Multiple Join Queries?
Mar 3, 2008
I get a wo_ID and want to query company data. I have the following tables, work_orders (has wo_ID, wo_name and install_id), install_ids (has install_id, comp_id) and customers (comp_id, company_name).
The query process goes like this: I get a wo_ID and I need to find the install_id that corresponds with that wo_ID in that same work_orders table. Then take that install_id and find out the comp_id that corresponds with that install_id from the install_ids table. Finally take that customer_id and link it to comp_id in the customers table to find out company data.
I need to join it multiple times to get my final data. I have a simple one that works right now with one join and using the install_id, but I don't know how to expand it with multiple joins. Thanks.

Hello:
What is the difference between:
select * from table1, table2 where ......
And

Is there a performance difference or any other difference?

Hi,
Can you give the equivalent query for the following Oracle query :
SELECT col2, col3 FROM submission,
lkup so
WHERE so.txt (+) = TRIM(col2)
ANDso.pid (+) = 'SO'
ANDso.cde (+) = 'RW'
In the above query a constant value is used in JOIN, so I am not aware of how to use the JOIN clause for the above constant value ( 'SO' , 'RW' )
Upto my knowledge about JOIN query equivalents :
Oracle query :-
select *from test1 a, test2 b where a.sno(+) = b.col
Equivalent SQL Server query :-
select *from test1 a JOIN test2 b on a.sno = b.col
Hope the above is correct. Here my doubt is, if in the above query, b.col is replaced by a constant value say 'abcd' , then what will be the table name used in right of the JOIN clause. Or any other equivalent for this is available ?
Eg :-
Oracle query :-
select *from test1 a, test2 b where a.sno(+) = 'abcd'
Thanks,
Sam

Hi,
First, my knowledge of MDX is very limited :o
I am wondering if it is possible to return the result of 2 different queries as one. Similarly, like using UNION in SQL. I looked into the MDX UNION but it works on sets.
Basically, I have 2 queries; one with territory sales and one with region sales. I would like to return the results of all the territories followed by the sales of the region in one go.
Thanks in advance.

I am trying to do an inner join on two sub-queries, and I can't figure out what I am doing wrong here. I keep getting syntax errors:
Code:
SELECT * FROM
(SELECT SSN
FROM [1099_PER]
INNER
JOIN ( SELECT SSN, name4, count(*) from [1099_PER]
group by SSN, name4

I have a page that will require several hundred update queries to be sent to the database. How much of a performance increase will i get by joining them all into one statement and sending them as a batch instead of running them one by one?
Thanks.

I am having a problem with a query,I am not sure if i would use a join or a subquery to complete thisproblem.I have two queries, and i need to divide one by the other, but i cantseem to get anytype of join to work with them.Here is the situation.I have a projectDB table that has a list of different projects foreach employee to work on.Each project has an employee assigned to it.The start date is null until the employee starts to work on it.I want to find how many percent of all their projects that eachemployee is working on.In other words:I want to divide query A by query B to see how many percent ofprojects each employee is working on.Query A count of projects that are being worked because they have adate per employee:SELECT employee, COUNT(employee) AS cntFROM projectDBGROUP BY employee, project_start_dateHAVING (NOT (project_start_date IS NULL)) //notice the NOTQuery B: Total amount of project per employee:SELECT employee, COUNT(employee) AS cntFROM projectDBGROUP BY employee, project_start_dateAny ideas?

Hello all,
I have been using T-SQL for a while now although the majority of my work required relativley simple queries.
I just need to know is there a way to JOIN the results of several SELECT queries, maybe through the use of functions??
A reference to any online article would be most helpful.
Cheers,
Sean

I have recently started working on Sql server management studio. I have been using MS access in the past. To link results of 2 queries in MS access I would open the query wizard and it would show me the list of saved queries and then I could join them as regular tables. Im trying to look for this option in management studio. When I open query designer in management studio I am only given the option to add existing tables, how can I add existing queries?

Good morning!
Or good "whatever daytime you read this"!
SQL Server 2005 has this nice new feature Common table expression or CTE, which allows quite easy to define a "drill down" in recursive self join tables.
By recursive self join tables I mean this common example:
idPerson INT <--------|
idReportsTo INT ---------|
PersonName VARCHAR
A CTE to "go down" the tree from any entry point and find all subs to a parent entry is well documented. I managed to make myself a CTE and use it a lot!
What I find myself needing too often is:
a) Look up from a deep position and find the entry that is for example 3 steps above my reference in the branch
b) Look up from a deep position and find the one that is 2nd or 3rd level (absolute) from top of the tree in the branch
I did try quite some versions, but I cannot get it to work. Any idea how you do the "drill up" with a CTE or another SQL solution.
Of course performance is always needed, so I'd like to avoid the cursors I got it working with and use now. (It is not working good I admit...)
Cheers!

We have the follwoing environment
Sql2005 64 bit edition standard edition servers
Sql2000 Sp3 enterprise edition servers
when we try to access a table in sql2000 from sql2005 using linked server, the query also uses inner joins and max()
it gives the follwoing error
"Msg 8180, Level 16, State 1, Line 1

I have an intermittent issue where some remote PC's occasionally fail to execute select queries that have a join or return multiple result sets, however simple one table select queries continue to work okay. When it does happen the PC's needs to be rebooted to get to work again. This may only happen some PC's while others continue to work away okay.
I am using a VB6 application and ADO to connect to the database and the error message I get is a General Network Error, Server Not Found when it fails to execute the query. I have ran SQL Profiler on the server and while simple select queries continue to run away okay, a query a join does not even seem to show up in the profiler. The program has been working fine for 15 years with 1000's of users and has only now become an issue on one site for a number of users. Have tried moving the database to a different server and swapping network cards on the local PC's but can't seem to find the cause. The processor and the memory don't seem to be under load, but I am not sure if there is something else in SQL that is causing it to hang under certain conditions.
There have been network analysts experts in to run scans on the network, but I have not had the results of this back yet. Other applications do not seem to be affected so if this analysis does not show up anything.

Hello,
I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services?
Thanks

Hi
I have two queries, one which takes 1 second to execute and the other which takes less that a second to execute.
I need to join them up similar to the following but when I do it take forever for them to execute.
select *
from table
where column not in (select column from table2)
It is quite complex and I have a couple of views included in the queries but it executes quickly on my dev database and when I run it on the live one it takes forever. Granted there is alot more data on the live database but the individual queries only take a second to run.
Does anyone know why there would be such a time increase whenever I join the queries and run them on my live database?
Any help would be appreciated.
Thanks,
Frankie

I'm writing an ASP page for a project and it requires multiple queries.However, I'm trying to combine multiple SELECT statements, but can'tfigure out a way that actually works.Basically, here are the SELECT statements I want to combine:SELECT * FROM schoolrequest WHERE SLid=10SELECT SLlastName FROM academicofficeWHERE schoolrequest.SLsendToId=academicoffice.AOidSELECT SLlastName FROM academicofficeWHERE schoolrequest.SLbillToId=academicoffice.AOidSELECT SLlastName FROM academicofficeWHERE schoolrequest.SLrequestorId=academicoffice.AOidSELECT * FROM diaryentry WHERE diaryentry.DEkeyValue=10AND diaryentry.DEdeletedDate IS NULLThe academicoffice table just contains basic contact info, but needs tobe used 3 times in the query to get specific contact info for 3different contacts(SLsendToId, SLbillToId, SLrequestorId)The diaryentry table contains info entered in by students. TheDEkeyValue is actually the primary id of the schoolrequest table(SLid).Any ideas?Thanks,M

Hello everyone...
I have created a report that pulls data from 5 different tables. I have created a tableadapter for this. I have a sql stored procedure with left joins that I am trying to use but keep getting key violations and not null value violations when I try to use it. I have tried setting the NULLValue to NOT throw exception but that has not helped. I have also tried to writing a query for each table. I can add each query to my tableadapter but I can use them all at the same time for some reason. Can this be done? When I go to my report and try to add fields to it from the tableadapter, I only see the results of one query. I am only trying to SELECT. I am not doing any updates or deletes to the tables on the SQL Server.
Any advice would be greatly appreciated.

If you have a dozen or so queries related to the same thing such as an exception report do you wrangle with the query to make it a one stop shop or do you do something different? Is it possible to drop them into a SP and have them all execute at the same time?
I am running queries for against business rules and wanted to do it the right way. I don't have a solid mentor at work, two guys who are experienced and off a lot but not in the world of reports.

Hi,
I have the below query that has multiple select statements from the same query. Is it possible to run this more efficiently with a SUM/ CASE statement so that its just one SELECT ?
I just used a SUM(CASE WHEN ....... statement on another query, but I am having trouble figuring out how to integrate it on this one, and if its even possible or worth it.
Thanks very much for any help!!

I'm cleaning data which involves updating ~12 million rows with threedifferent models, progressively. First clean values using the modelwith finest granularity, then the remainder with the next model,finally what's left using the last model. The first model sets ~1/2 ofthe rows, the second ~1/4, the third ~1/5, and the remaining 5% don'tget updated.It's something like this:UPDATE t SET value=value*m.AdjustmentFactor, updateFlag='updated'FROM Table t JOIN Models m ON ....WHERE m.ModelID='first model' AND t.updateFlag IS NULLStart with 'first model' then 'second model' etc.I'm wondering what happens if I submit all three queries together, oras three separate submissions, waiting for the one before to complete.If I do them all as one group, the query planner might plan for thesecond and third updates based on the initial distribution of values.However, the first update removes half of the rows from consideration,so it seems to me a new plan should be prepared for the second query,based on the distribution at that time. If I highlight the queries inQuery Analyzer and execute, are all three plans created at thebeginning? Does putting GO between them (which I do) make anydifference?This is SQL Server 2000.Thanks,Jim

I've written a SQL script to go in and pull student grades for honor roll. The first subquery in the script eliminates any students that have any D's, and the second sub query is supposed to give me a only students that have no more than 1 C of any type as the Honor Roll criteria is that a student has to have a GPA between 3.0 and 3.49 and no more than 1 C.
If I run each individual sub query by itself they work and pull the students that they are supposed to. If I run the main query along with the first sub query to eliminate students with D's everything works. If I run the 2nd sub query by itself it will pull the students that meet the criteria. If I run the main query along with both sub queries or the main along with the 2nd sub query it doesn't work.
Here is what the query looks like that I'm trying to run.

Hi,
I have some questions about making muliple T-SQL queries againt an SQL-server. I retrieve all rows from an SQL-server table called ActivityGroup and add the result to a Radio Button List. Suppose, I also wish to add the total sum of every "ActivityGroup" value to the Radio Button List. I guess this ought to be done using a SELECT COUNT statement and then retrieved using the Executescalar method?
The question is do I need to copy the code for the SELECT ('*) statement and make the neccessary changes for the SELECT COUNT statement and Executescalar method or is there a more simple way? Is it possible to use two command statements in the same code block?
The total sum is going to be calculated using the values from both an SQL-server and an Access database. The OleDb sample below is what I refer to as a code block. I appreciate any help!
string connectionString = ConfigurationManager.ConnectionStrings["ServetteConnectionString"].ConnectionString;
string sQuery = "SELECT * FROM Aktivitetsgrupper where aktivitetsid = " + Request["AktivitetsId"];
OleDbConnection oOleDbConnection = new OleDbConnection(connectionString);
oOleDbConnection.Open();
OleDbCommand command = new OleDbCommand(sQuery, oOleDbConnection);
OleDbDataReader reader = command.ExecuteReader();
int test = 12;
while (reader.Read())
{
rblAktivitetsgrupper.Items.Add(new ListItem(String.Format("{0}, platser", reader["aktivitetsGruppNamn"]), reader["aktivitetsGruppID"].ToString()));
}

Hi,
I'm having problems manipulating the results from multiple count(*) queries.
I have a table 'RECOMMENDATIONS' holding a field called 'SCORE'. This field holds a number from 1 to 10 and has no null or zero figures.
I currently have the following three queries:
1) SELECT COUNT(*) FROM RECOMMENDATIONS WHERE SCORE IN (1,2,3,4,5,6)
2) SELECT COUNT(*) FROM RECOMMENDATIONS WHERE SCORE IN (9,10)
3) SELECT COUNT(*) FROM RECOMMENDATIONS
I now need to combine these three queries so that i can divide and multiply the resulst: (query 2/query 1)*query 3
My initial idea was:
SELECT (COUNT(*)/(SELECT COUNT(*) FROM RECOMMENDATIONS WHERE SCORE IN (1,2,3,4,5,6)))* (SELECT COUNT(*) FROM RECOMMENDATIONS) FROM RECOMMENDATIONS WHERE SCORE IN (9,10)
... but this gives a result of "0". I then stripped out the multiplication section to see if the divide was working:
SELECT COUNT(*)/(SELECT COUNT(*) FROM RECOMMENDATIONS WHERE SCORE IN (1,2,3,4,5,6)) FROM RECOMMENDATIONS WHERE SCORE IN (9,10)
... and again the result was "0"
Please could someone help me!!

I was messing around with stored procedures and I was wondering if creating a SP that populates a single table for reporting is a good idea?
I have ~10 queries that I have to currently run manually and was hoping to drop them into a physical table and then leverage that single table to pull into excel.
Some of my queries use virtual tables or CTE's, this is to get the aggregate set correctly.
Essentially I am working out of a data warehouse and would like to eventually get all my queries in one SP or something similar and then call that query for a insert.
Speaking of which could you create a SP that has several selects than with that output drops the records into a single table by using an insert into query so the data from the all the queries would line up into the right columns?

I want the data in one row with all the counts in each separate columns. Also I need to setup a flag if a client purchased and order within 30 days from their last purchase.
I am doing this select for each credit card, check and cash purchases. I do not know how to setup a flag where the client may have ordered and paid by check or cash after 30 days from a credit card purchase. Is this something that can be done?
select
clientnumber,count(distinct clientnumber) as cccnt,
0 as ckcnt, 0 as cacnt
from dbo.purchases
where orderdate >= 20120101 and orderdate <= 20121231 and
payment_type = 'CC'
group by clientnumber;
OUTPUT currently looks like this:
1234 2 0 0
1234 0 1 0
1234 0 0 4
Is it possible to result in this, along with a flag with the criteria above?:
1234 2 1 4 Y
