Hi im trying to find the difference between 2 silmilar tables in sql 2000. 1 table has 279,042 records and the other has 279,003 records, I ideally want to difference so to enable me to merge the two tables I would really appreciate any help
Hi, First post here :) Subject might not make sense, so allow me to explain. I have a table, tbl_finalized. A unique record consists of an emp_id, building, and school_year. I have another table, (call it table2) where emp_id, building, and school_year are fields as well. What I'm trying to do is... grab all the emp_id's from table 2 ( along with the school_year and building ) and then see if it exists in tbl_finalized. If it does, I don't want it. I want all the usernames in table2 that don't exist in tbl_finalized.
Here's an example: table2 contains the following record: emp_id: xxx, building: 333, school_year: 2008 emp_id: zzz, building: 333, school_year: 2008 emp_id: yyy, building: 444, school_year: 2008
tbl_finalized has the following records: emp_id: yyy, building: 333, school_year: 2008 emp_id: xxx, building: 333, school_year: 2007 emp_id: xxx, building: 333, school_year: 2008
The result I desire is: emp_id: zzz, building: 333, school_year: 2008 emp_id: yyy, building: 444, school_year: 2008
I hope this makes sense. If not, please ask and I will do my best to explain. I have light understanding of joins, but not sure how to get the difference like I desire in this case... TIA.
I have two similar tables in different database and need to make query to select only the data from the first table that is not available in the second table and there is no unique record for each record , but each row is having different records for example:
CREATE TABLE table1( [PNR] [nvarchar](10) NOT NULL, [Tkt_Number] [nvarchar](10) NOT NULL, [DepaCityName] [nvarchar](50) NULL, [ArriCityCode] [nvarchar](3) NULL,
I receive the following result set from TableA (In Time)
7/9/2013 9:27:00.000 AM 7/9/2013 10:24:00.000 AM 7/9/2013 11:25:00.000 AM 7/9/2013 1:23:00.000 PM 7/10/2013 7:27:00.000 AM
Then we receive the following result from TableB (Out Time)
7/9/2013 9:30:00.000 AM 7/9/2013 10:29:00.000 AM 7/9/2013 1:37:00.000 PM [NULL] [NULL]
We may not always get Out Times in TableB so I want to merge these into one table to have the In Time and Out Time in separate columns in that one table. In this example with the red type those should be In Time and Out Time for mapped unique identifiers from each table and yet the purple color coded example would have an In Time of 11:25 AM and the Out Time would remain as NULL.
I am using this block of code but is not working the way I want it to because the 11:25am In Time is getting mapped to the 1:37pm Out Time.
and out_time = (select min (out_time) FROM tableB WHERE tableB.record# = tableA.record# and tableB.loc_id = tableA.loc_id
GROUP BY tableB.record#, tableB.loc_id )
It seems I need to focus on the minimum datediff for each record line but can't figure that part out.
Hello Tsql experts, Can you please explain to me what the differnce is between selecting into a table and creating a new tabel and inerting in to it like so:
First way: select names into #ancestors from names
and
second way
create table #names( name varchar(10) )
insert into #names (name) values(name) select names from names
is it just personal choice or performance in one method is better than the other.Can you please explain. Thanks
Hi,I m searching for some Script / Function ... to find difference in datab/w 2 similar tables (exactly same fields structure) in sql 2000.plz update me asap !thanks in advance !

I'm new to my company, although not new to SQL 2005 and I found something interesting. I don't have an ERD yet, and so I was asking a co-worker what table some data was in, they told me a table that is NOT in SQL Server 2005's list of tables, views or synonyms.
I thought that was strange, and so I searched over and over again and still I couldn't find it. Then I did a select statement the table that Access thinks exists and SQL Server does not show and to my shock, the select statement pulled in data!
So how did this happen? How can I find the object in SSMS folder listing of tables/views or whatever and what am I overlooking?
What is the difference between below? And how can I make GETDATE() the same as System.DateTime.Today.ToShortDateString()? System.DateTime.Today.ToShortDateString() and GETDATE()

Are SQL Server Express & SQL Server 2005 one & the same thing? Or is the former a part of the latter? Actually when I was downloading Visual Web Developer 2005 Express, I was given the option to download Microsoft SQL Server 2005 Express Edition as well; so I am getting confused between SQL Server Express & SQL Server 2005.
I installed SQL Server 2005 in my WinXP Pro m/c. from the Microsoft website (after re-installing WinXP Pro since XP became corrupt). Earlier I used to login to Management Studio Express using my m/c. name followed by a followed by SQLEXPRESS as the server name. So if my m/c. name is MyPC, then I used to login to Management Studio Express using MyPCSQLEXPRESS as the server name but now when I try to login to Management Studio Express using the above server name i.e. MyPCSQLEXPRESS, then an error gets thrown saying
Cannot connect to MyPCSQLEXPRESS.
Now how do I find out what's the server name so that I can login to create & manage databases in Management Studio Express?
Please note that after re-installing WinXP Pro, my m/c. name has remained the same; I didn't change it.

I have dateadd, datediff, but I am unable to figure out the 2 problems above.thank you,
In my table i have two cols and datatype datetime, for example they has the values,--------StartDate --------------------------------------- StopDate ------______________________________________________01/05/2005 7:30 AM ------------------------ 03/05/2005 10:00 AM13/05/2005 2:30 PM ------------------------- 01/08/2005 8:00 PM_____________________________________________How do I find out the avg time difference between StopDate and StartDate? I tried AVG(StopDate - StartDate ), but it's giving me the following error message. "The average aggregate operation cannot take a smalldatetime data type as an argument."Thanks for any reply.
