I'm having some issues with what seems to be a simple update statement but is giving me grief when one or both of the columns I'm comparing are null. My statement (simplified) is as follows:-
UPDATE
TAB_A
SET
TAB_A.TRADCODE = TAB_B.TRADCODE
FROM
TADS_STAGE.DBO.UNCLBRAMDEPT TAB_B
JOIN
TADS.DBO.UNCLBRAMDEPT TAB_A
ON
TAB_B.BRANCODE = TAB_A.BRANCODE
AND
TAB_B.MERDCODE = TAB_A.MERDCODE
AND
(
TAB_B.TRADCODE <> TAB_A.TRADCODE
)
If either of the TRADCODE fields (or both) are null then the comparison fails to return the row to update. I've tried setting the ANSI_NULLS setting to off, this has no effect, presumably because it will only work when comparing a column to a variable or evaluating if the column is null itself.
I've considered using ISNULL, but if one of the columns happens to contain the value that I specify as the replacement value then the comparison will result true and not include the row.
I have two tables with the same structure / different data. I run a query between the tables to find the different records for the out put. When the values of the records or NULL, I do not get the output.
Code:
SELECT dbo.Closest3StoresB_RBT.CustomerPost, dbo.Closest3StoresB_RBT.ClosestStore1, dbo.Closest3StoresB_RBT.ClosestStore2, dbo.Closest3StoresB_RBT.ClosestStore3 FROM dbo.Closest3StoresB_RBT INNER JOIN dbo.Closest3StoresB_OLD_RBT ON dbo.Closest3StoresB_OLD_RBT.CustomerPost = dbo.Closest3StoresB_RBT.CustomerPost
WHERE (dbo.Closest3StoresB_OLD_RBT.ClosestStore1 <> dbo.Closest3StoresB_RBT.ClosestStore1) OR (dbo.Closest3StoresB_OLD_RBT.ClosestStore2 <> dbo.Closest3StoresB_RBT.ClosestStore2) OR
Hi , I need to compare two date fields in two different tables.One of the field is varchar(8) and other is dateime.When there is a date in one field and NULL in other field , how do I compare these two vales?
I need to check Table1 by Table2 only on NOT NULL cells and if all of them in the row match do not return that row as the result. In this case it will be:
SELECT a.Server, a.Databases, a.Users, a.Names FROM Table1 EXCEPT SELECT ISNULL(b.Server,c.Server), ISNULL(b.Databases,c.Databases), ISNULL(b.Users,c.Users), ISNULL(b.Names,c.Names) FROM Table2 AS a, Table1 AS c
But for many rows (like 100 000) it takes ages to get results, any better way to work on this?
How to find out that there is a null value in a column rather than a valid integer, DateTime or bool value, for strings I use 'as' operator to cast the column value and it returns null when column value is null, but for value types using 'as' operator causes compile error and using simple casting causes runtime error, for example:
int count = (int)row["Count"];
and
int count = row["Count"] as int;
the first one throws an exception when Count is null and the second doesn't compile at all since 'as' applies to reference types, so what is the way other than exception handling to determine null value in a column?
parsename('$'+ Convert(varchar,Convert(money,Q.[Product Cost]-R.[Shared Cost]),1),2) as [Pre Cost], parsename('$'+ Convert(varchar,Convert(money,R.[New Product Cost]-R.[Shared Cost]),1),2) as [Post Cost]
Formula: [Post Cost] / [Pre Cost]
Expected:
If [Post Cost] is null then I would need to assign 1 and divide by [Pre Cost] and similarly if [Pre Cost] is null then I would need to assign 1 so that I can divide [Post Cost] / [Pre Cost]
I have a little problem here. I need to select data from multiple columns and multiple tables, some of those columns can have NULL value. I have tried few things, and havent find the right way so far. Problem that i am incountering is that when i run SELECT statment as it is right now, i dont get back results which match search parameters but have NULL value in one or more column in select statment. How can i fix this problem?
We are writing a C application that is using ODBC to insert recordsinto a database. We have a NOT NULL column that can legitimately havean empty value, i.e. we know the value and it is empty (i.e. a zerolength string).We are using SQLBindParameter() to bind a variable to theparameterized insert statement <<in the form: INSERT INTO table VALUES(?, ?, ?)>>. We are using SQLExecDirect() to process the SQL.We are running into the problem where ODBC is converts the empty (zerolength) string into a NULL value and this errors due to the fact thatthe column is defined as NOT NULL.We do not want to redefine the column as NULL, becasue myunderstanding of the correct usage of a NULL column is to indicatethat a value is unknown or meaningless... in our case we know thevalue (it is empty) and an empty value has meaning within ourapplication.I'm sure that this issue has been seen and address thousands(millions?) of times... any guidance would be appreciated.
I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?
I am trying to think my way through a solution which I believe others have probably come across... I am trying to implement a matching routine wherein I need to match an address against a high value and a low value (or, for that matter an input date vs. a start and end date) to return the desired row ... i.e. if I were to use a straight vb program I would just use the following lookup:
" WHERE zip_code = @zip_code AND addr_prim_lo <= @street_number AND addr_prim_hi >= @street_number " & _
" AND addr_prim_oe = @addr_prim_oe AND street_pre = @street_pre AND street_name = @street_name " & _
" AND street_suff = @street_suff AND street_post = @street_post " & _
" AND (expiry_date = '' OR expiry_date = '00000000' OR expiry_date > @expiry_date)" & _
" GROUP BY fire_ID, police_ID, fire_opt_in_out, police_opt_in_out"
My question, then, is how would you perform this type of query using a lookup / merge join or script? I have not found a way to implement a way to set the input columns? I can set the straight matches without a problem, i.e. lookup zip code = input zip code, but can't think of the correct way to set comparisons, i.e. lookup value 1 <= input value AND lookup value 2 >= input value
I am using a Excel Source to get the data from an excel file to sql server 2005 table. A couple columns are coming in a double precision float, but some values have characters in them, but those values are coming out as null, even though I changed the datatype from float to unicode string. Any inputs on resolving this will be much appreciated.
SELECT * FROM PABX INNER JOIN LOGIN ON (PABX.COD_CLIENTE = LOGIN.COD_CLIENTE) AND LEFT(LOGIN.TELEFONE1,3) = LEFT(PABX.NRTELEFONE,3) LEFT JOIN AUXILIAR ON (AUXILIAR.ORIGEM=LOGIN.LOCALIDADE) WHERE pabx.COD_cliente = 224 and SUBSTRING(PABX.NRTELEFONE,4,1) NOT IN ('9', '8', '7') AND LOGIN.UF = RIGHT(PABX.LOCALIDADE,2) AND LOGIN.LOCALIDADE <> PABX.LOCALIDADE AND PABX.CLASSIFICA IS NULL AND PABX.LOCALIDADE <> AUXILIAR.DESTINO AND (BLOQUEADO = 0 OR BLOQUEADO IS NULL)
But It has a problem because when AUXILIAR.DESTINO returns null (it means there is no registry) the condition AND PABX.LOCALIDADE <> AUXILIAR.DESTINO doesn't work, like 'SAO PAULO' is different from 'NULL' but for my query no it's not even equal, and this condition ommit the results....how can I solve it ?
PS: Both auxiliar.destino and pabx.localidade is varchar(255)
Hello! I have a field "End" in my database that is mapped as DateTime and allows nulls. Now I want to do a SQL-Select (in a SqlDataSource) like SELECT * FROM My_Table Where (([End] = @EndDate) OR ([End] = null)) @EndDate is a valid DateTime, but the second OR condition doesn't work. What is the best way to check if the [End]-field is empty or null? Thank you very much!
I have two spreadsheets in excell. There are 3000 numbers on one sheet, and there are 900 numbers on the other sheet. I want to know which numbers overlap and either somehow flag the overlaping numbers on both sheets or create a third sheet that just contains the numbers that exist in both. Is there some straightforward set of function comands in excel to do this?
I would like to compare some values in two columns which are in the same table. I want to check that there are no differences between the values if the ID is Test1 and Test2

There are two tables in my Database, tb1 and tb2 which both have the same attribute ID. I would like to ensure that there is nothing in ID in tb1 which is not listed in ID in tb2, can anyone help?
I have a table called WorkItem. It models a chunk of work done duringa working day.It has two columns that I'm interested in:Start (smalldatetime) - the TIME the work block is begunDuration (int) - the duration in minutes of the work block.In another table called OvertimeRates I have information about ratemultipliers and a column that tells me the TIME that the ratemultiplier kicks in.e.g.OTRateBegins (smalldatetime)In terms of calculating whether a particular work block starts afterthe OTRateBegins, I could (I presume) do something like:If CONVERT(smalldatetime, Start, 108) > CONVERT(smalldatetime,OTRateBegins, 108)However, would I be better off using DATEPART functions to get the hourand minute parts of both the Start and OTRateBegins, and using theminstead? For some reason, (probably paranoia!), I am suspicious of theCONVERT function.Apologies for not posting DDL, but I felt that the situation didn'treally warrant it.ThanksEdward
I am trying to write an SQL command for my crystal report. I need to compare the same column in 3different tables & get the data from each table for only the matching data.. I understand I need to create a temporary table, get the data into it & then work around.. I am quite new to SQL.
Eg: Considering one customer account Table 1 Cust.No Name Amt_Counter AmtPaid 123.456 sam 0 0 123.456 sam 1 50
Table 2 Cust.No Name Freq_Counter Frequency 123.456 sam 1 0 123.456 sam 2 15
I've been working with T-SQL in a MSSQL Server Management Studio (2005) for about a week now. I've been trying to convert some horribly written VB code from a MS Access DB over to SQL so it can be automated on a SQL backend.
Most of the learning process and coding has gone surprisingly well. The problem is with comparing some data to determine which one needs to be flagged.
Three tables to note in bold, with notable fields in italics below them:
EmployeeData HRID (identity)
ResourceAllocation ID (identity) [Last Name] (linked to HRID) Project [Resource Start Date] [Resource End Date] [Percent Utilization]
tblHCvalues RAID (linked to ResourceAllocation.ID) a monthyear and quarteryear for every month and quarter from 2012-2014. IE january12, february12, 1q12, 2q13, etc...
And yes, there are probably a thousand ways to optimize that tblHCvalues, but I'll ask about that later. Just work with the structure I have
Here's how it works: Each employee's data and unique HRID is in the EmployeeData tableAn employee can be on one or multiple projects at any timeThose projects are stored per project in the ResourceAllocation table with a link to the Employee's HRID, and all the other information listed aboveEven though an employee might be on two projects, they can only count for headcount on one project.
We use rules that compare the percent of work being done on a project, and the start and end dates of the employee (resource) on that project to determine which project should be counted for Headcount. The code uses a cursor to go through each HRID, and then pull up all the ResourceAllocation records associated with it.Run the rules to determine which ResourceAllocation record counts toward headcountA stored procedure then runs that fills out the tblHCvalues in the way we want for the project we want
All of it works, except for the rules that compare the things, so that's what I want to focus on in this thread. How do I write these rules:
Here are the rules, and they should work for any number of multiple resource allocations for one employee:
Choose the ResourceAllocation with the greatest [Percent Utilization]If the top ResourceAllocations have equal [Percent Utilization], choose the ResourceAllocation with the earliest [Resource Start Date]If the [Percent Utilization] and the [Resource Start Date] are equal, choose the latest [Resource End Date]If all three fields are equal, choose the first ResourceAllocation (aka, screw it and pick one at random)
I'm sure I could use a bunch of IF statements to compare it all, but even that is complicated to think about. There has to be an easier way, right?

If you look above, I need to sum the AMOUNT and VAT columns and get a value for each ID, then compare the two tables and get the ID's that have different values...in this case I would need a result saying ID1 as the total of INV TABLE ID1 (23.021) is different to the corresponding ID1 row in COST TABLE (24.946)

Im Working with stored procedure. How can i compare Columns with specific values. I want to get the greater values of those column and inserted it to other columns. i want something like these CASE WHEN a> b,c,d THEN a WHEN b> a,c,d THEN b WHEN c> a,b,d THEN c WHEN d> a,d,c THEN d
is there any ways to implement this? i got an error.. thanks please help..
I would be very grateful if someone could help me. I have very little SQL knowledge and would like a push in the right direction:
I have a application that receives GPS lattitude and longitude values. I was originally using file base system where I would load all the points from the file into memory and do the calculations in the software but I now would like to use SQL Server Express.
I have created the tables:
[Table 1] GPS Points: id int Primary key latitude real longitude real desc nvarchar(128)
[Table 2] GPS Locations (comprises of one or more GPS Points from [1] above) to form a boundary: GPS Locations database structure is: locationId int primary key gpspoint1 int gpspoint2 int gpspoint3 int gpspoint4 int desc nvarchar(128)
Table 2 contains up to 4 gps points ids from table 1 and GpsPoints1-4 can be null.
I have created the tables and I have inserted GPS values into both tables.
My problem: I am trying to compare the current Lat/Lon (which are passed into the SQL fuction as two real datatype value) and I want to return all Table 2 locationId's where the current Lat/Lon are withing GPSPoints1-4 area. gpspoint1, gpspoint2, gpspoint3, gpspoint4 reference an id from Table 1. I am not sure how I can do this?
I have implemetned a SQL function that returns all points from Table 1 that are within the predefined radius of 1.5 miles from the current Lat/Lon values passed in.
where 3963.191 is earths radius in miles, radius is 1.5, @LatDec is the current latitude and @LonDec is the current longitude
Uses a lot of Trig and (for me) is quite complicated. This works very well and is very accurate. It also only uses a single table. I want to be able to now look for the current position within a boundary of 3 or more positions from Table 1 and this is where I am struggling?
Also, any suggestions on how I could do this better would be very much appreciated?
Hello I have two matrices. One contains sales data for the current year, the other prior year. Both matrices use different data sets
I'd like to compare the two - possibly by creating a third matrix that subtracts prior year from current year.
Any ideas? When I create a third matrix and substitute a formula like =sum(values, "Data source for matrix 1") - sum(values, "Data source for matrix 2"), the resultant matrix subtracts the grand total from the first matrix - not the individual "cell".
Hi,I have 2 tables and each has a text column. When i compared the 2columns with the LIKE operator i found something strange.create table test1( var1 text )create table test2( var1 text )insert into test1 values ( '-- [ CustomerType = 1 ]' )insert into test2 values ( '-- [ CustomerType = 1 ]' )select * from test1, test2where test1.var1 like test2.var1The last query surprisingly did not return any results. However when itook of the '[' in the text data and had something like thisinsert into test1 values ( '-- CustomerType = 1 ]' )insert into test2 values ( '-- CustomerType = 1 ]' )the query returned expected results, showing one row.any helpful would be great.Regards,Arun Prakash.

I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?
