the other values.

A column of a table has values in the format - 35106;#Grandbouche-Cropp, Amy.
I need to format the column data in such a way that only the text after # (Grandbouche-Cropp, Amy) remain in the column.
The text before ;# (35106) should be inserted in to another column of the same table.
Below is the table structure:

Remark that combination logtime/unitID is the natural key in unitLog.
"ID" is the surrugate key.
What is wrong here...?

Table structure as follows
Employee
Empno empname salary
commission
I want to have an other employee table named employee_modified
Empno empname salary
commission derived_column1(salary+commission)
derived_column2(derived_column1 + xxxx) and so on derive other
columns based on the earlier derived columns)
Is that possible to do it.. or am I doing something wrong.
something like
Select empno , empname , salary , commission,
(salary + commission) as derived_colum1 ,
(derived_colum1 + xxxxx) as derived_colum2 ,
(derived_colum2 + xxxxx) as derived_colum3
into employee_modified from employee

When you use "Alter Table add Column", it adds the column to the end of the list of fields.
How do you insert the new column to position number 2 for instance given that you may have more than 2 columns?
Create table T1 ( a varchar(20), b varchar(20), c varchar(20))
Alter table add column x varchar(20)
so that the resulting table is
T1 a varchar(20), x varchar(20), b varchar(20), c varchar(20)
Can this be done programmatically?

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?
Thanks.

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
