View 2 Replies View RelatedI have following select-statement:
select [date], [close], AVG([close]) over (order by [date] rows between 2 preceding and current row ) as [ma]
from dax2
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].
How can i achieve that this "erroneous" values are not inserted or rather are shown as null.
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

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
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.
For example @Month = 01 and @Year = 2014 would return a StartDate of 2014-01-01 and an EndDate of 2014-01-31.
In sql server 2000 - our QA pointed out that his testing for empty strings returned 200 + rows but that when he clicked in the field there were obviously a space there. This issue came up because of the script I created to replace and earlier one that queried on empty strings instead of datalength and the earlier script always reported that it had updated x number of rows regardless of how many times it was run on the same database.
QA query based on the earlier script:
Select * from StringTable
WHERE (LongString = '' OR LongString IS NULL)
My script:
The fields are nvarchars in the newer database but older version of the database had varchars. I had created a script to replace empty strings as follows:
-- if LongString column is varchar - run varchar update else nvarchar update
If exists (Select * from sysobjects o
inner join syscolumns c on c.id = o.id
where c.name = 'LongString' and o.name = 'StringTable' and c.xtype = 167) begin
-- update varchar LongString
UPDATE StringTable
SET LongString = char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(LongString ) < 1) OR LongString IS NULL)
END
Else Begin
-- update nvarchar LongString
UPDATE StringTable
SET LongString = char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(LongString ) < 2) OR LongString IS NULL)
END
If exists (Select * from sysobjects o
inner join syscolumns c on c.id = o.id
where c.name = 'ShortString' and o.name = 'StringTable' and c.xtype = 167) begin
UPDATE StringTable
SET ShortString= char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(ShortString) < 1) OR ShortString IS NULL)
END
Else Begin
-- update nvarchar ShortString
UPDATE StringTable
SET ShortString= char(32)
-- Select * from StringTable
WHERE ((DATALENGTH(ShortString) < 2) OR ShortString IS NULL)
END
My method for checking for datalength appears to work correctly why doesn't the QA script? I thought it might have to do with the nvarchar used in the table but I changed the column to a varchar and still has the same issue.
Thanks
Writing a SQL Function as below
the input parameter for function should be datetime of sql datetimeformat
and out put should be a string = yyyymmdd1 or yyyymmdd2
The last character 1 or 2 based on below condition
if time is between 6AM and 5.59PM then 1
if 6PM to 5.59AM then 2
What i need is to create a function that compares 2 strings variables and if those 2 variables doesn't have at least 3 different characters then return failure , else return success.
View 9 Replies View RelatedWe 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 a User Defined Function in my SQL Server 2000 database which takes a string and adds an integer quantity to it. The function basically takes the string (string because of first character and spaces) and adds an integer to it creating a new number (starting number and ending number concept).If I pass in a string that has a letter for the first character, it works fine. However, if the first character is an integer it trims out all 0s and whitespace and ruins the necessary formatting. Note, the formatting is always the same - x xxx xxxx xx. Any help or ideas would be appreciated.Example:D 499 8900 01 plus a Quantity of 10 returns D 499 89000 11 which is perfect.However,0 076 0000 03 plus a Quantity of 1 returns 764 764 (it should be 0 076 0000 04)------------------------------------CREATE FUNCTION [dbo].[NEW_End_NR2]( @OldStr as char(20), @Quantity int )RETURNS @NewNR_Tbl TABLE (New_EndNr char(20) primary key)AS BEGIN DECLARE @NewStr char(20) DECLARE @addNr integerBEGIN Set @addNr = @Quantity set @NewStr = (select REPLACE(@OldStr,left(@OldStr, 1),'')) set @NewStr = (select REPLACE(@NewStr,' ', '')) + @addNr set @NewStr = (SELECT left(@OldStr, 1) + SPACE(1) + left(@NewStr,3) + SPACE(1) + left(REPLACE(@NewStr, left(@NewStr,3), ''), 4) + SPACE(1) + left(REPLACE(@NewStr, left(@NewStr,7), ''), 3)) BEGIN INSERT INTO @NewNR_Tbl (New_EndNr) VALUES(@NewStr) END END RETURNEND

This 'problem' has occured many times, but I've always found a way around it.
I have pages with datagrids, in which a user can edit a certain fields and then update the tables with new data. Lets say when a user edit a Name field and a money field. If he/she left those two fields blank, the table is automatically updated with a <null> (for the name field) and a 0 (for the money field.) Both these columns were set up to allow Null values.
Anyone has an idea why they were updated that way? And is there like a standard on how the data types are updated if a field is left blank?
Thank you very much.
Hi!
Is there any fucntion avaible in SQL for search a character position in a string.
e.g. 'ABC-DEF'
- is located at the position of 4
I tried the charIndex, Is it same as Instr in ORACLE. Is there any INSTR function available
does anyone know a function to count the number of times a substring appears in a string?
example NumberOfTimes("i","mississippi") would return 4
I need to take the character from a text field. I need the character which
is the second one from the end(right). Like out of '12345' or '99821'
I would need the 4 from the first and the 2 from the second. Can I combine
a string and a right statement to do this?
Thanks
Here is the scenario.
I have a 10 position varchar field that holds a project number. The project number is in the form yy-nnn... where yy is the current year (06) and nnn is a sequential number. The project number is displayed on a data entry form so that the next record has the next sequential number.
So when the data entry form first opens the project number field has 06-1 after that record is entered the form is cleared and reinitialized and the project number now shows 06-2. If the form is closed and then reopened the project number would still show 06-2 if that previous record was not entered and 06-3 if it was.
The way I am going about getting the next sequential number is the following:
SELECT MAX(RIGHT(ERFNumber, LEN(ERFNumber)-3)) AS MaxERFNumber From Table1
This approach is working fantastic until record 06-9 is entered. The above line does determine that 06-9 is the MAX record and then creates a record 06-10 but every subsequent time a record is attempted it still thinks 06-9 is the MAX value of the above statement.
I am assuming that since the field is defined as a varchar the MAX function is applying character logic versus numeric logic thus the 9 being treated as the MAX value.
Is there an SQL function that can change the result of RIGHT(ERFNumber, LEN(ERFNumber)-3) to a numeric value so that the MAX function will work correctly.
I know there are many other ways to do this but in the interest of time because the application is almost finished, changing this now is going to be a major undertaking.
Any help or guidence would be greatly appreciated.
Hi all, iam trying to find a string function which would replace column value where there is a ssn with 1 and anything else(blank,null,...) with 0. i need to count the number of rows with ssn and one without ssn.

hi kristen or anybody there,
is there a way you can concat string columns in a select statement... i have two tables (joined) and i wanted to display a concatenated values.
data details:
table 1
pk_transactionid transactiondate and so on
1 1/1/2007 *********
2 1/2/2007 *********
3 1/3/2007 *********
table 2
pk_rowid fk_transactionid description
1 1 record1
2 2 record2
3 3 record3
4 1 record4
5 2 record5
6 1 record6
result set should be like this
pk_transactionid transactiondate description --> this is concatenated
1 1/1/2007 record1, record4, record6
2 1/2/2007 record2, record5
3 1/3/2007 record 6

I have a table with a column called Userdef. I is a user defined field. It looks like this ;;Polk;D-0002;;;;As you can see it is delimited by semicolons. I need to separate the semicolons into separate files like this Field1Field2Field2Field4Field5Field6<null><null>Polk<null>D-0002<null>How do I write this query in SQL Server?
View 1 Replies View RelatedThis function is useful for fixed width output. E.g.
String(expr,10-len(expr),'0') will give you a number with leading zeros so it is always 10 characters long.

Hello All,
I have am importing a file that contains an address field where the city and state are in the same field, IE ['Atlanta, GA']. How do I separate the city and state into separate fields. I can get the state by using the RIGHT function. My problem is getting the city information up to the comma.

In VB there is InStr, in Excel you have SEARCH. what function can i use to search a string for a specific string. ie: how can i find where a space is in someones name?
our database has a table that is used for security. it contains a user code, user name and passcode. i need to split the username (currently forename and surname in same field) into two, around the space.
in VB i would write something like
strFName = left(<usernamefield>,InStr(1,<usernamefield>," ")-1)
to get the forename and similar to get the surname. how can i do this in SQL so that a view will supply the data apprpriately?
one of the reasons i want to do this is so that i can sort the users by surname! another is so that i can give options on their usercode - a combination of forename initial and 2 characters from surname.
any help welcomed.
The 'LIKE' function looks for words that start with whatever is in the like condition. Is there an sql function similar but will look and compare at any part of the search string.
For example I am using a webservice in dot net to populate a dropdown list using this sql
SELECT compound_name FROM dbo.compound_name WHERE compound_name like @prefixText
In this table there is a compound called SILCAP310 and I would like the search function to pick up 310 if I put this into the @prefix parameter. (but I would still like the search to perform like the 'LIKE' does also.
SELECT compound_name FROM dbo.compound_name WHERE compound_name like @prefixText or compound_name SearchPartString @prefixText
Thanks in advance
select left('Hello World /Ok',charindex('/','Hello World /Ok')-1)Hello WorldThat works fine.However I got an error message:select left('Hello World Ok',charindex('/','Hello World Ok')-1)Instead of:'Hello World Ok'I get:Server: Msg 536, Level 16, State 3, Line 1Invalid length parameter passed to the substring function.Microsoft Doc incorrectly says:"LEFT ( character_expression , integer_expression )integer_expressionIs a positive whole number. If integer_expression is negative, a nullstring is returned."Is there an easier solutoin using left or any other string functioninstead of using a case statement?Also, charindex('/','Hello World Ok') should return NULL instead 0 sothat we can use isnull function.Thanks.
