Not All Where Conditions Required
Mar 17, 2008
I am trying to do a select with the closest match.
Code Snippet
CREATE TABLE [#Person]
(
[PersonId] tinyint IDENTITY(1,1) NOT NULL
,[Height] char(2) NOT NULL
,[Weight] char(3) NOT NULL
,[Age] varchar(3) NOT NULL
,[HairColor] varchar(7) NOT NULL
,[EyeColor] varchar(7) NOT NULL
);
INSERT INTO [#Person] ([Height],[Weight],[Age],[HairColor],[EyeColor])
VALUES ('71', '150', '23', 'Brown', 'Blue');
INSERT INTO [#Person] ([Height],[Weight],[Age],[HairColor],[EyeColor])
VALUES ('70', '190', '22', 'Blonde', 'Brown');
INSERT INTO [#Person] ([Height],[Weight],[Age],[HairColor],[EyeColor])
VALUES ('69', '140', '20', 'Black', 'Brown');
INSERT INTO [#Person] ([Height],[Weight],[Age],[HairColor],[EyeColor])
VALUES ('65', '150', '21', 'Brown', 'Green');
SELECT * FROM [#Person]
WHERE
([Height] > '66' AND [Height] < '72')
AND ([Weight] > '150' OR [Weight] < '180')
AND ([Age] > '20' OR [Age] < '25')
AND ([HairColor] IN ('Brown', 'Blonde', 'Black'))
AND ([EyeColor] IN ('Blue', 'Brown', 'Green'));
DROP TABLE [#Person];
This simple example works great. But what if I wanted everybody who met 4 of the 5 conditions? I tried to think of a counting solutions, and then order by the count but I could quite get there. Any help would be greatly appreciated. My live data is actual sales records with 20 some odd record types. I am hoping any solutions I find will scale well.

An automatic failover set exists. This set consists of a primary replica and a secondary replica (the automatic failover target) that are both configured for synchronous-commit mode and set to AUTOMATIC failover.Configured the both AG Group database automatic failover and synchronous-commit mode.But automatic Failover failed also Cluster service not started automatically at Node2. It got connected through AO Listerner after starting Node1. As below SQL Error log during shutdown Node1

My question is fairly simple. When I join between two tables, I always use the ON syntax. For example:
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId)
No problems there. However, if I then decide to further filter the selection based on some trait of the UserRole, I have two options: I can add the condition as a WHERE statement, or I can add the condition within the ON block.
--Version 1:
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId)
WHERE
UserRoles.Active = 'TRUE'
-- Version 2
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId
AND UserRoles.Active = 'TRUE')
So, the question is, which is faster/better, if either? The Query Analyzer shows the two queries have the exact same execution plan, which makes sense, since they're both joining the same tables. However, I'm wondering if adding the condition in the ON statement results in fewer rows the JOIN statement initially needs to join up, thus reducing the overall initial size of the results table before the WHERE conditions are applied.
So is there a difference, performance wise? I imagine that if Users had a thousand records, and UserRoles had 10 records, then the JOIN would create a cartesian product of the two tables, resulting in 10,000 records in the table before the WHERE conditions are applied. However, if only three of the UserRoles is set to Active, would that mean that the resulting table, before applying WHERE conditions, would only contain 3000 records?
Thanks for whatever information you can provide.

I have a table
CREATE TABLE [dbo].[CmnLanguage]( [Id] [char](2) NOT NULL CONSTRAINT PkCmnLanguage_Id PRIMARY KEY, [EnglishName] [varchar](26) NOT NULL, [NativeName] [nvarchar](26) NOT NULL, [DirectionType] [smallint] NOT NULL, [IsVisible] [bit] NOT NULL, [CreatedDateTime] [datetime] NOT NULL DEFAULT GETDATE(), [ModifiedDateTime] [datetime] NULL)
We will use these 3 queries
select * from CmnLanguage where IsVisible = 0select * from CmnLanguage where IsVisible = 1select * from CmnLanguage
I want to make a method which handles these queries.
But at the back end on Stored Procedures
We have to write 3 queries
Which I don't want to do.
I want to minimize the queries and conditions
and want to just write one for these 3
Can any one do it?

Folks,
I'm having some real problems using the OR condition in a very simple SQL statement and could use your help or insight on where the problem lies, or perhaps a workaround.
I have a large flat table in a SQL 7 database with 10 million + records called "HISTORY". I have not installed either service pack 1 or 2. I'm attempting to run a query that references the following four fields which are all non-clustered keys:
EQUIPMENT_NO TEXT 12
CHASSIS_IN TEXT 12
CHASSIS TEXT 12
SVC_DATE_TIME SMALLDATETIME
Here's the SQL statement:
SELECT * FROM HISTORY WHERE (HISTORY.EQUIPMENT_NO = 'XYZ123' OR HISTORY.CHASSIS = 'XYZ123' OR HISTORY.CHASSIS_IN = 'XYZ123') AND SVC_DATE_TIME >= '01/15/00 00:00:00 AM' AND SVC_DATE_TIME <= '02/28/00 23:59:59 PM'
ORDER BY EQUIPMENT_NO
This query takes 11 min. 5 sec. inder the Query Analyzer and ultimately returns the 31 desired records.
If you remove the SVC_DATE_TIME criteria, about 350 records are returned in a matter of seconds. I've also tried variations on the date syntax such as '01/15/00', etc. with no change in the amount of time to execute.
Other queries such as a simple AND condition combining EQUIPMENT_NO and SVC_DATE_TIME are snappy.
Are there known problems/bugs with "OR" conditions in queries that anyone is aware of, particularly with parentheses; am I composing this query incorrectly? Is there some alternate syntax that would work as expected? I can't see where the query shouldn't execute quickly as expected, particularly with all indexed fields involved. I'm stumped! Lend me your expertise. Thanks much.

Hai frns small help needed.
I have a table called sample and i have the following requirement. i.e i need sum(credit) group by ssn no.
One special condition is as follows:
For each distinct ssn if "flag" has the same CX value,then out of all the records with the same CX value, the highest "credit" value is added to the sum for that "ssn" and the rest are ignored.
If while adding "credit" to the sum and if "credit" value is equal to zero then "sum" value is used for summing else "credit" value is used.
Can any one help me out in trying this logic. I have tried but i could'nt able embed the conditions inbetween the Sql statetment.
Here is the query is used
select * from sample
idssncreditflagsem
11010C90
21014C93
31014.5C92
41013.5C11
51024.2C33
61030C12
select ssn,flag,sum(case credit when 0 then sem else credit end) as sum from sam2
group by ssn,flag
ssn flag sum_val
101C13.5
103C12.0
102C34.2
101C98.5
The above output is wrong one.
Expected output
101 4.5+3.5=8.0
102 4.2
103 2.0
Any help would be appreciated
Regards,

Code:
Drop table #table
Drop table #table_with_groupid
-- Prepare test data
CREATE TABLE #table
([Admissions_key] bigint NOT NULL PRIMARY KEY,
MRN nvarchar(10) NOT NULL,
[Code] ....
How can I compare dates with conditions. I only want to Mark C where the difference between adm_datetime and prevsep_datetime is <= 1 otherwise E as well
where datediff(MINUTE,tg.adm_datetime,tg.pre_sep_date)< =1 ??
is it correct ? where should I put this to implement correctly ?

I have the following:
MAX(Vernum) AS test,
MAX(Case WHEN A2.AttrID = 2 AND A2.DefID = 10057945 THEN A2.ValStr END) AS TYPE_DOCUMENT
This works not perfect. In many cases I have more then one row and my query takes the max value of column Valstr. Thats is not exactly what I want. I'd like to have the value of Column Valstr of the row where column Vernum has the maximum value.
I've tried many things like:
MAX(Vernum) AS test,
MAX(Case WHEN A2.AttrID = 2 AND A2.DefID = 10057945 AND A2.Vernum=test THEN A2.ValStr END) AS TYPE_DOCUMENT
OR
MAX(Vernum) AS test,
MAX(Case WHEN A2.AttrID = 2 AND A2.DefID = 10057945 AND A2.Vernum=MAX(A2.Vernum) THEN A2.ValStr END) AS TYPE_DOCUMENT

1. Are stored procedures WITH ENCRYPTION slower than the ones withoutencryption?2. Should i put most restrictive conditions first or last in WHERE? Inwhich order does MSSQL execute conditions? Or MSSQL determents whatwould be best and does not bother with the way i sorted conditions?for example:SELECT *FROM [users]WHERE[user_id] = 1 AND[baned] = 0Is "[user_id] = 1" or "[baned] = 0" going to be executed first?

Hi,
I want to create a trigger that that is invoked when a certain condition is fulfilled. For instance:
I have 2 tables, PS and US with similar table structure. PS table contains a column called 'status'. Whenever the status column is updated from 2 to either 23, 24, 25 or 26, a new row, which contains the same data within the updated row of PS, will be inserted into the table US.
Can this be done? Thanks in advance.

I can't figure this out for the life of me. Wanted to know if it's possible to select certain date conditions in a query, then later reference those conditions and to only select the max of them.
I need to do this dynamically as I do not know what the max value is. I've provided an example below:
Select var1
From table1
where
(
(Date1 = '11/30/2005')
OR
(Date1 = '12/31/2005')
)
and Date1 = (Max of previously selected values e.g. '12/31/2005')
What I can't figure out is how to dynamically retrieve the max of 11/31/2005 and 12/31/2005. Any ideas are greatly appreciated.

I have an issue accumulating a value based on certain conditions:
I need to sum up the days column as you can see table below. The sum is based on the StartNewFlag.
When the flag is 1, I need to start a new sum from zero, else I need to accumulate to the previous rows.

I have a table where when an employee works LEAVE1 and LEAVE2 paycodes on the same day then in the new column called 'FLAG' we need to put a 1 for LEAVE1 and a 2 for LEAVE2, when these paycodes are not there on the same day then flag will be NULL as for other paycodes.
Tried using the CASE statements but it always puts a 1 or 2 for the respective paycodes regardless of the fact whether they were together on the same day or not.
WITH SampleData (PERSON,TRANSACTDATE, STARTDATE, END_DATE, IN_PUNCH,OUT_PUNCH,HOURS, PAYCODE) AS
(
SELECT 1234,'08/03/2015','08/03/2015','08/03/2015', '06:00','09:00','3', 'REG1' UNION ALL
SELECT 1234,'08/03/2015','08/03/2015','08/03/2015', '09:00','13:00','4','REG2' UNION ALL
SELECT 1234,'08/04/2015','08/04/2015','08/04/2015', '09:00','13:00','4','LEAVE1' UNION ALL
SELECT 1234,'08/04/2015','08/04/2015','08/04/2015', '14:00','16:00','2', 'LEAVE2'UNION ALL
SELECT 1234,'08/05/2015','08/05/2015','08/05/2015', '08:00','09:00','1', 'LEAVE1'UNION ALL

I have a Vehicle/Driver Inspection Database and I'm trying to create a Traffic Violation Point System, its a system when drivers commit certain traffic offences they will incur driving-offence points.
System: The points for violations that all occurred within the last 12 months of ONE ANOTHER are added together to calculate point total. If the accumulated points is reached 14 points driver is suspended the points will be REMOVED or minus 14 points after the suspension has been served.
Example:
Date of Offence - Number of Points
Aug. 6, 2013 - 6
Feb. 4, 2014 - 4
Apr. 25, 2014 - 4
- 2
May 8, 2014 - 2
Explanation:
On April 25, 2014 two offences incurred and from (Aug 6, 2013 - Apr. 25 2014) 14 points have accumulated (6 + 4 + 4) and suspension is carried out then 14 points is removed. The 2nd offence on Apr. 25, 2014 will be carried forward and added to May 8, 2014 points (total 4 points).
Below are DB Tables:
tbl_Driver
DriverID DriverLicense FirstName LastName
tbl_Event
EventID EventTIme DriverID CarID
tbl_EventViolation
EventViolatinID EventID ViolationID Status (1 = no, 2 = yes radio buttons)
tbl_Violation
ViolationID ViolationName Points
tbl_ViolationClass
ViolationClassID ClassName
I made an SQL Code but to sum the accumulated points only but not the whole condition. See below:
SELECTa.DriverId,
a.DriverLicense,
a.FirstName + ' ' + a.LastName as DriverName,
a.FirstName,
a.LastName,
a.DriverMobileNo1,
[Code] .....

Hello,
I would like some assistance with some code that I am attempting to write. I have one column (Mgr1FullName) that contains different values. I want it to show me all the people who has a manager name as Unavailable, Null, or blank.
Example Code:
--------------------------------------------------------------------
select uuid_hdr.id,
uuid_hdr.bizrightid,
uuid_hdr.fullname,
uuid_hdr.mgr1fullname,
uuid_dtl.role,
uuid_dtl.application,
uuid_dtl.dateremoved,
uuid_dtl.userid
from uuid_dtl
inner join uuid_hdr
on uuid_dtl.hdr_id = uuid_hdr.id
where uuid_dtl.dateremoved is Null and
uuid_dtl.application = 'SAPRET'and
uuid_hdr.mgr1fullname = 'Unavailable'or
uuid_hdr.mgr1fullname is Null or
uuid_hdr.mgr1fullname = ' ' and
uuid_dtl.userid not like 'prodsup%' and
uuid_hdr.bizrightid not like 'prodsup%' and
uuid_dtl.role not like 'z:m_genuser_vendor'
-------------------------------------------------------------------
Should I use ORs or ANDs? I will face this same problem with the ROLE column.
Thanks for all and any help.
