Return Value from Stored Procedure

18-Jun-07 14:26

Create a function to calcualte the difference and format it as you need it.

Something like this:

CREATE FUNCTION dbo.TimeDifference(@startTime DATETIME, @endTime DATETIME)
RETURNS VARCHAR(20)
AS
BEGIN
    DECLARE @Diff int;
    DECLARE @Day int;
    DECLARE @Hour int;
    DECLARE @Minute int;

    SELECT @Diff = DATEDIFF(minute, @startTime, @endTime);
    SELECT @Day = @Diff / 3600;
    SELECT @Hour = (@Diff - (@Day*3600)) / 60;
    SELECT @Minute = @Diff % 60

    RETURN CAST( @Day AS VARCHAR(5)) + 'd ' +
           CAST( @Hour AS VARCHAR(5)) + 'h ' +
           CAST( @Minute AS VARCHAR(5)) + 'm'; 
    
END
GO
 
CREATE PROCEDURE dbo.MyProcedure
AS
BEGIN
    SELECT 
        tck.tcktreceived, 
        tck.ticketid, 
        tckmsg.tcktmessage, 
        dbo.TimeDifference(tct.tckreceived, GETDATE())
    FROM tbtickets AS tck 
    INNER JOIN tbticketsmessages AS tckmsg ON tck.ticketid = tckmsg.ticketid 
END
GO

I have a stored proceure whic is returning a table. Now I need ADO.Net statement So that IO can pass parameters to this stored procedure and get Retuened table from stored procedure.

Could you please send me code how can I reterive a returen value of tyoe table from stroed procedure in ADO.Net

Tnanks.

You don't return tables from a stored procedure, you SELECT them. It will then return as a result set.

Off the top of my head, something like this will work:

SqlConnection conn = new SqlConnection(myConnectionString);
SqlCommand cmd = new SqlCommand();
cmd.Connection = conn;
cmd.CommandText = "MyStoredProcedureName";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@MyParameter", theValueOfTheParameter);
SqlDataReader reader = cmd.ExecuteReader();
while(reader.Read())
{
    // Use the Get...() methods to get at the data.
    // Each loop retrieves one row from the result set.
}

The stored procedure needs to SELECT the data, as I told you before, in order for it to be collected.

CREATE PROCEDURE dbo.MyStoredProcedureName
@MyParameter INT
BEGIN
    SELECT * FROM MyTable WHERE SomeColumn = @MyParameter
END

Again thanks a lot but When I execute only this portion it gives me error

Syntax error converting the varchar value '2d 0h 0m' to a column of data
type int.

My stored procedure is the following.

Followed is the SQL Script and you can use this code in your SQL Function to
get the difference and make function with StartDate and EndDate parameters
and return the @Diff

DECLARE @Day INT
DECLARE @Hour INT
DECLARE @Minute INT
DECLARE @Start_Date DateTime
DECLARE @End_Date DateTime
SET @Start_Date = '6/13/2007 12:38 AM'
SET @End_Date = '6/14/2007 11:59 PM'
SET @Day = DATEDIFF( day, @Start_Date, @End_Date)
SET @Hour = DATEDIFF(hour , @Start_Date, @End_Date)
SET @Minute = DATEDIFF(minute , @Start_Date, @End_Date)
SET @Minute = @Minute-(@HOUR* 60)
SET @Hour = @Hour-(24* @Day)
SET @Diff = CONVERT( Varchar, @Day) +'d ' + CONVERT(Varchar , @Hour) + 'h '
+ CONVERT(Varchar , @Minute) +'m'
PRINT
'Difference : ' + @Diff

Hi Seema

The @Diff variable should be something like a varchar(20). Try the following:

DECLARE @Day INT 
DECLARE @Hour INT 
DECLARE @Minute INT 
DECLARE @Start_Date DateTime 
DECLARE @End_Date DateTime
DECLARE @Diff VARCHAR(20)
SET @Start_Date = '12 jun 2007 12:36' 
SET @End_Date = '14 jun 2007 12:35' 
SET @Day = DATEDIFF(minute, @Start_Date, @End_Date) / (24 * 60)
SET @Hour = (DATEDIFF(minute, @Start_Date, @End_Date) / 60) % 24
SET @Minute = DATEDIFF(minute, @Start_Date, @End_Date) % 60
SET @Diff = RTRIM(
   CASE WHEN @Day > 0 THEN CONVERT(Varchar, @Day) + 'd ' ELSE '' END +
   CASE WHEN @Hour > 0 THEN CONVERT(Varchar, @Hour) + 'h ' ELSE '' END +
   CASE WHEN @Minute> 0 THEN CONVERT(Varchar, @Minute) + 'm ' ELSE '' END)
PRINT 'Difference : ' + @Diff

If you use it a lot then perhaps you should set this up as a UDF.

Andy

Try

SELECT @itemReceived = tck.tcktreceived 
FROM tbtickets AS tck 
INNER JOIN tbticketsmessages AS tckmsg ON tck.ticketid = tckmsg.ticketid

The same goes for the other two SETs with a SELECT in them.

I don't think you can do either of those things.

If you want to return a result set from a stored procedure SELECT it:

SELECT * FROM @table

Set Time Part Of DateTime

18-Jun-07 13:10

You have declared @Diff as an integer. You have supplied it with a string that cannot be interpreted as a number.

Either Diff is incorrectly declared, or you need to find a way to convert the string to an appropriate number.

CDATA Sections in For XML query

Hi Guys,

I have a stored proc that is returning XML to the client, as listed below.
The question I have is that the description field can contain some HTMLa and possibly some illegal XML characters i.e &,<,>, ' etc.
I would like to wrap these sections in a CDATA field but am a little unsure how to do it.

Oh yeah the XML is going to be transformed by XSLT on the client.

Any tips would be greatly appreciated.
Ideally what I would like to achieve is to get rid of calling my DBO.HTMLENcode function I have written to encode the illegal characters.

Select @Brief as briefdescription,<br />
Cast('' + replace(cast(DBO.HTMLENcode(@Desc) as varchar(max)) , char(13),'' ) + '' as xml) as descriptions ,<br />
cast('' + replace(cast(DBO.HTMLENcode(Features) as varchar(max)), char(13)+char(10), '') + '' as xml) AS Features,<br />
cast(price as money) as price, bedrooms as bedroom, status_id,<br />
cast(replace(('' + replace(cast(DBO.HTMLENcode(rooms) as varchar(max)), char(13), '')+ ''),'','') as xml) as rooms,<br />
Size_metre_sq as sqm,<br />
COALESCE (ADDRESS1 + ', ', '') + COALESCE (ADDRESS2 + ', ', '') + COALESCE (ADDRESS3 + ', ',<br />
'') + COALESCE (ADDRESS4, '') AS Address ,directions ,<br />
Saleterms.SALETERMS as saleterm ,Saleterms.price_label as PriceLabel, leaseterms, rating,<br />
<br />
Convert(varchar(11) ,Availability, 113) as availability<br />
<br />
from dbo.PROPERTY as Property<br />
inner join Saleterms on Property.Saleterms_ID = Saleterms.ID<br />
where Property.id = @id<br />
FOR XML PATH('Property'), ROOT('Detail')

Database documentation tool recommendations?

Max Stayner18-Jun-07 4:55

Hi,

Long time listener, first time caller...

I've got a reasonably significant database in production (120 tables, 100+ UDFs and SPs) and (horrors) no real documentation for it. That's been (sort of) OK up to now because I've been the sole developer, but now more folks are going to be working on it, so I need to document it.

Does anyone have any recommendations for tools to use? I'd like to be able to:
- Record EXTENSIVE notes about tables, columns, functions, SPs, indexes
- Ideally, record relationships between functions, i.e. to be able to group related functions together
- Generate a nice ER diagram.
- Print things out nicely

Thanks in advance!

Max.

Query sql datatype Sql server 2005 [modified]

How can I dynamically query the xml in an xml datatype field?

The functions ive used are value, exist - but these assume you know the names of the xml tags.

The xml that the field holds is dynamic, so if the field contains something like:
<field1>value1</field1><field2>value2</field2>

I want the select statement to return the contents of a temp table:
field1 field2
------- -------
value1 value2

Is this possible in a select statement?

Many thanks in advance.

It is possible to do this using embedded SQL, but is this really a valid design. Following the creation of the table, you would somehow have to be able to insert records into this table, update it and so on. The ability to do this would have to be persisted somewhere in your calling application. Are you really sure that this is what you want to do?

Deja View - the feeling that you've seen this post before.
