Getting a simple function to run in the CLR . Please help :-(

Hi everyone,
If anyone can help me with the following, I would be very greatful.
I want to create a pretty basic function under sql server 2005's runtime.
I've made the assembly and attached it. And when I do something totally simp
le
like return a simple string it works fine. However when I try and use a conn
ection
object I get an exception as follows:
A .NET Framework error occurred during execution of user defined routine
or aggregate 'GetRolesString':
System.Security.HostProtectionException: Attempted to perform an operation
that was forbidden by the CLR host.
The protected resources (only available with full trust) were: All
The demanded resources were: UI
It seems to be suggesting that everything is protected and so I can't do
anything. That would be fine but I havent a clue how to unprotect them.
The things I've tried are:
1. Making the database property Trustworthy equal to true
2. Marking the Permission_Set for the assembly as EXTERNAL (or whatever it
is)
These things havent helped
A huge thank you to anyone who can tell me how to unprotect me crap :-)
Thanks gain

Using the connection object shouldn't be a problem. The error you're
getting looks like it has something to do with UI, in other words are
you trying to do a Console.WriteLine or something similar?
If you post your code for the method it'll be easier for us to see
what's wrong.Anyway, below follows some code snippets for the
connection:
public static void GetData() {
SqlConnection conn = new SqlConnection("Context Connection=true");
conn.Open();
SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "Select some data from somewhere";
SqlContext.Pipe.ExecuteAndSend(cmd);
}
Notice that in the code above it is not entirely necessary to use the
connection at all, as you are calling ExecuteAndSend on the SqlPipe
class.

Getting a Return value from a Function.

Im a self proclaimed newb and Im stuck on returning a value from a function. I want to get the AttendID that the SQL statement returns and dump it into strAttendID:Response.Redirect("ClassSurvey.aspx?Pupil=" & strAttendID)
I cant seem to accomplish this. It returns nothing. Please help.
TIA,
Stue
<code>
Function Get_AttendID(ByVal strAttendIDAsString)As SqlDataReader
Dim connStringAsString = ConfigurationSettings.AppSettings("ClassDB")
Dim sqlConnAsNew SqlConnection(connString)
Dim sqlCmdAs SqlCommand
Dim drAs SqlDataReader

sqlConn.Open()
Dim strSQLAsString = "Select AttendID from attendees Where FirstName=@.FirstName and LastName=@.LastName and classbegdt = @.classbegdt and survey = '0'"

sqlCmd =New SqlCommand(strSQL, sqlConn)

sqlCmd.Parameters.Add("@.FirstName", SqlDbType.VarChar, 50)
sqlCmd.Parameters("@.FirstName").Value = tbFirstName.Text
sqlCmd.Parameters.Add("@.LastName", SqlDbType.VarChar, 50)
sqlCmd.Parameters("@.LastName").Value = tbLastName.Text
sqlCmd.Parameters.Add("@.classbegdt", SqlDbType.DateTime, 8)
sqlCmd.Parameters("@.classbegdt").Value = calBegDate.SelectedDate.ToShortDateString
dr = sqlCmd.ExecuteReader()
dr.Close()
sqlConn.Close()

Return dr

EndFunction
</code>

Why are you returning a datareader if all you want is the attend id and why are you even using the datareader at all when all you are looking for is one value.
The best way would be to use executescalar method and return the value. excuse the sample code because it is C#

publicstring AttendID()
{
SqlConnection myConnection =new SqlConnection(ConfigurationSettings.AppSettings("ClassDB"));
string strSQL = "Select AttendID from attendees Where FirstName=@.FirstName and LastName=@.LastName and classbegdt = @.classbegdt and survey = '0'";
SqlCommand myCommand =new SqlCommand(strSQL, myConnection);
myCommand.Parameters.Add("@.FirstName", SqlDbType.VarChar, 50);
myCommand.Parameters("@.FirstName").Value = tbFirstName.Text;
myCommand.Parameters.Add("@.LastName", SqlDbType.VarChar, 50);
myCommand.Parameters("@.LastName").Value = tbLastName.Text;
myCommand.Parameters.Add("@.classbegdt", SqlDbType.DateTime, 8);
myCommand.Parameters("@.classbegdt").Value = calBegDate.SelectedDate.ToShortDateString();

return myCommand.ExecuteScalar().ToString();
}

|||Thanks Mansoorl! I tried that and it worked. In response to your question about the datareader, the reason I went this route is because I have another function wich requires pulling 2 values. So i was in that mindset. I didnt know about the ExecuteScalar though so thanks for educating me.
Do you mind explaining how i might go about returning 3 values via the data reader if:
Select FirstName, LastName, Company from TBClassSurvey Where AttendID=@.AttendID and SchedID=@.SchedID and survey = '0'";

Thanks again,
Stue
|||publicvoidAttendID()
{
SqlConnection myConnection =new SqlConnection(ConfigurationSettings.AppSettings("ClassDB"));
string strSQL = "Select AttendID from attendees Where FirstName=@.FirstName and LastName=@.LastName and classbegdt = @.classbegdt and survey = '0'";
SqlCommand myCommand =new SqlCommand(strSQL, myConnection);
myCommand.Parameters.Add("@.FirstName", SqlDbType.VarChar, 50);
myCommand.Parameters("@.FirstName").Value = tbFirstName.Text;
myCommand.Parameters.Add("@.LastName", SqlDbType.VarChar, 50);
myCommand.Parameters("@.LastName").Value = tbLastName.Text;
myCommand.Parameters.Add("@.classbegdt", SqlDbType.DateTime, 8);
myCommand.Parameters("@.classbegdt").Value = calBegDate.SelectedDate.ToShortDateString();

SqlDataReader myReader = myCommand.ExecuteReader();
myReader.Read();
string FirstName = myReader["FirstName"].ToString();
string LastName = myReader["LastName"].ToString();
string Company = myReader["Company"].ToString();
myReader.Close();
myConnection.Close();
}
The above code assumes you got something back in result of the query. If there is a possiblity for blank records make sure you use if (myReader.Read()) constuct.

Getting #Error with aggregate function

Why doesn't this return a value?
=Sum(IIf(Fields!GroupCode.Value = 10, Fields!Rating.Value, 0))
I am getting #Error as the value. This however gives me a value:
=Sum(IIf(Fields!GroupCode.Value = 10, 1, 0))
However, I need the above to work...I need it to sum the rating if it's
part of a particular group.Here are some additional findings...
The following code works:
=Sum(IIf(Fields!GroupCode.Value = 10, CInt(Fields!Rating.Value), 0))
The following code fails:
=Sum(IIf(Fields!GroupCode.Value = 10, 1.20, 0))
=Sum(IIf(Fields!GroupCode.Value = 10, CDbl(Fields!Rating.Value), 0))
Why is it that it can only sum up intergers?|||I figured it out!!
The following code works:
=Sum(IIf(Fields!GroupCode.Value = 10, 1.20, 0.0))
Both the true and false values need to be of the same type. By return
0 as my false condition value, and 1.2 as my true condition, it caused
it to fail because it's returning different data types base on the
different condition.
This is bad, MS needs to fix this.

getdate() within a function

Im really new to SQL SProcs. I have a function that I wrote that I am trying to compare a date within a record to today's date. The problem is that you cant call getdate from within a function... So, I was thinking that I could create a temp table that had a a date column with a default date of today and select that out. However, I cant find any documentation on how you would create a temp table with a default value, or if this would even work. I dont want to have to pass todays date into the function, nor do I want to have to create a permanent table just to hold this data.

Any help, or other ideas?

Thanks.

You would create a temp table with a default value the same way you would create a non-temp table with a default value, except start the table name with a #.

Why can't you select the date from within the function?

I can't help but feel that you are doing something more basic incorrectly, or with a bad approach to your problem, but without any code, it's hard to tell what you are trying to do.

|||

Originally, I was trying to do something like this:

SET @.resDate = (SELECT ...)

IF @.resDate > getdate()
...

That didnt work because you cant call getdate from a function. Then I tried:

CREATE TABLE #tempDate
(
today datetime
DEFAULT(getdate())
)

Which also did not work for the same reason. So... other than passing getdate into the function, is there any other way to do it?

Josh

You could also write a view that returns a datetime.

This is no more an issue in SQL 2005 though. So if you are using 2005, you are lucky.

|||what about this function(time1,getdate()). This is what I have ahad to use in the past.

GETDATE() with a user defined function

I have a requirement where i need to get the current time/date within a Function. As getDate function is a non deterministic function it can not be used with in a function. Your guidence in this regard is greately appreciated.

Pass GetDate() as a function argument.

Yes, I can write extended stored procedures. No, it isn't worth it for the average user, since it is a lot of work and you can break nearly all of the rules in an xp. If you don't know how/why you're breaking the rules, that can be a REALLY bad thing!

It explains everything there.
In a nutshell, you cannot use GetDate() inside a UDF.

GetDate() in User Defined Functions, Parameters in View

1) Am I right in believing I can't access the GetDate() function from within
a table valued UDF ... ? That seems to be what the syntax checker is
telling me. Any suggested workarounds ?
2) I tried create a view which used a table valued UDF, with " getdate() "
as a parameter, in the view's from clause and the system didn't like that
either ... Any suggestions ? Are there ways of parameterizing a view ?
3) I need the view construct because I need to reference the returned
dataset from Analysis Services as a dimension. I prefer the UDF construct
(as opposed to selecting off a table with a where clause) because I don't
have to build a process to add new date records to the hypothetical table.
Performance isn't really an issue, because the only place the view is invoke
d
is in processing a cube in Analysis Services.
4) Some SQL
...
CREATE FUNCTION dbo.tfun_Date (
@.EndDate smalldatetime) --added when getdate didn't work

the GETDATE/CURRENTTIMESTAMP function.
Then just use that new parameter as your getdate()

Correct. However, you can create a view that has the GetDate() in it and
then call that view from your UDF. This workaround may or may not continue
to work in future versions.

An in-line table-valued UDF is a parameterized view. I think the problem
is still the GetDate() which cannot be a parameter to a UDF either. (Why
not? Because. Technically it is the issue of whether a function always
returns the same value or not.)

getdate() in user defined function

Hi,

It is possible to use getdate() in userdefined function. If so, how to do the same ?

The following code throws error :

create function function1
return varchar
DECLARE @.currYYMM VARCHAR(20)
SET @.currYYMM = convert(char(4),getdate(),12)
// Here it says the error 'getdate' can't be used inside functions
............
................If I recall correctly, a scalar user defined function must return a deterministic value (ie, if you pass in the same parameters, you will get the same results). A non-deterministic function, would take a randomizer (such as GetDate()) and return a different result everytime you called it (even when calling it with the same parameters). I don't believe that this is allowed.

hmscott

GETDATE() in a Function

Hi again.
I'm trying to write a user-defined function that accepts only one parameter, a date.
The function then calculates the amount of days elapsed between the specified date,
and the current system-date. I'm using DATEDIFF together with GETDATE() to try and
calculate the difference, but GETDATE() keeps on causing an error.
Can one use GETDATE() in a function?
I tried to call a stored procedure from the same function, and an error states that
only extended stored procedures or functions can be called from within the function...
Any way to bypass this?
Hi,
No, You cannot use getDate() inside a function. Non deterministic values can
not be used inside a function.(Te value og getdate changes every milli
second)
Solution1 :
The solution is Create view as select getDate() as currdate
and then use the view inside the function.
Thanks

GETDATE() Function Issue

Hi Everyone,
I'm running into an issue trying to update a column on a remote database.
The server is linked from the server I'm calling this update statement. The
syntax is as follows:
UPDATE Server1.Test.dbo.Testdata
SET dtUpdated = GETDATE()
WHERE intID = 111
The problem is that the update takes a very long time to complete. Now if I
declare a variable with a datetime and set that variable to GETDATE(), the
update takes seconds. Is there some known issue? Can anyone help with this
?
I have noticed that I can update small size tables, but it takes much longer
to update large size tables. The columns in the "Where" clause have indexes
on them and that can't be the issue since my test using the variable worked
quicker. I'm just wondering why I can't use the GETDATE() function directly
.
DarrenDarren
No, it works fine with GETDATE() function too. Please take a look at
execution plan of the query (with GETDATE() and without) and see what is
going on

Madhivanan|||I looked at the execution plan and it is doing what I thought it would. The
execution plan shows that it does a remote scan to look at the whole table
then it will filter by the where clause. This is the source of my problem.
For a large table that holds over 4 million records, it has to scan that
whole table before filtering on the primary key I'm already passing it. I
don't understand why on the remote server it must scan the whole table
instead of already filtering by the where clause. When I use a variable to
update the date column it shows a remote query for the update. Why is this
happening? Did some setting happen that I don't know about? How can I trac
k
down this issue?

have a look at this:

Rgds,
Paul Ibison, SQL Server MVP|||Mark,
You really need to understand that SQL Server does not have a DATE or a TIME
datatype. It only has DATETIME or SMALLDATETIME. It either case it always
includes the time portion. Even if you declare a DATETIME and only specify
the date portion it will automatically add the time of midnight. The only
want to display just the date portion (without using a gui that formats it
for you) is to convert it into a string. In your case you are trying to
stuff it back into a smalldatetime datatype which will simply add the time
portion back on again. Change the datatype of the variable to varchar and
you will make life a lot easier.

Even passing the date to a stored procedure will not work. The database
will STORE your date as a datetime type which means if you pass '13/07/2005'
it will store it as '13/07/2005 00:00:00.000'. You can use an app to only
display and edit the date, but the date will always store as a datetime type
(which will add a MIDNIGHT time). You can also use the convert function to
display your datetime as just a "date string" using CONVERT(VARCHAR(10),
GETDATE(), 103) but as you can see, this actually converts your date into a
string and is treated as a string from then on (sorting is string based
then). Now if you actually want it strip out the time element of GETDATE()
you can use CAST(CONVERT(VARCHAR(10), GETDATE(), 102) AS DATETIME) which
will give you today's date with a midnight time. This will match any where
statement where you just specify just a date e.g. DateField = '2005-07-13'
because this will be converted automatically to '2005-07-13 00:00:00.000'
The question is "Why do you care so much that the database ONLY store the
date?" After all, the database never stores '13/07/2005' in that exact
format anyway. It stores it as a floating value that is calculated from a
set point in time. If you store something in a datetime field, I can get it
out in any format I desire (see the table listing under the "CAST and
CONVERT" topic in BOL). Which is the way it should be to allow for
international usage. In the UK you can display it in UK style and in the US
you can display in the US style. Same date, just displayed differently.

i fixed it with this crazy procedure, surely theres an easier way
declare @.todaysdate smalldatetime
select @.todaysdate= getdate()
declare @.month varchar(10)
select @.month =datepart(mm,@.todaysdate)
declare @.day varchar(10)
select @.day =datepart(dd,@.todaysdate)
declare @.year varchar(10)
select @.year =datepart(yyyy,@.todaysdate)
select @.todaysdate = @.day +'/' + @.month + '/' + @.year

You really need to understand that SQL Server does not have a DATE or a TIME
datatype. It only has DATETIME or SMALLDATETIME. It either case it always
includes the time portion. Even if you declare a DATETIME and only specify
the date portion it will automatically add the time of midnight. The only
want to display just the date portion (without using a gui that formats it
for you) is to convert it into a string. In your case you are trying to
stuff it back into a smalldatetime datatype which will simply add the time
portion back on again. Change the datatype of the variable to varchar and
you will make life a lot easier.

GetDate() as parameter to UDF

I understand that GetDate() cannot be used within the *body* of a
user-defined function because it is non-deterministic.
I now have a table-valued function with which I want to use DateAdd and
GetDate() as *parameters* -- thus:
Select * From dbo.MyFunction(DateAdd(mm,-6,getdate()), getdate()).
I get "Incorrect syntax near '('.
The same happens if I eliminate the DateAdd. If I use hard-coded dates,
e.g. '1/1/2006', the function works as expected.
What am I doing wrong?
Thanks.

Use a view instead...
here is an exemple :
CREATE VIEW dbo.V_DATE_TIME_DTM
AS
SELECT CURRENT_TIMESTAMP AS DTM_TIMESTAMP
GO
CREATE FUNCTION dbo.F_CURRENT_DATE ()
RETURNS DATETIME
AS
BEGIN
-- date/time with time to ZERO
DECLARE @.D DATETIME
SELECT @.D = dbo.F_DATEONLY(DAT_DATE)
FROM dbo.V_DATE_DAT
RETURN @.D
END
GO
A +
