Need CASE Statement(s) To Populate 5 Fields Based On Values Of 2

Mar 10, 2008

I need to, ultimately, create a flatfile for exporting insurance information to a third-party vendor. Each individual is to have no more than 1 line per file, which contains their coverage information, if any, on 4 different type of insurance. What i need is for 2 fields in a table to determine the output for multiple fields in the flatfile.

What I have so far works, to an extent. If I have insurance types 1, 2, 4 (of types 1-4) required output is (__ = 2 blank spaces):



1A 1B 1C 1D 1E 2A 2B 2C 2D 2E 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E

== == == == == == == == == == == == == == == == == == == ==

Y N __ MD XX Y N __ MD XX N __ __ __ __ Y N __ DN XX



If they have coverage, A always = Y, B always = N, C always = blank(null), D is their ins. type, E is their cov. type(CASE statement). if they DON'T have that type of coverage, A always = N and the remaining field are NULL.



After a lot of work, and scouring a forum or 2, I attempted a whole lot of CASE functions. Below is an sample of code representing the 1x statements. This same code is repeated 4 times with the 1x being altered with 2x, 3x, 4x.



CASE HB.PLAN_TYPE

WHEN '10' THEN 'Y'

ELSE 'N' END AS 1A,

CASE HB.PLAN_TYPE

WHEN '10' THEN 'N'

ELSE ' ' END AS 1B,

' ' AS 1C,

CASE HB.PLAN_TYPE

WHEN '10' THEN HB.BENEFIT_PLAN

ELSE ' ' END AS 1D,

CASE HB.PLAN_TYPE

WHEN '10' THEN (CASE WHEN HB.COVRG_CD ='1' THEN 'XX'

WHEN HB.COVRG_CD ='2' THEN 'YY'

WHEN HB.COVRG_CD ='3' THEN 'ZZ'

ELSE 'WW' END)

ELSE ' ' END AS 1E,



It works to an extent. While the desires/required output it above, the output this produces (same scenario) is:



1A 1B 1C 1D 1E 2A 2B 2C 2D 2E 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E

== == == == == == == == == == == == == == == == == == == ==

Y N __ MD XX N __ __ __ __ N __ __ __ __ N __ __ __ __



1A 1B 1C 1D 1E 2A 2B 2C 2D 2E 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E

== == == == == == == == == == == == == == == == == == == ==

N __ __ __ __ Y N __ MD XX N __ __ __ __ N __ __ __ __



1A 1B 1C 1D 1E 2A 2B 2C 2D 2E 3A 3B 3C 3D 3E 4A 4B 4C 4D 4E

== == == == == == == == == == == == == == == == == == == ==

N __ __ __ __ N __ __ __ __ N __ __ __ __ Y N __ DN XX



While there is supposed to be 1 line, regardless of number of insurance types, it only produces 1 line per type. I first tried this in Access, and was able to get it to work, but it required multiple queries resulting in a crosstab, export to Excel and manually manipulate the data, export to text file to manipulate, import back into Excel to manipulate, import back into Access and finally export into a flatfile. Far too much work to produce a file which is why I'm trying to convert it to raw SQL.
Any assistance in this matter would be greatly appreciated.

CASE Statement And NULL Values

Oct 22, 2013

Code below:

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.

Case Statement On Where Clause If Parameter =NULL

Jun 3, 2008

I am working on a Function that takes multiple parameters. I have a query that populates a temporary table, and then it processes some logic. My question is, if the parameter is passed as null, I dont want the query to be affected by this null value. Rather, I would like to not pass it at all to the query. So if the parameter is NULL, dont pass it through the query. I have the following but its not compiling right:


SELECT bom.pEngr_BOM_ID , bom.fEngr_Item_ID, det.pEngr_BOM_Detail_ID, 1, bom.Bill_Type, bom.Rev_Ltr, bom.Series_Ltr
FROM dbo.Engr_BOM_Control bom WITH (nolock)
INNER JOIN dbo.Engr_BOM_Detail det WITH (nolock)
ON det.fEngr_BOM_ID=bom.pEngr_BOM_ID
WHERE bom.pEngr_BOM_ID=@v_pEngr_BOM_ID
AND det.fEngr_BOM_ID=@v_pEngr_BOM_ID
CASE WHEN @v_Bill_Type IS NOT NULL THEN
AND bom.Bill_Type=@v_Bill_Type
END

Need Help With Insert Statement On Table With Several Non-null Fields

Apr 30, 2007

On my aspx page I have a basic sqldatasource and gridview - both were set up using the wizards. The SQL Server 2000 database table that the sqldatasource is querying has some fields in it that are set to not allow nulls, however, the gridview control is not displaying all of the fields in the table - including some of the non-null fields.
My problem is, when I run an insert on the table from my aspx page, I get an error that says: "Cannot insert the value NULL into column 'ColumnName', table 'TableName'; column does not allow nulls. INSERT fails. The statement has been terminated."
The 'ColumnName', as you may have guessed, is one of the aforementioned columns that doesn't allow nulls, but isn't in the GridView.
How can I do an insert on this table without messing with the non-null fields. Those fields are relevant to the purposes of the gridview, so I don't want to display them, let alone allow editing of them.
Any suggestions on my options would be greatly appreciated!
Thanks

UPDATE Statement Creating NULL Fields?

Oct 23, 2014

I am attempting to update a table that drives a report. The report is at the order level. An order can have several types of demand (revenue $): Ship and/or Backordered. When I update one of these demand fields on the report table, I would expect those orders that have that type of demand to update, and those orders that don't have that type of demand to remain at their current value ($0 in this example which is the table default). But what is happening is that orders that don't have that type of demand are changing to NULL. What am i doing wrong with my update statement that is causing this?

Code:
CREATE TABLE #sales(
OrdNo int,
StatusGrp varchar(10),
Demand decimal(10,2)
)
INSERT INTO #sales
VALUES (1,'Ship',100.00)

Problem Using Result From CASE In Another CASE Statement

Nov 5, 2007

I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.

Previously, I had been duplicating the CASE logic for both columns, like so:




Code Block...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,
shipment_status_text =
CASE
[logic for condition 1]
THEN 'Condition 1 text'
WHEN [logic for condition 2]
THEN 'Condition 2 text'
WHEN [logic for condition 3]
THEN 'Condition 3 text'
WHEN [logic for condition 4]
THEN 'Condition 4 text'
ELSE 'Error'
END,
...remainder of SQL view...






This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.

This is what I'd like to do:



Code Block
...beginning of SQL view...
shipment_status =
CASE
[logic for condition 1]
THEN 1
WHEN [logic for condition 2]
THEN 2
WHEN [logic for condition 3]
THEN 3
WHEN [logic for condition 4]
THEN 4
ELSE 0
END,


shipment_status_text =

CASE shipment_status

WHEN 1 THEN 'Condition 1 text'

WHEN 2 THEN 'Condition 2 text'

WHEN 3 THEN 'Condition 3 text'

WHEN 4 THEN 'Condition 4 text'

ELSE 'Error'

END,
...remainder of SQL view...


This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.

Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?

Thanks,

Jason

Force Fields Upper-case

May 21, 2007

Almost all of our character fields are stored in upper-case. Is there an easy way to force SQL Server char and varchar fields to upper-case? Something I can do in SQL Server instead of in the client? It needs to apply to any new records.



There are some exceptions (email addresses for one). I don't mind going through each field and changing something.



Thanks!

Case Statement Error In An Insert Statement

May 26, 2006

Hi All,
I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance.
My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.

Here is my code:
Insert into myTblA
(TblA_ID,
mycasefield =
case
when mycasefield = 1 then 99861
when mycasefield = 2 then 99862
when mycasefield = 3 then 99863
when mycasefield = 4 then 99864
when mycasefield = 5 then 99865
when mycasefield = 6 then 99866
when mycasefield = 7 then 99867
when mycasefield = 8 then 99868
when mycasefield = 9 then 99855
when mycasefield = 10 then 99839
end,
alt_min,
alt_max,
longitude,
latitude
(
Select MTB.LocationID
MTB.model_ID
MTB.elevation, --alt min
null, --alt max
MTB.longitude, --longitude
MTB.latitude --latitude
from MyTblB MTB
);

The error I'm getting is:
Incorrect syntax near '='.

I have tried various versions of the case statement based on examples I have found but nothing works.
I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.

A More Complicated Case Of Insertion Filtering By More Than Two Fields

Feb 23, 2004

Hi,

I posted a problem some hours ago. I found that the solution that l was given by Karolyn was great, but at that time I didn't realize that my problem was a little bit more complicated. I'll rephrase my problem:

I need to insert some registers in a table. These registers have three fileds: col1, col2 and col3. I don't want to insert a register if in the table already exists a row with the col1, col2 and col3 combination of that register. These fields are PK, but I don't want to get errors. The problem is that I'm inserting a field that belongs also to the destination table. How can I filter a "destination" table by two fields in this case?

This the table1:

create table table1(
col1 int not null,
col2 int not null,
col3 int not null,
constraint PK_table1 primary key (col1, col2, col3)
)


Here's my "insert" code:

INSERT INTO table1
SELECT table2.col1, table3.col2, table1.col3
FROM table2, table3
WHERE table2.col1 = table3.col1


The third field in the SELECT now refers also to table1. Witch conditions should I add to avoid repetitions in table1 (avoiding also erroing)

Thanks

Check For NULL In CASE

SELECT whatever_field, CASE LEN(DrAccount)   WHEN 12 THEN DrAccount   ELSE CASE (Note1)     WHEN NULL THEN Location + DrAccount     ELSE Note1 + DrAccount     END   END AS Account FROM Table1 The purpose of the CASE(Note1) is when Note1 column is null, return Location+DrAccount. The actual result is when Note1 column is null, it always returns null, Location+DrAccount is not executed. When Note1 column is not null, it returns correctly Note1+DrAccount. The problem seems to reside in validating the null value in WHEN NULL How to check for null in CASE(fieldname) WHEN ???

Is there an way to do this for all fields instead of on an individual basis?
2.They don't want a null returned on any character string field.

If charge center is null, I need to ignore this field. How can I achieve this? The reason is that if any of the field is null, it will return ExpenseDesc as null.

Select When Some Fields Are Null...

Jun 5, 2008

Here is the problem that I am struggling with. The structure is:

States: StateID, StateName
Counties: CountyID, CountyName
Cities: CityID, CityName
Zips: Zip, StateID, CountyID, CityID
Regions: RegionID, RegionName
Region_Data: RegionID, StateID, CountyID, CityID

The thing about the region is that it can be defined by states only, in which case CountyID and CityId are NULL, can be defined by Counties too, in which case only CityID is NULL or it can be defined up to City level, in which case all 3 are set to something. Example, Northeast would be all cities from northeast, but Pocono would be just some counties in PA, and so on...

The issue is now selecting all cities that belong into a region... Normally I would join the Zips table with the Region_Data table and retrieve all CityIDs... The issue is that, as I said, the CountyID and CityID might be null for some records, so I am not sure how to retrieve them?

I came up with one idea in which I create 3 temporary tables and I select in them all the records that have 1) only state, 2) only state and county, 3) all 3, then I join each and I union the results...

But I am wondering if there is a way to do the select in one shot?

Any idea? I appreciate your help,

Thank you,

Iulian

Need Help With Filtering Fields With Null And More

Apr 26, 2006

Requirements:

1) Cannot have results in which both m.homephone & d.homephone are both null, or both m.workphone & d.workphone are both null in the result set

2) We also do not want to see any combos where one homephone is null and the other has only the char 0....same for workphone...no null & 0 combinations.

e.g.

m.homephone   d.homephone

null                       0

0                          null

The phone fields are varchar

I know this is hidiously wrong but is my first sloppy attempt at best:
select m.number, m.homephone as master_homephone, d.homephone as debtor_homephone, m.workphone as master_workphone, d.workphone as debtor_workphone
 
FROM master m
 
INNER JOIN debtors d ON d.Number = m.number
 
where (d.homephone <> m.homephone OR d.workphone <> m.workphone)
AND (d.homephone IS NOT NULL AND m.homephone IS NOT NULL)
AND (d.workphone IS NOT NULL AND m.workphone IS NOT NULL)
AND NOT ((d.homephone IS NULL AND m.homephone = '0') OR (d.homephone = '0' AND m.homephone IS NULL))
AND NOT ((d.workphone IS NULL AND m.workphone = '0') OR (d.workphone = '0' AND m.workphone IS NULL))

I am trying to setup a query that receives input variables one being a number which could be null (could receive as string).

What I want to happen is if a number is sent the data is filtered by that number but if it is empty no filtering is performed I think this involves using a case statement in a where clause but can't work out the syntax I am using sql 200 server.

I think the case statement is something like this:
(week_no = CASE @week WHEN null THEN '#' ELSE @week END)
or maybe I am way off

I considered using like @inNumber + '%' but this would cause the problem of if I inoput 2 it would also return 20's 200's ...

Database Tables And NULL Fields

Nov 17, 2006

Hi  there,
 I have a fairly generic question regarding database design.
I am working  on my first database using SQL  Express.
I am testing the database by inserting records into the pre  defined tables.
Sometimes I  forget to input text into a non null  field. When
this  happens  it displays an error  and then skips a  few rows
which makes my  row numbering  messy.  For example  say I have 
Row  1, Row 2 Row  3 all  nicely  formatted but on Row 4  I make  a mistake
this  row then disapears and  their is  gap  between  3 and 5 where  4  was.
Although I am just testing, I was  wondering  what happens in a  real
scenario if an inexperienced data input person makes a few  mistakes it
makes the database  numbering  systems look bad. In  this case
is it common  to  make  most  fields  NULL to allow for admin errors??

Setting Duplicate Fields To NULL

Mar 19, 2008



I have a result set stored in a temporary table variable. The fields need to have heirarchy when they finaly get displayed to the user. I need to replace the repeating fields per group with NULL and leave out only one set of unique records per group.

I want to do something like this- make the fields in red NULL while leaving out the ones in green.

{ Col.Group I } { Col. Group II }

Col1 Col2 Col3 Col4 Col5
------- ------- ------- ------- -------
ValA ValA2 ValA3 ValA40 ValA50 {
ValA ValA2 ValA3 ValA40 ValA50 Row. Group A
ValA ValA2 ValA3 ValA41 ValA51 }

ValB ValB2 ValB3 ValB40 ValA50 { Row. Group B
ValB ValB2 ValB3 ValB41 ValA51 }



I was able to achieve this by using @@ROWCOUNT with in a while loop by performing one UPDATE at a time (SET ROWCOUNT = 1). But i have to run Count(*) each time I loop through the update query to figure out the remaining number of rows I have per group as I need to leave out one untouched. But the Count function is taking too much time and I'm having performace issues.

Any idea how I might be able to do this in my stored proc. efficiently?

Thanks,

Samtadsh
