Hi
I need to upload binary file (dll) to SQL Server database throught ADO.
I tried to use "ADODB.Stream" object, but i can't open this stream from the file.
hVecoStream->Open(n, adModeUnknown, adOpenStreamUnspecified, _bstr_t(""), _bstr_t(""));
hVecoStream->LoadFromFile(szFileName);
Could you specify correct syntax for this method call
Thanx.

please answer either on board or on bin_omair@usa.net

Well, if both the databases are SQL-Servers I would use the Data Transfer or the Replication in SQL Server.
To get a better answer, you'll need to be more specific, in what it is you want...

I'm having major problems using nested outer joins with
SQL Server 6.5 and ODBC.
I'm following the documentation to the letter but I'm getting
the error "The column prefix '' does not match with
a table name of alias used in the query"
I do not get errors when using Oracle.
Does anyone have an example of nested outer joins?
Many thanks.

I think they had limits on the nesting. What does the Oracle query look like?

I am running a large links database at http://www.scoutinglinks.com so record paging is a must.
My problem is that many of my users are still using Netscape 4.x. These user can view the first page with out problems, if they select a link the next page they receive "the parameter is incorrect" error message. I have confirmed the error through testing, the reports are accurate.
I have rewritten the function numerous times, the last method I found here at The Code Project "http://www.codeproject.com/asp/rspaging.asp" with the same result.
If anyone has ever experienced this and found a solution your suggestions would be appreciated. I have asked these users to upgrade to Netscape v 6, but we all know how that goes. I have also tried finding a Java solution but really don't want to rewrite the whole app.
Again, any help would be appreciated.
Regards
Bert

Kind all,
I built this MTS object that runs a SP and should be able to returns to the user:
'1) (if existing) the Rs(s) found for the wanted DB table(s);
'2) the adParamOutput, adParamReturnValue ADODB.Parameters
from the SP.
When I run the component the following things happen:
* the adParamOutput and the adParamReturnValue ARE EMPTY
(note that I forced the SP to return in any case a Return value and a value as output paramter).
** when I loop the array that should comntain all the RS(s) contained in a specific DB field, I get
the usual "Subscript out of range".
I poste my code: both the code (DBObj.cls) for the DB object and the code (.frm) I used x testing it.
The name of the DLL project is: OggettoDB.

I am trying to append record to the newly created Database(which is created thro' DAO ) thro' program . But, i am unable to add the first record(thro' ADO).But if I add the first record manually(directly into the DB)the following records are getting appended thro' program perfectly.
How can I append the first record thro' the program .

Hi
I wonder if MS-SQL use some hashing table when i create
atable in which the key is a string(URL)
if no,do you think that by using hashing function on each string
and stroing the result(from the hashing function)
in the data base will increase searching performance...?
(the result is a numeric value)
thanks

No I think it is a waste of clock pulses. Unless the information will not change once entered and only new unique rows are entered, otherwise I say why add clock pulses to the parsing of the string. Speed is the goal so KISS is the answer.

Hi there all,
Well i'm trying to figure out a way to lock a record while working with an .mdb file (Access 2000).
When i try to set CRecordset::SetLockingMode(CRecordset::pessimistic) the system will throw an error saying "not supported locking mode" - IS THIS AN ODBC DRIVER PROBLEM OR ACCESS DB ?
So ... I tried to find a way to know if there is a way to find when is the record editted (from outside the program since 2 processes are running at the same time) and couldn't - Does somone have an idea of how to FIND OUT IF A RECORD IS EDITTED BY ANOTHE APP. ?
Thanks alot for the help i would apritiate it alot,
Ariel.

I get an IDispatch error #3092 when I execute a stored proc that does a rather basic insert into a Sybase SQL Anywhere database. I have reviewed the stored proc more than a dozen times, but cannot find anything wrong with it.
Where can I find the real meaning of such errors. Does anyone have an idea of what could be happening. I have posted the stored proc below. Error lookup does not give the correct result.
Create Procedure PersonAdd
(
@EntCode varchar(3),
@Accd varchar(3),
@FirstName varchar(40),
@MiddleName varchar(40),
@LastName varchar(40),
@Suffix varchar(15),
@Title varchar(25),
@PrevName varchar(35),
@Alias varchar(35),
@SSN varchar(11),
@BirthDate datetime,
@Sex varchar(6),
@IDTypeCode varchar(10),
@IDNo varchar(15),
@IDState varchar(15),
@TaxID varchar(11),
@EthnicCode varchar(10),
@RaceCode varchar(10)
)
AS
INSERT INTO Person
(EntCode,
Accd,
FirstName,
MiddleName,
LastName,
Suffix,
Title,
PrevName,
Alias,
SSN,
BirthDate,
Sex,
IDTypeCode,

@Accd,
@FirstName,
@MiddleName,

@Suffix,
@Title,
@PrevName,
@Alias,
@SSN,
@BirthDate,
@Sex,
@IDTypeCode,
@IDNo,
@IDState,
@TaxID,
@EthnicCode,
@RaceCode,
GetDate(),
user_name())
DECLARE @PersonID INT
SELECT @PersonID = @@IDENTITY
RETURN (@PersonID)
GO

Try executing this from SqlAdvantage to see what it returns. What is @@IDENTITY ? Is it an int or some other data type?
|
|
|
|
|
Does anyone have an idea of how you can retrieve/return the value of a primary key (IDENTITY/Autoincrement COL) value after an INSERT statement using ODBC or ADO (without a stored proc). I am not using a stored proc, and so cannot use the @@IDENTITY function. I am using Sybase SQL Anywhere and MS SQL Server 7 as my databases.
Any suggestions or code samples would be appreciated.
|
|
|
|
|
Just after the statement that execute the INSERT.
eg:
SQL = "your insert statement"
set rs=mycon.execute(SQL)
'assuming that your identity field name is Key1
response.write("New key: " & rs("Key1"))
hope this works for ya
|
|
|
|
|
select @@identity as ID should do the trick.
Then ID = rs("ID")
cheers,
Chris Maunder
|
|
|
|
|
idCMD = New OleDb.OleDbCommand("SELECT @@IDENTITY", Me.conn)
Should work with any database that supports an indentity column.

I'm trying to show the headers of all the records in a listbox :
1. is there a easiest/better fitted control for showing headers of records ?
2. whats my next step for loading a dialog with all Record Data after a row had been selected ? How do i get the index of the Record (is there a return value in ListBox ??) or, How to retrive the Record from the ListBox ?
Thanks for your help,
Ariel.

Hi there,
Well i'm trying to figure out a way to lock a record when i'm editting it and it seems i can't find the way.
First, I'm using ODBC and my DB is both in Access and FoxPro - i'm not sure wether the lock of the record is handled by ODBC Drivers or the DB itself - so if somone can help me with that i'll be more than happy.
Second, I'm trying to change the CRecordset::SetLockingMode(CRecordset::pessimistic) and i get an exception which tells me i'm actualy back to default CRecordset::Optimistic (Locking Mode) - those this have to do with my ODBC Driver or my Access DB.
Third, is there a flag in CRecordset which tells me whether the Record is edited by another user or only the ODBC/DB (???) handles and know it ?
Actually what i'm asking in a one sentence is : Can i check if a record is edited by another user in another process or i have to put my own Semaphore for this ???
Thank you alot for reading all this and much more if help given,
Ariel.

Record locking is handled by the database engine itself...
