That must be one big SQL statement. The BSTR does have a length limit. The characters in the BSTR are preceded by a 4 byte number indicating the length of the string. Since its a 2 byte / character Unicode string, the limit is the largest number that can be stored in 16 bits. Somewhere on the order of 65000 characters.
Maybe thats not the problem.
If you post some code, someone might be able to help.
Good luck,
Bill

I have a recodset that has been impoted from a csv text file. This is done via reading each line if the csv/text file into a sting procing the sting into an array and then add the values to the recordset.
So I end up with a nice recordset. Now I seem unable to sort the recordset so that it contins a list of distint names. (EG I want a list of of the printers in the recordset). normanly this can be done via sql with the command "select distinctrow field list from tablename" however as i've populated the recordset from a text file i do not know what the tablename is?
can anyone tell me how this is done or suggest another way? I'm programing this in vb6.0.
thank you

You didn't mention if you use SQLServer,access or vf so
How did you import them?(programmically)As I remember,when SQLServer import database you can
define table name.
Can't you set name manually if you use Access or SQLServer or..?

Thanks for responding, I am not connecting to any SQL server. I am just opening a text file and populating a recordset My code is below.
After I run this I am having trouble finding a way to just get a list of unique QueueName's from the recordset??
I create a recordset via this code....
Set rs = New Recordset
rs.CursorLocation = adUseClient
rs.Fields.Append "UserName", adBSTR, 128
rs.Fields.Append "DocName", adBSTR, 128
rs.Fields.Append "QueueName", adBSTR, 128
rs.Fields.Append "Date", adDBDate
rs.Fields.Append "Time", adDBTimeStamp
rs.Fields.Append "Workstation", adBSTR, 128
rs.Fields.Append "ClientCode", adBSTR, 128
rs.Fields.Append "Subcode", adBSTR, 128
rs.Fields.Append "PaperSize", adBSTR, 128
rs.Fields.Append "Features", adBSTR, 128
rs.Fields.Append "Sizeinbytes", adBSTR, 128
rs.Fields.Append "Pagecount", adBSTR, 128
rs.Fields.Append "cost", adBSTR, 128
rs.Fields.Append "AccountBalance", adBSTR, 128
rs.Open
Then I import the txt file into the recordset using this code...
Dim F As Long, sLine As String, A(0 To 13) As String
F = FreeFile
Open "C:\temp\text.txt" For Input As F
Do While Not EOF(F)
Line Input #F, sLine
ParseToArray sLine, A()
rs.AddNew
rs.Fields(0) = A(0)
rs.Fields(1) = A(1)
rs.Fields(2) = A(2)
rs.Fields(3) = CDate(A(3))
rs.Fields(4) = CDate(A(4))
rs.Fields(5) = A(5)
rs.Fields(6) = A(6)
rs.Fields(7) = A(7)
rs.Fields(8) = A(8)
rs.Fields(9) = A(9)
rs.Fields(10) = A(10)
rs.Fields(11) = A(11)
rs.Fields(12) = A(12)
rs.Fields(13) = A(13)
rs.Update
DoEvents
Loop
Close #F
End Sub
Sub ParseToArray(sLine As String, A() As String)
Dim P As Long, LastPos As Long, i As Long
P = InStr(sLine, ",")
Do While P
A(i) = Mid$(sLine, LastPos + 1, P - LastPos - 1)
LastPos = P
i = i + 1
P = InStr(LastPos + 1, sLine, ",", vbBinaryCompare)
Loop
A(i) = Mid$(sLine, LastPos + 1)
End Sub

I have a Access database running on Win ME with VC6.0
and I created a table (by hand in Access) then I try and
use my program to create a record in that table.
the code is executed but the record is not created and
no error messages are thrown. If there is a record already
in the table (again put in by hand) then additional records
can be added without any problems.
Any ideas on what may be wrong ?

I can't understand what is wrong there,but I have two suggestion,first
debug your code to see whats going on there,and second update your database
after you addnew ,also try this,may be this one is ok
hr = pRs->AddNew();
if( FAILED( hr ) ) throw _com_error( hr );--------->you'd better to put it in your code too
pRs->Fields->GetItem( L"fieldname1")->Value = anything1;
pRs->Fields->GetItem( L"fieldname2")->Value = anything2;
pRs->Fields->GetItem( L"fieldname3")->Value = anything3;
hr = pRs->Update();
if( FAILED( hr ) ) throw _com_error( hr );
Hope thats help you

One field of my database is Text(string).
Is there any SQL statement or ODBC function to find a word in text of
each recordsets and return recordsets contain that word?

I need convert a SqlBinary to an interger. What is the best way to do this?

We are using SQL Server 8, The column size is 1024 when
I try to insert a text that is longer than 255 it gets truncated.
This happens even when I try to insert directly into the table (using Query analyser), -usually we use ADO with VB 6-
I checked the database option to make sure the compatibility option is not set to 6.5, since that would make SQL 8 act
as SQL 6.5 which has a maximum varchar size of 255, and therefore truncates anything bigger.
Help
|
|
|
|
|
O.k I found the answer to this a while ago.
First it was not truncated. In Query analyzer the default max size of the results returned is 255.
Second our ADO module had a hard coded parameter that limited the use of any strings larger than 255.

The statement:
DELETE FROM License WHERE LicenseID = 4
Should surely delete all rows from the License table that have a LicenseID field equalling 4, but it is not affecting the table License in any way, despite indicating success. 
Any ideas? The Row with LicenseID equal to 4 (there is only one) is still there. It is executed on a Microsoft Access database, and the data type of LicenseID is (auto)number, if any of that helps.
After 3 hours my eyes are starting to bleed.

What is the result of doing:
SELECT * FROM License WHERE LicenseID = 4 ?
Are there any triggers on the table?
Do you get the same behaviour on other tables?
Cheers,
Simon

That returns, as expected, the row where the LicenseID is equal to 4. I know I must be doing something wrong, as I have managed to delete rows before. (Interestingly enough, I had this same problem before, and eventualyl found a solution, but i'll be damned if I can find where it is now).

As is said above, basically, you need to specify the columns to operate on as well (you could just delete data from certain columns, something I've never tried). Just bung a * after DELETE, as if you were doing a SELECT operation.
Also, I don't use spaces around '=' in SQL, I don't know if this is permitted or not, you might wanna check that out (presumably if you done it elsewhere it's fine).
The reason it's returning success is because you're not actually telling it to delete anything at all. Hope that helps.

That was the first thing I tried, but alas it makes no difference. The row/s are still not being deleted. 
Andrew Peace wrote:

I do when writing the statements in ASP/JScript, as it makes it easier to read with all the " + strVar + "'s floating around in there. It doesn't make any difference though if I remove the spaces.

That is what I had been suspect all along, though I can't understand why it could not be finding the rows.
Thanks for the suggestions though.

Did you find this problem? If not, I have an idea....
In Access at least, if you set relationships up between tables and use the Enforce Referential Integrity option, delete operations will not occur unless you deleted all related rows in other tables. You can avoid this problem using the 'Cascade' options which will make the changes for you.

I haven't fixed it, no, but what you've just said could be the problem... I'll check tomorrow as it's far to late/early to do anything about it tonight.
Thanks again.
