Transact SQL :: CASE With Subselect And DATEADD Function Returning NULL Values
Jun 15, 2015
I'm running the following test query on a single table:
SELECT sph.datestamp, sph.stocksymbol, sph.closing, DATENAME(dw, sph.datestamp),
CASE DATENAME(dw, sph.datestamp)
WHEN 'Monday' then 'Monday'
ELSE (SELECT CAST(sph2.datestamp AS nvarchar) FROM BI_Test.dbo.StockDB AS sph2 WHERE sph2.DateStamp = DATEADD(d, -1, sph.datestamp) AND sph2.StockSymbol = 'NYA')
END AS TestCase,
[Code] ....
And here's an example of the output I'm getting:
Why the exact same subquery in the THEN of the second CASE statement is returning NULL when the first one completes as expected?
I have tables and a function as representated by the code below. The names for objects here are just for representation and not the actual names of objects. Table RDTEST may have one or multiple values for RD for each PID. So the function GIVERD will return one or multiple values of RD for each value of PID passed to it.
When I run the following query, I get the required result except the rows for CID 500 for which PID is NULL in table T1. I want the rows for CID 500 as well with PID values as NULL.
SELECT A.CID, A.ANI, A.PID, B.RD FROM T1 AS A CROSS APPLY GIVERD(A.PID) B
I'm trying to return a query based on the dateadd function. I have a column in the database called date_added which is am successfully using the the DATEADD function above as date1. The Var1 variable I need to populate from the database too from a column called life_span which is an int data type. The error I get is An expression of non-boolean type specified in context where a condition is expected near select
My query is as follows: select guid, dateadd(day,life_span,date_added) as datepayday. From User_table
Hello again! I'm having yet another problem with my code.
CASE Kit WHEN 'Y' THEN '(Kit)' WHEN 'N' THEN '' END + ' ' + CASE cream WHEN 'Y' THEN '(cream)' WHEN ' N' THEN '' END + ' ' + CASE Phone WHEN 'Y' THEN '(Phone)' WHEN 'N' THEN '' END
The problem that I am running into is that if one of the values comes up as NULL the whole field is NULL. am i doing something wrong?
I have a simple table on my webpage which shows data from my database. It all worked fine apart from one part. I wanted the select statement to select only NULL values from a column, as these are classed as open queries. Once I have closed the query a 0 or 1 will automatically be posted and will no longer have a NULL value. I have a simple select statement (which I will post on here when I log in with my work computer) and at the end I have a WHERE Column = NULL. I have also tried WHERE column <> 0.0 AND column <>1.0 and that did not work. If I only did WHERE column <> 1.0, i only get the 0.0 results and none of the NULL results, but if I have no WHERE statement I get all the results including the NULL values.
i have a stored procedure that has parameters. this dataset is used in a crystal report. the parameters are in the sp and will return records if a value is selected. i would like to return records if one parameter or all parameters are selected. there are 3 parameters, date range, receipt, po # if i select a distinct value and leave the others null, or 2 values 1 null etc, i would like to return the records, i am having trouble with the syntax. thank you
I have this assignment where i have a table full of two digit exam scores and I have to write a function that eliminate x number of top values and x number of bottom values and return all the middle values. When the function is called, obviously a number is entered such as 3 and the top 3 and bottom 3 scores are not returned. i.e. SELECT * FROM GetMiddleValues (3);
If anyone has any ideas on how to accomplish this, that would be great.
SELECT NAME, CASE WHEN PHONE IS NULL THEN '-' ELSE PHONE END AS PHONE FROM PATIENT WHERE PHONE = '-'
If I am switching the NULL values to hyphens (-), why am I not getting any records when I look for hyphens in the WHERE clause? The script is not as simple as this or else I would just check for NULL values. I really need to switch NULL values to something I can pass on to a variable and query on it from Reporting Services.
I have a table that keeps track of all changes that were performed in an application. There is a column called "old value" and column called "new value". There are some values in the application that don't require data therefore the "old value" or "new value" values can be empty. These columns are an nvarchar data type because the value can be text or numbers or dates. An example is "ReceivedDate". There is a report that is generated based on this table.
What is happening is the query in the report dataset is adding dates when it should be displaying empty. They query is using "CASE/WHEN/THEN". What I need is "When the column is "RecievedDate" and it is not null then convert it to a date". This is for formatting purposes.
This is an example of the table:
UpdateColumn Old Value New Value ReceivedDate 7/8/2015 5:00:00 AM ReceivedDate 7/8/2015 12:00:00 AM 7/9/2015 5:00:00 AM ReceivedDate 7/9/2015 12:00:00 AM
So, the first time it was updated there was no value but it was replaced with July 8, 2015 and so on.This is what the report is displaying
This is the query:
CASE UpdateColumn ... WHEN 'ReceivedDate' THEN (replace(convert(varchar(11),CONVERT ( date, oldvalue ), 106), ' ', '-') ) ... I tried adding CASE UpdateColumn ... WHEN 'ReceivedDate' IS NOT NULL THEN (replace(convert(varchar(11),CONVERT ( date, oldvalue ), 106), ' ', '-') ) ...
I have a sqldatasource, and on the selectcommand I'm trying to use a case statement with a subselect. The case statement works fine without the subselect, but I'm trouble getting it to work with the case statement. Could you help me with the syntax? ThanksSelectCommand=" SELECT DISTINCT RecipeID, Title FROM [Recipes] WHERE (CASE WHEN @Type='Appetizer' THEN Appetizer WHEN @Type='Pies' THEN (Select Distinct RecipeID, Title From Recipes WHERE Title like '%Pie%') WHEN @Type='Beverages' THEN Beverage WHEN @Type='Dessert' THEN Dessert WHEN @Type='Kids' THEN Kids WHEN @Type='Side' THEN Side WHEN @Type='Soup' THEN Salad WHEN @Type='Main' THEN Main WHEN @Type='Breakfast' THEN Breakfast END) = 1"
I am writing a query and have the bulk of it already written.
I am looking at a table that contains customer orders. There is a column named Customer_Order.Status Available values for this column is R, F, H, and C.
I'd like for my query to return all lines that have the value R, F, H.
My where clause is written like this
WHERE CUSTOMER_ORDER.SITE_ID = 'XXX' AND CUSTOMER_ORDER.STATUS = ('R','H','F')
I am using Visual Web Developer Express 2005 and SQL Server Express 2005. I have set up a trigger that fires when an update has been performed on a specific table. The trigger checks to see if specific columns have been updated. If they have, then the trigger code is executed. This part works fine. I am now trying to find a way to check if null values exist in either one of two field from the same table. If either field contains a null value, then I don't want the trigger code to be executed. How can I check for null values and skip a block of code within my Transact Sql trigger. Thanks.....
I'm trying to do a Clr function wiht null values but I have an error. My Clr is like this:
using System; using System.Data; using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server; using System.Collections; using System.Text;
[code]...
A .NET Framework error occurred during execution of user-defined routine or aggregate "function":
System.InvalidCastException: La conversión especificada no es válida. System.InvalidCastException: en Microsoft.SqlServer.Server.ValueUtilsSmi.GetSqlInt16(SmiEventSink_Default sink, ITypedGettersV3 getters, Int32 ordinal, SmiMetaData metaData) en UserDefinedFunctions.function()
I have a CLR function that throws an error if one of the parameters is NULL. Am I using the IsNullable tag correctly or am I supposed to do this another way? The function simply formats decimal values using .NET culture information and returns a string. Thanks very much for any help. -- Erik
I have tried all possible combinations of changing this. But was not able to make the results tally.I am giving you a part of the query, there are others queries involving 4 tables which are based on this same temporary table query.
SELECT c.juris_id, b.jrnl_mo_yr FROM a_trueup a, #t_mths b, r_rj c WHERE a.rlzd_mo_yr =* b.jrnl_mo_yr AND a.juris_id =* c.juris_id

Problem: I have two nearly identical querys that are running. One of the query's is using the SQL DATEADD function. These query's are running on a SLQ2005 MSDE. There is now service pack four applied to this server. The question is: Are there any known issues with the DATEADD function in SQL 2005? This query is used in a report that has been in use for about two years. There were some changes made to the server (BIOS upgrade) including adding this service pack. These changes did not cause any other SQL issues. This query now takes almost five minutes to run. The nearly identical query (the difference is the date is passed in as a parameter rather than using the DATEADD function) takes from one to two seconds. These reports have a history of nearly identical running time.
What is a good way to try and correct the issue or at least to try and isolate the problem? Have there been any known issues with this function?
How is the best way to make a function for summing an arbitrary number of times values (table parm?)- I 've read it's necessary to convert to seconds, sum then convert back, but Im' wondering if there's an alternative.
Here's the example I want to sum: 00:02:01:30 00:01:28:10 00:01:01:50 00:06:50:30 00:00:01:50
I've to write a function to return a comma delimited values from a table columns
If a table has Tab1 ( Col1,Col2,Col3).
E.g. as below ( the columnName content I want to use as columns for my pivot table
CREATE FUNCTION [RPT].[GetListOfCol] ( @vCat NVARCHAR(4000) ) RETURNS @PList AS BEGIN SELECT @PList += N', [' + [ColumnName] +']' FROM [ETL].[TableDef] WHERE [IsActive] = 1 AND [Category] = @vCat RETURN; END;
I want out put to be as below, I am getting this output from the select query independently by declaring @Plist variable and passing @vcat value, now I want it to be returned from a function when called from a select query output ,Colum1,column2,....
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?
