How To Return Number Of Selected Rows From All Queries Performed On DB
Feb 20, 2013
Recently I had an application developer approach me and asked if I could provided him with a list of sprocs by returned row count. We had an issue where the application passed in a number of parameters which attempted to return 200k plus rows of data and the application was timing out. He changed the required parameters in the application and a reasonable number of rows were returned as expected. Short term solution to this one problem.
However there are always timeout issues with this particular application and we got to thinking that maybe other sprocs that were called using parameters would also fail at some point in time because too much data was being returned.
This is my SQL : Select p.patientid,p.patientname,p.patientIc,pvi.DateOfAdmission,pvi.visitid,pvi.ward,pvi.bedno,pf.status,pvi.SurgeonName,(f.Title + ' ( Ver ' + (CAST(f.Version as Char(10))) + ')') as Title FROM patient p, patientvarianceinfo pvi,patientForm pf,Form f where (p.PatientName LIKE '%" & Name & "%' or p.PatientIc LIKE '%" & ic & "%' or pvi.Ward LIKE '%" & ward & "%' or pvi.Bedno LIKE '%" & bed & "%') and (p.patientid = pvi.patientid) and (p.patientid = pf.patientid) and (pvi.patientid = pf.patientid) and (pf.FormID = f.FormID)and p.patientid in (select patientid from patientform pf)how do i get the number of rows?
hi,i have a stored procedure like this in SQL server ,it returns proper value if data is there for a given id.But if there is no data,it returns row/rows of NULL value and that is counted towards "number of row returned"..Shouldn't it be like,if there are null values in a row,that row should not be counted towards rows returned value .?Rightnow if no value returned from either of the select,it still returns as 2 rows instead of 0 rows.How do handle this situation in SQL? thanks for your help SELECT SUM(col1) AS SUM_COL1, SUM(col2) AS SUM_COL2, SUM(col3) AS SUM_COL3, SUM(col4) AS SUM_COL4FROM TABLE1WHERE (ID = nn) UNION all SELECT SUM(col22) AS SUM_COL22 ,cast(null as int) as c1,cast(null as int)as c2,cast(null as int) as c3FROM table2WHERE TABLE2 = nn)
I have a Dataset that I am populating from a SQL Query. I am then using the dataset to populate a report in Reporting Services. What I want to do is return a standard number of rows in my dataset. (Let's say 10.) Even if my query does not have any rows in it, I want 10 empty rows returned to the dataset. If my query has 7 rows in it then I want to add on 3 empty rows and return it. I will not have more than the standard number of rows. I cannot get the table in the report to show up if the dataset is empty, but still want the table to display with 10 empty rows. I have searched how to do this online but am getting nowhere. (I know how to add one empty row but not a set number.
Hello, Any help would be greatly appreciated. I have a single row that looks like this. Cust, Add, Item, Value 1 ST 258 6 I want to return six rows based on the value and the value could be any number. All of the row information will stay the same except the Value that will count off of the original value. Cust, Add, Item, Value 1 ST 258 1 1 ST 258 2 1 ST 258 3 1 ST 258 4 1 ST 258 5 1 ST 258 6
Can anyone just point me in the right direction. All I want to do is add some T-SQL to an existing stored procedure to return the number of rows selected into a return value.Does anyone know how to do this?
I have a policy table which has policyNumbers and createDate. I need to retrieve all rows where createDate is between 2 dates and there is more than 1 row with the same policy number. I cannot figure out the SQL to return all policy number rows if there are more than 1 row with the policy. Most policies number will be in the table once. I need the others.
i read from help files that "For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. " Anyone know how to get the return value from the query below?
Below is the normal way i did in vb.net, but how to check for the return value. Please help.

90% of Total cpu usage is showing for Adhoc Queries. what excatly this means in Dashboard? if application uses more than it would have shown in Database level or not?
sicerely this dashboard is good, if any one is watching daily, please advice their experiences here.

I have to dts rows by timestamp. For example if my dts downloaded at 10 am then in the next run i want to grab rows updated in the AS400 after 10am. what is the best way to go in ssis?
First, I have that code whenever i disregard the "having ranges<=3" it selects record but when I include it it returns error. The problem is I want to just select records with ranges less than 3 miles..how do I do that.. and I want to count the number of selected rows and store it on a column on the same table.
I have a report which has a multi-value parameter. Problem is, it can contain up to 100 options.Is there a way to limit the number of options that is passed to the SQL statement?. EG list has 100 options, user selects 10 but only the first 4 selected options are passed to the SQL statement. Many Thanks Delli
Say you have a table that contains 1000 rows, you create a simple select statement with a where clause that returns 100 or so of those rows. Easy enough.
Now, let's say that you wish to modify that select so that out of the 100 rows that match the where clause criteria, you only wish to return 10 rows randomly (i.e., you could run this query multiple times and get different results). How exactly would you go about doing this, efficiently?
I've thought about creating a stored procedure that will query the initial 100 rows into a temp table with an additional column (to number the rows from 1 to 100). Then setting up a loop (10 iterations) that will then generate a random number from 1 to 100 and select that row number into another temp table. At the end of the loop I'll have my table of randomly selected records. I am sure there is probably a better way to do this...
"select * from sample order by newid()" im getting a set of rows. On refreshing this query i need the same set of rows to validate.(provided sufficient data in the table).
Hi!I'm a new T-SQL developer and just hit a roadblock.I have a scenario that goes like this: I have 2 stored procedures,spInner and spOuter. spInner has a SELECT statement which wouldnormally be used by a class using MS Enterprise Library and that outputgoes into a DataSet. However, I need to get the output of the SELECTstatement to go into spOuter and that's what I can't seem to figureout.I know I may be asked to use functions that return tables in replies tothis post, but I can't do that as some parts of my application have anEXEC(string) for dynamic SQL, instead of spInner.Any help appreciated.Cheers,N.I.T.I.N.
I have an external process that polls message rows from a table. apon taking them, it also needs to mark them as taken. there is a status column in the table. marking messages as taken will change the value of status.
How can i perform both these operations in one command? Select the top x rows where their status is equal 1, then update the status of those same rows to a value of 5 for example.
I could iterate through the result of hte intial select and change the status 1 by 1 using a cursor, but this seems like a slow option.
This SQL statement, though carefully written to delete only selected rows, deletes the entire A_Shift_Times table:
DELETE FROM A_Shift_Times WHERE EXISTS ( SELECT 1 FROM Users WHERE (A_Shift_Times.time_in >= CONVERT(DATETIME, '2000-05-29 00:00:00', 102)) AND ((Users.User_Password LIKE N'mrr%') OR (Users.User_Password LIKE N'work%')))
I have to write a couple scripts that will update a couple columns in two separate tables and also insert a new row with the same data except for a few calculated or provided values ...... see specs below ...
1. tGradeHist Table Script One (Needs to be run first)
a. Read tGradeHist Table and Select rows with GradeEndDate = NULL and GradeStartDate = '1/1/2007 12:00:00 A.M.'
b. Calculate New Step Amount = StepAmount * Incr% (Round To Nearest Whole Dollar)
c. Create New Row for this table using information from row read above and insert new information where indicated :
GradeCode - Same
GradeLocationCode - Same
Step - Same
GradeStartDate - '7/1/2007 12:00:00 A.M.'
GradeEndDate - NULL
GradeCurrencyCode - Same
StepAmount - Result of b (above)
GradeFrequencyCode - Same
RangeMaximumAmount - Same
RangeMidAmount - Same
RangeMinimumAmount - Same
GradeCurrentFlag - 'True'
MarketMaximumAmount - Same
MarketMidAmount - Same
MarketMinimumAmount - Same
GradeGUID - Same
TSCOL - Same
d. Update Row read in a (above) with GradeEndDate = '6/30/2007 12:00:00 A.M.' and GradeCurrentFlag = 'False'
2. tPersonBasePayHist Table Script Two (Needs to be run second)
a. Read tPersonBasePayHist Table and Select rows with PersonBasePayEndDate = NULL
b. Calculate New PersonBasePayAmount = PersonBasePayAmount * Incr% (Round To Nearest Whole Dollar)
c. Create New Row for this table using information from row read above and insert new information where indicated :
PersonGUID - Same
PersonBasePayStartDate - '7/1/2007 12:00:00 A.M.'
PersonBasePayEndDate - NULL
PersonBasePayCurrencyCode - Same
PersonBasePayAmount - Result of b (above)
PersonBasePayFrequency - Same
PersonBasePayPayrollFrequencyCode - Same
BasePayReasonCode - 'SA'
ConductedBasePayReviewDate - Same
ScheduledBasePayReviewDate - Same
PayrollCode - Same
PersonBasePayCurrentFlag - 'True'
ApprovedByPersonGUID - Same
PersonBasePayGUID - Same
TSCol - Same
d. Update Row read in a (above) with PersonBasePayEndDate = '6/30/2007 12:00:00 A.M.' and PersonBasePayCurrentFlag = 'False'
I am using sql server 2005. I stuck out in a strange problem. I am using view in my stored procedure, when I run the stored procedure some of the rows get skipped out means if select query have to return 10 rows then it is returning 5 rows or any other but not all, also the records displyaing is randomly coming, some time it is displaying reords 12345 next time 5678, other time 2468.
But if I run seperately the querys written in SP then it returns all the rows. Please give me solution why it is happening like this.
There are indexes in the tables.
Once I shrink the database and rebuild the indexes, from then this problem is happening. I have rebuild the indexes several time, also updated the statistics but nothing improving.
The columns in my excel source contain data of different types with the column name being a string and the data in those columns being integers. Is there any way to only extract numeric data , in short I want column names to be omitted. Also the data is distributed unevenly , beggining at various rows in each column.
I need to randomly order the selected rows from my table. Is this better to do on the Application level or in a stored procedure using "orderby NewID()"?
Which is faster? There will be about 100 rows returned with 10 columns.
I am new to MDX and I have created a query listed below, this returns the correct information from the cube. However when I split the query into a CREATE SET and Query the data returned is wrong. I need to include the set creation in the cube but this returns the wrong information. I thought that information returned by these two queries would be indentical can anyone explain please.
Thanks David
SELECT ({[Time Calculations].&[Current Period],[Time Calculations].[Prior Year]}) on columns, Filter (([Store].[Store No].[Store No].Members), ([LFL Month Store].[Month Lf L Store].&[Month LfL Store]) <> 0) on rows from finance where( [LFL Calendar].[LFL Calendar Hierarchy].[Year].&[2008].&[Qtr 1 2008].&[P3:April 2008] , [Measures].[GL Amount])
MS SQL server 2000 behavies strange with big queries that involves relatively large number of tables: If I just enumerate columns I want to receive, the result set is empty. Adding * to the column list without making any change to where clause seems to solve the problem but I guess it's not the best practice. The most amazing is that this behavior is not stable, so I suppose there's something to deal with server itself, not the application. Has anybody suffered this problem and what solution was adopted? Thanks for any information you can provide.
can anybody help in combining all the mentioned queries into a single query so as to display all fields in a row.
1.number of imported imported animal type:
