SQL Server 2012 :: Get List Of Last Non Null Values
Feb 10, 2014
I have two tables, a dates table and a values table. They are joined on the date column.The date table has a range, say from today as far as 20 days from now, incrementing by 1 day each row.The values table may have a row for a day, and may not. If the day has a value I want to display that value.If the day does not have a value in the values table I want to display the last known value.
I think this can be done with windowing functions in a set based manner but have not been able to work it out. I have done it procedurally but im not happy with that at all, and really want to see if this is possible in a set based manner.Below is some simplified code to allow testing with sample data.
create table DimDate
(
DateCol date
)
create table TotalsData
(
DateCol date
SET NOCOUNT ON; DECLARE @items TABLE (ITEM_ID INT, ITEM_NAME VARCHAR(10)) INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 10,'ITEM 1' INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 11,'ITEM 2' INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 12,'ITEM 3' INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 13,'ITEM 4' INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 14,'ITEM 5' INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 15,'ITEM 6' INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 16,'ITEM 7' INSERT INTO @items (ITEM_ID, ITEM_NAME) SELECT 17,'ITEM 8' SELECT * FROM @items
-- table with categories
SET NOCOUNT ON; DECLARE @categories TABLE (CAT_ID INT, CAT_NAME VARCHAR(10)) INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 100,'WHITE' INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 101,'BLACK' INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 102,'BLUE' INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 103,'GREEN' INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 104,'YELLOW' INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 105,'CIRCLE' INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 106,'SQUARE' INSERT INTO @categories (CAT_ID, CAT_NAME) SELECT 107,'TRIANGLE' SELECT * FROM @categories
--table where categories are assigned to master categories
SET NOCOUNT ON; DECLARE @master_categories TABLE (MASTERCAT_ID INT, CAT_ID INT) INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,100 INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,101 INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,102 INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,103 INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 1,104 INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 2,105 INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 2,106 INSERT INTO @master_categories (MASTERCAT_ID, CAT_ID) SELECT 2,107 SELECT * FROM @master_categories
-- items-categories assignment table
SET NOCOUNT ON; DECLARE @item_categories TABLE (CAT_ID INT, ITEM_ID INT) INSERT INTO @item_categories (CAT_ID, ITEM_ID) SELECT 100,10 INSERT INTO @item_categories (CAT_ID, ITEM_ID) SELECT 105,10 INSERT INTO @item_categories (CAT_ID, ITEM_ID) SELECT 100,11 INSERT INTO @item_categories (CAT_ID, ITEM_ID) SELECT 105,11

So now I need to query the table @t4 in and to determine the items that are assigned to category 'WHITE' in master category 1 and to 'CIRCLE' in master category 2.The important thing is to return items that are assigned solely to 'WHITE' in master cat 1 and solely to 'CIRCLE' in master cat 2.In the above example it would be only the ITEM 1 (id=10) that is returned:
1. ITEM 2 (id=11) is not returned because it has the assignment to category 'SQUARE' in master cat 2 additionally
2. ITEM 3 (id=12) is not returned because it has the assignment to category 'BLACK' in master cat 1 additionally
3. ITEM 4 (id=13) is not returned as it does not have assignment to category 'CIRCLE' in master cat 2 but only to 'WHITE' in master cat 1
3. ITEM 5 (id=14) is not returned as it does not have assignment to category 'WHITE' in master cat 1 but only to 'CIRCLE' in master cat 2
So at the moment, I don't have a function by the name CONCATENATE. What I like to do is to list all those different values that go with a single CASE_ID to appear as a a comma separate list. You might have a better way of doing without even writing a function
The following t-sql 2012 works fine in sql management studio. However when I place it in a .net 2010 web form application, I am told the sql does not work when the parameter values are null. Thus can you tell me what I can change in the sql below that will accept null as 3 possible input values?
CREATE TABLE A (ID INT IDENTITY (1,1)) CREATE TABLE B (ID INT, EMPID VARCHAR(10)) INSERT INTO A DEFAULT VALUES GO 5 INSERT INTO B VALUES (1,'E23') INSERT INTO B VALUES (1,'E24') INSERT INTO B VALUES (2,'E23')
from the above code i would like to get output like
Question in review today is Creating a Report showing the FName, LName of all Employees not Specified in a region; I would assume "No Value to be Null" Correct?
Or is there another way for me to do this?
This is what I have so far...What am I missing that this is not showing me results?
Select Firstname, Lastname, Region From Employees WHERE Region LIKE 'null%';
SELECT event_data.value('(event/data/value)[4]', 'bigint') AS cpu_time, --database name event_data.value('(event/data/value)[5]', 'bigint') AS duration, --estimated cost --estimated rows --nest level
[code]...
Basically, is a simple T-SQL query that reads the local file for my already setup extended event sessions. But I can't find the way to retrieve the following attributes as part as the T-SQL query:
--database name --estimated cost --estimated rows --nest level --object name
I am trying to find a BOL or some MS link with the full list of possible values for event_data.value but can't find one.
I wrote a select statement, I only want to see orders with max lastUpdatedOn date of 14 days and older. Now my results show dates with all orders of 14 days and older (which is OK), but all others are displayed in the "Uitgifte" column as "NULL". But those orders should not be displayed at all.

I need to list all students who have both parents phone number is null. The parent relationship values 1 and 2 indicates the person is either Mom (value 2) or dad (value 1) of the student. Note: I am using student parent as an example to write my query.
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 need to replace all the "User Friendly Names" with "System Names" in the calculations, i.e., I need "Sales Units" to be replaced with "cSalesUnits", "AUR" replaced with "cAUR", "Comp Sales Units" with "cCompSalesUnits", and "Comp AUR" with "cCompAUR". (It isn't always as easy as removing spaces and added 'c' to the beginning of the string...)
I have created a CTE of all the "Look-up" values, and have tried all kinds of joins, and other functions to achieve this, but so far nothing has quite worked.
How can I accomplish this?
Here is some SQL for set up. There are over 500 formulas that need updating with over 400 different "look up" possibilities, so hard coding something isn't really an option.
Following SQL Statement is from BOL 7.0 and it doesn't return any data. But when I change the where clause to "WHERE advance IS NULL" it works. I am trying to do something like this in my own stored procedure. It works fine in 6.5 both ways. Is there any parameter to set? or any other problem. Thanks in advance.
SELECT title_id, type, advance FROM pubs.dbo.titles WHERE advance = NULL
I am importing an excel spreadsheet into tables in a sql server database using dts. I have one row of information filled out in the excel spreadsheet, but when the dts runs, it imports the information plus 5 extra rows filled with nulls ino the table.

If myDateTimeColumn contains a <NULL> value. How do you handle that when reading into a DateTime object in your code?DateTime myDate = Convert.ToDateTime(dr["myDateTimeColumn"]);Does not work, it throws: System.InvalidCastException: Object cannot be cast from DBNull to other types. I am curious as to what others are doing to handle this?
I have about 100 K records of the form below in Example 1 and I would like to turn them into the form of Example 2, basically turn the entries in field2 into a coma separated list of values sorted by field1.
I have attached some test data for you that has two temp tables "#worker" and "#worker_rate".
The issue is to find all workers who are sharing SAME SET of rate_codes.
I'm able to get the output as "workers sharing same rate_codes", but unfortunately I could not get the list of workers sharing same SET of rate_codes. Also definition of SAME SET is not defined.
Hello,I am trying to import a CSV file into my SQL Server database, this file was originally generated by another database table (on another server) with the same structure, the table contains two columns of real datatype with Allow Null Value setto true for those columns, the CSV file contains the value NULL for theses columns, I am facing a problem when importing this file. This may be because DTS tries to represent values as strings then to convert them to real datatype which results in transforming the value "NULL" to real, I receive an error message saying.Error during Transformation 'DirectCopyXform' for Row number 1. Errors encountered so far in this task: 1. TransformCopy 'DirectCopyXform' conversion error: Conversion invalid for datatypes on column pair 8 (source column 'Col008' (DBTYPE_STR), destination column 'zip_longitude' (DBTYPE_R4)). TransformCopy 'DirectCopyXform' conversion error: Conversion invalid for datatypes on column pair 7 (source column 'Col007' (DBTYPE_STR), destination column 'zip_latitude' (DBTYPE_R4)).How can I work around this problem? Any help would be appreciable
I am stuck on a query where I need to display all the month year values even if the corresponding count_booking values are NULL. The requirement is to display the 13 month year period from current date.
For e.g. if the date exists in the current month then starting from May 15 go all the way back to Apr 14.
My current query works in terms of displaying all the 13 months if the count_booking values exist for all the months. However, if some months are missing the values then those months don't show up.how to display all the months even if the values are NULL ? Query below:
SELECT COUNT(m.BOOKING_ID) AS count_booking, LEFT(DATENAME(MONTH, m.CREATE_DT), 3) + ' ' + RIGHT('00' + CAST(YEAR(m.CREATE_DT) AS VARCHAR), 2) AS month_name FROM MG_BOOKING AS m WHERE (m.CREATE_DT >= DATEADD(m, - 13, GETDATE()))
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?
I was just given an excel file with a list of 300 Stores.
I need to find out if these stores are selling our products and if they are , how many products they are selling.
One way of doing this , that I can think of right now is individually querying the Transactions table for each of the store in the excel sheet and then copy the results output back to the excel sheet.
Is there a way I can write a query against all the Store names from the excel file ? I need to get this done in the next few hours.
I have a Games table in a SQL Server 2012 database with game results from our league, including home and away scores, dates, and teams. How can I query to list streaks - that is, wins or losses of 2 more games in a row throughout a season?
