Simple SQLParameter Question
Aug 2, 2006
I am just learning ASP.net, been reading over data grids but I am having a tough time understanding what the parameter line would be used for. I have read the MSDN regarding parameters, they seem to make sense. But the whole System.Byte(0) I cannot understand.
sqlUpdateCommand1 = new SqlCommand();
sqlUpdateCommand1.Parameters.Add(new SqlParameter("@Original_SSN", SqlDbType.VarChar, 11, ParameterDirection.Input, false, ((System.Byte)(0)), ((System.Byte)(0)), "SSN", DataRowVersion.Original, null));
Any pointers or tutorials regarding this is much appreciated.
Thanks,
Rishi Dhupar

I'm using parameters to record into database like:
SqlParameter paramId_empresa = new SqlParameter("@Id_empresa", SqlDbType.Int, 4);
paramId_empresa.Value = idEmpresa;
myCommand.Parameters.Add(paramId_empresa);
And set sql server field to allow null values and default value as (null)
Trouble is I'm getting an Input string was not in a correct format. when the field is blank
Line 182:Line 183: myConnection.Open();Line 184: myCommand.ExecuteNonQuery();Line 185: myConnection.Close();Line 186: }
Thanks a lot for any help

I am unable to set the value of my SqlParameter unless it is to a string.sqlCmd.Parameters.Add('@myParameter', SqlDbType.Bit).Value := false;
Setting it to false or 0 results in error: "Incompatible types: 'Object' and 'Boolean' (or 'Integer')"
I've tried to cast them as objects and that didn't work. I don't understand why something like 'false' (as a string) will.
FYI: I'm using Delphi.NET and hating it.

Im trying to execute the following:mySqlCmd.Parameters.Add("@Parent_ID", SqlDbType.Int).Value = (sectionUpdate.iSection.ParentID == 0 ? DBNull.Value : myParentID); However i get an error that Null cant be converted to Int. Is there any way i can uyse the SqlParameters approach but pass in a Null value for the field or must i wrap the entire connection within a IF/ELSE statement one containing a hard-coded NULL within the query and the other as a standard parameter with a proper int value? Thanks

Hi I am writing an app in flash which needs to hook up to MS SQL via asp.I need the code below to pass the var (ptodaysDate) to the sql statement. I can hard code it in and it works great but I really need to pass the var from flash.Pulling my hair out here, not much left to go.Any help greatly appreciated.---------------------------------------------- [WebMethod] public Schedule[] getSchedule(int ptodaysDate) { SqlDataAdapter adpt = new SqlDataAdapter("SELECT scheduleID, roomName, eventType,unitName,groupName,staffName,staffName2,theDate,theEnd FROM tb_schedule Where theDate >= @rtodaysDate", connString); SqlParameter rtodaysDate = new SqlParameter("@rtodaysDate", ptodaysDate); DataSet ds = new DataSet(); ArrayList al = new ArrayList(); adpt.Fill(ds); foreach (DataRow row in ds.Tables[0].Rows) { Schedule obj = new Schedule(); obj.scheduleID = (int)row["scheduleID"]; obj.roomName = (string)row["roomName"]; obj.eventType = (string)row["eventType"]; obj.unitName = (string)row["unitName"]; obj.groupName = (string)row["groupName"]; obj.staffName = (string)row["staffName"]; obj.staffName2 = (string)row["staffName2"]; obj.theDate = (string)row["theDate"]; obj.theEnd = (string)row["theEnd"]; al.Add(obj); } Schedule[] outArray = (Schedule[])al.ToArray(typeof(Schedule)); return outArray; } public class Schedule { public int scheduleID; public string roomName; public string eventType; public string unitName; public string groupName; public string staffName; public string staffName2; public string theDate; public string theEnd; }

The FULL System.Data.SqlDbType reference seems unnecessary? Is there something I am doing wrong or something that should be added to Web.Config? If I try ONLY ",SqlDbType," it will not compile?
MY CODE: SqlParameter AName;
AName = myCommand.Parameters.Add("@AName",System.Data.SqlDbType.VarChar,50);

Hi,
I am getting the following error:
The SqlParameter with ParameterName '@pk' is already contained by another SqlParameterCollection
If I could work out what code to post I would, but I can say that I am managing my Sql data in my code by caching small arrays of SqlParameter objects as pulled from the database. If I need to update the DB I change the cached SqlParameter and re-insert it. If I perform a SELECT I check the cache first to see if I already have the SqlParameter.
However, currently, I am experiencing the above error when performing a select, then later an update, followed by another update.
Would I be correct in saying that a SqlParameter object can only be used once for a database operation and should be discarded? Would I be correct if I said that the SqlCommand object should be discarded? I am barking up the wrong tree entirely?
Distressed in DBLand,
Matt.

Is it possible to have a SqlParameter setup as an Output, and get it to return @@Identity without using a stored procedure?
I have an INSERT statement, written as TEXT in my code (at the time being, I cannot create stored procedures). I'm trying to find out how to return the created IDENTITY that was generated.
Can someone please explain to me how this works?
Thanks.

hi
I am creating a stroed procedure which suppose to update an image column of the given row. I have created the same procedures before which worked fine with texts and numbers but not with Images.
this procedure get table name,row Id, column name of the image, and image data. like:
Create PROCEDURE [dbo].[spImageUpd]
(
@TableName varchar(100),
@Id int,
@ImageColName nvarchar(100),
@ImageData image
)
begin
??????
end
I tryed to use
set @sql='update '+ @TableName+ ' set '+@ImageColName + '=' + @ImageDt' + ' where Id='+ cast(@Id as nvarchar(10))
EXEC sp_executesql
@query = @sql,
@params = N'@ImageDt">N'@ImageDt Image',
@ImageDt = @ImageData
but sp_executesql just accept text as params. is it possible to fix this problem?
thank you in advance

Below I have pasted the error message, hidden form fields, function code and even the stored procedure code. I'd be most grateful if anyone can show me the error of my ways!
Thanks,
theSpike
I'm calling a stored procedure and besides several varchar fields, I'm passing two integer values (employeeID and businessID). These values come from hidden fields on a form and it's the businessID that throws the format error. I call the same stored procedure for both insert and update (the SP evaluates employeeID to decide btwn insert/update) and the insert works perfectly, but the update throws the format exception error. The only difference is that the employeeID is 0 (zero) for an insert and > 0 when it's updating. I strikes me as particularly bizzare that the line that throws the exception is the businessID, not the employeeID because the businessID is the same value for both insert and update. It's the employeeID that is subject to change.
The error:
Exception Details: System.FormatException: Input string was not in a correct format.
Source Error:
Line 147: //businessID
Line 148: SqlParameter businessID = new SqlParameter("@businessID",SqlDbType.Int,4);

Line 150: businessID.Direction = ParameterDirection.Input;
Line 151: theCommand.Parameters.Add(businessID);
I'm calling the SAME function for the insert and update, the same hiddent form fields exist

Hi,
i don't know if this is the right forum to post to, but here i go:
I'm having a problem...
I need to delete several records having as criteria their pk.
The deletion is made using SqlParameter in the code and a stored procedure on server.
as far as i know, i can do this, either using a IN list:
- build and pass the list of id's from code to the sp:
delete from tbl where attachment.id in (1,2,3)
OR
- execute a simple delete several times.
So far i tried first option, but i get errors in converting the list to ints; that is what the sql engine says.
I prefer this option because i think is faster and requires less roundtrips to the sql server.
My questions are:
1. how do i build a sane IN list?
2. is it worth to use a delete in a loop? the records that must be deleted are 5 at most, per job.
1 job can have [0..5] attachments.
Thank you,
Daniel

We've got an app that is in final testing so we can't go around forcing SqlDbType.VarChar. Is there any way to make SqlParameter default to varchar if you don't explicitly set a type for a string value? It's bad for our db index usage because they're all varchar and nvarchar forces a convert_implicit messing up performance.

Hello All,
I'm having a problem tracking down why my app is not instantiating a parameter in a sqldatasource, when I'm expecting it to do so.
When the app fails, this info is displayed:

I've inspected the sqldatasourcecommandeventargs command.parameters in the deleting method during debugging and could not find the parameter in the array, although I "think" it should be because it's explicitly stated in the sqldatasource parameters declarations. I see two parameters in the array, @RETURN_VALUE and @RID, both of which are expected and coincide with the declaration in the stored procedure and the sqldatasource.

Hi,What I am trying to do is to get the new ID for every record is inserted into a table. I have a For...Each statement that does the loop and using the sqldatasource to so the insert. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ myConnectionString%>">

</InsertParameters>
</asp:SqlDataSource> Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim sqlSelect As String
Session("Waste_Profile_Num") = 2
Session("Waste_Profile_Num2") = 5
sqlSelect = "SELECT Range, Concentration, Component_ID FROM Component_Profile WHERE (Waste_Profile_Num = " & Session("Waste_Profile_Num").ToString() & ")"
SqlDataSource1.SelectCommand = sqlSelect

End Sub What I have done so far is to display the new id and I am going to use that return id later. However, the first time through the loop, I am able to get the new id but not the second time. So, I wonder, how do I every single new id each time the INSERT statement is executed?STAN

I am receiving funny results from a query. To simplify, I have 2 tables (todayyesterday). Each tbl has the same 8 columns. My query joins the two tables then looks where either of two columns has changed. What is happening is that when checking one of the columns it seems as though sql is flipping the column, causing it to be returned in error.
result set
colA colB colC colD colE colF colG colG (from yesterday)
1 1 a b c d e m
1 1 a b c d m e
So what's happening is that the record above is actually the same record and should not be returned. There is a daily pmt column that changes but I am not using that in the query. Aside from that the two records are identicle.
Any help is appreciated.

Hi,
I have the following situation (with a site that already works and i cannot modify the database architecture and following CrossRef tables -- you will see what i mean by CrossRef tables below)
I have:
Master table Hotel
table AddressCrossRef (with: RefID = Hotel.ID, RefType = 'Hotel', AddrID)
joins
table Address (key = AddrID)
table MediaCrossRef (with RefID = Hotel.ID, RefType= 'Hotel', MediaID)
joins
table Media (with MediaID,mediaType = 'thumbnail')
foreach hotel, there definitely is a crossRef entry in AddressCrossRef and Address tables respectively (since every hotel has an address)
however not all hotels have thumbnail image
hence i have hotel inner join AddressXReff inner join Address ..... however i must have
left outer join mediaXref left outer join media
the problem is that if there is no entry in Media or mediaXref, I don't get any results
i tried to get over it by using
where (media.mediaTyple like 'thumbnail' or media.mediaType is null)
but then i started getting multiple results for each hotel because media's of type movie or full_image or etc... all got returned
any clue?
thanks

...when I started this endeavor.
I have a previously developed Lotus Notes App. The idea was simple; as
I am sefl taught on Lotus Script, I figured I'd be able to stumble my
way through VB.Well,
it started OK. I used VB Express to get familiar with the stuff, but
decided to go with a full version of VS 2005 and try and get this thing
properly developed as a web app. I purchased several reference books
etc., and have become relatively familiar with the forums here.First
issue I have is that I simply want to use code to update or add records
to an SQL DB. I know about datagridview etc., but I want to update the
DB using forms, not the tabular view those controls provide. I thought
it would be relatively straight forward, but found my ignorance runs
deeper than I thought. When I tried to do so I am finding I am not
really clear on where to make declarations etc. in the web app. If anyone could point me in the right direction that would be great. The
issue with searching these forums is most posts deal with datagridview
or something similar.I have spent a ton of time trying to find relevant
posts or articles, but have had no luck yet.Again, all Ireally
need is a nudge in the right direction. I am more than willing to plod
through reference materials or articles/posts to find what I need to
know, I just can't find where to even start on the info I need. Regards, Joe

Hi,
I'm relatively new to SQL7 but I did use 6.5 a fair bit.
I'm trying to test the restore of the Transaction log backup and having a bit of difficulty. The idea is that I make a complete database backup at 1am backup the transaction log every 30 minutes between 7am and 7pm. I need to be able to restore the database to a known state between 7am and 7pm with a max data loss of 30 minutes.
What I am trying to achieve is (as a test):
1)Create a small test database with a test table
2)Add some data to the test table
3)Back up the transaction log
4)Restore the transaction log to 'undo' the data added in step 2
Should be simple I think !!! The problem I am encountering is that in step 4 it won't let me restore only the transaction log (a tick automatically appears in the database backup as well). Bah !
Can someone please tell me what simple steps are required to get this to work. I need specifically on what options to chose during the backup and restore processes.
Thankyou,
Tim

Given one table with one column and two rows, one containing the string 'Bill', one containing the string 'Gates'.
Write a select statement which gives you the result 'Bill Gates'.
