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.
View 1 RepliesWhat are the performance or storage implications of using a large value for NVARCHAR? For example, if I specify a NVARCHAR(4000) column just to cope with the rare case there are strings that long, but have a table full of strings 255 characters long, is the performance identical to specifying an NVARCHAR(255) column? Is there a reason then NOT to specify NVARCHAR(4000) on everything? i.e. does the query optimizer use it?
I know how long a row is and how many rows can fit in a page (4096 bytes) affects performance, but my understanding is that NVARCHAR only stores the characters needed so it wouldn't be affected unless there was actually a longer string. I wanted to know if there are any other considerations to using a large value here.
Also, how does NTEXT compare to using NVARCHAR? I noticed the documentation said it used a new page after 256 characters, which sounds like it's different from how a 4000 byte NVARCHAR would be stored?
I'm importing a multi tab spreadsheet using Import wizard, which I understand to use the same internals as SSIS. The total number of columns in the spread sheet will be over 500. The import wizard defaults everything to varchar 255. I understand there is an XML file I can manipulate to change this and they are located
C:Program FilesMicrosoft SQL Server100DTSMappingFiles
Assuming one of these will control Excel defaults, which one is it? None of the names lend themselves to the Excel as a source. SqlClientToMSSql10?
I have a whole bunch of bit fields in an SQL data base, which makes it a little messy to report on.
I thought a nice idea would be to assigne a text string/null value to each bit field and concatenate all of them into a result.
This is the basic logic goes soemthing like this:
select case new_accountant = 1 then 'acct/' end +
case new_advisor = 1 then 'adv/' end +
case new_attorney = 1 then 'atty/' end as String
from new_database
The output would be
Null, acct/, adv/, atty, acct/adv/, acct/atty/... acct/adv/atty/
So far, nothing I have tried has worked.
Any ideas?
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

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

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.

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.

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

I had this question for quite a long time.
It seems the latter one don't take any extra storage space than the previous one.
As long as the real string length is less than 10.
Is that mean the latter one not cost anything?
I once heard the different is when they are in memory. But not sure of it.
Can anyone explain it and provide some official reference on it?
Thank.
How do i know whats the default values on which table and which column and whats the default value
It should be like this

How can i get these results on all the tables in my DB.
Thanks.
I have a 64-bit box with SQL 2000 and 2005 installed on it. At the command prompt, typing BCP -v gives me the 8.0 version, not 9.0. I really want the 9.0 version as the default. Obviously typing

I´m experiencing problems with datepart(weekday,...) function. In particular with week 54 of 2000... (by the way, don´t make a bet about that, because Jan 1st. was saturday (last day of week) and year 2000 was a leap year!!!, so Dec 31 became the one and only case of 54 weeks... in our calendar).
Is there a way I can fix sunday as first day of week, instead using SET DATEFIRST in every procedure? (because "somebody" puts MONDAY as a default in spanish)
Thanx in advance,
César.
I have run the following script to create a default on a table:
alter table TableXYY
add default 0 for ColumnX
Now, how do I delete this default (without re-creating the table)??
Thanks
I'm having some problems when trying to import an external table into my SQL Server 7.0 DB. When date fields are being created the datatype is being set to smalldatetime which is causing errors because some of the data in the source table is using dates proir to 1900.
Is there a way I can set the datatype to be set as datetime instead of smalldatetime?
I have a stored procedure that has @BeginDate and @EndDate as parameters. I created a report with a default for both. They run just fine. After I deployed, I created Linked Reports and wanted to override the defaults. In the defaults, I tried to put in GetDate() for @BeginDate and GetDate()+10 for the @EndDate so this can be passed in the where statement of the stored procedure. I get 'Syntax error converting datetime from character string.'
What I assume is that if I override the default, the stored procedure will process what I put in the @BeginDate and @EndDate parameters.
The where statement looks like:
and (m.BeginDate >= @BeginDate) and (m.EndDate <= @EndDate)
I'm using Reporting Services 2005 and SQL Server 2005.
Thanks, Iris
Does anyone have a way of finding all parameters with default values, for any stored procedure in a database?

I have a column which uses a DEFAULT as GETDATE in one of my tables. When I execute a DTS package to insert data into it, the column values are all the same, but if I use SSIS, the dates differ slightly (by a few ticks after several rows, but not a consistent amount of rows).
Is there an explanation for this difference, and how can I correct this problem?
I have a table, tbl1:create table tbl1 ([field1] [char] (16) NULL DEFAULT (' '),[field2] [char] (6) NULL DEFAULT (' ')).When I do a select * into tbl2 from tbl1, tbl2 does not have defaults.Is there any settings I have to keep on when I do a select * into?Any help will be appreciated.

Thanks in advance for fielding my question!
I have parameters (type=datetime) on a report whose values are populated from a query. This query just pulls a list of all the dates (all Sunday dates) in a table. I have the parameter set up to have the date as the value and then a string representation of the value as the label (ie 2007-11-25) to make it easier for the user.
I want to set up a default for this parameter that essentially takes today's date and calculates the previous Sunday's date so the parameter drop down defaults to last Sunday's date.
My expression works fine just to display it on the report in a text box. It calculates and displays last Sunday's date perfectly. BUT, it doesn't work when I use it in the expression for the parameter default - Im' assuming because the latter cares about data type?
here's my statement:
=Iif(Now.DayofWeek=1,dateadd("d",-1,Now),(Iif(Now.DayofWeek=2,dateadd("d",-2,Now),(Iif(Now.DayofWeek=3,dateadd("d",-3,Now),(Iif(Now.DayofWeek=4,dateadd("d",-4,Now),(Iif(Now.DayofWeek=5,dateadd("d",-5,Now),(Iif(Now.DayofWeek=6,dateadd("d",-6,Now),(Iif(Now.DayofWeek=7,Now,0)))))))))))))
In short all those if statements calculate the day of last Sunday's date based on Now()...so if it's Monday, subtract 1, if it's Tuesday, subtract 2...etc.... BUT this returns the time also - argh! Formats!
How can I format this so it will equate to my oracle date populating in my parameter list? Do I need to match the output of the above statement to the LABEL (ie, string) or the actual VALUE (ie, date). I've tried both. I've hacked at this thing for an hour and I'm sure it's so obvious!
Thanks!

Hi guys,
I have a problem when configuring SharePoint and RS on two boxes. (If install everything in one box is fine)
I have SQL SP2 + RS in one server and SharePoint on the other server. I've followed every step in the SQL 2005 Online Book to configure the RS and SharePoint including:
How to: Install the Windows SharePoint Services Object Model on a Report Server Computer. (Done)
How to: Configure Service Accounts (Reporting Services Configuration). (Done)
However, I got an error when click "Set server defaults" in SharePoint Central Admin:
An unexpected error occurred while connecting to the report server. Verify that the report server is available and configured for SharePoint integrated mode.
In ReadMe of SQL SP2, see below: http://download.microsoft.com/download/f/d/c/fdcb3a53-0cb1-4e67-a1b6-45b89b3c59cf/readme_rsaddin.htm#_rsshare_known_problems_7

6.4 Service account requirements for Reporting Services
Restrictions on using built-in accounts apply to some deployment topologies of Reporting Services that include a report server running in SharePoint integrated mode. The following combination of factors will result in service account requirements:
The report server is integrated with a SharePoint farm comprising more than one computer.
The report server and SharePoint Central Administration Web site run on separate computers.
In this scenario, if either the Report Server Web service or Windows service runs under a built-in account such as NetworkService, the Grant database access option in SharePoint Central Administration will not work correctly. Consequently, accessing any Reporting Services feature through a SharePoint site will result in the following error:
"An unexpected error occurred while connecting to the report server. Verify that the report server is available and configured for SharePoint integrated mode. --> Server was unable to process request. --> Client found response content type of 'text/html; charset=utf-8', but expected 'text.xml'."
To avoid this error, choose one of the following approaches:
On the computer that hosts the report server, continue to run the Report Server Web service as NetworkService and add the built-in account, such as NT_AUTHORITYNetworkService to the WSS_WPG Windows group.
Configure the service accounts to run under a domain user account as follows:
Start the Reporting Services Configuration tool and connect to the report server.
Click Windows Service Identity, click Windows Account, type a domain user account, and click Apply.
Click Web Service Identity, for Report Server, click New, type an application pool name, click Windows Account, type a domain user account, and click Apply.
Reset IIS.
Restart the Windows service.

I did try it out but still get the error when clicking "Set server defaults" link in SharePoint Central Admin.
Is there something wrong with the two boxes installation???
Hope the MS guys can help.
