I have a requirement (motivated by a SOX thing) that is just giving me
fits. I know it should be easy and I'm probably overthinking it, but I
just can seem to find the best way to get where I need to go.
I have some payment projection data derived from a huge procedure that
I'm dumping into a temp table that looks like looks this:
I'm having a problem wrapping my head around how to get the rows in the
middle of each period.
The other, probably minor and statistically insignificant, issue is
proration on a leap year. If a proration occurs on a leap year and I
have to calculate the proration based on a DATEDIFF and an Annual or
Monthly Amount, I'm going to be a day over.
I’ve just remembered a very small yet challenging SQL statement brain teaser a friend of mine asked me long ago.
Though as simple as it might seem, I still couldn’t figure out how to solve it until this day. I just thought that some of you guys might have an answer to it.
Here is the question:
You have a table named “table1� that has only 2 fields: “name� and “phone�.
This table is populated with the following sample data
NamePhone --------------------- John111111 Tom222222 Jack333333 John444444 Smith555555 ---------------------- 5 records
To get all the distinct names in this table, you would write the sql statement: Select distinct name from table1
And the result would be:
Name ------- John Tom Jack Smith ------- 4 records
The question is: can you write a sql statement that can return all the distinct names along with their phone numbers.
E.g.
NamePhone --------------------- John111111 Tom222222 Jack333333 Smith555555 ---------------------- 4 Records
This one has been stumping me for several days. I can run a query thatreturns several different items from several different manufacturers,each with a ranking score. Each manufacturer can have any number ofitems:Item_Name Manufacturer rankItem 1 Manu_A 82Item 2 Manu_A 65Item 3 Manu_A 41Item 4 Manu_B 32Item 5 Manu_C 21Item 6 Manu_B 19However, I would like the records to be ordered so that the highestranking item is shown first, then the next highest item from adifferent manufacturer is shown second, then the next highest item froma third manufacturer is show, etc.:Item 1 Manu_A 82Item 4 Manu_B 32Item 5 Manu_C 21Item 2 Manu_A 65Item 6 Manu_B 19Item 3 Manu_A 41Does anyone have any thoughts on how to order the results in thisfashion?thanks,Matt Weiner
I need to produce a result that has 1 column that is the concatenation of each COORD separated by a '.' by increasing LEVEL
EX: The result should look like this 1.1.1 1.2.1 1.2.2 1.2.3 1.2.4 1.2.5 1.3.1 1.3.2 1.3.3 1.3.4 1.3.5
Please note that the answer must be flexible enough to handle any number of levels and coordinates (although levels will most likely be less than 5 and coordinates less than 100)
I am trying to create a query that will show how much revenue that we have recieved from a customer After the first invoice and I'm having a difficult time creating a query to do it.. I have a customer table and a sales table joined by custno. SELECT Customer.LastName, Sales.InvDate, Sales.AmtChargeFROM Customer INNER JOIN Sales ON Customer.CustNo = Sales.CustNo The output I'd like is CustNo, LastName, FirstInvoiceAmount, LifeCycleAmount Getting the first inv date seems straight forward SELECT Customer.CustNo, MIN(Sales.InvDate) AS FirstInv FROM Customer INNER JOIN Sales ON Customer.CustNo = Sales.CustNo GROUP BY Customer.CustNo However getting the amount of that first inv and then getting the sum of all invoices not including the first invoice has me scratching my head. Can anyone point me in the right direction?
Is there any way that I could achieve displaying the revenue grouped by a month?
I've got the following fields in order table: DateClosed, StartDate, EndDate, OrderValue
The fiscal year starts in march and ends in feb. I know how to calculate the year's revenue but I have got difficulties in spreading it over the months.
I'm trying to find out less than 10% in revenue accounts from a table. Below is a snapshot. Basically, I want to add Revenue mix column in the table using procedure.
I feel like I am having a total brain fart. I am trying to use a select * where statement to get all the records from my database that match a given setup and using a URL variable: Code:
SELECT * FROM dbo.TerraLogMain WHERE Volume = '#URL.VolumeID#'
Now I know for a fact that there are multiple records for Volume = Maps6 (for example) but I am only getting one record returned.
It also looks like the URL variable is getting passed okay: Code:
I am trying to calculate how much revenue we may get, based on potential new business opportunities. The core fields we have are
Total Contract Value ($ or £)Duration of contract (months)Revenue start dateVarious information about the new business - ID, Title, Customer etc.
We can easily calculate the revenue per month with "Total Contract value divide by duration".
However what I would really like to do is be able to know how much revenue we will be getting each month.
To do this I was thinking we should probably create a new row for each month entry, with the mm-yyyy being the only difference for each row. But how to create the appropriate months and the correct amount of rows.
Should I just pass an array of column names and use the AddWithValues SqlCommand method while looping through the array? Any comments are greatly welcomed.
Hello,I am working on a Blog and a Documents systems.What I need is:1. Each blog can have various language versions.2. Each document can have various language versions.I have been thinking about this and I end up with two approaches:1. Use a structure where all tables depend on a localized table:BLOGS|---- BlogsLocalized|---- BlogsPosts|---- BlogsRatings|---- BlogsComments2. Use a structure where each table has a localized versionBLOGS|---- BlogsLocalized|---- BlogsPosts|---- BlogsPostsLocalized|---- BlogsComments|---- BlogsCommentsLocalized3. Create a simpler, without localization, in SQL and in my web sites have different versions for each language.The same approach is under thinking for DocumentsTables.Could someone give me some advice?I have been looking in internet but until no I couldn't find anything really useful.Thanks,Miguel
Any help is sincerely appreciated:I have data in a table that represents the following:Admin Visit Type Registration Date Discharge Date D 20050301 20050301D 20050301 20050301W 20050301 20050301E 20050301 20050301D 20050301 20050302W 20050301 20050303W 20050301 20050311D 20050301 20050301Patient Type is always and I for the records I want but there are also Patient Types = O which I don't care about..What I would like to do is accoumlate a counter on the number of Registrations per date as well as Discharges per date.There can be thousands of registrations per day as well as thousands of discharges per day. So lets say I want to pass a date parameter to accumulate the total registrations and discharges per day. I have beat my head against the desk for the last two days because I believe this is a simple query but I just cannot get the results I want - so any help is greatly appreciated. I have written the following sql but I do not get a sum of the total registrations and discharges and EXPR3 and Expr4 always equal each other which is not the case . For example on 20040301 I have 88 registrations and 17 discharges but I can't ever get the correct totals...I wrote the following in Query Analyzer - but it does not work and I have went around in circles and have tried so many things I am just frustrated.........Declare @Parm_Beg_Date as nvarchar(8)Set @Parm_Beg_Date = 20040313 SELECT Patient_Visit_Result_Master.PVR_Admin_Visit_Type,Patient_Visit_Result_Master.PVR_Patient_Type, Patient_Visit_Result_Master.PVR_Registration_Date,Patient_Visit_Result_Master.PVR_Discharge_Date, Count(Distinct(Patient_Visit_Result_Master.PVR_Registration_Date)) as Expr3,Count(Distinct(Patient_Visit_Result_Master.PVR_Discharge_Date)) as Expr4 FROM Patient_Visit_Result_Master INNER JOINPatient_Visit_Result_Master Patient_Visit_Result_Master_1 ON Patient_Visit_Result_Master.PVR_Hospital_ID = Patient_Visit_Result_Master_1.PVR_Hospital_ID AND @Parm_Beg_Date = Cast(Patient_Visit_Result_Master_1.PVR_Registration_Date as nvarchar(8))or@Parm_Beg_Date = Cast(Patient_Visit_Result_Master_1.PVR_Discharge_Date as nvarchar(8)) WHERE (Patient_Visit_Result_Master.PVR_Admin_Visit_Type = 'E') AND (Patient_Visit_Result_Master.PVR_Patient_Type = 'I') AND (Cast(Patient_Visit_Result_Master.PVR_Registration_Date as nvarchar(8)) = @Parm_Beg_Date) OR (Patient_Visit_Result_Master.PVR_Admin_Visit_Type = 'D') AND (Patient_Visit_Result_Master.PVR_Patient_Type = 'I') AND (Cast(Patient_Visit_Result_Master.PVR_Registration_Date as nvarchar(8)) = @Parm_Beg_Date) Or (Patient_Visit_Result_Master.PVR_Admin_Visit_Type = 'W') AND (Patient_Visit_Result_Master.PVR_Patient_Type = 'I') and (Cast(Patient_Visit_Result_Master.PVR_Discharge_Date as nvarchar(8)) = @Parm_Beg_Date) Or (Patient_Visit_Result_Master.PVR_Admin_Visit_Type = 'D') AND (Patient_Visit_Result_Master.PVR_Patient_Type = 'I') and (Cast(Patient_Visit_Result_Master.PVR_Discharge_Date as nvarchar(8)) = @Parm_Beg_Date) GROUP BY Patient_Visit_Result_Master.PVR_Admin_Visit_Type,Patient_Visit_Result_Master.PVR_Patient_Type, Patient_Visit_Result_Master.PVR_Registration_Date,Patient_Visit_Result_Master.PVR_Discharge_Date Order By Patient_Visit_Result_Master.PVR_Admin_Visit_TypeThanks in advance
The principal and the mirror server are both running SQL Server 2005 64-bit Enterprise Edition. Witness is running Workgroup Edition. We are running in high availability mode (SAFETY ON).
3 nights before something strange happened and 1 database failed over (out of the six being mirrored) for some unknown reason. The other 5 didn't. We failed that one back and all seemed ok over the weekend. We came in Monday and found that the main live OLTP database was showing as the Principal on BOTH servers (in SMO/Management Studio and also in sys.database_mirroring). This is the "split brain" scenario that the presence of the witness is supposed to prevent. Both databases were accessible with a USE statement - clearly not right.
I pondered what to do, eventually I decided to remove mirroring from this database. That was ok until suddenly a few minutes later we realised the (original) Principal was in recovery! uisers of course were kicked out/unable to connect. I tried to force recovery with RESTORE DATABASE dbname WITH RECOVERY but it complained users were connected!
I had to KILL the users then recovery proceeded and the database became available again. I forced the mirror offline to prevent accidental usage.
This is obviously a nasty situation where mirroriing - which is supposed to prevent downtime - actually caused it instead.
I intend to log a call with CSS but I wanted to warn other users if they encounter something similar - it has shaken my confidence in mirroring quite severely.
Ok... I know this is something that I've seen and probably done before....
I have a value that will show up multiple times in a table. I want to order the table by that value and then count up from 1 to however many items that it shows up as.
The example below shows the results I want. Value1 and Value2 are in the table, LineNumber is what I need to generate.
For anyone who can help me resolve this minor data issue. I am trying to clean a phone number column so that all numbers are reflected in the same way. I have phone numbers in my column in this this format:
(123)123-1234 123-123-1234 (123) 123-1234
How can I clean this column so that the numbers are reflected in this way: 1231231234
I'm having brain freez right now. Help me please!!! Thanks in Advance

ok can someone tell me why i get two different answers for the same query. (looking for last day of month for a given date)
SELECT DATEADD(ms, - 3, DATEADD(mm, DATEDIFF(m, 0, CAST('12/20/2006' AS datetime)) + 1, 0)) AS Expr1 FROM testsupplierSCNCR I am getting the result of 01/01/2007
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).

I'm trying to find the command to open up an odbc conection inside sql2005 express. I only have ues of an odbc connector, we're conection to remedy. We will eventually be using stored procedures to extract the data we need from remedy and doing additional data crunching. I'm a foxpro programmer so once I get the correct syntax for making the odbc connector I shold be ok. Also I need a really good advanced book on sql2005. The type of book that would have my odbc answer. I've spent all morning trying to find this information and was unable to.
Thanks in advance

We have a issue with a MDS server that have been over us for a couple of days, the original error msg from SQL Server Engine is the one "The query processor could not produce a query plan" but the ones we get on the Excel-Addin are "Sequece contains no elements" or "The value cannot be null" T
• Using Microsoft SQL Server 2012 (SP1) - 11.0.3393.0 (X64) for 6months on this server without issues
• Two weeks ago we started to have 2 errors: "Sequence Contains No Elements" | "The Value Cannot Be Null"
• We are using the last version of Excel Add-in

how do I get the variables in the cursor, set statement, to NOT update the temp table with the value of the variable ? I want it to pull a date, not the column name stored in the variable...
create table #temptable (columname varchar(150), columnheader varchar(150), earliestdate varchar(120), mostrecentdate varchar(120)) insert into #temptable SELECT ColumnName, headername, '', '' FROM eddsdbo.[ArtifactViewField] WHERE ItemListType = 'DateTime' AND ArtifactTypeID = 10 --column name declare @cname varchar(30)
-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!! -- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"
set nocount on go if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1 if object_id('tempdb.dbo
[code]....
This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?
For each customer, I want to add all of their telephone numbers to a different column. That is, multiple columns (depending on the number of telephone numbers) for each customer/row. How can I achieve that?
I want my output to be
CUSTOMER ID, FIRST NAME, LAST NAME, TEL1, TEL2, TEL3, ... etc
Each 'Tel' will relate to a one or more records in the PHONES table that is linked back to the customer.
do i need to nest a query in RS if i want a calculated column to be compared against a multi value variable? It looks like coding WHERE calcd name in (@variable) violates SQL syntax. My select looked like
SELECT ... ,CASE enddate WHEN null then 1 else 0 END calcd name FROM... WHERE ... and calcd name in (@variable)
When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?
