I am stuck at a problem, not sure on how to go about writing a query that will return as a percentage the number of fields in a row that are null.
For instance, a row from my table:
Row1 : field1 field2 field3
If field3 is empty or null, my query should return 67%.
So far I have gotten the number of fields:
select count(1) from information_schema.columns where table_name='myTable'
I could loop through the fields but I am sure there is a simpler way of doing it, I have seen something simpler in the past with some builtin SQL functions. I am using MS SQL 2005.
the Table columns is like this NO ProductNo Area In Out1 0001 US NULL NULL2 0002 UK NULL Y3 0003 FR Y NULL 4 0004 FR Y NULL5 0005 UK Y NULL I have Query get the result belowArea Count In&OutUS 1UK 2FR 2 the Area is Group By by Area and the Count columns is counting how many recoreds Table for each Areathe problem is the column "In & OUt'I have to make sure if the "In" or "Out" is Null , if one of them is Null the plus 1 so the result would like I have Query get the result belowArea Count In&OutUS 1 1 UK 2 1 FR 2 0 which syntax I can use for the problem? I just think maybe I can use IsNULL?but I have no idea how to wirte a query ...can you give me a hint? thank you
How do I write a query to give me the total records in databaseA.tableA divided by the total records in databaseB.tableA This is what I have so far:DECLARE @today as datetime DECLARE @past as datetime
/* set the dates */ set @today = getdate() set @past = getdate() - 3 /* Go back 3 days */
/* create temp table for holding total cases*/ CREATE TABLE #CaseTotalCount ( TotalCount int )
/**/ CREATE TABLE #FlashCycleCount ( FlashCount int )
/**/
INSERT INTO #CaseTotalCount (TotalCount) SELECT COUNT (DataBaseA.dbo.tblProcedureData.CaseID) as TotalCount FROM DataBaseA.dbo.tblProcedureData WHERE DataBaseA.dbo.tblProcedureData.Date < @today AND DataBaseA.dbo.tblProcedureData.Date > @past
/**/ INSERT INTO #FlashCycleCount (FlashCount) SELECT COUNT (DataBaseB.dbo.tblFlashLog.FlashLogID) AS FlashCount FROM DataBaseB.dbo.tblFlashLog WHERE DataBaseB.dbo.tblFlashLog.LoadDate < @today AND DataBaseB.dbo.tblFlashLog.LoadDate > @past
/*function call*/ SELECT dbo.percentage(#FlashCycleCount.FlashCount, #PeriOpTotalCount.TotalCount) FROM #FlashCycleCount JOIN #PeriopTotalCount ON #PeriOpTotalCount.TotalCount != 0 This works but when I try to bind this to a formview a get nothing. any ides?
I have a program which brings in Skill ratings for an assesmnet people with the title of "Worker have to take aolng with a file number they are assigned. The program also being in the reporting line that each worker is a part of.
The rating levels are 1 through 5. What I need to do is to do is create a table that shows the count and percentage of each rating giving to the workers for each skill grouped by Vp, AVP, Supervisor and Director. So all the works that are Ultimately under a AVP and all the wokers that are Ultimately under a director and so on.
NameRoleSkillCount of % of Count of % of Rating 1 Rating 1 Rating 2 Rating 2 Gerald VPA1100 29% 13033% Gerald VPB195 28% 9524% Gerald VPB2120 35% 7018% Gerald VPB330 9% 10025% KimVPA1 KimVPB1 KimVPB2AND SO ON
I have tableX with columns colA, colB, colC, colD and there are 2256 rows in the tableX.
I would like to find out the percentages of colA, colB, colC, colD that hold data (where it is not an empty string or NULL value).
So out of 2256 rows in the table, the user has stored data in colA 1987 times, colB 2250 times, colC 2256 times and colD 17 times.
So the report would say:
colA: 88.07% colB: 99.73% colC: 100% colD: 0.01%
We have an application that has a bunch of fields that we believe are not being used and would like to remove them, but we need to prove this by looking at the data.
I know I could run a query, one at a time and change the column name, but this would take a long time as there are a lot of columns in this table. I am hoping there is some way to do this in one query.
I have just started using SQL Server reporting services and am stuck with creating subreports.
I have a added a sub report to the main report. When I right click on the sub report, go to properties -> Parameters, and click on the dropdown for Parameter Value, I see all Sum and Count fields but not the data fields.
For example, In the dropdownlist for the Parameter value, I see Sum(Fields!TASK_ID.Value, "AppTest"), Count(Fields!TASK_NAME.Value, "CammpTest") but not Fields!TASK_NAME.Value, Fields!TASK_ID.Value which are the fields retrieved from the dataset assigned to the subreport.
When I manually change the parameter value to Fields!TASK_ID.Value, and try to preview the report, I get Error: Subreport could not be shown. I have no idea what the underlying issue is but am guessing that it's because the field - Fields!TASK_ID.Value is not in the dropdown but am trying to link the main report and sub report with this field.
Am I missing something here? Any help is appreciated.
I'm trying to get a calculation based on count(*) to format as a decimal value or percentage.
I keep getting 0s for the solution_rejected_percent column. How can I format this like 0.50 (for 50%)?
select mi.id, count(*) as cnt, count(*) + 1 as cntplusone, cast(count(*) / (count(*) + 1) as numeric(10,2)) as solution_rejected_percent from metric_instance mi INNER JOIN incident i on i.number = mi.id WHERE mi.definition = 'Solution Rejected' AND i.state = 'Closed' group by mi.id
I want to add a percent column to the RIGHT of the total, and also on the bottom row. I can't find any clear examples of how to do this. If I had a new column, it adds additional headers beneath my top row. Or, my columns appear to the LEFT of the data, not the right. Can some please post some simple instructions that will make my simple matrix look like this:
Name Jan Feb Total %
John 5 6 11 60%
Mary 3 4 7 40%
Total 8 10 18 100%
% 40% 60% 100% 100%
I am so stuck on this I can pull my hair out.
Thanks!
Michael
p.s. I really hope the next version of SSRS has a simple "Sub-total %" option that you can enable just like the sub-total column.
Hi, I would like to generate following table with reporting service matrix. But if I use the expression : percentage coulmn=sum(field!qty.value) / sum(field!qty.value, "region_group") It will become a percentage of a row total, instead of a group total (store group). Please see the second table. Any ideas?
I'm trying to work out the value of a item as a % of the group.Using my simplified table below (table called sweetie)
Date Name Sweets 01/11/2011Pete5 01/11/2011Paul10 01/11/2011Paddy15 02/11/2011Pete2 02/11/2011Paul4 02/11/2011Paddy6
I would like to select a column called PERC, which would be the sum of Sweets/sum of Sweets(grouped by date).So for example for the first value I would have 5/(5+10+15).I can write the query so it totals all the sweets, but I want to use totals by date and am unsure how I would do this..My query so far is (but this doesn't use totals by date)
Hi. I am looking to create a Matrix-based Report in SQL Server 2005 Reporting Services. I have my query, and a dynamic number of both rows and columns. I have Totals on the "bottom" and "right".
What I'd like to do is add a Percentage column to the right of the right-based Totals column. So the columns would read Col1, Col2, .., ColN, Total, Percentage.
How can I add a Total Column as the last column in this query and also add a total column to the bottom row of the query? Then after the total column on the right, add a % column. So my expected returned set would be like so:
We have a table to 100M rows and up until now we were fine with an non clustered index a varchar(4000) because we never went above 900 bytes (yes it is a bad design).We have the need to support international character sets now so the column was updated to nvarchar(4000) and now we have data past the 900 byte limit.
The data is long, seems useless but is needed by the business and they need to be able to search "where bigcolumn like 'test%'". With an index, even with a huge amount of data, it was 'fast'. Now of course without an index it is unusable. The wildcard is always at the end of the search. I made a full text index on the column and basic queries such as: select * from ourtable where contains(bigcolumn, 'AReallyLongStringofTextHere') works fine unless there is a space in the data. We loose thousands of returned rows because of spaces in the data.
I have tried select * from ourtable where contains(bigcolumn, '"AReallyLongStringofTextHere that includes spaces"') but not all of the data is returned. I get 112 rows with the contains statement. The table scanning statement of "select * from ourtable where bigcolumn like 'AReallyLongStringofTextHere that includes spaces%' returns 1939 rows.I understand that a full text index is breaking the long string up since it contains spaces. Is there a way to retain the entire string as 1 index entry or is there a way to fix my query to return all of the rows?
i have a report with contains preview of percentage columns example of percentage of student marks in perticular subject like 95%. and if suppose any student not attend any test i have to dispaly like not attended statement.
so i have display two fields like 95% and not attended statement in same column, i given Cstr(Fields!Data.Value), it gives two fields with contains not attended statement of perticular query and it dispalys 0.95 % . but i need 95% and not attended statement for perticular query in same column.
is there any solution for dispalying string and percentage values in single column for given perticular query and those two values are disply same result compare with preview at the time of export to excel sheet
I have a table named pop. This table has 2 fields, field codes with articles and other field with details of those articles. I intend to make a count to items that have more than 1 detail. In addition to this result is possible result for example:
Detailarticles 64 535 4111 3523 22207
the first line says I have 4 articles with 6 details.
which is correct but how do you SUM the COUNT field? In other words, I want the total number of duplicate records in the table. Is there another way alltogether?
I tried:
SELECT LoanNo, SUM(COUNT(LoanNo)) FROM DedupTest031504 GROUP BY LoanNo HAVING COUNT(LoanNo) > 1;
but I get a "CANNOT HAVE AGGREGATE FUNCTION IN 'SUM(COUNT(LoanNo))' error.
If I am totaling fields by groups of rows and I do so for every group do I need to use a stored procedure or cursor for this? I don't have a lot of experience with these areas but will give it a go based on what I find out.
I am trying to total the "error code" fields for each Branch. Of course, some don't have any, some have multiple errors. If a stored procedure is the only way, it will be a problem as our company's DBA has not given me permissions to run SPROCs. Is there a way to do this in a query?
I have been trying to figure out a subquery for this and it is not working.
Hi all,I'm running into a road block, and I know I've done this before. I'mgetting fields from two tables, and I need to do a count of similaritems with it showing some extra info.Here's my fields:Log.LogId - IntLog.LogDispatcherID - IntOfficer.OfficerID - IntOfficer.OfficerFirstName - VarcharOfficer.OfficerLastName - VarcharI can get the info I need without a count with this:select a.LogID,a.LogDispatcherID,b.OfficerFirstname + ' ' + b.OfficerLastname as OfficerNamefrom[Log] a, Officer bwhere a.LogAssigned1 = b.OfficerIDBut when I try to add a count and group-by it errors out:select Count(a.LogID) as LogCount,a.LogDispatcherID,b.OfficerFirstname + ' ' + b.OfficerLastname as OfficerNamefrom[Log] a, Officer bwhere a.LogAssigned1 = b.OfficerIDGroup By a.LogIDI've done this before, but this isn't working. It's giving the error"it is not contained in either an aggregate function or the GROUP BYclause" for each field other then LogID.How can I do this? I want output similar to this:LogCountLogDispatchIDOfficerName334Tom Jones422John Smith.... EtcThanks for any suggestions or ideas...Sam Alex
I am working on Sql Server 7.0 with a group of Visual Basic programmers that have made the following request:
1.They want all decimals/integer fields in the database to default to 0(zero). Is there an way to do this for all fields instead of on an individual basis? 2.They don't want a null returned on any character string field.
What is the best way to take care of these 2 requests? Thanks in advance. Karen Suenram
SELECT expense_id, CAST(expense_id AS char(10)) + ' - ' + CAST(trip_km AS char(5))+ ' - ' + CAST(expense_amount AS char(5)) + ' - ' + charge_centre AS ExpenseDesc
If charge center is null, I need to ignore this field. How can I achieve this? The reason is that if any of the field is null, it will return ExpenseDesc as null.
The thing about the region is that it can be defined by states only, in which case CountyID and CityId are NULL, can be defined by Counties too, in which case only CityID is NULL or it can be defined up to City level, in which case all 3 are set to something. Example, Northeast would be all cities from northeast, but Pocono would be just some counties in PA, and so on...
The issue is now selecting all cities that belong into a region... Normally I would join the Zips table with the Region_Data table and retrieve all CityIDs... The issue is that, as I said, the CountyID and CityID might be null for some records, so I am not sure how to retrieve them?
I came up with one idea in which I create 3 temporary tables and I select in them all the records that have 1) only state, 2) only state and county, 3) all 3, then I join each and I union the results...
But I am wondering if there is a way to do the select in one shot?
Im trying to use MS SQL server mananagement studio to greate a view to recive information from my database. The problem i have is that i include a tabel where a post have "Null" then that post will not be shown i my qustion/View.

Greatful for very fast, help. Need this to be solved tomorrow :-(
1) Cannot have results in which both m.homephone & d.homephone are both null, or both m.workphone & d.workphone are both null in the result set
2) We also do not want to see any combos where one homephone is null and the other has only the char 0....same for workphone...no null & 0 combinations.
e.g.
m.homephone d.homephone
null 0
0 null
The phone fields are varchar
I know this is hidiously wrong but is my first sloppy attempt at best: select m.number, m.homephone as master_homephone, d.homephone as debtor_homephone, m.workphone as master_workphone, d.workphone as debtor_workphone
FROM master m
INNER JOIN debtors d ON d.Number = m.number
where (d.homephone <> m.homephone OR d.workphone <> m.workphone) AND (d.homephone IS NOT NULL AND m.homephone IS NOT NULL) AND (d.workphone IS NOT NULL AND m.workphone IS NOT NULL) AND NOT ((d.homephone IS NULL AND m.homephone = '0') OR (d.homephone = '0' AND m.homephone IS NULL)) AND NOT ((d.workphone IS NULL AND m.workphone = '0') OR (d.workphone = '0' AND m.workphone IS NULL))

Hi there, I have a fairly generic question regarding database design. I am working on my first database using SQL Express. I am testing the database by inserting records into the pre defined tables. Sometimes I forget to input text into a non null field. When this happens it displays an error and then skips a few rows which makes my row numbering messy. For example say I have Row 1, Row 2 Row 3 all nicely formatted but on Row 4 I make a mistake this row then disapears and their is gap between 3 and 5 where 4 was. Although I am just testing, I was wondering what happens in a real scenario if an inexperienced data input person makes a few mistakes it makes the database numbering systems look bad. In this case is it common to make most fields NULL to allow for admin errors??
