Converting Some VBA Code To SQL Function
Sep 6, 2006
Hi,
I'm new to this SQL thing, and I need some help with s stored procedure/function.
First, the scenario:
We are a social service agency, and like all such organizations, we have requirements for perodic reports about our clients. There are lots of them, but if I figure how to do one, I think I can apply the theory to the others.
First, this is some sample VBA code I've tested and which proved satisfactory for the basic task, just for a form. It is passed a date (dteDOP), then adds 3 months, (quarterly report)and loops until it exceeds the current date, thus generating the a due date for the the next report.
'initialize the due date
dteDueDate = dteDOP
'Add quarterly intervals, starting with (DOP + 3 months), until
'you exceed today's date
Do Until dteDueDate > Date
dteDueDate = DateAdd("m", 3, dteDueDate)
Loop
'set a text box to the next due date after today
Me.txtNextQuarDue = dteDueDate
Obviously, this isn't really a function at the moment, but it worked as a test of the logic, with instantly visible results.
This works, but I'd like to do it on the server end, so I can send out notifications. How would this be accomplished as an SQL stored procedure/function? Obviously, for that I'll need to again do a comparison of the current date with the due date for timing concerns, but that should be relatively simple. Also, I know that the '@' symbol is somehow part of variables in SQL Procedures/functions, could you give me a very basic explanation of this, especially the difference between @xxx and @@xxx?
Thanks in advance,
Stephen

Hi all--I'm trying to convert a function which I inherited from a SQL Server 2000 DTS package to something usable in an SSIS package in SQL Server 2005. Given the original code here:
Function Main()
on error resume next
dim cn, i, rs, sSQL
Set cn = CreateObject("ADODB.Connection")
cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>"
set rs = CreateObject("ADODB.Recordset")
set rs = DTSGlobalVariables("SQLstring").value
for i = 1 to rs.RecordCount
sSQL = rs.Fields(0).value
cn.Execute sSQL, , 128 'adExecuteNoRecords option for faster execution
rs.MoveNext
Next
Main = DTSTaskExecResult_Success
End Function
This code was originally programmed in the SQL Server ActiveX Task type in a DTS package designed to take an open-ended number of SQL statements generated by another task as input, then execute each SQL statement sequentially. Upon this code's success, move on to the next step. (Of course, there was no additional documentation with this code. :-)
Based on other postings, I attempted to push this code into a Visual Studio BI 2005 Script Task with the following change:
public Sub Main()
...
Dts.TaskResult = Dts.Results.Success
End Class
I get the following error when I attempt to compile this:
Error 30209: Option Strict On requires all variable declarations to have an 'As' clause.
I am new to Visual Basic, so I'm on a learning curve here. From what I know of this script:
- The variables here violate the new Option Strict On requirement in VS 2005 to declare what type of object your variable is supposed to use.
- I need to explicitly declare each object, unless I turn off the Option Strict On (which didn't seem recommended, based on what I read).
Given this statement:
dim cn, i, rs, sSQL
I'm looking at "i" as type Integer; rs and sSQL are open-ended arrays, but can't quite figure out how to read the code here:
Set cn = CreateObject("ADODB.Connection")
cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>"
set rs = CreateObject("ADODB.Recordset")
This code seems to create an instance of a COM component, then pass provider information and create the recordset being passed in by the previous task, but am not sure whether this syntax is correct for VS 2005 or what data type declaration to make here. Any ideas/help on how to rewrite this code would be greatly appreciated!

I've put a SelectCommand with an aggregate function calculation and AS into a SqlDataSource and was able to display the result of the calculation in an asp:BoundField in a GridView; there was an expression after the AS (not sure what to call it) and that expression apparently took the calculation to the GridView (so far so good).
If I write the same SELECT statement in a C# code behind file, is there a way to take the aggregate function calculation and put it into a double variable? Possibly, is the expression after an AS something
that I can manipulate into a double variable? My end goal is to insert the result of the calculation into a database.
What I have so far with the SelectCommand, the SqlDataSource and the GridView is shown below in case this helps:
<asp:GridView class="gridview" ID="GridView2" runat="server" AutoGenerateColumns="False" DataSourceID="lbsgalDataSource">
<Columns>
<asp:BoundField DataField="Formulation" HeaderText="Formulation" SortExpression="Formulation" />
<asp:BoundField DataField="lbs" HeaderText="lbs" SortExpression="lbs" />
<asp:BoundField DataField="gal" HeaderText="gallons" SortExpression="gal" />
<asp:BoundField DataField="density" HeaderText="density" SortExpression="density" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="lbsgalDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT
a.Formulation,
SUM (a.lbs) AS lbs,
SUM ((a.lbs)/(b.density)) AS gal,
( ( SUM (a.lbs) ) / ( SUM ((a.lbs)/(b.density)) ) ) AS density
FROM Formulations a INNER JOIN Materials b
ON a.Material=b.Material WHERE Formulation=@Formulation GROUP BY Formulation">
<selectparameters>
<asp:controlparameter controlid="DropDownList1" name="Formulation" propertyname="SelectedValue" type="String" />
</selectparameters>
</asp:SqlDataSource>

Hi,
I'm pretty new to SQL and I'm having trouble with a function, probably just syntax. I'm trying to consolidate several rows of data into a single row text field.
The calling program can use views but not functions so I need to get a table into a view with the consolidated lines.
Also, I would think this could be consolidated to a single view that calls one function. Is that possible, how would I do it?
Thanks for any help,
Steve

Hello, I am about out of hair from pulling it out. If someone could please show me what I'm doing wrong I would really appreciate it. I have this function for a SSRS 2005 report:
Public Function funAdditions(pFields As Fields) As Double
if pFields !FA00902_AMOUNT.Value > 0 and
pFields !FA00902_TRANSACCTTYPE.Value = 3 and
pFields !FA00902_DEPRTODATE.Value > Parameters!BeginDate.Value and
pFields !FA00902_DEPRTODATE.Value <= Parameters!CutOffDate.Value and NOT
instr(pFields !FA00902_SOURCDOC.Value, "FACHG")=1
then return pFields !FA00902_AMOUNT.Value
end
else if pFields !FA00902_TRANSACCTTYPE.Value = 3 and
pFields !FA00902_DEPRTODATE.Value > Parameters!BeginDate.Value and
pFields !FA00902_DEPRTODATE.Value <= Parameters!CutOffDate.Value and
instr(pFields !FA00902_SOURCDOC.Value, "FACHG")=1
then return pFields !FA00902_AMOUNT.Value
end
End Function
...and after much research cannot figure out the solution to this error:
[rsCompilerErrorInCode] There is an error on line 1 of custom code: [BC30201] Expression expected.
I'm new to SSRS so is there a syntax error I'm missing?
Thanks in advance,

I put a function in the code section of Report Properties. I went to add an expression and can't find the function. I type =code. and did not see the function I created in the list.
Here's my code below:
Code Snippet
Public Function ConvertToStartDate(ByVal StartDate As String) As DateTime
Select Case StartDate
Case "Today"
Return DateTime.Today
Case "Yesterday"
Return DateTime.Today.AddDays(-1)
Case "30DaysOut"
Return DateTime.Today.AddDays(+30)
Case "2DaysPrior"
Return DateTime.Today.AddDays(-2)
' Additional cases
Case Else
Throw New ArgumentException("Unknown argument, " & StartDate, "StartDate")
End Select
End Function
I should be able to put in expression =code.ConvertToStartDate.StartDate("Today"), but that does not work. I get a red squiggly line under StartDate.
Thanks for your help,

I have sql code that returns the correct number of record when run without an aggregate function like count(myfield) and group by myfield. It always returns 86 row which is correct when Select DISTINCT is used. As, expected when DISTINCT is not used I get double the number if rows or 172. But when I count(myfield) and group by myfield the count is 172 and not 86. The strangest thing about this is that when I am grouping a set of items
Group 1
Group 2
Group 3
The other group sum up correctly while others don't. What can explain this? Here is the code.
Select DISTINCT ws.p4Districtnumber, ws.cycle, ws.worksetid, count(msi.MeterSessionInputKey) as ASND
from fcs.dbo.WorkSet as ws
left outer join fcs.dbo.WorkAssignment as wa
on ws.WorkSetID = wa.WorkSetID
left outer join fcs.dbo.MeterSessionInput as msi
on wa.worksetkey = msi.worksetkey
[code]....

Now Sql Function can not modify data as Sql Procedure like other database, it's very troublesome at most case!
in most case, Sql Function is used to improve code structure then it can be maintanced easy! BUT only because it can not modify data, there are 2 troublesome way:
1. Make all callers in the path from Sql Functions to Sql Procedure. and the coder will cry, the code will become very
confusional , and very difficult to maintance.
2. Divide the Sql Function into a thin CLR wrapper to call a Sql Procedure, can only use another connection, BUT can not be in the same transaction context And the code is ugly and slow.
You should not give limitation to Sql Function, should just limit the using context of Sql Function!
The sql code is more difficult to read and maintance than norm code(C#), then the improving code structure and readability should be one of your most important task, that's why microsoft!

In the 70-461 objectives it says: Ensure code non regression by keeping consistent signature for procedure, views and function (interfaces); security implications...I think I understand what this means in general. They want us to be able to create a view that will still be able to call the original data even if the table is modified. In other words, the view table shouldn't easily be broken. ie, type a code that does NOT ensure non regression, then change the code so that it does ensure non regression.

Dear Friends,
I am having 2 Tables.
Table 1: AddressBook
Fields --> User Name, Address, CountryCode
Table 2: Country
Fields --> Country Code, Country Name
Step 1 : I have created a Cube with these two tables using SSAS.
Step 2 : I have created a report in SSRS showing Address list.
The Column in the report are User Name, Address, Country Name
But I have no idea, how to convert this Country Code to Country name.
I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]
Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.
Thanks in advance.

Hello,
I'm using ASP.Net to update a table which include a lot of fields may be around 30 fields, I used stored procedure to update these fields. Unfortunatily I had to use a FormView to handle some TextBoxes and RadioButtonLists which are about 30 web controls.
I 've built and tested my stored procedure, and it worked successfully thru the SQL Builder.The problem I faced that I have to define the variable in the stored procedure and define it again the code behind againALTER PROCEDURE dbo.UpdateItems
(
@eName nvarchar, @ePRN nvarchar, @cID nvarchar, @eCC nvarchar,@sDate nvarchar,@eLOC nvarchar, @eTEL nvarchar, @ePhone nvarchar,

CCHTitle = @CCHTitle, CCHsigdt = @CCHsigdt, username = @username, levent = @levent, eventdate = @eventdate, eventtime = @eventtime
WHERE (ePRN = @ePRN)
and the code behind which i have to write will be something like thiscmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@eName", ((TextBox)FormView1.FindControl("TextBox1")).Text);cmd.Parameters.AddWithValue("@ePRN", ((TextBox)FormView1.FindControl("TextBox2")).Text);
cmd.Parameters.AddWithValue("@cID", ((TextBox)FormView1.FindControl("TextBox3")).Text);cmd.Parameters.AddWithValue("@eCC", ((TextBox)FormView1.FindControl("TextBox4")).Text);
((TextBox)FormView1.FindControl("TextBox7")).Text = ((TextBox)FormView1.FindControl("TextBox7")).Text + ((TextBox)FormView1.FindControl("TextBox6")).Text + ((TextBox)FormView1.FindControl("TextBox5")).Text;cmd.Parameters.AddWithValue("@sDate", ((TextBox)FormView1.FindControl("TextBox7")).Text);
cmd.Parameters.AddWithValue("@eLOC", ((TextBox)FormView1.FindControl("TextBox8")).Text);cmd.Parameters.AddWithValue("@eTel", ((TextBox)FormView1.FindControl("TextBox9")).Text);
cmd.Parameters.AddWithValue("@ePhone", ((TextBox)FormView1.FindControl("TextBox10")).Text);
cmd.Parameters.AddWithValue("@eMobile", ((TextBox)FormView1.FindControl("TextBox11")).Text);
So is there any way to do it better than this way ??

I need to be able to pass the output of a function to another function as input, where all functions involved are user-defined in-line table-valued functions. I already posted this on Stack Exchange, so here is a link to the relevant code: [URL] ...
I am fairly certain OUTER APPLY is the core answer here; there's *clearly* some way in which does *not* do what I need, or I would not get the null output you see in the link, but it seems clear that there should be a way to fool it into working.

Recently in an SSIS package I am getting the following error for a particular Data flow task.
Error: 2008-01-25 12:01:48.58
Code: 0xC0202009
Source: Import Datasynapse Data User Events Source [3017]

Source: Import Datasynapse Data DTS.Pipeline
Description: component "User Events Source" (3017) failed the pre-execute phase and returned error code 0xC0202009.
End Error
Our guess is when the data size of User Events table is more it throws this error. If we try to transfer small subset of data it succeeds. What could be reason for this error?
Since this is very urgent, immediate response would be very much appreciated.
Thanks & Regards,

Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't...
I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it.
So the first thing I do, is I need to grab the primary key fields of the table. I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table. Great. I pass in the table name, and sure enough, it comes back with a record set, 1 row per column. That's exactly what I need.
Umm... This is the part where I'm at a loss. The stored procedure outputs the resultset as a resultset (Not as an output param). Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work. But... How do I use the resultset from the stored procedure? You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the syntax like:
DECLARE @table table@table=EXEC sp_pkeys MyTable
That of course just returns you the RETURN_VALUE instead of the resultset it output. Ugh. Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys. Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key. Ok, I test it and it works great.
Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out...
SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT)
Syntax Error. Ugh. Eventually, I even try:
SELECT *FROM Split(substring('abc,def',2,6),DEFAULT)
Syntax Error.
Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function?
SELECT *FROM Split('bc,def',DEFAULT) works just fine.
So my questions are:
Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it?
Is there any way to pass a scalar-valued function as a parameter into a table-valued function?
Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround:
DECLARE @tmp varchar(8000)
SET @tmp=(SELECT dbo.fn_pkeys('MyTable'))
SELECT *
FROM Split(@tmp,DEFAULT)

Hi All
Yesterday Peso was gracious enough to help me with creating function/views/sp's
I took those examples and extended what had from excel into function in SQL
however I see myself repeating certain parts of the query and i'm wondering if there is a way to call a function (in part or in whole) from another function?
Here are excerpts two functions I have:
We'll call this function UserUsage()
------------------------------------
RETURN(
SELECT ut.LastName, ut.FirstName,
CEILING(Sum(hu.session_time)/ 60000) AS [Time Spent(MIN)],
Max(hu.time_stamp) AS [Last Log Date],
pct.Title, cat.topic_name
FROM ZSRIVENDEL.dbo.UserTable ut,
ZSRIVENDEL.dbo.history_usage hu,
ZSRIVENDEL.dbo.pc_CourseTitles pct,
ZSRIVENDEL.dbo.cam_topics cat
WHERE ut.student_id = hu.student_id
AND hu.course_id = pct.CourseID
AND hu.topic_id = cat.topic_id
AND ((ut.ClientID=@ClientID)
AND (pct.ClientID=@ClientID)
AND (ut.GroupID=3400)
AND (hu.time_stamp>= @StartDate
And hu.time_stamp< @EndDate)
AND (hu.session_time<21600000))
GROUP BY ut.LastName, ut.FirstName, pct.Title, cat.topic_name
)
and will call this function UserSummary():
-----------------------------------------
RETURN (
SELECTut.LastName, ut.FirstName,
CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]
FROM ZSRIVENDEL.dbo.UserTable AS ut
INNER JOIN ZSRIVENDEL.dbo.History_Usage AS hu
ON hu.Student_ID = ut.Student_ID
WHERE ut.ClientID = @ClientID
AND ut.GroupID = 3400
AND hu.Time_Stamp >= @StartDate
AND hu.Time_Stamp < @EndDate
AND hu.Session_Time < 21600000
GROUP BY ut.LastName, ut.FirstName
)
As you can see the first part of the both query are simlar. In particular the:
SELECTut.LastName, ut.FirstName,
CEILING(SUM(hu.Session_Time) / 60000.0) AS [Time Spent(MIN)]
and also the variables @StartDate and @EndDate.
In C# it would create a method and just call that method as well as the variables. However i'm not sure how to do that with sql functions. Could someone shed some light please?
Thank you!
