I have a form that submits to multiple tables. After insertion into the first table I need to access the identity key from the record and use is to associate a record in another table. The form element I'm inserting into the second table however, is not a required field so I think I need to check IS NOT NULL first. In my code below I have copied the insert statement for the first table and the conditional and subsequent insert into the 2nd table. I am uncertain where and how I get and use @@identity. The error I'm getting when I run the Check Syntax button is: 'incorrect syntax near @@identity.'I appreciate someone telling me how to correct my syntax. INSERT INTO GPRA_Activities(SubmitDate,StaffId,GPRAId,FreedomID,DocumentDesc,ActivityTitle,ActivityDesc)VALUES (getDate(),@StaffId,@GPRAId,@FreedomID,@DocumentDesc,@ActivityTitle,@ActivityDescSELECT @@identity )if @KeywordId1 IS NOT NULL @@identity smallint, INSERT INTO GPRA_KeywordsUsed ( ActivityId, KeywordId ) VALUES ( @@identity, @KeywordId1 )GO
View 6 Replies View RelatedI have a demo database in SqlCE that I am getting ready to deploy. I deleted a bunch of test records and now want to reset the identity columns. The compact method runs fine, but the identity columns are not being reset? So when I add a new record, the returned identity value is over 1,000 even though the highest value is only 50.
Any help is greatly appreciated!

Anyone can help? Thanks a lot.
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,
Barkingdog
I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
* I can't change anything on T
* The PK is NOT an Identity

I am trying to implement a band search on my web site (concert listings) and would like it to behave a bit more intelligently than a standard match on the band name.
At the moment I have a stored procedure that just selects every show that features a band with exactly the same name as the search term. What I'm now trying to do is when the user enters a band name containing the '&' character I would also like to search using the word and 'and'. For example, if they search for 'Rise & Fall', they should get details on all shows featuring 'Rise & Fall' OR 'Rise And Fall'. Is it possible to do this within my stored procedure?
Greetings, I am a php developer, and running a little bit out of deadline in a project. Can someone provide me with a VERY simple way to implement search by keyword in C#? I have already implemented a search page (according to firstname, lastname etc) that works on a drop down menu (where you have the option to choose seach by keyword) . So, I need to change something in my SQL query to make this work. I already knew from my SQL experience that the simplest and probably the SLOWEST and MOST UN EFFICIENT one was using LIKE. I don't mind using it but I can't since I will end up having something close to that: SELECT * FROM users WHERE keyword_entered LIKE @keyword; (or '@keyword) which does not work. however SELECT * FROM users WHERE keyword_entered LIKE 'somename%'; does work! I guess the trick is in putting the % after the keyword. ( I would have done that in php by putting the entered keyword in a string and than add to it % and pass it to the SQL query and I dunno how to do that in .NET)any ideas?
View 7 Replies View RelatedHi everyone,
I have a few classes representing my data layer for my ASP.Net 2.0 Web Application. For example, UserDAL, DocumentDAL, etc... All these classes derive from BaseDAL, which stores the SqlConnection in it. The DAL classes access it through a property. The property is defined like that:
private SqlConnection connection;public SqlConnection Connection{get{ if (connection == null) connection = new SqlConnection(); if (connection.State != ConnectionState.Open) { connection.ConnectionString = ConnectionString; connection.Open(); } return connection;}}
The constructor of each DAL class is overloaded and takes a SqlConnection object. So if I need to access two DAL classes, I pass the connection of the first, to the second to prevent opening and closing the connection again and again. Here is a sample: UserDAL userDAL = new UserDAL();
userDAL.DoSomethingAndAccessConnectionProperty();
// Now userDAL.Connection is opened. Pass the connection to the constructor of DocumentDAL
DocumentDAL documentDAL = new DokumentDAL(userDAL.Connection);
documentDAL.AlsoDoSomething();
So, if I do the following:using (UserDAL userDAL = new UserDAL())
{
userDAL.DoSomethingAndAccessConnectionProperty();
DocumentDAL documentDAL = new DokumentDAL(userDAL.Connection);
documentDAL.AlsoDoSomething();
}
I assume that the connection is removed from memory, even if the DocumentDAL class has also used it. Am I right? I want to be sure that there will be no open connections.Thanks
I have a sample photo database where we have added keywords to search for photos. I wanted a way to list all of the keywords that are in the database individually. The problem is in my keyword field there are many keywords seperated by a comma.
Ex: "bull, barrel, rodeo, western, cowboy" would in the keyword field for one photo.
I wanted to select distinct all of the individual words from each keyword field in all of the records.
Can this be done? What would the query look like?
I am looking for a list like:
bull
barrel
rodeo
western
cowboy
Any suggestions?
Thanks,
Rob
If I use DISTINCT isn't there a rule where it must be the first field selected? Also, there can only be one DISTINCT field in a query, correct?
ie,
SELECT DISTINCT fieldA, fieldB
FROM tableA
but not
SELECT fieldA, DISTINCT fieldB
FROM tableA
or
SELECT DISTINCT fieldA, DISTINCT fieldB
FROM tableA
thanks again, this is a great forum

hi guys i have a query that contains several table joins
when i run the query without select distinct x,y,z,w,.. or order by docno it takes around 20 second to finish execution, when i add select distinct x,y,z,w,.. or order by docno it ruturns the same result in just 2 seconds
is adding distict keyword or order by acts as an index for the query or what ?

Hi all,
I have two datatables in my database. The first table, named Books, has two columns: BookID and Author (BookID is the primary key). The second table, named Purchases, has three columns: PurchaseID, BookID, BuyerID (Purchase ID is the primary key).
The idea here is that the Books datatable contains information regarding the book and its author while the Purchases datatable contains information on who has purchased what book.
Now, say I want to write an SQL query to extract a list of all the authors who have written a book purchased by buyer X. How would I go about doing this without having any duplicate entries? I figured that the following would work:
SELECT DISTINCT * FROM Books INNER JOIN Purchases ON Books.BookID=Purchases.BookID
But this ends up generating duplicate BookIDs if the Purchases table contains several buyers who have bought that Book. I know I could use BookID rather than * in the above query and that would work, but in reality I'm dealing with more complex tables and I would rather keep the * in there to actually get all the data out in one go.
and how do I write an if phrase?
Shimi
I heard a claim recently at a SQL Server users group meeting that theTOP keyword forces sorting on a database server. I can't find anyreason this might be true and the Books Online say nothing about it.Can someone verify this claim one way or the other?

View 3 Replies View RelatedI've been trying to figure out the usage of "Nothing" as the scope parameter, and the more I try, the more I can confused.
It says on the RDL spec:
"For expressions inside data regions:
.......
Specifying the keyword Nothing as the scope is equivalent to specifying the
outermost data region containing the report item in which the aggregate is used."
It seems that what's it saying is that if I have an expression in a table as
= last(somefield, "the name of the table")
is the same as
= last(somefield,Nothing)
But, apparently it;s not. (I tried last, first,sum, count,CountRows, min, max...........)
it doesn't matter where I put "=last(somefield,Nothing)" in the table (i tried table header,footer, detail, and table group header, footer), none of them worked.
and I tried it everywhere in matrix, in charts.
It's just not working.
It always complains about the invalid scope not being the containing data region, containing grouping or dataset name.
However, the only way I get the "Nothing" as the scope to work is in a RunningValue function, not in any other
aggregate funcitons.
Anyone help me with this, please... I need a complete definition on the usage of Nothing as scope.
Hi,
I have a table like
ProductId, Description, Description2
where Description and Description2 are text datatypes.
I'm trying to return all records where myKeyword exists as a singular word in either of these two fields.
Should I create a child table where each word in each of these fields has its own row for each product and query against that or is there an efficient way of querying this result without creating the extra child table?
Many thanks for any pointers

I'm using an application that is generating some SQL scripts for SQL Server 2005. I'm trying tweak it so that I can run it on SQL Server 2000.
The line that I'm having trouble with is:

The key word "(optional)" is causing trouble.
I understand this keyword, when used in SQL Server 2005, let's the script continue and complete when errors are detected.
What is the alternative syntax to use in SQL Server 2000?
