Is there a function that compares two columns in a row and will return
the highest of the two values? Something like:
Acct Total_Dollars Collected Total_Dollars_Due
11233 900.00 1000.00
Declare @Value as money
set @Value=GetHighest(Total_Dollars_Collected,TotalDol lars_Due)
Print @Value
This function will return 1000.00 or the Total_dollars_Due??
Is there such a creature???
I have four columns that include numbers like: A B C D
I want to update D with highest value of A, B or C.
For example A = 1, B = 2, C= 3 then D should be 3.
Can you help me?
From the table i want everything highlighted with a *I wanted an SQl expression to look at values in Column 1 (ID), look atthe corresponding values in the second column (F1) and select the rowwith the highest value, and then if there was more than one row forthat ID with the same value in F1, look at column 3 (F2) and selectthe row with the highest value in this column.SQL> select * from test;ID F1 F2---------- ---------- ----------1 12 4* 1 12 61 11 11 9 122 3 5* 2 9 132 9 93 1 23 1 1* 3 7 5I try the followingSQL> select * from test t12 where f1 = (select max(f1) from test t2 where t2.id = t1.id)3 ;And get the followingID F1 F2---------- ---------- ----------1 12 4* 1 12 6* 2 9 132 9 9* 3 7 5If I add another line with an AND statement after line 2 I either getnothing or rubbish as the output.Ideas?Cheers

View 3 Replies View RelatedI have following select-statement:

My Problem is that the first 2 rows in column [ma] are not correct. They Show a value since it is not a 3 days average. In the first row in column [ma]is the same value as in [Close]. In the second row in column [ma] is the average value of the first and second value of column [Close].

Hello All,
I have a situation where after creating roles and addding users to the roles then when i call Is_Member('MyRole') on my development box it tells me the user is a member of the Role,
But when i detach the database and deploy on a production server and call Is_Member('MyRole') it tells me that the user is not a member of the Role....
I went on to call the system stored procedures, sp_helprolemember to actualy determine if the user is in the 'MyRole' role and the procedure returned a list which i confirmed that the user actually exists in that role..
So am pretty confused when i call Is_Member('MyRole') and it gives me 0 meaning the user is not in the role....
Plss i need help on this thanks a million
KNOW THY SELF
Dear all hi,
I would like to create a function that will return to me the width of the column of the table without giving as a parameter the table name. I need it, as I want to exceed my data in this column to the column length. I want to fill the column data with trailing blanks until I reach the column width. The function len returns the length of the data in the column.
I know that If I have the table name I can find the column width through the system tables. I don€™t want this.
Sincerely,
Hellen
Hello!
Is there a function that gets the name of a column and a string as arguments and returns the position of this string in the column given?
Thank you in advance.
From what I've seen, the CheckSum_Agg function appears to returns 0 for even number of repeated values. If so, then what is the practical use of this function for implementing an aggregate checksum across a set of values?
For example, the following work as expected; it returns a non-zero checksum across (1) value or across (2) unequal values.
declare @t table ( ID int );
insert into @t ( ID ) values (-7077);
select checksum_agg( ID ) from @t;
-----------
-7077
declare @t table ( ID int );
insert into @t ( ID ) values (-7077), (-8112);
select checksum_agg( ID ) from @t;
-----------
1035
However, the function appears to returns 0 for an even number of repeated values.
declare @t table ( ID int );
insert into @t ( ID ) values (-7077), (-7077);
select checksum_agg( ID ) from @t;
-----------
0
It's not specific to -7077, for example:
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
0
What's curious is that (3) repeated equal values will return a checksum > 0.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
-997777
But a set of (4) repeated equal values will return 0 again.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (-997777), (-997777), (-997777);
select checksum_agg( ID ) from @t;
-----------
0
Finally, a set of (2) uneuqal values repeated twice will return 0 again.
declare @t table ( ID int );
insert into @t ( ID ) values (-997777), (8112), (-997777), (8112);
select checksum_agg( ID ) from @t;
-----------
0
Any UDF that accepts a Month and Year and returns Start Date and End Date.

We have a customer that is running SQL2012 and we are seeing a weird result on a query when we run it on their db. It is based off of a table that has about 30 columns but in this case we only care about 2 of them.
[Number] [varchar](15) NOT NULL
[Person_ID] [varchar](12) NULL
Here is the query we are doing:
Select Number,Person_ID From TableName where LP='ABC123'
The result I get back is the following:
Number:1
Person_ID:13864
The Person_ID should be a result of another table that created that Person_ID but it doesn't exist in that table. So we do not know where that 13864 is coming from. When we open that record through our application it shows Nothing for the Person_ID in that field.
When we do this query on our copy we get back
Number:1
Person_ID:
Which is exactly what we should see as the result.
Could there be a sql server setting that is set on their server that could possibly be given us back 13864 for a NULL value?
We run std 2008 r2. I haven't looked at my friend's function closely yet bur he showed me that when he selects from the function with one column and the same where clause he uses on same func with select *, he gets no data under the column he requested.Â
But when he selects * he gets a single row.
I took a peek and see a bunch of left joins followed by a bunch of outer applies in his func. I suppose (thinking out load) if anything random like the order of rows returned or sql decisions on how query runs can affect his function, that might explain it. Â
I've written sql code which takes a date and finds the Last Day of the Month one year ago. For example, it takes the date '2015-04-17' and returns the date '2014-04-30'. The code works fine in a query. Now I'm trying to turn this into a function. However, when I try to create the function I get the error:
Operand type clash: date is incompatible with int
Why is this error being returned?
Here is my function:
CREATE FUNCTION dbo.zEOM_LY_D(@Input Date)
      RETURNS date
AS
BEGIN;
 DECLARE @Result date;
 SET @Result = convert(DATE, DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,dateadd(m, -11, @Input)+1),0)),101)
   RETURN @Result;
END;

I have the following Table:
ORDER_ID SKUS
12345678 SCINC, SCNRQ, SRPPR
All the values in the 'SKUs' column are combined together, seperated by a comma.
Is there an easy to way "de-pivot" this so that the Order ID gets repeated as follows:
ORDER_ID SKU
12345678 SCINC
12345678 SCNRQ
12345678 SRPPR
Here's some code:
SELECT ORDER_ID, SKU FROM ORDERS
Is it ill-advised to have columns whose values pull from scalar functionsusing other fields in the record as parameters? For example, if I havecreate table a(iID int primary key)create table b(iID int ,iDetail int,CONSTRAINT PK PRIMARY KEY(iID,iDetail),CONSTRAINT FK FOREIGN KEY (iID) REFERENCES a(iID))Let's say in table b I put price information for each detail and in table aI'd like to put a column that sums these prices for the children of eachrecord. Should I make a computed column that references a function usingiID as a parameter? Or would it be better to create a view for this kind ofpurpose?Regards,Tyler

I have two tables that contain product SKUs (12-character strings):
Table 1Product IdSKU...
Table 2ProductVariantIdSKU...
I need to find the MAX (i.e., last used) SKU that exists in either table. I did write two sps, one for each table that I can compare in code and use the larger (latest) one but I am not that facile with JOINS, etc., so I can't figure how how to create a single sp to return the value I am looking for--although I assume this must not only be possible but trivial to more experienced SQLers.
Thanks!

View 1 Replies View RelatedRecently I have come across a requirement where i need to design a table.
There are some columns in table like below with DECIMAL Datatype:
BldgLength
BldgHeight
BldgWeight
Based on my knowledge, i know that values before Floating-Point will not be more than 4 digits.
Now as per MSDN,
Precision => 1 - 9
Storage bytes => 5
so i can create column as:
BldgLengthDECIMAL(6,2) DEFAULT 0
OR
BldgLengthDECIMAL(9,2) DEFAULT 0
Now while reading some articles, i came to know that when we do some kind of operation like SUM Or Avg, on above column then result might be larger than current data type.
So some folks suggested me that i should keep some extra space/digits considering above MATH functions, to avoid an Arithmetic Over Flow error.
So my question is what should be value of DataType for above column ?
How can i subtract two columns:
I have table:
   Â
ID COL 1 COL 2
-------------------------
1 200.00 70.00
2 200.00 30.00
3 200.00 90.00
4 200.00 110.00Col1 - COL2
But to continue for each row and value is reduced by the previously value.
My output should be like as:
ID COL 1 COL 2 [COL3 AS RESULT]
-------------------------
1 200.00 70.00 130
2 200.00 30.00 100
3 200.00 90.00 10
4 200.00 110.00 -100
Consider the following dataset:
COL1 | COL2 | COL3 | COL4
1 | FD | DR. A | Y
2 | FD | DR. A | Y
3 | FD | DR. A | N
4 | FD | DR. A | Y
5 | FD | DR. A | Y
6 | PF | DR. A | Y
7 | FD | DR. B | Y
8 | PF | DR. B | N
Consider the script below:
SELECT
COL2, COL3, COUNT(COL1) AS TOTALS
FROM CASES
GROUP BY COL2, COL3
ORDER BY COL3, COL2
The script above produces the following output:
COL2 | COL3 | TOTALS
FD | DR. A | 5
PF | DR. A | 1
FD | DR. B | 1
PF | DR. B | 1
I need to add one more column to the script that counts records with 'Y' in COL4 for each COL1 category (FD, PF). The final dataset would look like this:
COL2 | COL3 | TOTALS | NEWCOL
FD | DR. A | 5 | 4
PF | DR. A | 1 | 1
FD | DR. B | 1 | 1
PF | DR. B | 1 | 0
I am having a hard time trying to use COUNT() on multiple columns with the GROUP BY restrictions that exist.
Hi all,
I have a scenario which I am not able to figure out how to do it better for quite some time.
Assume I have a few rows of data :
RunningID Date WOid
1234 1/23/2007 23
1236 1/24/2007 23
1239 1/2/2007 24
1222 1/4/2007 23
1321 2/4/2007 22
My objective is to merge all RunningID into a single cell when WOid is the same (this will most probably use a "group by" to get the different WOid out). Maybe some aggregate function that can do it as:
select ReturnConca(RunningID, "#") as RunningID_str, max(Date) as MaxDate, max(WOid) as WO from tableXXX
group by WOid
Results:
RunningID_str MaxDate WO
1234#1236#1222 1/24/2007 23
1239 1/2/2007 24
1321 2/4/2007 22
Any advise would be much appreciated.
Hello,
I am trying to figure out how to use the select maximum command in SQL Server 2005. I have already created a database and I have it populate it with multiple fields and multiple records. I Would like to create a new column or field which contains the maximum value from four of the fields. I have already created a column and I am trying to figure out how to use a command or SQL statement which is entered into the computed equation or formula in the properties for this field/column.
Any help you can provide will be greatly appreciated!

Currently, I am using the SSRS 2005 and try to toggle the report columns similar to Excel's column grouping function. Users can expand "+" / collapse "-" the columns in the render excel report. It works fine when I excute the tabular report in the web yet the toggle function is missing when I render the report to an Excel report. I am not sure the toggle function will only work for the row items or both as the excel report can keep the toggle function for the row items. Please help.
