how to use rollback . give me syntax please
|
|
|
|
|
you can get the from online help
however i'm pasting only syntax part from the same
ROLLBACK [ TRAN [ SACTION ]
[ transaction_name | @tran_name_variable
| savepoint_name | @savepoint_variable ] ]
Arguments:
transaction_name
Is the name assigned to the transaction on BEGIN TRANSACTION. transaction_name must conform to the rules for identifiers, but only the first 32 characters of the transaction name are used. When nesting transactions, transaction_name must be the name from the outermost BEGIN TRANSACTION statement.
@tran_name_variable
Is the name of a user-defined variable containing a valid transaction name. The variable must be declared with a char, varchar, nchar, or nvarchar data type.
savepoint_name
Is savepoint_name from a SAVE TRANSACTION statement. savepoint_name must conform to the rules for identifiers. Use savepoint_name when a conditional rollback should affect only part of the transaction.
@savepoint_variable
Is name of a user-defined variable containing a valid savepoint name. The variable must be declared with a char, varchar, nchar, or nvarchar data type.

how to generate automatic id like c001.c002;
|
|
|
|
|
In SQL Server generates serial numbers automatically if the column is 'Identity column'. however this is possible only for numeric data type.
in your case
SELECT max(cast(substring(id, 2, 3) as bigint)) + 1 FROM tableA
here ....
1. using substring extracting last three digits
2. converting the digits to numeric
3. getting max()
4. then incrementing by one.

Is it possible to use multiple Like statments within a SQL statement? I have a page where users can query data based on two fields. The user then has the option to export the results to excel, via a link. If the user does not select any criteria then the fields default to %. When I trie to run the SQL statement it doesnt seem to like the %. Please help!!
DocAttach_Summary_Excel.asp?HMO=%&Doc_Attach=%
<%
Response.ContentType = "application/vnd.ms-excel"
Dim THMO
Dim TDoc_Attach
THMO = request.querystring("HMO")
TDoc_Attach = request.querystring("Doc_Attach")
%>
<% set objconn=server.createobject("adodb.connection")
connpath="DBQ=" & server.mappath("/fpdb/ClaimMart_Access.mdb")
objconn.Open "DRIVER={Microsoft Access Driver (*.mdb)}; " & connpath
set objrs=objconn.execute("SELECT * FROM Tbl_DocAttached_Summary WHERE (HMO LIKE '" & THMO & "' AND DOC_ATTACHED_FLG LIKE '" & TDoc_Attach & "')")
%>

You have a hugh security risk in your code. You are passing though a query string value directly to the SQL statement without it being sanitised. If the query string should contain, say, an apostrophe then that will change the meaning of the SQL Statement. If after the apostrophe it contains other SQL text then it could completely change the SQL statement's meaning. I advise you to read about SQL Injection Attacks and tips on how to prevent them[^]

This is an internal website located on the companies intranet. I just created the website to make the data more available. With that being said, am I still at risk?

hello
i was creating relationship betwween 2 tables with different data types for the primarykeys of the two tables.
One primary key had data type int and the other primary key had data typevarchar. when i tried to create relationship between the two table, Sql Server gave the error that both the primary key data types are different and hence it didn't create the relationship.
so what i want to know is that does the data types of the primary keys have to be the same to create relationship between the tables???

If you want to create a relationship between two tables the type of the primary key on one table must match the foreign key on the other. The only time that two primary keys must match is when you are creating a one-to-one (or zero-to-one) join because the primary keys are also the foreign keys.

Yes.It should be same datatypes while creating a relationship between two tables.

The OP was asking about two PRIMARY KEYS. The primary keys do NOT have to be the same, and often they are not the same in two related tables. The important part is the PRIMARY KEY on the parent table matches the type of the FOREIGN KEY on the child table. You only need to match both primary keys when you are creating a one-to-one or zero-to-one relationship.

Are you sure that is what you want to do? It doesn't sound like a very useful relationship to me. What if two (or perhaps 11) boys play football?
Adding a unique constraint does not make a 1-to-1 relationship.
If you want to create a one-to-one relationship then generally both tables will share the same primary key (which also happens to be a foreign key to the other table too)

Well, it means that the table boys does not contain a column called sports_type.

Hi G. to the U.R.U.S.!
I have a table with the following fields
MessageID
MessageTitle
MessageText
I want to create an SP which allows me to:
1. add new message if there's no similar message on it
2. edit the message is theres existing message already.
Please advice
regards
Dom

It's hard to know which of the fields you are intending to define as the control. If you just want to base the check on the message title, then the following will suffice:
IF Exists (SELECT MessageID FROM Message
WHERE MessageTitle = @Title)
BEGIN
UPDATE Message SET MessageText = @MessageText WHERE MessageTitle = @Title
END
ELSE
BEGIN
INSERT INTO Message (MessageTitle, MessageText) VALUES
(@Title, @MessageText)
END
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before.

Hi John
Thanks for the help,
I tried the suggestion you've made but some weird thing comes up. I don't know where @message_id came from, I don't remember having it on the SP. any ideas?
Msg 201, Level 16, State 4, Procedure sp_altermessage, Line 0<br />
Procedure or Function 'sp_altermessage' expects parameter '@message_id', which was not supplied.<br />
|
|

|

OK - my names Pete not John. John's the name of somebody I've quoted. (Note to self, change sig).
Secondly, you need to declare @message_id.
CREATE PROCEDURE dbo.PostMessage
@Title NVARCHAR(50),
@MessageText NVARCHAR(200),
@message_id INT OUT
AS
SET NOCOUNT ON
IF Exists (SELECT @message_id = MessageID FROM Message WHERE MessageTitle = @Title)
BEGIN
UPDATE Message SET MessageText = @MessageText
WHERE MessageTitle = @Title
END
ELSE
BEGIN
INSERT INTO Message (MessageTitle, MessageText) VALUES (@Title, @MessageText)
SET @message_id = SCOPE_IDENTITY()
END
