SQL Ver: 2008 (not r2)
Problem: The following code returns correct results when moving variable declarations and update statement outside a stored procedure, but fails to return a value other than zero for the "COMPANY TOTAL" records. The "DEPT TOTAL" result works fine both in and outside the sp.This may have to do with handling NULL values since I was getting warning message earlier involving a value being eliminated by an aggregate function involving a NULL. I only got this message when running inside the sp, not when running standalone. I wrapped the values inside the SUM functions with an ISNULL, and now return a zero rather than NULL for the "COMPANY TOTAL" records when running inside SP.All variable values are correct when running.

Hello, I have these variables on my page:
userid = "10101"
RequestHost = "example.com"
What would be the best way performace wise to first check if the userid 10101 exists in my sql server db. If it does exist I would then need to check if "example.com" exists for the userid in the userdomains table. If these both exist I would then like to query some additional data. I was hoping its possible to combine this into one query somehow. I dont think this is the best solution:
sqlcommand.CommandText = "SELECT UserId From Users Where UserID = '10101'"
Conn.Open()
dr = sqlcommand.ExecuteReader
if dr.hasrows then
sqlcommand2.CommandText = "SELECT UserDomain From UserDomains Where UserID = 'example.com'"
dr2 = sqlcommand2.ExecuteReader
if dr2.hasrows then
sqlcommand3.CommandText = 'Select Additional Data
dr3 = sqlcommand3.ExecuteReader
'read values
conn.close
else
conn.close
'do something
end if
else
conn.close
'do something
end if Thanks Very Much!

Hi,
I wonder if anyone can help. All I am trying to do is combine three SQL SELECT queries into one. They are:
SELECT COUNT(ISNULL(Result, 0)) AS Win FROM Games WHERE (CurrentSeason = 'True') AND Result = 'Win'AND ([MatchType] = @MatchType)
SELECT COUNT(ISNULL(Result, 0)) AS Lose FROM Games WHERE (CurrentSeason = 'True') AND Result = 'Lose'AND ([MatchType] = @MatchType)
SELECT COUNT(ISNULL(Result, 0)) AS Draw FROM Games WHERE (CurrentSeason = 'True') AND Result = 'Draw'AND ([MatchType] = @MatchType)
As you can see they are all doing pretty much the same thing. I have experimented by using GROUP and HAVING but end up with no results. Sorry if this is obvious but I am new to SQL!
Many Thanks
I have a table that has two dates in it, a date opened and a dateclosed. I would like to create one query to give me the number ofrecords that have been opened each month plus, and this is the hardpart the number of those records that have been closed each month. Ican get the result with two seperate queries but have been unable toget it combined into one query with three values for each month, i.e.,the month, the number opened and the number of those that were openedin the month that have been subsequently closed.Here's my two queries.

I know there has to be someway to combine these into 1. The issue I have is they are in different databases.
ANY HELP would be appreciated.
I'm trying to create a list of orders in my db that has been created correctly (some orders are not dealt with correctly...) An order should go from "open -> assigned" to "assigned -> responded" status.
I got the following query:
select org.name, count(order) AS correct, NULL AS Total
from order
left join orderstatus o1 on order.id = o1.order_id
left join orderstatus o2 on order.id = o2.order_id
left join org on order.orgid on user.id
where
o1.status = 'Open -> Assigned'
and o2.status = 'Assigned -> Responded'
and o1.time_stamp < o2.time_stamp
This gives me a list of all organisations with the correct number of orders in the system...
But now I need to add the total number of tickets they got in the system. So I was thinking about a union with a query without the were constraints
UNION 'with the above query
select org.name, NULL AS correct, count(order) AS Total
from order
left join orderstatus o1 on order.id = o1.order_id
left join orderstatus o2 on order.id = o2.order_id
left join org on order.orgid on user.id
..but that gives me a list like this:
name correct total
org1 324 NULL
org1 NULL 423
How can I combine them, or maybe doing it a better way?

I have two SQL queries that I would like to combine. Each query is dependent on the same table, and the same rows, but they each have their own WHERE statements. I've thought about using some JOIN statements (left outer join in particular) but then I run into the problem of not having two separate tables, and don't see where I can put in two separate WHERE statements into the final query. I've read into aliasing tables, but I'm not quite sure how that works (how to put it into code or a JOIN statement) , or if it would solve my question. Do you have any ideas or examples of how to solve this scenario?

I have two queries that I'm trying to combine, but can't figure out how to combine them ... successfully!?! The first query is pretty simple in that I'm looking at several fields from two different tables, no big deal.
The second query calculates the years, months, days between two dates that are used in the first query. I'm stumped on how to combine the queries so that they place nice with each other and return results.
Here's the first query ...

vpi.PositionReason, vpi.PositionCode, vpc.PositionCodeDescription
from vhrl_positioninfo vpi
inner join position_codes vpc on vpi.PositionCode = vpc.PositionCode
Here's the second query ...
select

convert(varchar, [Months]) + ' Months ' +
convert(varchar, [Days]) + ' Days', *

I would like to pull all the columns from a table where the date column is within 6 months from the max date (i.e. Jul, Aug, Sep, Oct, Nov, & Dec). In addition to that, I would like to pull another column -the summary column - from the same table where the date = max(date) (Dec only).
I have written 2 queries and they produce the correct data. However, I don't know how to combine them into one resultant table. I tried to do a left join and had difficulties dealing with the different where statements from the 2 queries..
Here is query #1:
select investor, full_date, month_end_summary, category, loan_count
from cust_table
where datediff(month,full_date,(select max(full_date) from cust_table)) < 6
group by investor, full_date, month_end_summary, category, loan_count
order by investor, full_date
Here is query #2:
select investor, full_date, month_end_summary
from cust_table
where datediff(month,full_date,(select max(full_date) from cust_table)) =0
order by investor, full_date
Can they be combined into one query to produce one result table??
I have a database with 2 log files VE_log and VE_log2 (the split is left from legacy system with limited disk space). I want to eliminate the 2nd log.
I've tried SHRINKFILE (EMPTYFILE), which of course reduces the file to the default minimum pages, SHRINKFILE (TRUNCATEONLY), SHRINKDATABASE (VE), and in every case the ALTER DATABASE REMOVE FILE command fails cause the log isn't empty.
Ideas???

Looking at perfmon, I can see that SQL Server 2005 is running the CPU near 100% -- but I don't know what it's doing. How can I see a list of the queries that are currently executing?
Better yet, is there a more general "what is the database busy with right now" diagnostic tool somewhere? (I know I can capture a trace, but that won't show me what's already running, AFAIK.)
Thanks for any help...
HelloWhen I use a PreparedStatement (in jdbc) with the following query:SELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = ?ORDER BY group_nameIt takes a significantly longer time to run (the time it takes forexecuteQuery() to return ) than if I useSELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = 'M'ORDER BY group_nameAfter tracing the problem down, it appears that this is not preciselya java issue, but rather has to do with the underlying cost of runningparameterized queries.When I open up MS Enterprise Manager and type the same query in - italso takes far longer for the parameterized query to run when I usethe version of the query with bind (?) parameters.This only happens when the table in question is large - I am seeingthis behaviour for a table with > 1,000,000 records. It doesn't makesense to me why a parameterized query would run SLOWER than acompletely ad-hoc query when it is supposed to be more efficient.Furthermore, if one were to say that the reason for this behaviour isthat the query is first getting compliled and then the parameters aregetting sent over - thus resulting in a longer percieved executiontime - I would respond that if this were the case then A) it shouldn'tbe any different if it were run against a large or small table B) thisperformance hit should only be experienced the first time that thequery is run C) the performance hit should only be 2x the time for thenon-parameterized query takes to run - the difference in response timeis more like 4-10 times the time it takes for the non parameterizedversion to run!!!Is this a sql-server specific problem or something that would pertainto other databases as well? I there something about the coorect use ofbind parameters that I overall don't understand?If I can provide some hints in Java then this would be great..otherwise, do I need to turn/off certain settings on the databaseitself?If nothing else works, I will have to either find or write a wrapperaround the Statement object that acts like a prepared statement but inreality sends regular Statement objects to the JDBC driver. I wouldthen put some inteligence in the database layer for deciding whetherto use this special -hack- object or a regular prepared statementdepending on the expected overhead. (Obviously this logic would onlybe written in once place.. etc.. IoC.. ) HOWEVER, I would desperatelywant to avoid doing this.Please help :)
View 1 Replies View RelatedI'm creating a search function right now and I'm running into a problem where my search function doesn't know what fields the user will search for, and therefore doesn't know whether or not to put quote marks around specific values or not.
For example, somebody might search for somebody else with year of birth in which case I might have a query:
SELECT userid FROM users WHERE yob = 1970
but somebody else might search for a name, in which case I need
SELECT userid FROM users WHERE first_name = 'Andrew'
or somebody else might search for both and need
SELECT userid FROM users WHERE yob = 1970 AND first_name = 'Andrew'
I'm accomplishing this by having the function (this is in PHP) take an array as an argument, where the key is the MySQL column and the value is the required value for that column. So in the 3rd example, it would be a 2-item array:
yob => 1970

And then cycling through that and dynamically creating a MySQL query based on the received array.
So... my problem is finding a way to specify when quote marks are required and when they're not. Is there any way to just have MySQL default to the format of the column? Also, if anybody thinks this isn't the right way to create a search function, let me know because I'm new at this .
Thanks!
PS: Right now what I'm doing is I'm creating arrays that include names of columns that do and don't need quote marks. Then in construcing the MySQL statement I'm checking to see which array a column is in, and making the quote decision based on that.
1. could any one tell me in a simple way how to troubleshoot long running queries.
2.what is the default recovery model
Hello,

Can any one help me?
Thanks

I have a large number of relatively simple sql queries that each perform tests on different tables returning different columns and rows for each test.
I would like to be able to run all of these at once and get the output in a usable format.
Would it be possible to run a single query or store procedure which could perform each test then output the results from each test to a new sheet in excel?
Could it output the results of each test to individual csvs?
I have written quite a complex query in Query Analyser, now need toknow how to automate the running of the query to dump the results intoa flat file at scheduled times. Am an experienced Unix user, where itwould be quite simple but new to sql server, is there a relativelysimple way to do this?

Hello
Could you please help me solving this problem?
I have a stored procedure called subscribe for inserting a new row to subscriptions table. Then I added a new query (nonquery) to my dataset called 'Subscribequery' for handling the stored procedure.
now, I want to run the query lke this:
DataSet1TableAdapters.SubscribeQuery C = new DataSet1TableAdapters.SubscribeQuery();
C.Subscribe(Profile.UserName, Convert.ToInt32(Subscriptions.Rows[1].Cells[1].Text));
but nothing is added to table. what can I do?
Should I be looking for something like Update(dataset) method for my query?
many thanks in advance

Hello All
I have queries which take over 30 secs to run, which I wish to monitor.
Currently, I am monitoring using sql profiler.
Is there any way of setting up mail to e-mail me when such a query happens.
Could I set up an Alert, or is there some other method.
I want to be able to react to these events faster before the users complain.
I am using sql server 7 enterprise and I have exchange set up.
Any help would be great

When I execute this stored proc it runs for more than 5 minutes. Is there anything i can do to speed it up? Maybe there is a faster way of writing these queries?

Is there any way to measure the progress of a long running query,
for instance, to find where in a query plan a query is in SQL 7.0?
I have a query I am running that is currently 2 1/2 hours into the
query. Since it's joining three large tables, one with 42 million rows
and two with 7 million rows, I'm expecting the query to take a
while. However, I have no way of estimating exactly how long
it will take. Before I ran it, I optimized it the best I could in
Query Analyzer using an estimated query plan, making sure I had
all the right indexes, etc. I've been trying to use the estimated cost
to project query time, but that hasn't been working since queries
with similar costs can take radically different amounts of time to
execute.
Now I'm sitting here waiting, wondering if the query is just taking
too long, and I should stop it and work on optimizing it some more
(since I will have to run a couple more queries like it), or let it
finish. But I have no clue how close it is to finishing. I've tried looking
at the Physical I/O given by sp_who2 and then trying to calculate the
number of pages it would have to read if it had to read everything
from disk, then estimating it's progress by that, but this seems dubious
at best, since I don't know a whole slew of factors (ie: how many
pages are being read from the cache, is my page calculation correct,
etc).
So, does anyone know of any way to figure out how soon a long
running query will finish in SQL 7.0?
Thanks.

Permission problem w/ users running some queries
I have a SQL-authenticated user that I want to be able to run a pass-thru query. The user was created solely for this particular job. I've given it appriopriate permissions on all the tables, views, and stored procedures directly involved in the task. BUT, the task fails.
If I have the query perform a simple task, like SELECT * FROM TABLE, it works,
but, not on this:
CREATE PROCEDURE sp_gtn_RunFromAccess AS
EXEC msdb..sp_start_job @job_name='CA_GTN Download From Mainframe'
GO
If I give the user the DB_OWNER role, it fails; however, if I make it a sys admin, it suceeds. That is obviously no good. It also suceeds it I put sa and a password in the ODBC string, but that is unacceptable, as well.
What kinds of permission am I overlooking?
Any thoughts on this?
Thanks,

An general question.
A database table contains a textfield with queries. Is it possible to run them with another query.
Code:
----ID----|-------------SQL------------------
0 |"Select * from table0
1 |"Select * from table2 where x = 3
or so?
Does any one know? It would be nice if possible very dynamic but perhaps not so safe?
