Jul 29, 2015

with c1 As (
select 1 As '1' , 2  As '2' , 3 As '3'

, c2 As (
select 4  As '4', 5  As '5',  6 As '6'
union all
select 1 , 2 ,3 from c1  -- >>>>>  select from c1 here 
) select * from c2 
  union all
  select * from c1 -- >>>>>> and select from c1 here 

According to the query above , I try to reuse the subquery by put  the subquery into 'with cte'  name (c1)  then i select this  2 times .

if I do this way , how many time this subquery (c1) execute ?
if 1 time then this is the right way to reuse this subquery .

Transact SQL :: Get Max Value Using Subquery?

Nov 23, 2015

I have the below data and want to only show records where Response Column has Max date for the commencement date and expiry date under questions column.. For example for tenantcode 52090 the highest Tab value is 2 but this is not correct as there is no associated value in response.

We need to compare all the commencement and lease expiry dates and show only the commencement and lease expiry with the recent dates. Null should be ignored Instead of using Max Tab or Max Modified date would the below logic work? Not sure how to script this.

1. Filter to find Questions containing "Expiry Date"

2. summarise to find the max expiry date per Tenant Code

3. find which records have that maximum expiry

4. join again to find the commencement date

5. union the records from (3) and (4)

6. cross tab

Declare @rent Table
(
TenantCode CHAR(6)
,HHMID CHAR(5)
,Tab CHAR(4)
,FieldNo CHAR(4)
,FieldRowCHAR(10)

Transact SQL :: Subquery Another Table?

Apr 27, 2015

I have a table which is called PneumoniaCareBundleDiagnosisCodes with the fields DiagnosisCode, DiagnosisDesc

I have a another table called dbo_OP_APPOINTMENT_PROCEDURE_PIVOT

With fields Procedure01, Procedure02, Procedure03, Procedure04, Procedure05, Procedure06, Procedure07, Procedure08, Procedure09, Procedure10, Procedure11, Procedure12.

(for info purposes the relationship here is DiagnosisCode = Procedure01, 02, 03 etc)

Is it possible to right a query that shows all records in dbo_OP_APPOINTMENT_PROCEDURE_PIVOT where the DiagnosisCode in table PneumoniaCareBundleDiagnosisCodes appear in any of the Procedure01, 02, 03 fields etc.

If I was using an IF statement the logic i would right it as follows:
IF dbo_OP_APPOINTMENT_PROCEDURE_PIVOT.Procedure01
IS IN PneumoniaCareBundleDiagnosisCodes.DiagnosisCode OR
IF dbo_OP_APPOINTMENT_PROCEDURE_PIVOT.Procedure02

Transact SQL :: Get Subquery To Eliminate Malformed Date?

Jun 30, 2015

I have the following query.

SELECT a.Line_Number as Line_Number,
Cast(a.election_effective_date as DATE) as election_effective_date,
Cast(a.Plan_Year_Effective as DATE) as Plan_year_Effective
FROM (SELECT aa.* FROM TEMP_Validation aa WHERE IsDate(aa.Plan_Year_Effective) = 1 AND IsDate(aa.election_effective_Date) = 1) a
Where Cast(a.election_effective_date as Date) Not Between Cast(a.plan_year_effective as Date)
and DATEADD(DD,-1,DATEADD(YY,1,Cast(a.plan_year_effective as Date)))

There is a malformed date in the Temp data, at line 4932.  This is why I created a subquery that checks if the plan year and election effective dates are dates using the "IsDate" function.  However, when I execute this I get the error "Conversion failed when converting date and/or time from character string".  If I eliminate line 4932 the error no longer occurs.  Somehow line 4932 is not being eliminated in the subquery, except if I run JUST the subquery it will not include line 4932.  What am I doing wrong on these queries and how can I correctly get the subquery to eliminate the malformed date?

Transact SQL :: Query Works Even If Column Not Exists In Subquery

Jul 23, 2015

When I execute the below queries it works perfectly where as my expectation is, it should break.

Select * from ChildDepartment C where C.ParentId IN (Select Id from TestDepartment where DeptId = 1)
In TestDepartment table, I do not have ID column. However the select in sub query works as ID column exists in ChildDepartment.  If I do change the query to something below then definately it will break -
Select * from ChildDepartment C where C.ParentId IN (Select D.Id from TestDepartment D where D.DeptId = 1)

Shouldn't the default behavior be otherwise? It should throw error if column doesnt exists in sub query table and force me to define the correct source table or alias name.

create table TestDepartment
(
DeptId int identity(1,1) primary key,
name varchar(50)
)
create table ChildDepartment
(
Id int identity(1,1) primary key,

Adding Product Of A Subquery To A Subquery Fails?

Jul 6, 2014

I am trying to add the results of both of these queries together:

The purpose of the first query is to find the number of nulls in the TimeZone column.

Query 1:

SELECT COUNT(*) - COUNT (TimeZone)
FROM tablename

The purpose of the second query is to find results in the AAST, AST, etc timezones.

Query 2:

SELECT COUNT (TimeZone)
FROM tablename
WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST')

Note: both queries produce a whole number with no decimals. Ran individually both queries produce accurate results. However, what I would like is one query which produced a single INT by adding both results together. For example, if Query 1 results to 5 and query 2 results to 10, I would like to see a single result of 15 as the output.

What I came up with (from research) is:

SELECT ((SELECT COUNT(*) - COUNT (TimeZone)
FROM tablename) + (SELECT COUNT (TimeZone)
FROM tablename
WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST'))

I get a msq 102, level 15, state 1 error.

I also tried

SELECT ((SELECT COUNT(*) - COUNT (TimeZone)
FROM tablename) + (SELECT COUNT (TimeZone)
FROM tablename
WHERE TimeZone NOT IN ('EST', 'MST', 'PST', 'CST')) as IVR_HI_n_AK_results

but I still get an error. For the exact details see:

[URL]

NOTE: the table in query 1 and query 2 are the same table. I am using T-SQL in SQL Server Management Studio 2008.

Can We Reuse SqlParameter's?

Jul 10, 2004

Hi,

I am getting the following error:

The SqlParameter with ParameterName '@pk' is already contained by another SqlParameterCollection

If I could work out what code to post I would, but I can say that I am managing my Sql data in my code by caching small arrays of SqlParameter objects as pulled from the database. If I need to update the DB I change the cached SqlParameter and re-insert it. If I perform a SELECT I check the cache first to see if I already have the SqlParameter.
However, currently, I am experiencing the above error when performing a select, then later an update, followed by another update.
Would I be correct in saying that a SqlParameter object can only be used once for a database operation and should be discarded? Would I be correct if I said that the SqlCommand object should be discarded? I am barking up the wrong tree entirely?

Distressed in DBLand,
Matt.

How Can I / Should I Reuse SqlCacheDependency? Thanks

May 1, 2006

I can create a SqlCacheDependency, and link it to a cached item in httpcontext cache. When something change, it will remove the cached item from the cache. I think I have to redo the process when that happens - prepare sql command, create SqlCacheDependency and insert the item into cache. Now I only need a notification from my SQL when something changes in one of my table, I don;t need read anything from db, and I think I should find a way to not recreate the SqlCacheDependency object everytime?
any suggestion?

Reuse Calculated Values

Nov 14, 2006

What is the best code pratice to use do the following code,

SELECT
fo.no as LNum,
fo.name as LName,
sum(CASE fo.docnome WHEN "In" THEN fo.etotal ELSE 0 END) as In1,
sum(CASE fo.docnome WHEN "In2" THEN fo.etotal ELSE 0 END) as In2,
sum(In1+In2)/10 as inDec,
from fo group by fo.no,fo.name order by fo.name

instead of

SELECT
fo.no as LNum,
fo.name as LName,
sum(CASE fo.docnome WHEN "In" THEN fo.etotal ELSE 0 END) as In1,
sum(CASE fo.docnome WHEN "In2" THEN fo.etotal ELSE 0 END) as In2,
((sum(CASE fo.docnome WHEN "In" THEN fo.etotal ELSE 0 END))+sum(CASE fo.docnome WHEN "In2" THEN fo.etotal ELSE 0 END)))/10 as inDec,
from fo group by fo.no,fo.name order by fo.name

I cant use functions and procedures. Is there any better and cleaner way to code this, reusing the calculated values?

Stored Procedure Reuse

Jul 23, 2005

I wonder if there is a solution for this in SQL 2000 (or do I have towait for SQL 2005)?I am currently in the middle of developing a 'Yahoo' style portal whichwill be rolled out in about 20 or so countries. I have set up in SQLServer one database per country. All the portals have the samefunctionality - but show different data.Is it possible to have a single database which holds storedproceedures, functions and views and have the individual countrydatabases use these?Note: I want to avoid using EXEC sp_executesql.I look forward to some good news on this! Thank you in advance.Dadou.

Cannot Reuse Database Name After Deleting Old One

Apr 19, 2008



Hi. I'm starting to try out LINQ to SQL, and so I'm using SQL Express (on Vista) to experiment. My problem is that once I create and delete a database, I can never use the name again. If, after deleting the old database, I try to create another one with the same name (say Acct1), I get "Create failed for Database 'Acct1'. An exception occurred while executing a Transact-SQL statement or batch. The logical file name "Acct1" is already in use. Choose a different name. Error: 1828"

I am trying to create the database in SQL Server Management Studio Express. That database name does not appear in the list of databases: there is only AdventureWorks and the system databases. The .MDF and .LDF files have been deleted. Not just sent to the recycle bin, but permanently deleted.


I have already used up Acct1, Acct2, and Acct3, just to try out different scenarios. Each time, I delete the old database before trying to create a new one with the same name, but I am forced to always supply a new, different name. I have checked the directory with hidden files and system files showing to be sure there is no old file lurking there somewhere.


Is there a way to delete these old "logical file names"? I can't even find any reference to their existence except for the message that says they are already in use.

Reuse Of Conversation Handles

Nov 26, 2007



I have read the articles posted online concerning different dialog reuse strategies. Most of them create a new table in the sender to hold dialog ids. I was wondering what is wrong, if anything, with the following approach:




Code Block
declare @dlg uniqueidentifier
select top 1 @dlg = conversation_handle from sys.conversation_endpoints where state IN ('CO')
if @dlg is null
begin
begin dialog conversation @dlg
from service [tcp://SFT3DEVSQL01:4022/TyMetrix360Audit/DataSender]
to service '//TyMetrix360Audit/DataWriter','386DDD04-7E55-466A-BE83-37EFC20910B9'
on contract [//TyMetrix360Audit/Contract] with encryption = off;
end
;send on conversation @dlg
message type [//TyMetrix360Audit/Message] (@msg)





Here I simply select a conversation handle directly from the sys.conversation_endpoints table. Can anyone see any issues with this approach?

Thanks in advance....

Reuse Of Field Aliases

Jan 3, 2007

I have been working with SQL for quiet a while but think this perhaps is a very basic question that has always escaped me:

At my work I was exposed to both, MS SQL Server 2000 and Sybase Adaptive Server Anywhere/Sybase SQL Anywhere.

Under Sybase I was able to use aliases in other calculations and filters but i have never been able to do the same with SQL.

Example:
In Sybase I can write this:

Select Price * Units as Cost Cost * SalesTax as TotalTaxFrom Invoice Where TotalTax > 3.5
However if i want to do this in MS SQL 2000 i have to go trough


Select
Price * Units as Cost
Price * Units * SalesTax as TotalTax
From Invoice
Where (Price * Units * SalesTax) > 3.5

In the long run this is costing me a lot of code redundancy, not to mention a debugging nightmare. Is there a way to replicate this alias usage in MS SQL Server?

Reuse Of Report Elements

Jun 5, 2007

I am working on a project developing a fairly large number of reports with a team of developers. Many of these reports have common elements and code, such as common headers with user-selectable colors. Additionally, many of the common parts of the reports are at mockup stage currently, and many features will have to be added to the reports as time goes on.



We're attempting to create a generalized framework that will minimize the duplication of effort as we develop these reports, and as we go back and modify or fix them later.

What is the best way to approach this?



My first attempt was to create a report template and base all the reports off of the same template. That was fine for the first pass, but as we need to make changes later, they will not be propagated to the already existing reports.



My second attempt was to have each componant of that template reference a subreport, so that changes to the actual report template will be minimized as we go forward. This works great for minimizeing work, but it appears that you lose many features with the use of subreports, and there seems to be a pretty serious performance impact as well. I have posted about one such issue here: Pagination



If anyone has pointers about how to go about this, and where I should start, they would be greatly apreciated!

Reuse Numbers In Identity Column

Mar 4, 2008

Hello,

I have an ID column which is an Identity column, and it counts from 1 upwards.

If I have 10 records, I have ID's number 1 to 10.
If I then add another record, it will give the ID number 11.

Imagine I then delete ID number 9
Is it possible to get the next record I create to take number 9 instead of 12 ?
