Expression Divide By 0 - How To Return N/A For Fields
Jun 3, 2015I am new to SQL. I added a calculated field to my dataset with and expression to calculate efficiency.
My expression is as follows: =Fields!EstTotLbrHrs.Value/Fields!ActTotLbrHrs.Value
In some cases my value for ActTotLbrHrs is 0, so it returns #Error
How do I return "N/A" for fields with ActTotLbrHrs = 0
Merging Queries To Return Different Fields In Same
Oct 25, 2005hi all,
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:
select count(*) as import_lic_no from appln_clip ac,consign_animal c,pet p
where ac.ac_id=c.ac_id and p.pet_no=ac.clip_id and ac.appln_id like 'A8%'
2. number of imported animal type that are licensed:
select count(*) as lic_imp_ani_type from pet p,clip c where p.pet_no=c.clip_id
3.percentage: 2/1*100
select percentage=
((select count(*) as lic_imp_ani_type from pet p,clip c where p.pet_no=c.clip_id)
(select count(*) as lic_imp_ani_type from pet p,clip c where p.pet_no=c.clip_id))*100
4.local animal type:total pet records - 1
select number=
(select count(*) from pet p) - (select count(*) from appln_clip ac,consign_animal c where ac.ac_id=c.ac_id)
5.local animal type that are licenced:total pet records-2
select number1=
(select count(*) from pet p) - (select count(*) from pet p,clip c where p.pet_no=c.clip_id)
6.percentage: 5/4*100
select percentage=((select count(*) from pet p) - (select count(*) from pet p,clip c where p.pet_no=c.clip_id)/
(select count(*) from pet p) - (select count(*) from appln_clip ac,consign_animal c where ac.ac_id=c.ac_id))*100

Return Non-matching Records On Two Fields
Jan 18, 2008
Here is a very basic question that I have.
I have two tables, A and B. Both have a customernumber and a batchid. This combination is unique in both tables.
How can I pull back the records from table A that do not have a corresponding combination in B?
I know I could find the ones that do match and then exclude them using an inner join and subquery, but is there a simpler way?
THANKS!
Trying To Return Whole Records With Distinct Fields
Oct 17, 2006Hi
I am trying to write a query that will return a full record with a particular distinct field (the rest of the record being the first such record that includes the distinct field).
For example, for the following:
Fruit Like? Colour
Apple Y Green
Orange N Orange
Banana Y Yellow
Grape Y Green
Grapefruit N Yellow
I would want to return (assuming Colour was the distinct field):
Fruit Like? Colour
Apple Y Green
Orange N Orange
Banana Y Yellow
How do I do this? I've tried using a join (of all different kinds) with a subquery that uses SELECT DISTINCT but this doesn't seem to work. I've tried GROUP BY but none of the aggregate functions seem to just take the first found field.
Thanks for any help you can offer.
SELECT - Dynamically Determine Fields To Return
Dec 6, 2004Hello,
I m writing a stored procedure to query a table Population that has the following fields - CityId, CityName, Plus0, Plus10, Plus20, Plus30, Plus40, Plus50, Plus60, Plus70, Plus80. The field Plus0 contains the number of people of age > 0 living in the city, Plus10 contains the number of people of age > 10 living in the city and so on. Given the city id and age groups like 20To40, 50To60, 40Plus, etc., I should be able to query the number of people in the city corresponding to the requested age group. Note that if the requested age group was 20To60, I need to make use of only 2 fields Plus20 and Plus60 in the table to compute this value. And if the requested age group was 40Plus, then I need only the value in the field Plus40. The problem is that a wide variety of age groups can be requested like 0Plus, 10Plus, ... , 80Plus, 0To10, 0To20, 0To30, .... 70To80.
Which is the most effecient way to handle this ?
1. Have a stored procedure that returns all the fields even though only 1 or 2 of them would be actually used ?
In this case, if I returned data for a large number of cities then there would be a lot of unnecessary information that was returned by the query. Lots of data would be passed through the network though most of it would not be used.
2. Have a stored procedure that takes in parameters @Plus0, @Plus10, @Plus20, .. @Plus80 that are bits indicating whether the field was required or not and then using a CASE statement to return values for a field only if the corresponding bit parameter was set, and returning NULL if the corresponding bit paramter was not set ?
In this case, I would be returning NULL for all those fields that were not required for a particular age group. This would save some network bandwidth, wouldn't it ?
3. Pass in the age group itself (ex: 0To20) as a parameter to the stored procedure and have lots of IF statements, one for each age group, that return only the fields that are needed for that age group.
This leads to a lot of code repitition.
4. Use a similar approach as above but use dynamic SQL queries to avoid code repitition.
But using dynamic SQL queries can affect the performance of the stored procedure as they need to be compiled each time.
5. Any other possible approaches ??
Looking forward to your responses,
Thanks much,
bmgun.
Need A Query To Return Rows Containing ALL Matching Fields
Sep 9, 2004I have three tables X,Y,Z. Table 'Y' is having foreign key constraints on tables 'X' and 'Z' (which happen to be primary key tables).
I would like to run a query in which I can retrieve rows from Table 'X' only if the matching rows in Table 'Y' have "ALL" their matching rows available in a simple query being run on Table "Z".
The "All" part is very important.
For more clarification, let me give you an example. Table "X" is equivalent to a mathematical "Equation" table which consists of an equation made up of several "Fields". These fields are stored in Table "Z". Table "Y" contains the primary keys from Tables "X" and "Z". i.e. Table "Y" determines what fields are required for an equation to be complete.
I am having a query "Q" on Table "Z" (Fields table) which returns me a bunch of Fields. Now, on the basis of these fields, I want to retrieve only those Equations (Table "X") which have "ALL" their required Fields present in the bunch retrieved by the Query "Q".
I hope I am clear enough.
Does anyone have any solutions???
Select Distinct One Some Fields, But Return All Feilds
Jul 23, 2005I was curious...Is there a way to select distinct on a combination of some fields andthe for each record returned also get the other fields of anarbitrarily chosen record matching the fields in the distinct record.For example, if I have a select distinct on say three fields:SELECT DISTINCT Code1, Code2, Code3but the table also has other fields, maybe Foo1 and Foo2, and I wantFoo1 and Foo2 to also be displayed. Since there may be multiplerecords that match a particular Code1, Code2, Code3, then I just wantone of those to be arbitrarily chosen.

Return Number Of Days By Year From Date Fields
Dec 3, 2013I need to associate aggregate gross_revenue with calendar year, but do not have a date field that reflects payment dates, just contract periods a start_date and an end_date. The contract periods are typically 1 or 2 years and can start at any time I.e start_date 6/1/2012, end date 5/31/13. I think by finding the number of days that fall in each calendar year and storing in a temp table, I can create a simple formula to associate revenue to each year.

Best Way To Return Data From SQL Database, Without Giving Access To Database
May 8, 2008Hello,
I have a quick question regarding getting data from a SQL database but I am slightly confused as to the best way to handle it.
Basically on of the projects I am working on I need to send data to another company, there are several calls required to the database to bring back various options for changing the questions asked on the front end.
Up to now all that has happened is there has been a mutual agreement between myself and this other company and they have just had access to the database to call a series of stored procs which I have written for them to access the data. Recently however the situation has changed and my client wants me stop them accessing the database however they still need to recieve the information from the database they recieve now.
What will be the best way to handle this? My knowledge of SQL is farily limited presently and I am only ust getting into learning a lot more about it.
Any help and advice would be greatly appreciated.
Kind regards,
Lee
How Can I Return A Database From The DataBase Explorer Of VB 2005 Express To The Object Explorer Of SQL Server Management Studio
Mar 3, 2008Hi all,
I just realized recently that a database "XYZ" in the Object Explorer of my SQL Server Management Studio Express (SSMSE) is put in the Database Explorer of my VB 2005 Express for processing a Stored Procedure in executing the SELECT statements (not by using Input and/or Output Parameters) during the ADO.NET 2.0-VB 2005 Express programming, then the content of the database "XYZ" is not in the SSMSE. How can I return the database "XYZ" from the DataBase Explorer of VB 2005 Express back to the Object Explorer of SQL Server Management Studio Express (SSMSE) safely? Please help and advise.

Default Values For Database Fields Yes Or No????
Aug 4, 2006Building the database I have come across different databases some that add a default value for every field and some that don't. I feel it is a hassle to add a default value, keep track if it is added.
I guess with a default value there would be no "NULL" values in the database but one could also make sure in the C# code that all the fields have a value when inputed and on the way out check for nulls.
What is the right way????

Database Tables And NULL Fields
Nov 17, 2006Hi 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??
DataTable And Autoincremental Database Fields
Sep 16, 2007Hi,
I got a problem regarding autoincremental Database Fields and DataTables. Using the technique to map the DataBase to an *.xsd file and trying to insert a Row into the table always results in this kind of error:Cannot insert explicit value for identity column in table 'Cars' when IDENTITY_INSERT is set to OFF.
This only happens when I set CarIDs properties AutoIncrement = true, AutoIncrementSeed = -1, AutoIncrementStep = -1. Having AutoIncrement = false, results in this error:Column 'CarID' does not allow nulls.
Do I missunderstand something, or do I need to change some parts? I would be glad if someone could help me and figure out what I am doing wrong.Thanks a lot have a nice weekend.Regards Johannes
Database Design - Boolean Fields
Nov 12, 2007I am designing a table where the object(s) that the table represents could have hundreds of boolean attributes. Which method of design would you chose for this scenario:Keep the booleans in the original object's table, potential for hundreds of nulls in a rowCreate a 2 more tables, one that has the boolean value names & ID. Another that relates an object (in original table) to a boolean value name/ID. No nulls, lots of joiningSo second method would probably normalize it, but I would suffer a performance cost, whereas the 1st method would be the easiest/quickest for joins but tons of null records. ThanksBen

View 1 Replies View RelatedBest Practice For Add, Edit Records Into Database With Lots Of Fields ?
Feb 7, 2006What's the best practice for adding / editing a record into a database with lots of fields ?I am not talking about the mechanics of it, as there are a lot of trivial examples using ADO.NET, stored procs, etc.
Deleting is easy, you just pass in (a few) primary key/keys to uniquely identify the record.
But in the real world when you have, say, a table with 100 fields! Do you code the INSERT sproc by hand, with 100 parameters... then call it with your ADO.NET code ? sounds like a lot of work to me...
What about updating! That's even worst, sometimes you may need to update only 3 or 4 fields, but using sprocs you would have to pass the whole 100 parameters in again, and "update" the whole record (when in fact you are only changing 3 or 4 fields).
With the update i could write different sprocs targeting only the fields i wish to update, but that sounds like duplicating work, vs having one generic update proc.
Sometimes i just feel like bypassing sprocs and having inline sql as it would be less work... but i know it is untidy.. and more potential to be buggy.
So come on guys (and gals)... let's hear your thoughts on how you would handle the insert / update scenarios when you have lots of fields ? Northwind examples are too trivial :-)

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.
