How is the best way to make a function for summing an arbitrary number of times values (table parm?)- I 've read it's necessary to convert to seconds, sum then convert back, but Im' wondering if there's an alternative.
Here's the example I want to sum:
00:02:01:30
00:01:28:10
00:01:01:50
00:06:50:30
00:00:01:50
I have a table with duration values for different machine states. I 'm trying have a sum of the duration value of each state ( the duration sum , was an earlier question).
declare
@tblDurations
TABLE
(StateName
nvarchar(30),Duration
nvarchar(30))
[code]...
I want the output to have sum of the duration ( from my function ), grouped by the state.So output should be :
Breaks 00:02:03:40
Meetings 00:00:01:50
Running 15:21:07:16
I think this can be done with windows functions, but how I don't know.
I have a column with XML data stored in it. I need to update that column several times with new values for different nodes. I've written a CLR function to update the XML quickly but the update is always based on the initial value of the xmlData column. I was hoping that the subsequent updates would be based on the new data from the prior update (each xmlTable has several newData rows). Do I have to make this a table valued function and use cross apply?
UPDATE xmlTable
SET xmlTable.xmlData = Underwriting.UpdateByDynamicValue(xmlTable.xmlData,newData.NodeID,newData.NewValue)
FROM xmlTable
JOIN newData
ON xmlTable.ID = newData.fkXmlTableID
I am learning the string functions and the database that I'm using is AdventureWorks2012.However ,while practicing I was just trying to hide the phone number with '*' mark,but not getting the desired result.So the code is.............
SELECT

SUBSTRING(PhoneNumber,CHARINDEX('[0-9][0-9]{1,2}',PhoneNumber),LEN('-555-01')))AS[PhoneNumber]

Below is the stored procedure i have it works fine if i have 1 value passed to @invited_by but i want to modify but i want this code to be working for multiple inputs .Lets say if i do

exec [dbo].[sp_GetInvitationStatusTest] 'Test1,Test2'.

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
is it possible to use the window functions to count the number of rows in the previous 24hours from the current row.
I have a table of events like:
User, TimeStamp, etc...
I want to identify the row which is the event number 50 in the past 24 hours.
does the window functions can do this? and how?
the ROW PRECEDING etc... appear to not have enough feature to support time related function.
Stream-insight is able to create this type of query, but I have to do it directly in SQL.
I have two tables (i.e. Table1 and Table2).
SELECT
* FROM [dbo].[Table1]
Date
id
9/15/2015
[code]...
Table2 has three columns (i.e. Date, Count and Rule Type). Column “Rule Type “has a default value which is “XYZ”..Now I want to insert Data from Table1 to Table2. I am using following query:-
declare @Startdate
datetime
DEclare @enddate
datetime
[code]...
Column name or number of supplied values does not match table definition.I am using SQL 2012. I understand Table1 has 2 Columns but Table2 has 3 Columns. Is there anyway, I can move data from source table to Destination table where Destination Table has more number of Columns?
I've to write a function to return a comma delimited values from a table columns
If a table has Tab1 ( Col1,Col2,Col3).
E.g. as below ( the columnName content I want to use as columns for my pivot table
CREATE FUNCTION [RPT].[GetListOfCol]
(
@vCat NVARCHAR(4000)
)
RETURNS @PList
AS
BEGIN
SELECT @PList += N', [' + [ColumnName] +']'
FROM [ETL].[TableDef]
WHERE [IsActive] = 1
AND [Category] = @vCat
RETURN;
END;
I want out put to be as below, I am getting this output from the select query independently by declaring @Plist variable and passing @vcat value, now I want it to be returned from a function when called from a select query output ,Colum1,column2,....
I'm running the following test query on a single table:
SELECT sph.datestamp, sph.stocksymbol, sph.closing, DATENAME(dw, sph.datestamp),
CASE DATENAME(dw, sph.datestamp)
WHEN 'Monday' then 'Monday'
ELSE (SELECT CAST(sph2.datestamp AS nvarchar) FROM BI_Test.dbo.StockDB AS sph2 WHERE sph2.DateStamp = DATEADD(d, -1, sph.datestamp) AND sph2.StockSymbol = 'NYA')
END AS TestCase,
[Code] ....
And here's an example of the output I'm getting:
Why the exact same subquery in the THEN of the second CASE statement is returning NULL when the first one completes as expected?
I have two tables, D and C, whose INTERSECT / EXCEPT values I'd like to insert in the following table I've created
CREATE TABLE DinCMatch (
servername varchar(50),
account_name varchar (50),
date_checked datetime DEFAULT getdate()
)
The following stmt won't work...
INSERT INTO DinCMatch
select servername, account_name from D
intersect
select servername, account_name from C
... as the number of supplied values does not match table definition.
Hello,
Here's one way to sum only the top 5 (greatest 5) values per group.
I assume there is a table called IdValues that contains two columns: id int, value int.
declare @lastId int
declare @value int
declare @count int
declare @idList varchar(5000)
declare @valuelist varchar(5000)
set @count=0
set @lastId = -1
set @value = 0
set @idList=''
set @valuelist=''
select
@count=(case when @lastId<>id then 1 else @count+1 end),
@value=(case when @lastId<>id then value when @count<=5 then @value+value else @value end),
@idList=(case when @lastId<>id then cast(id as varchar)+','+@idList else @idList end),
@valuelist=(case when @lastId<>id then cast(@value as varchar)+','+@valuelist else cast(@value as varchar)+','+right(@valuelist,len(@valuelist)-charindex(',',@valuelist)) end),
@lastId=id
from IdValues
order by id desc, value desc
select @idList,@valuelist
It's a funny approach. I'd be interested to see a better method. In MySQL it is possible to do this much better and have it produce an actual resultset (since MySQL allows you to assign variables and product a resultset in the same query).
I also noticed something interesting. If you do any operation on the order-by columns, the query doesn't work. For example, if I do:
order by id+0 desc, value desc
something funny happens and you only get one id and one value in the list variables. Maybe someone else who actually some idea of how SQL Server works can explain this.
Thanks,
Thomas
I have tables and a function as representated by the code below. The names for objects here are just for representation and not the actual names of objects. Table RDTEST may have one or multiple values for RD for each PID. So the function GIVERD will return one or multiple values of RD for each value of PID passed to it.
When I run the following query, I get the required result except the rows for CID 500 for which PID is NULL in table T1. I want the rows for CID 500 as well with PID values as NULL.
SELECT A.CID,
A.ANI,
A.PID,
B.RD
FROM T1 AS A CROSS APPLY GIVERD(A.PID) B
CREATE TABLE [DBO].[RDTEST](
[PID] [INT] NULL,
[RD] [INT] NULL
)
[Code] ....
hello,
I have the following and what to do SUM the valueS in each in another textbox, what is the proper method?
=count(Fields!Month_Submitted.Value, "SALES")
=count(Fields!Month_Submitted_1.Value, "SALESDIR")
=count(Fields!Month_Submitted_2.Value, "SALESVP")
=count(Fields!Month_Submitted_3.Value, "CREDIT")

In SQL server Reporting service we need to export excel formula for summing column values. scenario : After generating report we are exporting report to excel file using report viewer.when user will modify a column value we need to calculate(update) automatically sum of the column values.Basically we are setting excel formula.

I have both positive and negative values in a single column, where I want sum total of positive values & negative values. Is there any Expression for this to sort out.
Hello Everyone
I've created a report with a simple dataset that is similar to this
City , RequestID, Request Amount, ClaimID, ClaimAmount
El Monte 791 52,982.00 2157 41,143.75
El Monte 3691 11,838.00 3140 8,231.14
El Monte 3691 11,838.00 3141 990.00
El Monte 3691 11,838.00 3142 2,615.00
So I group by City, RequestID. On the first group I specified the expression to be City and in the header I list the city and in the footer I list the sum of Request amount. On the second group I specified the group by Request so in the header I placed requestID and on the footer I placed Request Amount. I set request information to hide the duplicates and I even add =Sum(Fields!RequestApprovedGrandTotal.Value,"GroupByRequestID") the scope of the group. But this is what I get:
For requestID = 3691 for Request Amount is 35,514.00 not 11,838.00. All the claim sums are correct and they are located on the detail row.
I've read that a work around is to create multiple dataset but I honestly believe that something as simple as this should work on the reporting server 2000. So I've come to the conclusion that I must be doing something wrong. Can someone give me a hand on this. Thanks.
I need to write a SQL to find number of hours between a begin time and end time. The fields are varchar. There are several date functions in sql, but I am not able to figure out how to get the hours between two times that is not in date format.
BEGIN_TIME END_TIME
0900----- 1500
1000----- 1700
1000----- 1230
0930----- 1030
Is there a way to get the number of occurances of a word within a specific row?
I want to query a dataset and have a column act as the number of occurances of a word within that row. I also need to use Full-Text searching... Is this possible?
Hello,
I see the following problem regarding a SQL function that returns a value.
We have the following query
SELECT c.Id_Customer, c.Name
FROM t_Customers c
WHERE c.Id_Status = fn_GetParameter('ID_Status.Active')
The idea is not hardcoding the status and other values on each query, and, since SQL Server does not support the definition of constants, we have a table with many parameters and we search them.
We defined the function "WITH SCHEMABINDING" and the SQL Server recognizes it as DETERMINISTIC, so I do not understand why it executes the function as many times as records in the t_Customers table, since every time it is executed it returns the same value.
We could define a variable, assign the value returned by this function to this variable and then use it on the SELECT, but this approach is useless if we use SQL instead of stored procedures (for example, in reports from reporting / BI tools).
Any explanation about why SQL chooses to execute the function many times, and any hint regarding how to make SQL Server execute only once the function will be very appreciated.
Thanks in advance,
Lisandro.
Hi all,
In order to return a table for a specific input parameter, I am using Function, but the performance is just awful! After I have tried same code as SP, the whole thing is running under 1 sec (like 0.5 sec), while the function is about 10 times slow (4-6 sec). I know in SQL 2000 function is slower than SP, but that cannot be as bad as 10 times slower.
Now, in order to use that table from SP, I have to create a temp table, then insert result into that temp table, before I can direct use any "select" sentence. Any explanation here? Or how to "select" from a SP directly?
Thanks,
Ning
What i want to do is count how many times the [Omnipay_Account] column is populated with a number per parentid.
In the [Omnipay_Account] column you can either have a null or a 15 digit number
Idea result layout would be three columns these columns would be
Every row, would need to be grouped via the parentid number
ParentId Omnipay MSIP
My query is
SELECT
[ParentID]
,[Omnipay_Account]
FROM [FDMS].[dbo].[Dim_Outlet]
I have a table with about 10 million rows, its been logging data incorrectly and I want to start again.
DELETE FROM tblLog

I got this ERD and I have 2 questions about it:
What is the minimum number of times that R2 can appear in the connection? and what is the maximum?
A=5
B=5
C1=1
C2=2
Some logic for calculating the count for changed values.
E.g. :--
ID VAL
1 10
1 20
1 20
1 20
1 10
1 10
1 10
1 20
1 10
Here in the above table my value changed from 10 to 20 and so.., so Val column value changed 4 times, so I need the result like :
id count
1 4
create proc dbo.usp_CatchAddressException @tableName varchar(500) as
-- alter proc dbo.usp_CatchAddressException @tableName varchar(500) as
begin
set nocount on
declare @sql varchar(700)
-- truncate table tempException
set @sql = 'insert hava_dcde.dbo.STREET_EXCEPTION (id_town, id_voter, pre_value, nbr_exception, date_stamp)
select a.id_town, a.id_voter, substring(a.ad_str1, 1, len(a.ad_str1) - charindex('' '', reverse(a.ad_str1))), ''20'', getdate()
from HAVA_DCDE.dbo.' + quoteName(@tableName)+ ' a
where substring(a.ad_str1, 1, len(a.ad_str1) - charindex('' '', reverse(a.ad_str1))+1) not in
(select nm_street from HAVA_DCDE.dbo.state_streets ss)'
-- and a.id_town = + @tableName
-- print(@sql)
exec(@sql)
set nocount off
end

when i run this SP 2 times, it will insert the values 2 times.
what should i do if i don't want to insert the same values 2 times?
I'm confussed, Should i use update? any input will be appreciated.
I am trying to update the same row of the table multiple times. in other words, i am trying to replace the two stings on same row with two different values.
Example: if the column has a string "b" then replace with "B" and if the column has a string "d" then replace with "D" . I can write multiple updates to update it but i was just wondering if it can be done with single UPDATE statement
column before the update : bcdxyz
after the update: BcDxyz
Following is the sample data
declare @t1 table
(
c1 varchar(5),
c2 varchar(10),
c3 varchar(5)
)
insert into @t1 values ('a','bcdxyz','efg')
[Code] ....
I have created approximately 200lines of multiline table function. getting table variable values as what I need satisfying all our business rules.
my question : is it okay in performance wise using loop i executed this function 100000 times and it took around 16mins.
In my staging table I am having data like below
ABL¯ABL¯0¯0¯ABL¯ ¯ ¯ ¯ ¯ ¯ ¯ ¯ ¯
ABL¯ABQ¯480¯825¯DLS¯AMA¯ABQ¯ ¯ ¯ ¯ ¯ ¯ ¯

What is a more efficient way of doing the following such that DATEDIFF() does not have to calculated numerous times?
CASE
WHEN DATEDIFF(DD, @Today, COALESCE(POS.[PurchaseDate], POS.[FinalizedDate])) <= 0 THEN '<= 0D'
WHEN DATEDIFF(DD, @Today, COALESCE(POS.[PurchaseDate], POS.[FinalizedDate])) > 0 AND DATEDIFF(DD, @Today, COALESCE(POS.[PurchaseDate], POS.[FinalizedDate])) <= 7 THEN '> 0D AND <= 7D'
WHEN DATEDIFF(DD, @Today, COALESCE(POS.[PurchaseDate], POS.[FinalizedDate])) > 7 AND DATEDIFF(DD, @Today, COALESCE(POS.[PurchaseDate], POS.[FinalizedDate])) <= 30 THEN '> 7D AND <= 30D'

I am doing some analysis on shifts and what I want to do is say if the time from a timestamp field is between 00:00 and 05:59 then the figures belong to the day before. Eg. We have a night shift that work 22:00 - 06:00.
Here is my coding which logically looks sound to me but when I run it, it has an error:
SELECTe.ID,
CAST(e.TimestampasDate)asEventDate,
CAST(e.TimestampasTime)asEventTime,
CASE
WHENCAST(e.TimestampasTime)BETWEEN'00:00:01'and'05:59:59'
THENCAST(e.TimestampasDate)-1
ELSECAST(e.TimestampasDate)
