Let's say I have a table of users.
Let's imagine there's two fields:
username (PK),
password
Now I need to authenticate a user against this table. What is the recommended approach? Is it better / faster to
(1) SELECT * FROM [User]
WHERE username = 'whatever' AND password='whatever'
or
(2) SELECT * FROM [User]
WHERE username = 'whatever'
and then in my code check that the record returned matched the password?
It seems when I run the query with the set staticts IO on then statistic reports back with the 'work table', and the query takes 30+ sec. if the worktable is ommited(whatever the reason?) the query take less 1 sec.
Here is my take, I believe work table is created in tempdb...and if not then whole query is using the cached page, am I right?
if I am right then the theory is, if I increase the (via sp_configure) server min memory setting and min query memory, the query ought use the cached page and return in less 1 sec. (specially there is absolutely no one but me on the server), so far I can't make it go faster...what setting am I missing to make it run faster?
Another question is if the query can not avoid but use the tempdb, is it going to always be 30 sec+ time? why is tempdb involvement make it go so much slower?
Thanks in for you help in advance
I have two tables - products and productpropertyvalue
I need to select multiple fields from the productpropertyvalue as it corresponds to the product id. The script I am using is
select a.id, a.productname, a.siteprice,
b.propertyvalue
from product a, productpropertyvalue b
where a.id = b.productid and propertyid=590
This allows me to extract only 1 propertyid. I need to make it add 3 other columns for propertyid=589, 617, 615
Any help solving this problem would be appreciated - thanx!

I remember seeing a fancy query that checked for multiple fields in a table (I think using a select statement in the where clause but not sure), but can't remember how to do it... here is what I want to do (and maybe there is a much easier way). Thanks!
Table1
id item color
1 shoe red
2 shoe blue
3 coat green
4 coat black
Table2
item color
shoe red
coat green
I want everything in Table1 where item and color are not a match.
So my results should be:
2 shoe blue
4 coat black
I'm sorry if this is a dumb question... it's been that kind of a day!
Thanks!
An ADODB error spawn everytime I query more than 15 fields in a specific SQL Table. My sql statement is something like this:
set rs=server.createobject("ADODB.Recordset")
rs.open "select * from mytbl",application("mycon"),1,3
And the error is something like this:
"you can't query more than the maximum field "

I have the following insert query which works great. The purpose of this query was to flatten out the Diagnosis codes (ex: SecDx1, SecDx2, etc.) [DX_Code field] in a table.

INSERT INTO reports.Cardiology_Age55_Gender_ACUTEMI_ICD9

SecDX8 = [8],
SecDX9 = [9],
SecDX10 = [10],

SecDX15 = [15]

[7], [8], [9], [10], [11], [12], [13], [14], [15] )) pvt
ORDER BY Episode_Key
The query below also works fine by itself. You may notice that the Episode_Key field appears in both the query above and below therefore providing a primary key / foreign key relationship. The srm.cdmab_dx_other table also appears in both queries. I would like to add the fields in the select statement below to the select statement above. Using the relationships in my FROM statements, can anyone help me figure this one out?

I am using MS SQL 2012. I have a table that contains all the data that I need, but I need to summarize the data and also add up decimal fields while at it. Then I need a total of those added decimal fields. My data is like this:
I have Providers, a unique ID that Providers will have multiples of, and then decimal fields. Here are my fields:
ID, provider_name, uniq_id, total_spent, total_earned
Here is sample data:
1, Harbor, A07B8, 500.00, 1200.00
2, Harbor, A07B8, 400.00, 800.00
3, Harbor, B01C8, 600.00, 700.00

6, LifeLine, L01D8, 200.00, 800.00
I need the results to be just 3 lines:
Harbor, A07B8, 900.00, 2000.00
Harbor, B01C8, 900.00, 1800.00
LifeLine, L01D8, 900.00, 2100.00
But then I would need the totals for the Provider, so:
Harbor, 1800.00, 3800.00
Hello,
Lets say I have a SP that return 1000 records,
do I get any better speed if doing it on a SP instead of just SELECT without an SP ?
if I have many users on a web-site that will execute this SP - will they get any better
speed because it is a SP ? - can SP cache itself - if so - for how long ?
(Why should I use SP if not passing any parameters ?)

I'm talking about three times slower using the Select MyField sintax.
Any ideas???

Hi y'all,
I've recently run a profiler on my code and following query took 7 seconds:
SELECT TOP 10 UI, COUNT(UI) AS Expr1 FROM table WHERE (UI <> 'custom_welcome') GROUP BY UI ORDER BY COUNT(UI) DESC
Is it possible to rewrite this so my code gets faster? It's also possible that it's due to the size of the table?
Thanks in advance! I'll let you know how long your query takes :)
Hi!
I M basically an application developer & use simple sql queries in my programmings. I do not have much idea abt tuning/auditing part & thatswhy i m unable to answer them properly in my interviews. Can anybody give me some tips?????
Question 1:
In a stored procedure, One SELECT stmt is there & depending upon the @rowcount, it updates around 14000 records which is also written inside this stored procedure. Instead of writing this way, there is some other way which is faster than this. Can anybody tell me the correct way???
Question 2:Can anybody give me few examples like this?????? I need them desparetly.
Thanx. Bye.
I have rewritten a stored procedure that consists of a single select that selects from a view. Essentially I combined the select in the view and the select in the sp into one select. I am now trying to determine if the new version is faster.
The estimated execution plan gives a ratio of 96% : 4% in favour of the new version when I run them together from a query window but when I try to time them I can't get a satisfactory result.
If I run each query once and display the difference between start and end time, they display 0. If I run each one 100, 200, etc times I get different results each time.
Is there anything I can do?

Hey guys, I have a brain buster for you today:
I have a query where I need to select a bunch of rows from one table, hypothetically we'll call them ssn, first name, last name, and I need to select a subquery which coalesces a bunch of rows together (in no case will there be only one row returned from that subquery).
Anyone know how I could go about this? I'll give you an example of what I've tried, but it does not work currently.
delcare @path varchar(255)
select e.ssn,
e.firstname,
e.lastname,
( @path = select coalesce(@path + ', ', '')
from space s1 inner join space s2
on s1.lft BETWEEN s2.lft AND s2.rgt and s1.rgt BETWEEN s2.lft AND s2.rgt
where s1.spaceID = 133225
select @path)
from employees e
where e.id = 5
Using that spaceID is guaranteed to give me four rows, and I need them coalesced together, but I can't just use a function (too slow on the scale it would be used), any thoughts?
Can anyone give me the basics of speeding up reports that use queries or views or nested views?
Current reports are now taking over 2 minutes to show.We have thousands and sometimes even millions of records to report against.Queries have 4 and 5 table joins etc.
We are using ASP.NET 2.0 in Visual Studio 2005 and Crystal Reports.
Thanks

Hello.Lets say that there is a table with N rows. now, i want to display the table's data on a web page. one way is to select the whole table and add each row's data to the webpage (something like SELECT * FROM TABLE1).going this way will create a huge page. i want to speared the results over multiple pages - excatly as this forum spread each forum messages over multiple pages.
for this purpose, i need to query Y rows each time, for example, if my table has 20 rows, and say that i want that each page will display 5 rows, then i need to query 5 rows each time. the first 5 rows for the first page, the next 5 rows for the second page and so on...
is there any way to achieve it using an SQL query?
the simplest way is to select the whole table and manaually filter the results. but this way will become slow as the table grows with data... and i dont want to select rows which i wont display anyway.
any suggestions?
Thanks.
I have the got below T SQL query to fetch the matching record
DECLARE @MappingTable TABLE
(
Productname nvarchar(10),
identification_key1 int,
identification_key2 int,
identification_key3 int
[Code] .....
-- result - 'Orange'
This is an exact matching record and straight forward
Is it possible to identify the record using T SQL query based on the following scenarios
1) return the record - If all the three where conditions match
2) if record not found check and return the record where 2 columns values in the where condition match
-- Expected Result for below query: 'Orange', because 2 of the columns in where condition have matching values
SELECT Productname
FROM @MappingTable where identification_key1=1 or identification_key2 =2 or identification_key3 =1
-- result - 'Orange'
I have a dropdown list with checkbox and when I select multiple options and search, its returning only the last selected value in the grid. Here is the code I use it for search. Designation is the column where I bind its values to the checkbox.

</asp:CheckBoxList>
Select Query:SqlCommand cmd = new SqlCommand("select * from AppInvent_Test where Designation= '" + cblGroup.SelectedValue + "'", con);
I have a query which joins multiple tables. This query has suddenly begun to take up to 2 minutes to run (vs. 5-10 seconds previously).
No major change in number of records in the tables (currently about 220,000). When I remove the PK from one of the tables which then forces a tablescan, the query returns to running in 5-10 seconds. If I add the PK back, performance is back to 2 minutes.
Any suggestions short and/or long term?

Hello all. I hope someone can offer me some help. I'm trying to construct a SQL statement that will be run on a Dataset that I have. The trick is that there are many conditions that can apply. I'll describe my situation:
I have about 1700 records in a datatable titled "AISC_Shapes_Table" with 49 columns. What I would like to do is allow the user of my VB application to 'create' a custom query (i.e. advanced search). For now, I'll just discuss two columns; The Section Label titled "AISC_MANUAL_LABEL" and the Weight column "W". The data appears in the following manner:
(AISC_Shapes_Table)
AISC_MANUAL_LABEL W
W44x300 300
W42x200 200
(and so on)
WT22x150 150
WT21x100 100
(and so on)
MT12.5x12.4 12.4
MT12x10 10
(etc.)
I have a listbox which users can select MULTIPLE "Manual Labels" or shapes. They then select a property (W for weight, in this case) and a limitation (greater than a value, less than a value, or between two values). From all this, I create a custom Query string or filter to apply to my BindingSource.Filter method. However I have to use the % wildcard to deal with exceptions. If the user only wants W shapes, I use "...LIKE 'W%'" and "...NOT LIKE 'WT%" to be sure to select ONLY W shapes and no WT's. The problems arises, however, when the user wants multiple shapes in general. If I want to select all the "AISC_MANUAL_LABEL" values with W <= 40, I can't do it. An example of a statement I tried to use to select WT% Labels and MT% labels with weight (W)<=100 is:
Code SnippetSELECT AISC_MANUAL_LABEL, W
FROM AISC_Shape_Table
WHERE (W <= 100) AND ((AISC_MANUAL_LABEL LIKE 'MT%') AND (AISC_MANUAL_LABEL LIKE 'WT%'))
It returns a NULL value to me, which i know is NOT because no such values exist. So, I further investigated and tried to use a subquery seeing if IN, ANY, or ALL would work, but to no avail. Can anyone offer up any suggestions? I know that if I can get an example of ONE of them to work, then I'll easily be able to apply it to all of my cases. Otherwise, am I just going about this the hard way or is it even possible? Please, ANY suggestions will help. Thank you in advance.

Hi there,
I have a MS Access database (mdb) containing the following tables:
Crime
Criminal
CrimeCommitted
Hideout
CriminalType
The Criminal table contains information about each criminal and the CrimeCommitted table contains information about the specific crimes. I've written the following query to return only the latest crime committed by each criminal:
Code Snippet
SELECT Criminal.CriminalID, Criminal.Firstname, Criminal.Lastname, Criminal.Nickname, Criminal.Gender, Criminal.DOB, Criminal.Eyes, Criminal.Complexion, Criminal.Weight, Criminal.Height, Criminal.Build, Criminal.Scars, Criminal.Occupation, Criminal.CrimeOrgID, Criminal.IQ, Criminal.Hideout, Criminal.CriminalType, Max(CrimeComitted.Date) AS Last_Crime_Comitted
FROM Criminal INNER JOIN CrimeComitted ON Criminal.CriminalID=CrimeComitted.CriminalID
GROUP BY Criminal.CriminalID, Criminal.Firstname, Criminal.Lastname, Criminal.Nickname, Criminal.Gender, Criminal.DOB, Criminal.Eyes, Criminal.Complexion, Criminal.Weight, Criminal.Height, Criminal.Build, Criminal.Scars, Criminal.Occupation, Criminal.CrimeOrgID, Criminal.IQ, Criminal.Hideout, Criminal.CriminalType;
This query works fine for obtaining the Criminal table data, but once i've include CrimeCommitted.Country in the SELECT statement, the data returned contained all the crimes committed by each criminal (i just need the latest crime).
The query doesn't work when another table, other than Criminal, is selected. How can i obtain the columns in the CrimeCommitted table in this query?
Yesterday i face a strange SQL Server 2000 behaviour :-(
I had a query that was wrapped inside a stored procedure, as usual.
Suddenly, the stored procedure execution time raised from 9 secs to 80.
So to understand where the problem was i cut and pasted the sp body's into a new query analyzer window an then executed it again. Speed back to 9 secs.
Tried stored procedure again, and speed again set to 80 secs.
Tried to recompile sp. Nothing. Tried to restart SQL Server. Nothing. Tried to DROP & RE-CREATE sp. Done! Speed again at 9 secs.
My collegue asked me "why?", but i had no words. :confused: Do you have any explanation?
