How Do Make Sure If Column Is Null Before I Count It? ( Use SQL 2000)
Apr 29, 2008
the Table columns is like this
NO ProductNo Area In Out
1 0001 US NULL NULL
2 0002 UK NULL Y
3 0003 FR Y NULL
4 0004 FR Y NULL
5 0005 UK Y NULL
I have Query get the result below
Area Count In&Out
US 1
UK 2
FR 2
the Area is Group By by Area
and the Count columns is counting how many recoreds Table for each Area
the 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 below
Area Count In&Out
US 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
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.
I use SQL 2000 I have a Column named Bool , the value in this Column is 0�0�1�1�1 I no I can use Count() to count this column ,the result would be "5" but what I need is "2" and "3" and then I will show "2" and "3" in my DataGrid as the True is 2 and False is 3 the Query will have some limited by a Where Query.. but first i need to know .. how to have 2 result count could it be done by Count()? please help. thank you very much
In the below scenario we are inserting some time related fields in Temp table.But its data type is varchar. Once data loading is finished in the temp table (Data is loading by source team SQOOP and they are unable to load if the source datatype is having Date or datetime) we have to alter the column datatypes. somehow, some character data in inserted in date columns (look at into 3rd insert statement). while altering the table it is failing. Can we do any alternative for this (Means if any varchar data that is non convertible to date can we make as null)
INSERT INTO ##TEMP_TEST SELECT '2014-09-30','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' UNION SELECT '2014-09-29','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' UNION SELECT '2014-09-28','2017-10-06','Nov  6 2014  6:11AM','Nov  6 2014  6:11AM' GO INSERT INTO ##TEMP_TEST SELECT NULL,NULL,NULL,NULLÂ
Hi(SQL Server 2000)I have an existing table (t) with a column that is NOT an identity column(t.ID), but it has manually inserted "row numbers". I want to make thiscolumn become an identity column. This column is a key field to othertables, so I want to keep the row numbers that are allready inserted.From the Query Analyzer, how do I do this?Thanks in advance!Regards,Gunnar VøyenliEDB-konsulent asNORWAY
I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

I've tried variations on a SELECT statement like below but have been unable to find a way to count only those types per fileNo that have all partNo completed (and to count all types per fileNo with a partNo of 0 and a completed date as they have no parts):
SELECT [FileNo], COUNT(DISTINCT [Type]) AS CountOfAPs FROM APs WHERE (completed IS NOT NULL) GROUP BY [File]

I joined different tables and got a result like this:
result | process | goal | date | ------- ---------- ------ ----------- ok | process4 | 1 | 12.10.2013 bad | process1 | 2 | 13.10.2013 ok | process1 | 4 | 12.12.2013 good | process4 | 1 | 03.01.2014 ok | process1 | 3 | 10.04.2013 bad | process3 | 6 | 09.01.2014 bad | process4 | 3 | 30.12.2013 best |NULL| NULL
Now I want to count the results by counting the processes and group them by the result.
But it should be count the latest result per process only, e.g. for goal "1" just "good" at 03.01.2014. I solved that with a subquery (date=SELECT MAX(...)..).
But now the result "best" disappears, because that column has no date.
Secondly I want to count results for a specific process, e.g. for process4. Every goal has max. one process, with different dates. But one process could have more than one goal.
I want to have this result for process4:
count | result ------ ------- 1 | good 1 | bad 0 | ok 0 | best
But I got only:
count | result ------ ------- 1 | good 1 | bad
I have tried a lot, but nothing works.
The whole result (best, good, ok, bad) are stored in an other table and I joined it.
Total amount = 1000 salemancode1 = space salemancode2 = Staff-99 salemancode3 = space salemancode4 = staff-88
How I can write a one query statement to do this, we expect to count how many salemancode is not space and count the number of salesman to over the total amount.
total amount / (no_of_saleman) as commission the result is 1000/ 2 the commission is $500.
I have a DB of professors and information related with them. I created the cube, it consist of: Measures: Measure group Professors: Amount of projects (COUNT proj_id) Amount of pulications (COUNT pub_id) Amount of e_books (COUNT book_id) -------------- Measure group Projects: Distinct amount of projects (DISTINCT COUNT proj_id) -------------- Measure group Publications: Distinct amount of publications (DISTINCT COUNT pub_id) -------------- Measure group E_books: Distinct amount of e_books (DISTINCT COUNT book_id) -------------- Calculated measures: Amnt_Projects iif ([Measures].[ Amount of projects ] = 0 OR [Measures].[ Amount of projects] = NULL,0,[Measures].[ Distinct amount of projects]) Amnt_Publications (similar to the above one) Amnt_E_books (similar to the above one) --------------------------- Dimensions: dimPROFESSORS - prof_id -surname -name -gender dimPROJECTS - proj_id -type name -name dimPUBLICATIONS - pub_id -type name -name dimE_BOOKS - book_id -name Date_Projects -date_id -years Date_Publications -date_id -years Date_E_books -date_id -years
For example, when I browse the cube: prof_id____Amount of projects___Distinct amount of projects___Amnt_Projects 1032------------------- 30 --------------------------1----------------1 1070-------------------90 --------------------------2----------------2 1111-------------------0 ---------------------------1----------------0 1137-------------------0 ---------------------------1----------------0 1234-------------------1404--------------------------9----------------9 1721-------------------504--------------------------7----------------7 2661-------------------85 --------------------------5----------------5 ...--------------------...---------------------------...----------------... 6999------------------- 20---------------------------1-----------------1 9956-------------------50---------------------------5-----------------5 Unknown----------------(empty)---------------------(empty)-----------0 Grand Total------------ 2421------------------------11-----------------11
Grand Total “11“ is the amount of distinct projects +1 (because of the unknown member). So the last column shows the right amount of projects for the professor but I want Grand Total to sum those values and show, how many projects do the professors have (it should be „59“ if for all professors). How could I get the right value to be shown in Grand Total?

We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change DECLARE@size varchar(5)--The new size of the column DECLARE @TSQL varchar(255)--Contains the code to be executed DECLARE @Object varchar(50)--Holds the name of the table DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10) ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1 Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'. Msg 1750, Level 16, State 0, Line 1 Could not create constraint. See previous errors.
None of the fields I try to create the key on are nullable.
I receive this message when I try to run any report. The reportserver and reportservertempdb databases were upgraded using backup/restore from SQL2000 to SQL2005 on a separate server which is running RS2005 . Please help. Thanks
I have a table that contains names that are all in upper case, this column is called in many different areas of my web app. I wanted to make the names all lowercase, or with the leading character only capitalized. How can I make a column within a SQL table lowercase at the SQL server end and not the programming side?
Is this the way to create one of my columns clustered. The books that I have all use stored procedure I only want to use regular sql commands. Is this possible?
I have a store procedure to create a table temp, populate data from Origin1 table, and then add a new column SSN to temp table, update the SSNs from another table. but the following code gives error, pleaes help!
Create table temp ( .... ) Insert into temp select * from Origin1
Alter table temp ADD Name int
Update temp Set SSN = (select SSN from Origin2 where id = Origin.id)
it gives 'Invalid column name: 'SSN' I am aware that the add new column doesn't take effect until end of the SP, but there must be a way, Thanks for any inputs.
