You are welcome.
Upon reading my answer again, I actually got the values the wrong way round!
You would normally have the DisplayMember = "Description" and the ValueMember = "ID".

MS ACCESS HELP Listing -> "If the DataType property is set to Text, enter a number from 0 to 255. "
Anybody know how to deal whit this, to make it higher than 255?
Or maybe how to set Memo type at least?
Regards!

Access' text datatype (Varchar in oledb terms) is limited to 255 characters (unicode).
the 'memo' field type (LongVarChar) holds up to 63,999 characters.
You set the field datatype when you create the table. Some databases allow the type to be changed
with "Alter table". There are restrictions on what changes can be made whithout losing data, not sure what access supports.

It's obvious;)
Rob Graham wrote: There are restrictions on what changes can be made whithout losing data
There is no data in table, and the goal is, how to set the memo datatype?
There is no option to choose memo, so how to do it?
Aby ideas?

In the Table Designer, next to the Field Name is a Data Type column. Click in it, and you will have a drop down arrow on the right side. Click it, and choose Memo. It's obvious.

Yeah I know it's obvious;P
But..., the problem was with translation (in mine Access "memo" is as a "note") used in Access. Datatype's name in any way points to memo datatype for me. So, I was confused, but now I konow. 
Thanks

Hi guys,
Heres my problem, i created a stored procedure that takes a person's ID number as a parameter
and says if the id number is Valid or Invalid. So basically after it has done the necessary calculation, i just state at the end to get an output:
If @CalcID = @ControlDigit
Select 'Valid'
Else
Select 'IN-Valid'
Now, in another sql script, i have a select statement to get all members, display the fields i need where where the members id's are invalid, basically like this :
Select Name,Email,Phone
from Members
Where ValidateIDNum Members.IDNum = 'IN-Valid'
ValidateIDNum is the procedure i stated above.
but kept getting errors, complaining about incorrect syntax near ValidateIDNum
Is this the right way, to do this type of work, also i tried the same work around using functions but still to no avail.
please help.
Thank You In Advance.

Why not do it without the function
Select Name,Email,Phone
from Members
Where Members.IDNum = @ControlDigit
only two letters away from being an asset
|
|
|
|
|
well i dont think that will work,
because, the control digit is calculated from the ID Number by a twenty step process, and this calculation should equal the last digit of the ID Number.
I want to break this process up, since we will probably be using it alot.
Im just trying to change the whole thing without procedures and with a cursor loop.

Use a function, and put parenthesis around the parameters you are sending in.
Select Name,Email,Phone
from Members
Where ValidateIDNum<code><big>(</big></code>Members.IDNum<code><big>)</big></code> = 'IN-Valid'

SQL Trigger not working on update statement
hi
i am having a table with 3 columns (a,b,c).
i have written a trigger for INSERT / UPDATE as c=a+b
this is working fine as long as i enter/update each row by row manually.
but, when i use any update statement for a set of rows, the trigger is firing only for the last row.
can anyone please help?
Thanks
|
|
|
|

Do you know that if an Update statement affects multiple rows, the trigger fires only once, and in the trigger you have to select from the virtual tables INSERTED and DELETED to get the copies of the affected rows.

If the 'c' column is only a calculation of a+b, why not just use ([a] + [b]) as a formula?
Anyway, you could also use INSTEAD OF triggers:
CREATE TRIGGER InsteadUpdateTrigger on tblTable
INSTEAD OF UPDATE
AS
BEGIN
UPDATE tblTable
SET a=i.a,b=i.b,c=i.a+i.b
FROM INSERTED i
WHERE tblTable.IDField = i.IDField
END
CREATE TRIGGER InsteadInsertTrigger on tblTable
INSTEAD OF INSERT
AS
BEGIN
INSERT INTO tblTable
SELECT a,b,a+b
FROM INSERTED
END

Is there a reason for not using a VIEW on this table? The table would have columns a and b. The view would have columns a, b, and c where c is defined as (a+b).

Or, just give the c field a formula of ([a] + [b]):
CREATE TABLE [tblTable] (
[IDField] [int] IDENTITY (1, 1) NOT NULL ,
[a] [int] NULL ,
[b] [int] NULL ,
<code>[c] AS ([a] + [b]) </code>,
CONSTRAINT [PK_tblIDField] PRIMARY KEY CLUSTERED
(
[IDField]
) ON [PRIMARY]
) ON [PRIMARY]

I have been programming an application with VC++ 2005 and SQL Server 2005. I have converted an old 16-bit database for 32-bit managed code and SQL server and the application seems to be good. Now I want to deploy the application to another server for testing.
I have installed XP SP2, Windows Installer 3.1, Net framework 2.0 and SQL Server 2005 express to the test server. I have transferred the application with WI 3.1 and the program works well in the test server till the first SQL command. I have made a back up of the database and restored in the test server. In the test server I can log in the database with Server Management studio and I can read the data there correctly. I have enabled both named pipes and TCP/IP for the database in the test server. With Surface Area Configuration I have enabled Local and Remote Connections Using both TCP/IP and named pipes. I only need Windows authentication at this time.
After all this when I come to the first SQL command in the application on the test server I receive the error message:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server).
My connection string to the database is:
'connection->ConnectionString = "Persist Security Info=False; Integrated Security =SSPI;"
"Data Source=TESTSERVER; Initial Catalog=TESTDATABASE;";'
When I use "Data Source=DevelopmentServer", the application works well on the development server.
Can't understand what is still wrong. Can anyone possibly have an answer?

Finally found the solution as there was an error in the command string. In SQLExpress server the data source must be presented in format SERVER\SQLExpress. When this is part of the above C++ command string it must have the format
"Data Source=TESTSERVER\\SQLExpress; Initial Catalog=TESTDATABASE;";
although the backslash is within quotation marks.

If suppose we have to add a row in a table, using insert and there is a primary key(PKID) which is auto incremented.
After executing the SP how will we know that what being the value of that key, i.e. to retrieve it from the SP itself,
i had heard that there is a particular command for that
Can someone help me plz................
|
|

|

If you want to get the PKID(auto incremented) then you can use @@IDENTITY for that. This will give you the PKID of just inserted recored.

I didn't get your reply and what I soppose that you fine mine question unclear
So let me clarify it
I am asking that Suppose there is an SP that store some information Inserted by user and it generate automatically an ID (identity element) for that particular information.
Now after calling this SP in some of the function I want the PKID that is assigned to recent information, How can I retrive this PKID ??
