When I run this code I get this error message "Syntax error in INSERT INTO statement". Can anyone explain why my command is a syntax error? Thanks.
rsGuest.Open("Guest", ADOConnection, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockOptimistic)<br />
Dim command As String<br />
<br />
<br />
command = "INSERT INTO Guest(Guest ID) VALUES('1111')"<br />
ADOConnection.Execute(command, rsGuest)

There are two possible reasons I can see.
Firstly, your syntax is wrong:
command = "INSERT INTO Guest(Guest ID) VALUES('1111')"<br />
Should be
command = "INSERT INTO Guest<big>[</big>Guest ID<big>]</big> VALUES('1111')"
Also, is [Guest ID] an identity (autonumber) column?

column name Guest ID is having space so it cannot be used directly
use it like this
command = "INSERT INTO Guest([Guest ID]) VALUES('1111')"

Sorry, thats what I meant - you need to put Guest ID in square brackets, I didn't mean to lose the () round it. Old age and failing eyesight to blame

Ok, I know vb.net and I've used ms access before and I understand the basic concepts of what a recordset and cursor and other stuff are but I have never used ADO before to program a database and I need to learn. Specifically I am trying to use vb.net 2005 to program ms access 2007.
I've opened the database and opened a recordset successfully. This is the code I used.
Private ADOConnection As New ADODB.Connection 'the database<br />
Private rsGuest As New ADODB.Recordset 'the recordset<br />
<br />
'code for opening the database and recordset<br />
ADOConnection.Open("provider=microsoft.ace.oledb.12.0;" & "Data Source=j:\junk.accdb")<br />
rsGuest.Open("Guest", ADOConnection, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockOptimistic)
What I need to know is what is the syntax for adding data to a recordset. If someone could give me an example it would be very helpfull. Thanks in advance.
Mike
ps I have googled the hell out of this but every example I find is either a different version of access or vb, or is an example of using sql server, or it is an example of vba within access. In any case there seem to subtle incompatabilities that mean the examples never seem to work.

You really shouldn't be using ADODB from VB.Net. ADODB is an older COM technology and was replaced in .Net with the System.Data.Oledb namespace classes. Oledb uses Datasets, Datatables, DataReaders and DataAdapters rather than Recordsets. It performs better than ADODB and is easier to use, and is an integrated set of managed classes.

End Sub
any help 
waiting for your kind rep.

after you delete row then close and open connection
conStudent.Close()<br />
conStudent.Open()

hello
first of all thanks for your rep.
i have tried it but it's not working

Perhaps pivot isn't what I'm looking for, but here's what I'm trying to accomplish (pardon the XML).
I have a table of species:
<TableDef IsPooled="false" Name="Species">
<Fields>
<TableFieldDef Length="0" DataType="Integer" IsPK="true" IsIdentity="true" Name="ID" />
<TableFieldDef Length="0" DataType="Integer" PKTable="Family" PKField="ID" Name="FamilyID" />
<TableFieldDef Length="50" Name="Name" />
<TableFieldDef Length="50" Name="CommonName" />
</Fields>
</TableDef>
and a table of samples:
<TableDef IsPooled="false" Name="Sample">
<Fields>
<TableFieldDef Length="0" DataType="Integer" IsPK="true" IsIdentity="true" Name="ID" />
<TableFieldDef Length="0" DataType="Date" Name="SampleDate" />
<TableFieldDef Length="0" DataType="Integer" PKTable="SamplingSite" PKField="ID" Name="SamplingSiteID" />
<TableFieldDef Length="0" DataType="Integer" PKTable="Species" PKField="ID" Name="SpeciesID" />
<TableFieldDef Length="16" AllowNull="true" Name="AbundanceRank" />
<TableFieldDef Length="16" AllowNull="true" Name="PercentCover" />
<TableFieldDef DefaultValue="false" Length="0" DataType="Boolean" Name="Present" />
</Fields>
</TableDef>
which references the sampling sites table:
<TableDef IsPooled="false" Name="SamplingSite">
<Fields>
<TableFieldDef Length="0" DataType="Integer" IsPK="true" IsIdentity="true" Name="ID" />
<TableFieldDef Length="0" DataType="Integer" PKTable="Location" PKField="ID" Name="LocationID" />
<TableFieldDef Length="0" DataType="Integer" PKTable="Subhabitat" PKField="ID" Name="SubhabitatID" />
<TableFieldDef Length="0" DataType="Integer" PKTable="GPSCoord" PKField="ID" Name="GPSID" />
<TableFieldDef Length="512" Name="Descr" />
</Fields>
</TableDef>
What I'd like is a vertical list of species crossed with a horizontal list of sampling sites in which, for each species at that sampling site, the percent cover is given (qualified by date or a master sample ID so we can guarantee that there's only sample per species-sample site, but that's not the question, I can figure that part out).
So, is this this species-sample matrix done with a pivot or some sort of cross apply?

You could do this using PIVOT but you would need to supply fixed/known columns (Sampling Sites). Dynamic cross-tabulation of data in the way that you require is handled by Analysis Services or by importing the data into Excel and using the pivot functions there.

Thanks for the reply. After researching the matter some more, I came to the same conclusion.
Funny thing is though, I'm constructing the data so that I can export the result to Excel.

I've got this query:
select
Species.Name as Species_Name,
Species.CommonName as CommonName,
Family.Name as Family_Name,
NativeView.NativeCode
from Species
left join NativeView on SpeciesID=Species.ID
inner join Family as Family on Species.FamilyID=Family.ID
That uses this view:
create view NativeView as
select
Species.ID as SpeciesID,
SpeciesNativeTypeOptionList.Code as NativeCode
from Species
inner join SpeciesTypeInfo as SpeciesNative on Species.ID = SpeciesNative.SpeciesID
inner join SpeciesTypeOptionList as SpeciesNativeTypeOptionList on SpeciesNative.SpeciesTypeOptionListID=SpeciesNativeTypeOptionList.ID
inner join SpeciesTypeList as SpeciesNativeTypeList on SpeciesNativeTypeOptionList.SpeciesTypeListID=SpeciesNativeTypeList.ID and SpeciesNativeTypeList.Name='Native'
But what I'd like to do is formulate the query without using a view at all.
The problem comes in on the "left join" above, because I want "NativeCode" to return null when the species ID does not have a matching row in the query that makes up the NativeView.
Is it possible to achieve that (get rid of the view)?
Thanks!

Here:
select
Species.Name as Species_Name,
Species.CommonName as CommonName,
Family.Name as Family_Name,
v.NativeCode
from Species
left join
(select
Species.ID as SpeciesID,
SpeciesNativeTypeOptionList.Code as NativeCode
from Species
inner join SpeciesTypeInfo as SpeciesNative on Species.ID = SpeciesNative.SpeciesID
inner join SpeciesTypeOptionList as SpeciesNativeTypeOptionList on SpeciesNative.SpeciesTypeOptionListID=SpeciesNativeTypeOptionList.ID
inner join SpeciesTypeList as SpeciesNativeTypeList on SpeciesNativeTypeOptionList.SpeciesTypeListID=SpeciesNativeTypeList.ID and
SpeciesNativeTypeList.Name='Native'
) v
on v.SpeciesID=Species.ID
inner join Family as Family on Species.FamilyID=Family.ID
The thing I was missing was the alias for the inner select. I've been learning that when SQL says there's an error with ')', it means I'm missing an alias name.

Values which you insert on first table insert and in second table too, same way use for update.

Hi all,
I made a very simple program to manipulate with DB as below
1. I have a SQL Server DB. The database contains just only 2 tables
1.1 TEST1(KEYCODE, SEIHIND, TEXT1, TEXT2, TEXT3), KEYCODE is primary key, auto increase
1.2 TEST2(TEXT1, TEXT2, TEXT3) no key
2. I make a new MDB by MS Access 2007 and created link table to these above SQL DB via ODBC(SQL Server driver)
3. My program uses DAO 3.6 to insert data to SQL via MS Access
3.1 The bussiness is to select data from TEST2 and insert to TEST1
3.2 SQL is like
INSERT INTO TEST1(SEIHIND, TEXT1,TEXT2,TEXT3) SELECT '1', TEXT1, TEXT2, TEXT3 FROM TEST2
4. To obtain above, i made a simple program like below:
Private Sub Command1_Click()
Dim defWsk As DAO.Workspace
Dim dbs As DAO.Database
Dim sqlStr As String
Set defWsk = DBEngine.Workspaces(0)
Set dbs = defWsk.OpenDatabase("F:\Tin\PQMC.MDB")
defWsk.BeginTrans
sqlStr = "INSERT INTO TEST1(SEIHIND, TEXT1,TEXT2,TEXT3) " & _
"SELECT '1', TEXT1, TEXT2, TEXT3 " & _
"FROM TEST2 "
Debug.Print sqlStr
dbs.Execute (sqlStr)
defWsk.CommitTrans
End Sub
5. Issue: The problem when execting above code is "data is not inserted to TEST1, TEST1 is blocked(I could not execute SELECT * FROM TEST1 in SQL Analyser)" When i close program, table is not locked(I could execute SELECT * FROM TEST1 in SQL Analyser)
Notes: I take above SQL and execute in SQL Analyser. it's OK
Anyone know how to solve this problem, please help me. Thank you very much for your support.
Tin Le,
