Trying To Call A Function On A Weekly Timer
Sep 17, 2007
I'm not sure this is the place for this question, but not sure where else to go.
I've written asp.net code to read from a sql server 2005 db and send out customized emails based on user info.
Currently the process gets rolling by clicking a button in a web page.
The client doesn't want to click a button, they want to run the email sender on a timer.
How can I set up my function to run on a timer either in asp.net or more likely called from sql server?

Hi Remus,
I just started looking into SB about a week ago, so my question is likely to be pretty lame. However, that's not going to stop me from asking it :-)
We're trying to do something similar to what you're describing here. How do you "reset" a dialog timer? Why would you need to deal with resetting timers (or with timers at all for that matter) in the event of a success? Couldn't you rewrite the logic to be as follows?
begin transaction
receive message
if message is web request
save state of request (http address, caller etc)
else if message is retry timer message
load state of request
endif
commit
do the web request (no transaction open)
if success
begin transaction
send back response
end conversation
commit
else
set a retry timer on the dialog (say 1 minute) using BEGIN DIALOG TIMER
endif
Also, when you set the retry timer you have to associate it with the saved request state, right? Otherwise, how will the service know which request to load on receipt of the timer message?
TIA.

I have a query that will generate records monthly based on the number of months that i calculate between two date feilds for a given requestid. How can i use the same query to generate records for weekly and bi weekly based on the receiveddate field that i use in the subtraction for calculating the number of months.
Also when inserting i have been adding a month for every record as i was generating monthly and now i would have to add week and 2 weeks to the receiveddate
SET NOCOUNT ON
GO
declare @num_of_times int
declare @count int
declare @frequency varchar(10)
declare @num_of_times1 int

I want to write function to call another function which name isparameter to first function. Other parameters should be passed tocalled function.If I call it function('f1',10) it should call f1(10). If I call itfunction('f2',5) it should call f2(5).So far i tried something likeCREATE FUNCTION [dbo].[func] (@f varchar(50),@m money)RETURNS varchar(50) ASBEGINreturn(select 'dbo.'+@f+'('+convert(varchar(50),@m)+')')ENDWhen I call it select dbo.formuła('f_test',1000) it returns'select f_test(1000)', but not value of f_test(1000).What's wrong?Mariusz

Can someone help me to understand a stored procedure I am learning about? At line 12 below, the code is calling a function named"ttg_sfGroupsByPartyId" I ran the function manually and it returns several rows/records from the query. So I am wondering? does a call to the function return a temporary table? And if so, is the temporary table named PartyId? If so, the logic seems strange to me because earlier they are using the name PartyId as a variable name that is passed in.
1 ALTER PROCEDURE [dbo].[GetPortalSettings]2 (3 @PartyId uniqueidentifier,45 AS6 SET NOCOUNT ON7 CREATE TABLE #Groups8 (PartyId uniqueidentifier)910 /* Cache list of groups user belongs in */11 INSERT INTO #Groups (PartyId)12 SELECT PartyId FROM ttg_sfGroupsByPartyId(@PartyId)

I made an SQL function in MSSQL2000. This is a function that get's a calculated heat emission. When I run the Query in MSSQL2000 the function works. It calculates every emission for every row. When I call this SQL function in VS2005, it says it does not recognize the function. Does anyone know what this may cause? thank you. For the people who are bored, I added the SQL statement. The error is at the function
SELECT TOP 15 tbProducts.prod_code, tbProductProperties.prop_height, tbProductProperties.prop_length, tbProductProperties.prop_type, tbProductProperties.prop_default_emission, tbProductProperties.prop_weight, tbProductProperties.prop_water_volume, tbProductProperties.prop_n_value, GetHeatEmission(50,70,20,[prop_default_emission],[prop_n_value]) AS customEmission FROM tbProductClassification INNER JOIN tbProducts ON tbProductClassification.clprod_fk_prod_id = tbProducts.prod_id INNER JOIN tbProductProperties ON tbProducts.prod_id = tbProductProperties.prop_fk_prod_id WHERE (tbProductClassification.clprod_fk_class_id = 3327) AND (prop_height >= '030') AND (prop_height = '060') AND (prop_length

I have a procedure which has query
like Query 1.
Query 1
Select Clinetid
from clinet
inner join {
select centerid from GetChildCenter(@Centerid)
union
select centerid from getParentCenter(@Centerid)
} as Center c
on c.Centerid = client.Centerid
Query 2
declare @Center table ( centerid int)
insert into @Center
select centerid from getchildCenter(@Centerid) union all select centerid from getparentcenter(@Centerid)
Select Clinetid
from clinet
inner join @Center c on c.Centerid = client.Centerid
I just want to know which one is better performance wise..
because there is millions of rows for table center which is used by function getChildCenter() and GetparentCenter()

Hi All,
I'll admit that I'm not the greatest at stored procedure/functions but I want to learn as much as possible. So I have two questions:
1) I had VS2005 autogenerate a sqldatasource that created Select/Insert/Update stored procedures. When Updating a record and calling the stored procedure, I want to query another table (we'll call it tblBatchNo) that has only one record, Batchno. I want to put that current batchno into the Update statement and update the record with the current batchno. Can someone point me in the right direction? Remember that I'm still a beginner on this subject.
2) Can someone provide any links to online tutorials on t-sql?
Thanks in advance.

Hello Guys,
I have a question that seems easy but I can not figure out...
Premise:
Have Custom code that fixes Divide by Zero Errors in SSRS. I have added the code to the Custom Code area in Report Properties correctly.
I have a Dataset that has a calculation for a column within a select statement
Query Pseudocode:
select ...[FRC%]=convert(decimal(13,2),sum(cost))/convert(decimal(13,2),sum(income))...
,year
from
(subquery"blah" )
Union
(Subquery"blah")
Custom Code:
Public Function SafeDiv(ByVal numerator as Double, ByVal denominator as Double) as Double
if denominator = 0 then
return 0
else
return numerator/denominator
end if
End Function
How To use:
If you have a field that does division and you need to eliminate the divide by zero error that occurs with SSRS then type =code.SafeDiv(first,second) in the field.
Problem:
How do I add this code reference in the following dataset select statement
select ...[FRC%]=convert(decimal(13,2),sum(cost))/convert(decimal(13,2),sum(income))...
,year
from
(subquery"blah" )
Union
(Subquery"blah") table1
I tried to do this:
from this:
[FRC%]=convert(decimal(13,2),sum(cost))/convert(decimal(13,2),sum(income)) ...
to this
[FRC%]=code.Safediv(convert(decimal(13,2),sum(cost)),convert(decimal(13,2),sum(income))) ...
But it did not work...gave me this error:
TITLE: Microsoft Report Designer
------------------------------
An error occurred while executing the query.
Cannot find either column "code" or the user-defined function or aggregate "code.safediv", or the name is ambiguous.

ADDITIONAL INFORMATION:

Help!
P.S.
this is a Matrix report and this select statement is within one of the datasets that fill a matrix.

I have a function that I need to call from an execute sql task. I want to bind the return value from the function to an ssis variable.
Can someone please show me an example of what the function syntax needs to look like in order for this to work? I know that with sp's, you need to explicitly state the column names.
I have tried many things without success.

Good day!
What is the syntax on calling a function from a column formula in an MS SQL table.
I created a table, one column's value will be coming from a function. And at the same time, I will pass parameters to the function. How do I do this? Is this correct?
SELECT dbo.FunctionName([Parameter1, Parameter2])
But i can't save the table, "Error validating the formula".
Pls. help
Thanks a lot.

Hello Folks,I encountered a problem with SQL server 2000 and UDFs.I have a scalar UDF and a table UDF where I would like the scalar UDFto provide the argument for the table UDF like in:SELECT*FROMtransaction_tWHEREtrxn_gu_id in (select get_trxns_for_quarter(get_current_quarter( GetDate() ) ))'get_current_quarter' returns an integer which is a GUID in a tablecontaining business quarter definitions, like start date, end date.'get_current_quarter' is a scalar UDF.'get_trxns_for_quarter' will then get all transctions that fall intothat quarter and return their GUID's in a table.'get_trxns_for_quarter' is a table UDF.This doesn't seem to work at all. Regardless whether I provide thenamespace (schema) calling the scalar UDF or not. Error message isjust different.Both functions operate correctly invoked un-nested.The whole expression does work fine if I turn 'get_trxns_for_quarter'into a scalar UDF as well, e.g. by returning just one trxn_gu_id withe.g. MAX() in a scalar datatype. But of course that's no good to me.It also works fine if I select the result of 'get_current_quarter'into a variable and pass that variable into 'get_trxns_for_quarter'.But that's no good to me either since then I cannot use the wholething embedded into other SELECT clauses.Both UDF's are non-deterministic but I couldnt see how that would havean impact anyway.Never mind the syntax on that example or anyhting, I tried all theobvious and not so obvious stuff and it really seems to come down tothe fact that one UDF is scalar and the other one is not. However, Idid not come across any type of information saying that this cannot bedone.Have you any ideas?Any help would be greatly appreciated.Carsten

All,
I have to use a field that is calculated in a data flow process and call a database function (return a value) to do anther calculation; then return a value back to the data flow. I tried OLD DB Command but I cannot configure to return a value back to the same data flow.
If there any transformations that can call a DB function and get a value from the function in the middle of the data flow process? Need more detailed instruction.
The data flow is Like:
SourceDB Ã New_filed 1 = field1 + filed2 Ã New_filed 2= DB_function (New_filed 1) Ã Destination DB
Thanks in Advance

HI,

CREATE OR REPLACE function GET_ZONEID_FROM_SYFZ(ycz varchar2,xc varchar2,strat_id varchar2)
return varchar2 IS
zone_id_result varchar2(10) ;
begin
PKG_DM_DQ.GET_ZONEID_FROM_SYFZ(ycz,xc,strat_id,zone_id_result);
return zone_id_result;
end;
In OLEDB command transformation component, i fill the sql command with "select GET_ZONEID_FROM_SYFZ(?,?,?) from dual", but i dont have it worked.
The error message is :provider can not derive parameter information and setparameterinfo has not been called.
Who have any idea about how to make it work?

Hi,
I just found out that when I create a user defined scalar function, I must call it using dbo.[myFunctionName]. Why won't it work w/out dbo? Why are stored procedures able to use omit dbo?
Also, what is dbo specifying? I'm very unfamiliar with sql server security. Is this the user, schema, role? What's a schema? lol. Thanks.

I have a Progress DB set up as a linked server.
To get the data through to SQL Server 2005 in a useable format i need to use the progress PRO_ELEMENT function call. How do I delimit this so it gets passed to the progress DB.
I've tried
SELECT
{fn PRO_ELEMENT(fldarr1,1,1)} as fld1
from ls1..pub.tab
This just returns an unknown function message which I believe is on the SQL Server end of the call.
This statement works fine through Business Objects.
Any help greatfully received.

Hi,
In a nut shell I want to be able to instruction some Data Analysts on how to modify SSIS packages using the simpliest solutions possible. This is because there are many different data sources and some of these data sources have a huge number of fields, and yes you guessed it these data sources are subject to change on a regular basis.
A very common task they will need to do is to modify an SSIS package to do a to transform of a source date string format of "YYYYMMDD" into a date data type field within a table.
Similar threads have advised the use of the Data Flow Transformations->Derived Column for this sort of thing.
So within the Expression Text box I have inserted the following SSIS compatible SQL to convert the above string into a british format date data type; -
Code Snippet
(SUBSTRING(DOB_SRC,8,2) + "/" + SUBSTRING(DOB_SRC,5,2) + "/" + SUBSTRING(DOB_SRC,1,4))
But really what I want to be able to do is to instruct the Data Analysts to do is something like; -
ConvertTextToDate(DOB_SRC)
Where I previously defined that behaviour of ConvertTextToDate as a public VB.NET function.
Can someone please help. I'm pretty certain I'm not the only one with this type of requirement.
Thanks in advance,
Kieran.
