SQL 2012 :: Join Removing NULLS That Need To Be Displayed?
Apr 22, 2014I have a table named item that looks like this:
PartNumberDescriptionI.DateCreated
1A1XXX ALPHA1 1/1/2014
2A2XXX ALPHA2 1/5/2014
3A3XXX ALPHA3 1/12/2014
1B1XXX BRAVO1 1/22/2014
2B2XXX BRAVO2 1/28/2014
3B3XXX BRAVO3 2/2/2014
And a second table named orders that looks like this:
OrderNoPartNumberQtyO.DateCreated
1CHXX1 1A1XXX 2 1/8/2014
1CHXX2 2A2XXX 3 1/8/2014
1CHXX3 2A2XXX 1 1/20/2014
2CHXX1 1B1XXX 4 2/10/2014
2CHXX2 2B2XXX 2 2/10/2014
2CHXX3 2B2XXX 1 2/22/2014
I need to pull all records from the Item table and then I need to populate the most recent OrderNo and O.DateCreated. I got this far but if there is a part in the item table that does not have an order against it, I do not get a value and my goal is to see any parts that have not been ordered in the last year. Something like this:
SELECT I.PartNumber, I.Description, I.DateCreated
FROM item I
CROSS APPLY (SELECT TOP 1 O.OrderNo, O.DateCreated
FROM Orders O
WHERE O.PartNumber = I.PartNumber ORDER BY O.DateCreated DESC) O
PartNumberOrderNoO.DateCreated
1A1XXX 1CHXX1 1/8/2014
2A2XXX 1CHXX3 1/20/2014
3A3XXX NULL NULL
1B1XXX 2CHXX1 2/10/2014
2B2XXX 2CHXX3 2/22/2014
3B3XXX NULL NULL
SQL Server 2008 :: Summarizing Transaction Data Removing Nulls?
Oct 27, 2015I have two tables one list changes of hospital ward and one lists changes of consultant doctor. These can change independently ie a ward change can occur without a consultant change and vice versa. I want to summarise these changes to give the status at each date_serial value.
create table #temp_ward_stay(date_serial bigint,ward_id varchar(10))
;
insert into #temp_ward_stay
values
(201501021200,'W1'),(201501031201,'W2'),(201501091200,'W3'),(201501161200,'W4'),(201501161201,'W5')(201501271200,'W3'),(201502101200,'W5')
;
create table #temp_consultant_episode(
date_serial bigint,
consultant_id varchar(10))
;
insert into #temp_consultant_episode values
(201501021200,'C1'),(201501031200,'C2'),(201501031201,'C3'),(201501091201,'C4'),
(201501121200,'C3'),(201501301200,'C6'),(201502111200,'C6'),(201502111201,'C7')
;
If I use:
select date_serial,consultant_id,null as ward_id from #temp_consultant_episode
union
select date_serial,null as consultant_id,ward_id from #temp_ward_stay
I get:
date_serial ward_id consultant_id
-------------------- ---------- -------------
201501021200 NULL C1
201501021200 W1 NULL
201501031200 NULL C2
201501031201 NULL C3
201501031201 W2 NULL
201501091200 W3 NULL
201501091201 NULL C4
201501121200 NULL C3
201501161200 W4 NULL
[code].....
whereas what I actually want is:
date_serialward_idconsultant_id
201501021200W1C1
201501031200W1C2
201501031201W2C3
201501091200W3C3
201501091201W3C4
201501121200W3C3
201501161200W4C3
201501161201W5C3
[code].....
I can see how I could remove the nulls where the date_serial values are the same:
select ce.date_serial,ward_id,consultant_id from #temp_consultant_episode ce
join #temp_ward_stay ws
on ce.date_serial=ws.date_serial
but I can't see how to move forward from here.

Multiple NULLs In A Table
Apr 5, 2004To make the long story short, we have a situation where there can be different datatypes for a column. For example, 'AttributeValue' can be a datetime, int, float etc. My DBA is suggesting the following design,
tblAttribute
AttributeId, AttributeDataTypeId, AttributeValueInt, AttributeValueFloat, AttributeValueDateTime etc
For any AttributeId, only one of the value columns will have a value and the rest will be NULLs. I feel that this is a bad design. (FYI, We decided against SQLVariant for specific reasons). I have suggested, we create a seperate table for each datatype, like
tblAttribute: AttributeId, AttributeDataTypeId
tblAttributeValueFloat: AttributeId INT, AttributeValue FLOAT
tblAttibuteValueDateTime: AttributeId INT, AttributeValue DATETIME
etc for each datatype.
Depending on the AttributeDataTypeId in the Attribute table go to the specific table and pick up the value. This way, we don't need to have too many NULLs in a row. Which of the 2 do you think is a better design? And if you agree with me, what would be the points to support it.
Your time is greatly appreciated
Inserting Nulls Into A Temp Table
Mar 3, 2008I'm trying to insert any null values into a temp table. I'm storing the ixo_rlt_code as OldRole, and 'Other' as NewRole. I need both the ixo_rlt_code as OldRole and 'Other' as NewRole in the temp talbe in order to run an update I'm writing.
I know a case statement isn't necessary here, but this section is only one small part of a larger script, so I just used it to be consistent, and it will be easier to make any future changes this way. Below is my code and the error message I'm getting...
select
ixo_key,
ixo_title as Title,
ixo_rlt_code as OldRole,
CASEWHEN ixo_title is null
or ixo_title = ''
or ixo_title = ' '
or ixo_title = ' ' THEN 'Other'
END as NewRole
from
co_customer (nolock)
join co_individual_x_organization (nolock) on ixo_key = cst_ixo_key --and ixo_delete_flag = 0
where
cst_delete_flag = 0
and cst_type = 'Individual'
and ixo_rlt_code is null
This is the Error Message I get:
Server: Msg 515, Level 16, State 2, Line 1095
Cannot insert the value NULL into column 'NewRole', table 'tempdb.dbo.#temp_______________________________________________________________________________________________________________00000001698C'; column does not allow nulls. INSERT fails.
The statement has been terminated.
Thanks ahead of time for any help/suggestions
Newbie Question... How To Remove NULLs In Table
Jul 6, 2006I apologize if this has been posted/asked before... a search of the Forum for keyword "NULL" doesn't return any result (not even a 0 found).
When I import an XLS file into SQL2000, everything goes fine, except that every column after my data has <NULL> in it. How do I prevent this from happening, or fix it?

Multiple Data Types In One Table With Nulls
Sep 25, 2013Our database stores vehicle data in one table, but 3 different types of data are stored in the one table. The table contains all the columns for all 3 types so when you query the table you get at least 3 rows back with null values for all the columns that don't apply to that record. The data is imported to the table when it's updates so there's a possibility that they're updated at different times so they have a different BATCH like:
BATCH TYPE ID RATING INSURANCE SAFETY
300 SAFE 123 NULL NULL A
300 INS 123 NULL YES NULL
250 RATE 123 A NULL NULL
What I'd like returned is:
ID, RATING, INSURANCE, SAFETY
123 A YES A
I'm trying to do a case statement to pull the data down, but I keep ending up with multiple rows because of all the nulls. I tried doing a SUM of the case statement with an ISNULL(SAFETY,0) but I can't SUM char values. I can probably do this with 3 temp tables to load the data that I want for each TYPE into them and then select and join them together, but is there a better way to do this?

Inserting Nulls In To Table Conflicting With Rule
Jan 15, 2007Hi,I basically have two tables with the same structure. One is an archiveof the other (backup). I want to essentially insert the data in to theother.I use:INSERT INTO table ( column, column .... )SELECT * FROM table2Now, table2 has a rule on various columns:@CHARACTER IN ('Y','N')but the column allows nulls, in the design view is says so anyway.When I run this query I get:A column insert or update conflicts with a rule imposed by a previousCREATE RULE statement. The statement was terminated. The conflictoccurred in database 'database', table 'table', column 'column'.The statement has been terminated.Obviously, I've changed the names of everything.The only data in those columns which could possibly conflict with therule is the NULL value. Any ideas why this doesn't work?Thanks.

Removing Duplicates In The Table
Mar 21, 2014The database has Name,Email, and skill. Though the name is distinct it is repeated as it has different skills. I would like to remove duplicate names and add the corresponding skill to the only one row.
From the stored procedure, combining 3 tables I got the output as:
NameemaildepartmentSkill
ArunemailidTech teamTechnical
ArunemailidTech teamLeadership
ArunemailidTech teamDecision Making
BinayemailidMarketingTechnical
BinayemailidMarketingDecision Making
I would like to remove the duplicate Name fields and combine the Skill in a single row as other fields are same.
So the output should be
NameemaildepartmentSkill
ArunemailidTech teamTechnical, Leadership, Decision Making
BinayemailidMarketingTechnical,Decision Making

Removing Replication Table
Oct 12, 2005Hi all,
View 10 Replies View RelatedDo Not Keep NULLS Using SSIS Bulk Insert Task - Insert Empty Strings Instead Of NULLS
May 15, 2008I have two SSIS packages that import from the same flat file into the same SQL 2005 table. I have one flat file connection (to a comma delimited file) and one OLE DB connection (to a SQL 2005 Database). Both packages use these same two Connection Managers. The SQL table allows NULL values for all fields. The flat file has "empty values" (i.e., ,"", ) for certain columns.
The first package uses the Data Flow Task with the "Keep nulls" property of the OLE DB Destination Editor unchecked. The columns in the source and destination are identically named thus the mapping is automatically assigned and is mapped based on ordinal position (which is equivalent to the mapping using Bulk Insert). When this task is executed no null values are inserted into the SQL table for the "empty values" from the flat file. Empty string values are inserted instead of NULL.
The second package uses the Bulk Insert Task with the "KeepNulls" property for the task (shown in the Properties pane when the task in selected in the Control Flow window) set to "False". When the task is executed NULL values are inserted into the SQL table for the "empty values" from the flat file.
So using the Data Flow Task " " (i.e., blank) is inserted. Using the Bulk Insert Task NULL is inserted (i.e., nothing is inserted, the field is skipped, the value for the record is omitted).
I want to have the exact same behavior on my data in the Bulk Insert Task as I do with the Data Flow Task.
Using the Bulk Insert Task, what must I do to have the Empty String values inserted into the SQL table where there is an "empty value" in the flat file? Why & how does this occur automatically in the Data Flow Task?
From a SQL Profile Trace comparison of the two methods I do not see where the syntax of the insert command nor the statements for the preceeding captured steps has dictated this change in the behavior of the inserted "" value for the recordset. Please help me understand what is going on here and how to accomplish this using the Bulk Insert Task.

Process For Removing Duplicates In Table?
May 18, 2012I have a very large table that can contain up 3 to 5 duplicate records. Every month around 100,000 new records come in. Sometimes it's an ammended record, other times is just duplicated by error.
Is it possible to keep the latest record dumped into the table and delete the others? Does SQL track the order of the data being dropped into the table?
The layout would look like this. There are 10-15 other columns in the table where adjustments can also be made.
Lease# Year Month Production
12345 2008 10 1,231

Jul 29, 2015I've look at several different methods for removing leading zero's from a column but I need to remove trailing data from a VARCHAR column. For some reason, the old database saved the time along side the date in my client's app.
For example:
The old database format "2015-07-28 00:00:00"
I need the data in this column in the new database to only be the date "2015-07-28", there are alot of rows with this issue.
Is there a query I can run to remove the 00-00-00 from all of the rows? Some of the fields actually have a time in there like this: 2015-07-28 12:15:35, with this one, I don't think it's going to be easy but if I could at least remove the 00-00-00 from all the rows that have it, that would be a good start.
Removing Blank Space Caused By Wide Table
Apr 5, 2007Hi all,
Report:
-For instance 2 small tables (eg. width 10cm = 3 inch?)
-And one wide table (eg. width 30cm = 10 inch?)
All separated by "insert pagebreak after table".
Problem:
When rendered, the pages with the small tables on have a lot of white blank space at the right of the table. This is probably caused by the big table on page 3.
This report is distributed by email in Excell format. So on sheet 1 and 2 there are a lot of white cells on the right of the tables. When trying to print, they just want to use the "landscape" option and the "fit to page" option. Because of the empty white cells, the fit to page option reduces the first 2 tables to a very small table which covers only 50 % of the page width. The other 50 % is reserved for the empty cells.
Off course, I know that deleting the empty cells offers a solutions, but it would be a lot more handier if there were no empty cells in the first place.
Anybody with a solution?

Above code i try to delete records batch by batch to avoid table locking at BCDR table.total records in this BCDR table is 40,000 records. However I run the code at execution plan, the BCDR table still clustered index scan which means that the locking still happend.
If i change the delete top (5000)...... to delete top (5).... then thre is clustered index seek, which is good..The problem here is each time only delete top 5 records which is means it will realy take very long time to remove those data.
how to cater the situation inorder for me to delete those huge data without table locking happend. If table locking happend , then other user will not be able to access this table at the same time.
