Grabbing The Difference Between Two Tables...
Jun 17, 2008
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.

Hi,
I am passing a parameter and executing two tables and grabbing it's data.. In the future I will put the code into a store-procedure.
--Exec Table 1
declare @id varchar(20), @MEMBER_ID varchar(20)
set @id=null
set @MEMBER_ID ='55555' --ie. 55555
Select id from emp Where MEMBER_ID = @MEMBER_ID
--Okay, Next I need to execute another table and pass in the id
--that was selected from the emp table.
SELECT EMAIL FROM moreInfo WHERE id = @id
Currently, the emp table displays ie. 100 records that matches the member id 55555.. But the second select is empty.. And I need to display email data for the 100 records that were selected from the emp table..
I hope is it not confusing what I am trying to do..
Please tell me how to do it..
Thank you...

Ok I think I will need to use a temp table for this and there is no code to share as of yet. Here is the intent.
I need to insert data into two tables (a header and detail table) the Header Table will give me lets say an order number and this order number needs to be placed on the corresponding detail lines in the detail table.
Now if I were inserting a single invoice with one or more detail lines EASY, just set @@Identity to a variable and do a second insert statement.
What is happening is I will be importing a ton of Invoice headers and inserting those into the header table. The details are already in the database across various tables and and I will do that insert based on a select with some joins. As stated I need to get the invoice number from IDENTITY of the header table for each DETAIL insert.
I am assuming the only way to do this is with a loop... Insert one header, get identity; Insert the detail table and include the IDENTITY variable, and repeat.

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,
[Code] ....
Output should be like this
PNR | TKT_NUMBER | DEPACITYNAME | ARRCITYCODE | NAME

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

I have a pretty big SQL query with a one to many sort of relationship...
There are client accounts that we're reporting on. Each account has four different historical categories attached. Each historical category can have maybe fifty entries in each, sorted by date.
I need to figure out how to grab the unique accounts and show only the three most recent results per each historical subcategory with the account... the three most current results from each of the four subcategories, displayed by the parent client account number.
I've created four views to isolate the subcategories as a start, thinking I could bring them into a parent query ...
but my question would be... how do I generate JUST the top three historical transactions by account number? If I select TOP 3, I get only the 3 newest in the MASTER LIST, not per client account, which is what I need to do.
Does this make sense? I could really use a good SQL helping hand with this one.
Thank you!

I have a table:
Code:
serverid | value
12 | languages
12 | php
12 | coldfusion
12 | mysql
12 | mssql
12 | asp
14 | languages
14 | php
14 | asp
16 | languages
16 | php
16 | coldfusion
16 | mysql
16 | mssql
15 | languages
15 | coldfusion
15 | mssql
i need to get all serverid of those that have entries for "languages", but dont have rows for php, asp, and coldfusion.
so in the above example, i would get 15 and 16.
i dont think i can do in one statement?
sql Code:
Original
- sql Code
SELECT t.serverid FROM table t WHERE t.value = 'languages' AND (t.value != 'php' AND t.value != 'asp' AND t.value !='coldfusion')
SELECT t.serverid FROM TABLE t WHERE t.value = 'languages' AND (t.value != 'php' AND t.value != 'asp' AND t.value !='coldfusion')
i think that above statement is completely wrong already ( I think it would need to do a select statement inside the WHERE clause)
i think i would need to maybe create a temp table and use a cursor?
any ideas or help ?

Hi folks,
I'm a little new to SQL programming but I'm learning. :)
I need to do a join on a table where I exclude records that have more than one urn (unique record number).
In the example table below I want to exclude both entries in the cr_urn column of 49074 & 49075.
cr_urn proc_urn crs_seq crp_seq crp_site
49073233311NULL
49074205111NULL
49074261512NULL
49075128011NULL
490752185121945
49076233311NULL
49077233311NULL
490781145121875
To get to this ->
cr_urn proc_urn crs_seq crp_seq crp_site
49073233311NULL
49076233311NULL
49077233311NULL
490781145121875

Howdy,
Am trying to find a way to insert/update/delete data in a SQL mobile database on a Windows CE 5.0 device FROM a desktop PC.
This situation is completely stand alone, no network (apart form device/desktop), no GPRS etc etc etc.
I've looked at RDA but i dont believe it fits my app. (pulling data from a 2005 server that doesnt exist doesnt really help me much, push can't be used without a pull which kills the idea.)
The goal is a UI on the desktop that can manipulate data in the SQL mobile Database.
I've tried all i can find/think off in relation to this but to no avail.
My latest attempt has been using the simplest method possible (using a VS wizard datasource to the devices DB and tryign to whack that on a form) but this just creates a "Path not found. Check the directory for the database [Path = Mobile Device/ce_swipe/TestDB.sdf".

I tried checking to see if the point at which the reader was, that if it was the record I am looking for to go ahead and add the table data to a label. But for some reason it's only taking the first record in the database and not the one I thought I was at.[CODE] public void UpdateMaleHistLbl() { SqlConnection conn = new SqlConnection("Server=localhost\SqlExpress;Database=MyFamTree;" + "Integrated Security=True"); SqlCommand comm = new SqlCommand("SELECT * FROM FatherHistTable, MotherHistTable, UsersTable WHERE UsersTable.UserName = @usrnmeLbl ", conn); comm.Parameters.AddWithValue("@usrnmeLbl", usrnmeLbl.Text); conn.Open(); SqlDataReader reader = comm.ExecuteReader(); while (reader.Read()) { string usr = reader["username"].ToString(); usr = usr.TrimEnd(); string pss = reader["password"].ToString(); pss = pss.TrimEnd(); if (usrnmeLbl.Text == usr) { if (hiddenpassLbl.Text == pss) { maleHistLbl.Text = reader["GG_Grandfather"] + " > "; maleHistLbl.Text += reader["G_Grandfather"] + " > "; maleHistLbl.Text += reader["Grandfather"] + " > "; maleHistLbl.Text += reader["Father"] + " > "; maleHistLbl.Text += reader["Son"] + " > "; maleHistLbl.Text += reader["Grandson"] + " > "; maleHistLbl.Text += reader["G_Grandson"] + " > "; maleHistLbl.Text += reader["GG_Grandson"] + "<br /><br />"; } } break; //exit out of the loop since user found } reader.Close(); conn.Close(); }}[/CODE]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?
Thanks,
Keith

Is there really a difference of approach?
I have several things to consider in an estimating database. Production, Shipping, Field Work, Field Hardware, etc...
All of the above have account numbers. Now I was wondering, would there be any benifit to having one table or several tables?
One Table Example
Account (PK) | Category | Description
or
Multiple tables
tbProduction
Account (PK) | Description
tbShipping
Account (PK) | Description
tbProducts
Account (PK) | Description
etc.....
I like having the tables split up and/or all in one.
Any thoughts, pros / cons?
