Datetime Query Issue With C# Stored Procedure
Sep 9, 2007
Ok, i am using the convert function to get the date format from my datetime column. My problem is when C# try's to pull the column name the column name is not sent in the query. When I run the query in the query analyzer the column name is blank in the result window. How can I get the date from the record with out losing the name of my column in the query. My data binding needs the name of the column to bind the data to the drop down list control. Here is the statement:
SQL statement
SELECT DISTINCT convert(datetime, eventDT, 110) FROM tblRecognition
C# code
ddlDateTo.DataSource = _uiCode.Fill.Date();
ddlDateTo.DataTextField = "eventDT";
ddlDateTo.DataBind();
Thank you,

Hello,
I have got an SQL server stored procedure, and I would like to get this stored procedure, dbo.SpDate_Time_Minute_Today below executed against a matching or exact datetime from the database tables, PRODUCT_SALES.
Code Block
CREATE PROCEDURE dbo.SpDate_Time_Minute_Today
AS
SELECT PROD_SAL_DESC FROM PRODUCT_SALES
WHERE (CONVERT(CHAR(11), PROD_SAL_BY_DATE, 103) + ' ' + SUBSTRING(CONVERT(CHAR(17), PROD_SAL_BY_DATE, 100), 13, 19) = CONVERT(CHAR(11), CURRENT_TIMESTAMP, 103)
+ ' ' + SUBSTRING(CONVERT(CHAR(17), CURRENT_TIMESTAMP, 100), 13, 19))
/* SET NOCOUNT ON */
RETURN
PRODUCT_SALES has columns like this:
PROD_SAL_NO
PROD_SAL_BY_DATE
PROD_SAL_DESC
PROD_SAL_MFR
PROD_SAL_DEPT
Please do anyone here know how I can achieve this please. Thanks.

When I run the following code I get error "Incorrect syntax near 'MyStoredProcedureName".
Code Snippet
public static string GetWithDate(string date)
{
string connString = System.Configuration.ConfigurationManager.ConnectionStrings["Development"].ToString();
SqlConnection conn = new SqlConnection(connString);
conn.Open();
XmlDocument xmlDoc = new XmlDocument();
SqlCommand cmd = new SqlCommand("usp_SVDO_CNTRL_GetPalletChildWorkExceptions", conn); //sw.WriteLine(count++);
cmd.Parameters.Add(new SqlParameter("@date", date));
try
{
cmd.ExecuteReader();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
SqlDataReader rdr = cmd.ExecuteReader(); //<---Bombs
if (conn != null)
conn.Close();
return xmlDoc.InnerXml;
}
I'm assuming this is because my Date is in the wrong format when .NET passes it. I've tested the stored procedure directly in SQL Server Managent Studio and it works (Format of date is '5/15/2008 9:16:23 PM').

I have a stored procedure called from ASP code, and when it is executed, the stored procedure takes in a date as an attribute.
But since the stored procedure call is really just a string in the code, it is taking in the value as a string. So in my stored procedure, I want to convert a string value to a date value.
Any idea how this is done?

In a VB.NET script, I am adding the dbnull value to a parameter that will populate a smalldatetime column:
cmd.Parameters.Add("@unitHdApprove", System.DBNull.Value.ToString)
The stored procedure then defines the input as smalldatetime:
@unitHdApprove smalldatetime,
However, the result is that the record is inserted with 1/1/1900 as the date value, instead of <NULL>.
I'm guessing that this occurs because the conversion of a '' to date will return 1/1/1900, and VB requries the parameter value to be a string (at least with this syntax), so System.DBNull.Value.ToString really equals ''.
I've rewritten the proc to accept the date as a string instead, and then for each date, cast it to a smalldatetime or set it to null as is appropriate. But this is a really bulky way to do things with more than a few dates! Is there any way to change what is in my VB code so that the procedure will insert the actual null value?
Thanks,
Sarah

Hi I'm new to MS SQL and trying to write a very small dynamic stored procedure which is giving me a headache.
What I have is:
CREATE PROCEDURE busy_report
@TableName varchar(255),
@reporteddate datetime=NULL
AS
if @reporteddate is null
select @reporteddate = CURRENT_TIMESTAMP
-- Create a variable @SQLStatement
DECLARE @SQLStatement varchar(255)
SET DATEFORMAT dmy
-- Enter the dynamic SQL statement into the
-- variable @SQLStatement
SELECT @SQLStatement = "SELECT vendor, reporteddate, count(vendor) FROM " +
@TableName + "WHERE reporteddate = ' "
+ @reporteddate + " '"
-- Execute the SQL statement
EXEC(@SQLStatement)
GO
The error I keep getting is:
Server: Msg 8114, Level 16, State 4, Procedure busy_report, Line 0
Error converting data type varchar to datetime.
Any ideas appreciated.
(Edit:)
I've also tried it this way:
CREATE PROCEDURE UK_busy_report
@TableName varchar(255),
@reporteddate datetime=NULL
AS
-- Create a variable @SQLStatement
DECLARE @SQLStatement varchar(255)
SELECT @reporteddate=CONVERT(datetime, @reporteddate)
IF @@ERROR <> 0 BEGIN
/* Do some error processing */
PRINT 'Error Occured' END
ELSE
-- Enter the dynamic SQL statement into the
-- variable @SQLStatement
SELECT @SQLStatement = "SELECT vendor, reporteddate, count(vendor) FROM " +
@TableName + "WHERE reporteddate = ' "
+ @reporteddate + " '"
-- Execute the SQL statement
EXEC(@SQLStatement)
GO
Which gives me the same error!
.logic.

Hi,
I'm having a problem with inserting a datetime value into a database using VB.net and a Stored Procedure. Below is my stored procedure code and VB.net code. Could somebody please tell me what I am doing wrong ... I am almost frustrated to tears .
Stored procedure:
ALTER PROCEDURE dbo.SPTest
@testvalue DATETIME
AS
INSERT INTO tbl_Rates VALUES (1.2, 1.3, @testvalue, 'EUR/USD')
RETURN 1
VB.NET code:
Dim RatesTA As New RatesDataSetTableAdapters.RatesTableAdapter
Dim ReturnVal As Object
ReturnVal = RatesTA.SPTest(Now)
Console.WriteLine(CType(ReturnVal, Integer))
When I run this the ReturnVal is 0.
I should also mention that my system uses the dd/mm/yyyy date format (Australian) and I am using VB.NET Express and SQL Server Express.

Hi Everyone,I've been battling this for two days with no luck. I'm using SQLServer 2000.Here's the mystery: I've got a stored procedure that takes a singlevarchar parameter to determine how the result set is sorted. Here itis:CREATE PROCEDURE spDemo @SortField varchar(30)ASSELECT dtmTimeStamp, strEmpName, strOld, strNew, strActionDescFROM ActivityLogORDER BY CASE @SortFieldWHEN 'dtmTimeStamp' THEN dtmTimeStampWHEN 'strEmpName' THEN strEmpNameWHEN 'strOld' THEN strOldWHEN 'strNew' THEN strNewWHEN 'strActionDesc' THEN strActionDescENDGOWhen I execute the stored procedure in the Query Analyzer, it worksperfectly ONLY IF the @SortField parameter is 'dtmTimeStamp' or'strNew'. When passing in any of the other three possible values for@SortField, I get the following error:Server: Msg 241, Level 16, State 1, Procedure spDemo, Line 4Syntax error converting datetime from character string.Now instead of executing the stored procedure, if I copy and paste theSELECT statement directly into the Query Analyzer (after removing theCASE statement and manually trying each different value of @SortField),it works fine for all five possible values of SortField.Even though the error points to Line 4 of the stored procedure, itseems to me that the CASE statement is causing problems for some, butnot all, values of the @SortField parameter.Any ideas?Thanks,Jimmy

Has anyone encountered cases in which a proc executed by DTS has the following behavior:
1) underperforms the same proc when executed in DTS as opposed to SQL Server Managemet Studio
2) underperforms an ad-hoc version of the same query (UPDATE) executed in SQL Server Managemet Studio
What could explain this?
Obviously,
All three scenarios are executed against the same database and hit the exact same tables and indices.
Query plans show that one step, a Clustered Index Seek, consumes most of the resources (57%) and for that the estimated rows = 1 and actual rows is 10 of 1000's time higher. (~ 23000).
The DTS execution effectively never finishes even after many hours (10+)
The Stored procedure execution will finish in 6 minutes (executed after the update ad-hoc query)
The Update ad-hoc query will finish in 2 minutes

Please help, i tried the following:
1. SELECT CURRENT_TIMESTAMP; ////// shows up with - & : , I want single string as in above example.2.
select cast(datepart(YYYY,getdate()) as varchar(4))+cast(datepart(mm,getdate()) as char(2))+convert(varchar(2),datepart(dd,getdate()),101 )+cast(datepart(hh,getdate()) as char(2))+cast(datepart(mi,getdate()) as char(2))+cast(datepart(ss,getdate()) as char(2))+cast(datepart(ms,getdate()) as char(4))
This one doesnot display day correctly, it should show 01 but shows 1

For some reason, I run a stored procedure in Query Analyzer and it works fine. When I run the very same procedure in MS access by clicking on its link I have to run it twice. The first run gives me the message that the stored procedure ran correctly but returned no records. The second run gives me the correct number of records but I have to run it twice. I am running month-to-month data. The first run is Jan thru March. Jan and Feb have no records so I run three months on the first set. The ensuing runs are individual months from April onward. The output is correct but any ideas on why I have to do it twice in Access? I am a bit new to stored procedures but my supervisor assures me that it should be exactly the same.

Seems like I'm stealing all the threads here, : But I need to learn :) I have a StoredProcedure that needs to return values that other StoredProcedures return.Rather than have my DataAccess layer access the DB multiple times, I would like to call One stored Procedure, and have that stored procedure call the others to get the information I need. I think this way would be more efficient than accessing the DB multiple times. One of my SP is:SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, S.Name AS 'StatusName', S.ItemDetailStatusID, S.InProgress as 'StatusInProgress', S.Color AS 'StatusColor',T.[Name] AS 'TypeName', T.Prefix, T.Name AS 'ItemDetailTypeName', T.ItemDetailTypeID FROM [Item].ItemDetails I INNER JOIN Item.ItemDetailStatus S ON I.ItemDetailStatusID = S.ItemDetailStatusID INNER JOIN [Item].ItemDetailTypes T ON I.ItemDetailTypeID = T.ItemDetailTypeID However, I already have StoredProcedures that return the exact same data from the ItemDetailStatus table and ItemDetailTypes table.Would it be better to do it above, and have more code to change when a new column/field is added, or more checks, or do something like:(This is not propper SQL) SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, EXEC [Item].ItemDetailStatusInfo I.ItemDetailStatusID, EXEC [Item].ItemDetailTypeInfo I.ItemDetailTypeID FROM [Item].ItemDetails IOr something like that... Any thoughts?

When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

Hey :)I'm facing a lot of troubles trying to create a new pause/break-system. Right now i'm building up the query that counts how many records that is inside 2 fields. Let me first show you my table:
ID (int) | stamp_start (Type: DateTime) | stamp_end (Type: DateTime) | Username (varchar)0 | 17-03-07 12:00:00 | 17-03-07 12:30:00 | Hovgaard
The client will enter a start time and a end time and this query should then count how many records that are inside this periode of time.
Example: The client enter starttime: 12:05 and endtime: 12:35.The query shall then return 1 record found. The same thing if the user enters 12:20 and 12:50.My current query looks like this:SELECT COUNT(ID) AS Expr1 FROM table WHERE (start_stamp <= @pausetime_start) AND (end_stamp >= @pausetime_end)But this will only count if I enter the exact same times as the one inside the table.Any ideas how I can figure this out?Thanks for your time so far :)/Jonas Hovgaard - Denmark

select @Answer = col3 +', 3'
from myTable
where Id= @IdreturnGO but for some reason, it only process's the first select statment and if nothing is in the column, it returns - ', 1' cheers!!!

In access, I can create a function that I can call in a query. It runs that function iteratively. Do I have the same ability with SQL server? Can I call a stored procedure WITHIN a query? I would like to be able to do something like:
Insert into tblOrders(spFirst_Name) Select {Call spUpperLower(tblClients.First_Name)} from tblClients Where ...
So basically, spUpperLower would run on every First Name Row in the result set.
Any help would be much appreciated.
Thanks,
Brad

Hi,
I have created an SQL query which returns the expected data. However, when I try to run it as a stored procedure, I get no rows returned.
(I assume I running the procedure correctly e.g. exec getNonDeployed RCN20047)
Code:
CREATE PROCEDURE getNonDeployed
@packageID text
AS
BEGIN
DECLARE @CollectionID VARCHAR(10)
DECLARE @Collections TABLE (CollectionID VARCHAR(10))
set @CollectionID = (SELECT
CollectionID
from ProgramOffers
where OfferID='@packageID');
WITH CollectionFull (SubCollectionID) AS
(
-- Create the anchor query. This establishes the starting
-- point
SELECT
SubCollectionID
from v_CollectToSubCollect a
where a.SubCollectionID=@CollectionID
UNION ALL
-- Create the recursive query. This query will be executed
-- until it returns no more rows
select
a.SubCollectionID
from v_CollectToSubCollect a
inner join CollectionFull b on b.SubCollectionID=a.ParentCollectionID
)
Insert Into @Collections
SELECT * FROM CollectionFull
select a.RuleName AS MACHINENAME, c.IPAddress0 as IPADDRESS
from v_CollectionRuleDirect a
inner join @Collections b on b.CollectionID=a.CollectionID
inner join v_GS_DEVICE_NETWORK c on c.ResourceID=a.ResourceID
where RuleName not in (select distinct a.MachineName as MACHINENAME
from v_StatusMessage a, v_StatMsgAttributes b, v_CollectionRuleDirect c, v_GS_DEVICE_NETWORK d, v_Collection e
where (a.RecordID=b.RecordID AND a.MachineName=c.RuleName and c.ResourceID=d.ResourceID and c.CollectionID=e.CollectionID)
AND b.AttributeValue IN ('@packageID'))
END

Hi All:
I have a situation where Im calling a stored procedure to insert some information.
When this information is inserted it is given a date/time stamp - say something in Aug.
There will be some corresponding records from the previous month already in the database that have some additional information that was manually added.
I need to query the corresponding records from the previous month and insert that info into the records that were just inserted.
the problem Im having is that i need to grab the most recent corresponding record. could be a day or a month prior to the one I just inserted. the also could be a record for months prior to that.
So how do i get the most recent corresponding record to my inserted record
Any suggestion on how to query this? and then pass the result to an udpate statement

Is there any way to do the following?select Max(FieldOne) From (spGetSomeData 100,'test' )Or do I need to define a view and have the stored proc use that view?The stored proc does some things with temp tables that would bedifficult to replicate with a view which is why I'm asking.
