IF Object_id('GoldenSecurity') IS NOT NULL DROP TABLE dbo.GoldenSecurity;
IF Object_id('GoldenSecurityRowVersion') IS NOT NULL DROP TABLE dbo.GoldenSecurityRowVersion;
In the Operating environment databases, may be made tables in the database on a temporary basis but they are still yet and they are not removed, how to identify tables that have been made on a temporary basis are not used (don’t have any read & write records)?
Here is My requirement, I'm not sure if this is possible. Creating table called master like col1, col2 col3, col4 , col5 ...Where Col1, col2 are updatable - this can be done easily
Col3, col4 are columns in another table but these can be just a read only ?? Is this possible ? this is possible with View but not friendly with share point CRUD...Col 5 is a computed column of col 2 and col5 ? if above step can be done then sure this can be done I guess.
I have a need to insert stored procedure output a table and in addition to that add a datetimestamp column.. For example, Below is the process to get sp_who output into Table_Test table. But I want to add one additional column in Table_test table with datetimestamp when the procedure was executed.
I am looking to create a script that will go through a table a pick out the necessary columns to create a unique record. Some of the tables that I am working with have 200 plus columns and I am not sure if I would have to list every column name in the script or if they could be dynamically referenced. I am working with a SQL server that has little next to no documentation and everytime I type to mere some tables, I get too many rows back.
I was running an operation to shrink file/emptyfile a data file, and then remove it.
It blocked and caused a huge mess, I suspect on the removal part. But I want to confirm that the emptyfile completed (and that the engine isn't going to try to put more data in there for when I schedule the removal part again a week or more from now).
How does the engine know not to put any more data in there, and how long does that situation last?
I have a excel sheet with some data and blank columns. I have a ssis package using to import data from excel to sql table. For blank excel columns it is importing as null instead i want to show them as '0'. If data comes in it should update the data.
We have a table with 500+ columns. The data is non-normalized, i.e. there are four groups of fields for for "people", followed by data that applies to all people in the row (a "household").For ad-hoc queries, and because I wanted to index columns within each person (person 1's age, person 2's age, etc.), I used UNION:
SELECT P1Firstname AS FirstName, P1LastName as LastName, P1birthday AS birthday, HouseholdIncome, HouseholdNumber of Children, <other "household" columns> UNION SELECT P2Firstname AS FirstName, P2LastName as LastName, P2birthday AS birthday, HouseholdIncome, HouseholdNumber of Children, <other "household" columns>
I could get at least the P1... P2... P3... columns with PIVOT, but then I believe I'd have to JOIN back to the row anyway for the "household" columns. Performance of UNION good, but another person here chose to use PIVOT instead.I can' find any articles on PIVOT vs. UNION for "de-flattening".
I have a table #vert where I have value column. This data needs to be updated into two channel columns in #hori table based on channel number in #vert table.
CREATE TABLE #Vert (FILTER VARCHAR(3), CHANNEL TINYINT, VALUE TINYINT) INSERT #Vert Values('ABC', 1, 22),('ABC', 2, 32),('BBC', 1, 12),('BBC', 2, 23),('CAB', 1, 33),('CAB', 2, 44) -- COMBINATION OF FILTER AND CHANNEL IS UNIQUE CREATE TABLE #Hori (FILTER VARCHAR(3), CHANNEL1 TINYINT, CHANNEL2 TINYINT) INSERT #Hori Values ('ABC', NULL, NULL),('BBC', NULL, NULL),('CAB', NULL, NULL) -- FILTER IS UNIQUE IN #HORI TABLE
One way to achieve this is to write two update statements. After update, the output you see is my desired output
UPDATE H SET CHANNEL1= VALUE FROM #Hori H JOIN #Vert V ON V.FILTER=H.FILTER WHERE V.CHANNEL=1 -- updates only channel1 UPDATE H SET CHANNEL2= VALUE FROM #Hori H JOIN #Vert V ON V.FILTER=H.FILTER WHERE V.CHANNEL=2 -- updates only channel2 SELECT * FROM #Hori -- this is desired output
my channels number grows in #vert table like 1,2,3,4...and so Channel3, Channel4....so on in #hori table. So I cannot keep writing too many update statements. One other way is to pivot #vert table and do single update into #hori table.
public Set DoSomthing(Set toBeProcessed, Set measuresToWorkWith)The set measurseToWorkWith is passed as {[Measures].[Measure1], [Measures].[Measure2] ...}
with the measures being real or query-scoped calculated members.
To get the value of the measure for each tuple in the set toBeProcessed, I create an Expression for each tuple (measure) in the set measuresToWorkWith then for each tuple in toBeProcessed call expression.Calculate(tuple) which returns a MDXValue.
My problem is that in order to make the code generic I need to get the real (.NET) data type of the MDXValue. The class only has explicit conversion methods ToInt16() etc which implies that the data type is known at design time.
However, if one of the measures is a query-scoped calculation then it could return a .NET double, int, bool or string.
If the measure is real then I can look up its metadata. However, it appears that if it is a formula (scoped member) then are all bets are off?
I'm using MS SQL Server 2008 and I'm trying to figure out if it is possible to identify what tables / columns contain specific records.
In the example below information generated for the end user, so the column headers (Customer ID, Customer, Address, Phone, Email, Account Balance, Currency) are not necessarily the field names from the relevant tables, they are simply more identifiable headers for the user.
Customer ID CustomerAddress Phone Email Account Balance Currency js0001 John Smith123 Nowhere Street555-123-456 jsmith@nowhere.com-100 USD jd2345 Jane Doe 61a Down the road087-963258 jdoe@downthe road.com-2108 GBP mx9999 Mr X Whoknowsville 147-852369 mrx@whoknows.com0 EUR
In reality the column headers may be called eg (CustID, CustName, CustAdr, CustPh, CustMail, CustACBal, Currency).
As I am not the generator of this report, I would like to know whether or not it is possible to identify the field names and / or what tables they exist in, if I were to used the report info to search for it. For example, could I perhaps find out the field name and table for "jd2345" or for "mrx@whoknows.com", because the Customer ID or Email may not be what the actual fields are called.
I'm not a DB admin and I don't have rights to do a stored procedure on the server. I'm guessing what I want is not so simple to do, but is it possible to do via a query?
Same SQL Server DB engine (2012), connected with two different clients (2008 and 2012). When I check objects for performance condition alert, 2008 client shows the objects name with leading "SQL Server".But 2012 client displays just the object name and NOT prefixed with "SQL Server".we have automated alerts creation, so it fails depends on the client version.
I am trying to write a query to calculate the running difference between data on different dates. Below is what my table of data looks like. Basically I want to calculate the difference between the total_completed for each state and date.
below is my code (I almost have what I need) I just can't figure out how show 0 as the completed_difference for the first Date for each state since there is no prior date to calculate against.
MRR_TOTALS_WEEK_OVER_WEEK AS ( SELECT T1.[Date] ,T1.States ,T2.Total_Completed ,ROW_NUMBER() OVER(PARTITION BY T1.States ORDER BY T1.States,T1.[Date]) AS ORDERING FROM TOTAL_CHARTS T1 LEFT JOIN TOTAL_COMPLETED T2 ON T1.[Date] = T2.[Date] AND T1.States = T2.States )
When overriding the PrimeOutput method in a custom component, you get as parameters the outputIDs and the output buffers (of type PipelineBuffer). using the outputIDs you can get IDTSOutput90 outputs.
Basically I need to get the SUM of the sum of three columns and all three columns have nulls. To make it more complicated, the result set must return the top 20 in order desc as well.
I keep facing different issues whether I try and use Coalesce, IsNull, Sum, count, anything. My query never returns anything but 0 or NULL regardless of if I am trying to build a CTE or just use a query.
So I'm using Col A to get the TOP 20 in order (which is fine) but also trying to add together the sums of Col A + Col B + Col C for each of the twenty rows...
select * from sys.dm_os_performance_counters returns the object names prefixed with "SQLServer:" (e.g. SQLServer:Databases)
It was expected as in other editions also. Issue is that when we try to crate "SQLServer Performance Condition alert", object names in "Object" list comes without the prefix "SQLServer:" (e.g. Databases). Please see the attached snapshots.
I need out put in single row for below 2 queries using joins
SELECT [total_physical_memory_kb] / 1024 AS [Total_Physical_Memory_In_MB], CPU_Count AS NumberofCPU FROM [master].[sys].[dm_os_sys_memory] CROSS JOIN sys.dm_os_sys_info
I am trying to update a table and then also use OUTPUT clause to capture some of the columns. The code that I am using is something like the one below
UPDATE s SET Exception_Ind = 1 OUTPUT s.Master_Id, s.TCK_NR INTO #temp2 FROM Master_Summary s INNER JOIN Exception d ON d.Id = LEFT(s.Id, 8) AND d.Barcode_Num = s.TCK_NR WHERE s.Exception_Ind IS NULL
The above code is throwing an error as follows:
Msg 4104, Level 16, State 1, Procedure Process_Step3, Line 113 The multi-part identifier "s.Master_Id" could not be bound. Msg 4104, Level 16, State 1, Procedure Process_Step3, Line 113 The multi-part identifier "s.TCK_NR" could not be bound.
WE have a query which pulls revenue by country and client for the last 3 years. Right now we have each year being reported in separate columns but we would like to have the revenues for each year for each client to appear on one row. Below is the current query we have setup.
SELECT p.country_code, p.local_client_code, wwc.local_client_name, case when pr.fiscal_year = 2015 then sum(pr.local_consulting_fees*er.rate) + sum(pr.local_product_fees * er.rate) + sum(pr.local_admin_fees * er.rate) + sum(pr.local_misc_fees * er.rate) else 0 end as '2015 Revenue',
