Multi-column Index Vs Single Column Indexes
Aug 14, 2007Hi,Would like to know the performance differenece between Multi-columnIndex vs Single Column Indexes. Let's say I have a table with col1,col2, col3 along with a primary key column and non-indexed columns.In queries, I will use col1, col2, and col3 together and some timesjust one or two of these three columns. My questions is, should Icreate one index contains col1, col2, and col3, or create 3 seperatedcolumns. I.e. each column has its own index. Any performancedifference?Thanks a lot.

Comparing Nullable Column With Int
Sep 20, 2007
Hi,
I have a table name bla.
PKEY id, int, NOT NULL
group, int
name, string, NOT NULL
how do I compare them with int?
for example the following data.
1, NULL, 'freelance'
2, 1, 'group1'
3, 2, 'group2'
select * from bla where group<>1 <-- this fails?
What is the proper SQL Statement for this?

Comparing Column Values Among 2 Or More Rows
Jun 29, 2012I've been working with T-SQL in a MSSQL Server Management Studio (2005) for about a week now. I've been trying to convert some horribly written VB code from a MS Access DB over to SQL so it can be automated on a SQL backend.
Most of the learning process and coding has gone surprisingly well. The problem is with comparing some data to determine which one needs to be flagged.
Three tables to note in bold, with notable fields in italics below them:
EmployeeData
HRID (identity)
ResourceAllocation
ID (identity)
[Last Name] (linked to HRID)
Project
[Resource Start Date]
[Resource End Date]
[Percent Utilization]
tblHCvalues
RAID (linked to ResourceAllocation.ID)
a monthyear and quarteryear for every month and quarter from 2012-2014. IE january12, february12, 1q12, 2q13, etc...
And yes, there are probably a thousand ways to optimize that tblHCvalues, but I'll ask about that later. Just work with the structure I have
Here's how it works: Each employee's data and unique HRID is in the EmployeeData tableAn employee can be on one or multiple projects at any timeThose projects are stored per project in the ResourceAllocation table with a link to the Employee's HRID, and all the other information listed aboveEven though an employee might be on two projects, they can only count for headcount on one project.
We use rules that compare the percent of work being done on a project, and the start and end dates of the employee (resource) on that project to determine which project should be counted for Headcount. The code uses a cursor to go through each HRID, and then pull up all the ResourceAllocation records associated with it.Run the rules to determine which ResourceAllocation record counts toward headcountA stored procedure then runs that fills out the tblHCvalues in the way we want for the project we want
All of it works, except for the rules that compare the things, so that's what I want to focus on in this thread. How do I write these rules:
Here are the rules, and they should work for any number of multiple resource allocations for one employee:
Choose the ResourceAllocation with the greatest [Percent Utilization]If the top ResourceAllocations have equal [Percent Utilization], choose the ResourceAllocation with the earliest [Resource Start Date]If the [Percent Utilization] and the [Resource Start Date] are equal, choose the latest [Resource End Date]If all three fields are equal, choose the first ResourceAllocation (aka, screw it and pick one at random)
I'm sure I could use a bunch of IF statements to compare it all, but even that is complicated to think about. There has to be an easier way, right?
T-SQL (SS2K8) :: Comparing Column Values In Same Table
Jun 16, 2014How to resolve the below task
create table #temp ( idx int identity(1,1), col1 int, col2 int )
Here i want a flag success or fail on basis of below conditions.
I need to take all the col1 values and then i need to compare to each other.
if any difference found, i need to check difference more than 30, then it should raise the flag as "Failure".
if all the col1 values are ok , then we need to check Col2 values same as above.
--case 1
insert into #temp(col1,col2)
select 16522,18522
union all
select 16522,18522
union all
select 16582,18522
--select * from #temp
--truncate table #temp
Because of difference in col1 values . the value of flag should be fail.
--case 2
insert into #temp(col1,col2)
select 16522,18522
union all
select 16522,18522
union all
select 16522,17522
Here also the col1 is ok but col2 values have difference so it should be Fail.
Otherwise it should be success.
Comparing A Column List Split To A Table.
Jul 23, 2005Let me see if I can explain my situation clearly.I have a table with the columns:answer_id, question_id, member_id, answer- answer_id is the primary key for the table.- question_id relates to another table with questions for a user. Thetable holds the question and the possible choices in a varchar fieldseparated by a delimiter.- member_id is self-explanatory- answer is a varchar field of all the choices the user selected,separated by a delimiter.Here is my problem.I am trying to search all members that have answered, say, question_id= 2 where they selected 'brown' as one of their choices.i can do this if they selected ONLY that item, but not multiple items.The problem is this portionanswer in(select valu from dbo.iter_intlist.....I need this to be something like....function_to_return_all_separated_answers(answer) in(select valu from dbo.iter_intlistThe current way, it is only returning members that have an answer'Brown', not 'Brown, Blue' in their answer field.

SQL Server 2008 :: Comparing A Column Between Two Tables With A Wildcard?
Aug 9, 2015I have a table containing records of criminal convictions. There are over 1M records and the only change is additions to the table on a monthly basis. The two columns I need to deal with are convicted.NAME and convicted.DOB
I have a second table that has 2 columns. One is the name of the defendant and the other is the birth date. This would be monitor.NAME and monitor.DOB
There are no primary keys or any other way to join the tables for this search I want to do.
I would like to be able to put a name in the "monitor" table and run a query to see if there is a match in the convicted table.
The problem I am having is middle initials or names. If I want to monitor.name = 'SMITH JOHN' it will return the results fine. The problem I am having is if the conviction is in the database as 'SMITH JOHN T', or 'SMITH JOHN THOMAS'.
How can I use the monitor table with a 'LASTNAME FIRSTNAME' and return results if the convicted table has a middle initial. I tried with a JOIN:
select distinct convicted.*
from convicted
join monitor
on monitor.name like convicted.defendant
and monitor.birthdate = convicted.dob
SQL Server 2012 :: Implicit Conversion Comparing INT Column To 0?
Sep 15, 2015In a stored procedure, the following code is causing a huge read and CPU load when it really shouldn't. The @IDParameter below is coming in as a parameter to the proc.
Here's the snippet of code where the problem is coming in:
DECLARE @ID INT;
SET @ID = (SELECT ID From OtherTable WHERE FKID = @IDParameter);
SELECT COUNT(*)
FROM LargeTable
WHERE MostlyZeroID = @ID AND MostlyZeroID > 0Most (90+%) of the MostlyZeroID rows are 0 (hence the name) but regardless of distribution this should evaluate with minimal work on SQL Server's part to 0. However, when this was run, it is using a ton of CPU and doing a ton of Reads as it seeks through the entire index. When I look at the execution plan, I see under the seek predicate a Scalar Operator(CONVERT_IMPLICIT(int,[@1],0)) which is what is destroying the performance.
I've confirmed that the MostlyZeroID column in the LargeTable is defined as an INT NOT NULL. I also tested the scenario outside the stored procedure without any variables as the following to make sure it wasn't some kind of strange parameter sniffing scenario:
SELECT COUNT(*)
FROM LargeTable
WHERE MostlyZeroID = 0 AND MostlyZeroID > 0
However, this query also did the implicit conversion. I then tried this out on a temp table populated with a similar number of records (100 million) with a similar distribution and I didn't get the implicit conversion (I got a constant scan as I would've expected) when I did this:
SELECT COUNT(*)
FROM #TestTable
WHERE MostlyZero = 0 AND MostlyZero > 0
I also tried the same on several other tables that are set up similarly (large amount of zeros in an INT column) and I always got a constant scan and didn't do an implicit conversion.
why the query engine is interpreting this 0 as something other than an INT and doing an implicit conversion when getting the count in the scenario above? What can be done to protect against it? In the above scenario, an IF @ID > 0 statement was placed before the code including the count since there was no reason to even run the code if the @ID was equal to zero.
Transact SQL :: Comparing Previous Records Based On Each ID Column
Aug 21, 2015I have a scenario to compare previous records based on each ID columns. For each ID, there would be few records, I have a column called "compare", We have to compare all Compare 1 records with Compare 0 Records. If Dt is lesser or equal to comparing DT, then show 0. Else 1
We always only one Compare 0 records in my table, so all compare 1 columns will compare with only one row per ID
My tables look like
Declare @tab1 table (ID Varchar(3), Dt Date, Compare Int)
Insert Into @tab1 values ('101','2015-07-01',0)
Insert Into @tab1 values ('101','2015-07-02',1)
Insert Into @tab1 values ('101','2015-07-03',1)
Insert Into @tab1 values ('101','2015-07-01',1)
Insert Into @tab1 values ('101','2015-06-30',1)
Insert Into @tab1 values ('102','2015-07-01',0)
Insert Into @tab1 values ('102','2015-07-02',1)
Insert Into @tab1 values ('102','2015-07-01',1)
select * from @tab1
1.) In the above scenario for ID = '101', we have 5 records, first record has Compare value 0, which mean all other 4 records need to compare with this record only
2.) If Compare 1 record's Dt is less or equal to Compare 0's DT, then show 0 in next columnÂ
3.)Â If Compare 1 record's Dt is greater than Compare 0's DT, then show 1 in next columnÂ
My expected result set should be like ....

--drop table #tab1
insert into #tab1 values (1000, 100,'Tom', 2500, '10/01/2012')
insert into #tab1 values (1001, 101,'Bat', 1550, '08/11/2012')

insert into #tab1 values (1010, 104,'Sim',200, '04/21/2013')
[code]....
i would like to get 4 columns output
how to get sumofshares (#tab1) and TotalOutStanding(#tab2) summ up with these values,
MasterKey (#tab1) and IssueKey (#tab2) are like primary key and foreign key
so the request is
need to calculate, sumofshares (#tab1) and TotalOutStanding(#tab2) as below
1)ShareBenefist = U and year( request_dat) in (2012 , 2103) and (Name for 2012 should match with 2013 name and 2012 Acctno should match with 2013 accounno) in (#tab1)
then '2012 and 2013 accts UN Veriverted'
2)ShareBenefist = V and year( request_dat) in (2012 , 2103) and (Name for 2012 should match with 2013 name and 2012 Acctno should match with 2013 accounno) in (#tab1)
then '2012 and 2013 accts Veriverted'
3)ShareBenefist = N and year( request_dat) in (2012 , 2103) and (Name for 2012 should match with 2013 name and 2012 Acctno should match with 2013 accounno) in (#tab1)
then '2012 and 2013 accts NONVERT'
4)year( request_dat) =2102 and Name and Acctno not match with 2013 account name and acctno (#tab1)
then '2012 last year accounts'
5)year( request_dat) = 2013 and Name and Acctno not match with 2013 account name and acctno (#tab1)
then '2012 This year accounts'
for ex 1) the below accounts in #tab1 has both 2012 and 2013 and acctno same in both years and name is same in both years so it is condired as
insert into #tab1 values (1012, 100,'Tom',800, '08/22/2013')
for ex 2)
insert into #tab1 values (1013, 101,'Bat',550, '09/15/2013')
for ex 4) 2012 records there is not match acctno and name in 2013 recods
insert into #tab1 values (1002, 102,'Kit', 1600, '06/12/2012')
for ex 5) 2013 records there is no match of name and acct no with 2012 records
insert into #tab1 values (1010, 104,'Sim',200, '04/21/2013')
insert into #tab1 values (1014, 100,'Pet',200, '02/21/2013')
insert into #tab1 values (1016, 110,'Sun',800, '03/22/2013')
insert into #tab1 values (1017, 111,'Bet',550, '12/15/2013')
Expected Results (just for format)
AcctTypeDescription,SumofShares, OtotalutStand
'2012 and 2013 accts UN Veriverted',2700,234
'2012 and 2013 accts Veriverted' ,2890,234
'2012 and 2013 accts NONVERT' ,4533,325

Identity Column And Indexes
Sep 21, 1999The largest table in the database is not referenced by any other table. Primary key is identity column. I know that I shouldn’t make clustered index on that column, but what if I don’t index that column at all? Will it be some negative consequences of that decision?

Multiple Indexes On The Same Column
Jan 21, 2008Hi All
I have a table with indexes as follows
license_detail_prim
clustered, unique located on PRIMARY
component_id, license_id
LICENSE_DTL_IDX_LICENSE_ID
nonclustered located on PRIMARY
license_id
PK__license_dtl__6EB64F9B
nonclustered, unique, primary key located on PRIMARY
component_id, license_id
XIF39license_dtl
nonclustered located on PRIMARY
license_id
from the above, it is evident that multiple indexes have been created on the same columns
What is the side effects of havins such table design.

Column Names
Dec 27, 2005At my work, we are upgrading a number of MS Access 2000 databases to SQL Server 2000. Many of the columns have names that do not follow the rules for Identifiers. For example there are columns with a numeric names 1,2,3,4,5,6,7,8,9. There are also columns with a hyphen in the name and columns that begin with a number and not an underscore or an alpha character. Plus there are columns with names like first, last, position, etc. (There was also columns with reserved words used as the names. I have changed those column names in the databases that I have already converted) Will leaving these names alone create a problem? The database serves as the backend to ASP pages.

Integration Services :: Comparing Variable Value With Flat File Column In Precedence Constraint
Aug 4, 2015I am creating one SSIS package where my source is oracle. I have transferred the data from Oracle to flat file as per client requirement.I have to create single package for 2 country 1 is US and another is CANADA Columns are below
ZONE_ID,
ZONE_NAME
Zone Id having data like 10001,10002,10003,20001,2002,2003
Where zone_id start with 1000 is US Zone and Zone_Id start with 2000 is Canada Zone.
For US:
1. Load geography data from DB tables into flat files
2. Load geography data from flat files to Spectrum DB tables
For Canada:
1. Load geography data from DB tables into flat files
2. Load geography data from flat files to Spectrum DB tables
Now I want to look from flat file if Zone_id start with 1000 then it must go to US_DFT and if Zone_id start with 2000 then it must go to CANADA_DFT.

If this is an ignorant question I do apologize but heres my scenario: I have a table with columns of the day, for instance: Monday_hasData (bit)Monday_DataAnd what I want to do is essentially pass in "Monday" as a parameter and rather than doing an If statement on each row, I would like to just like to do something like assign @dayCheck + "_hasData" to a variable and then use @dayCheck as part of my query. Is this possible or am I going to have to have 7 cases? Thank you for any input,Chance
