How do we do this in SS2k5?
in
EXEC(sqlstring)
sqlstring wants to pass back a resultset to the caller.
- Local temp tables are out of scope.
- Global temp table works but is a bad idea.
- Table variables not supported as OUTPUT parameters for EXEC.

I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables.
* Get last 3 months data from source table.
* Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.

Let say I have 6 tables. I want to autogenerate the PK for each table and that is unique for each table and cant be duplicated on other tables. Let say I have table with PK of 1, so table2 to table6 wouldnt have a PK of 1. If table2 have a PK of 2, table1, table3 to table6 wouldnt have a PK of 2. Same for others. Identity will not be appropriate. Will 'uniqueidentifier' data type suffice? How bout guid? Or what must be my datatype? Or what will I do to implement this? Any links? Thanks

Everytime I insert a record , that field will increase 1 (type bigint , start from 1).

Hi, I have following table
BetId GameId
==== ======
500 108
500 109
501 108
501 109
501 110
502 108
502 109
My query would have the form: select BetId where GameId in(108,109)
from Bets then it has to get me BetId : 500 and 502.
Not 501,since this is different combination(108,109,110) ;)

Hello,
I would like to store some frequently asked questions in a database.
As those questions/answers could be translated in several languages, I was thinking of using two tables :
The first table would contain a unique field : the key wich is an id for each faq.
The second table would contain those fields :
FAQ_ID : foreign key
LANG : language
QUESTION : the question translated in the good language.
ANSWER : the answer translated in the good language.
What I find embarrassing, is that first table just contains a unique field : the id. But it allows :
- to have a table in which a line correspond to an object. It is convenient for object relational mapping.
- it is more evolutionary. If, in the future, I have to add some statistics that concerns a faq, I will have the possibility to store them in the first table, avoiding in this way to duplicate data.
But, one more time, I find a bit embarrassing having a table with a unique field...
What is your opinion about that ?
Thank you in advance for any suggestion.

I have a stored procedure that appends data from a temp table to a destination table. The procedure is called from an aspx web page. The destination table has an index on certain fields so as to not allow duplicates.
The issue I'm having is if the imported data contains some records that are unique and some that would be duplicate, the procedure stops and no records are appended. How can I have this procedure complete it's run, passing over the duplicates and appending the unique records? Since the data is in a temp table (which gets deleted after each append) should I run some sort of 'find duplicates' query, and delete the duplicates from the temp table first, then append to the destination table?
Thanks in advance.SMc

I need to to have a table that has a counter field (used to generate an id code for a record). This is not the primary id for the field but just a counter to label a record in another table, similar to a registration code for an event. This is a sequential counter that will start 1 and go up on each new record inserted into other tables. What I want to do is be able to query this counter table to get the next valid number and increment the count for the next time. This is a multi user web app so needs to prevent duplicate use of same number.How best should this be handled? A transaction to query and update the field?

Hello,
I am using SQL Server 2005 and am having trouble with making a history table like mentioned in my earlier thread:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=102811
This is the table "People" I have created:
|PersonId (PK)|DateFrom (PK)|DateTo|PersonName|Other Attributes....
Each change to a person's attributes results in a new row formed with the same PersonId as in the row with old attributes and the Date these new attributes are valid (DateFrom). So as shown above the Primary Key is a combination of the PersonId and DateFrom as a change to a person's attributes should never happen at the same time twice.
My problem is when I want to create a new person, how do I get a new unique id? Ideally I want the a new incremented id, so that all peoples' ids are in a sequential order.
As always, thanks for the help!

Is it possible to create a unique constraint to a column from anothertable? For example:tb_current:current_names--------------aaabbbtb_new:new_name--------cccNow I want to create a constraint on tb_new.new_name to be unique withrespect to tb_current.current_names. However, tb_new.new_name shouldnot be unique to itself. So I should not be able to insert 'aaa' totb_new.new_name. But I should be able to insert 'ccc' totb_new.new_name.Here's the script to reproduce this example:create table tb_current(current_names varchar(10))create table tb_new(new_name varchar(10))insert tb_current values ('aaa')insert tb_current values ('bbb')insert tb_new values ('ccc')select * from tb_currentselect * from tb_newinsert tb_new values ('aaa') -- this should NOT be allowedinsert tb_new values ('ccc') -- this should be allowed

I need to develop a strong licensing solution based on the database accessed...
Currently our solution is easily hackable because the the license information is kept in the database of your choice and is not dependant on some static information, the current encryption key is static and kept in the software so it can be hacked easily. What i want to do to change this is simple in nature but i don't know how to get that one particular info i need.
I want to get some kind of unique identifier for a database (catalog) that sql server could generate. This info must be static and must not be movable. If for example, someone would backup and restore, this information would not be transfered with the backup. Thus, a user that backups his database and restores it on another database server or another database catalog even on the same server would corrupt his license since the Unique ID returned by the SQL Server would be different; the hashing code would change and thus the decryption would fail.
Is there any such info i can query using SQL that will not require admin rights?

hello,
i have two datasets. i want to insert all data from one dataset to other.
i am using this:DataSet old = new DataSet();
download dd = new download();old = dd.contactlist("select", "admin", "001");
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Project1ConnectionString"].ToString());
try
{string cmd = "select * from contact";
SqlDataAdapter danew = new SqlDataAdapter(cmd, conn);DataSet dsOld = new DataSet();DataSet dsNew = new DataSet();
dsOld = old.Copy();
danew.Fill(dsNew);
DataTable dtOld = dsOld.Tables[0];DataTable dtNew = dsNew.Tables[0];
//int i;foreach (DataRow objRow in dtOld.Rows)
//for(int i=0; i<dtOld.Rows.Count; i++)
{DataRow row;
row = dtNew.NewRow();
row["company"] = objRow["company"];
row["cust_no"] = objRow["cust-no"];row["sman"] = objRow["sman"];
row["first_name"] = objRow["first-name"];row["contact_title"] = objRow["contact-title"];
row["type"] = objRow["type"];row["contact_loc"] = objRow["contact-loc"];
row["cust_name"] = objRow["cust-name"];row["addr1"] = objRow["addr1"];
row["addr2"] = objRow["addr2"];row["city"] = objRow["city"];
row["state"] = objRow["state"];row["zip"] = objRow["zip"];
row["territory"] = objRow["territory"];row["phone"] = objRow["phone"];
row["fax"] = objRow["fax"];row["extension"] = objRow["extension"];
row["email"] = objRow["email"];row["rec_key"] = objRow["rec_key"];
dtNew.Rows.Add(row);
}DataSet nds = dsNew.GetChanges();SqlCommandBuilder bld = new SqlCommandBuilder(danew);
danew.Update(nds);
}
here rec_key is the primary key.
this code works fine but it will insert all data from one dataset to other each time i click a button but i wanted that if data with a rec_key already exists will not insert. only unique values of rec_key will be inserted.
i am using this code for this:foreach(DataRow rr in dtNew.Rows)
{
if (rr["rec_key"] == objRow["rec_key"])
{
Response.Write("same");
}
else
{
dtNew.Rows.Add(row);
}
}
but this doesn't work.
please guide me how can i do this.
thanks

tbl_LEM ON tbl_employee.employee_ID = tbl_LEM.employee_IDREF
The results somehow need to be distinct by tbl_lems.lem_ID

I'm currently using Oracle sequence and doingsomething like:select seq.nextval from dual;Then I do my insert into 3 different table all using the same uniqueID.I can't use the @@identity function because my application uses aconnection pool and it's not garanteed that a connection won't be usedby another request so under a lot of load there could be major problemsand this doens't work:insert into <table>;select @@identity;This doesn't work because the select @@identity might give me the valueof an insert from someone else's request.Thanks,Brent

I have a table 'Group2Operation' that stores many to many relationsbetween the 'Group' table and the 'Operation' table (each group is haspermission to perform one or more of the available operations)PROBLEM=======I need to prevent duplicate entries being created. e.g. lets say thatin the 'Group2Operation' table a record links the 'editor' group tothe 'publish' operation. Should I prevent an administrator creating aduplicate of that record? (Otherwise deleting that permission willhave to be done twice or more for it to be effective)SOLUTION?=========So far I've done this with a trigger:CREATE TRIGGER Group2OperationDuplicates ON dbo.Group2OperationFOR INSERT, UPDATEAS UPDATE Group2OperationSET NoDuplicate = CONVERT(nvarchar(10),GroupID) + OperationTagThe 'NoDuplicate' unique index column in the Group2Operation tablestores a concatenation of the unique group and operation identifiers.So when an attempt is made to create a record, the trigger is fired.If there is a duplicate, this will mean a duplicate entry in the'NoDuplicate' column. As a result, the INSERT or UPDATE will fail andthe duplication will be prevented.WHAT DO YOU THINK?==================What do you think? Am I going about this in the right way? Is atrigger a good way to do this or should I rely on application logic toprevent duplicates?Any help appreciated by this db novice.John Grist
