SQL Server Fields And Sqlparameters

Nov 7, 2005

I am setting up a database and I would like to insert fields using sqlparameters into the database.  What I need to know is the relation between sqlparameter size and db field 'length' field.IE:  In the database does the 'length' field indicate bits? (which means that you have to convert parameter to bytes?)and what does the 8 refer to below?<CODE>Dim Param2 As New SqlClient.SqlParameter("@flTest", SqlDbType.VarChar)Param2.Size = 8</CODE>Thanks,Joe

Looping Through Sqlparameters

Apr 11, 2008

lets say i have a stored procedure (for insert command) which i am calling in my code to execute.  The user provided data is being stored in a array. My class takes the stored procedure name and also takes parameters name and types.  Is there any way to loop through the parameters,  (various columns in the table which is of diffrent data type ie varchar, int, etc).  How to implement it?

SqlParameters Not Working With Stored Procedures

Dec 31, 2006

Anyone can help me why is this not working?
My function is
public void updateSupplierInformation(string FirstLetter, string Vendor, string SegmentTeam, string VendorRank, string ScrubOwner)
{
SqlCommand myCommand = new SqlCommand("sp_LAST_UpdateSupplier", myConnection);
 
myCommand.CommandType = CommandType.StoredProcedure;
myConnection.Open();
SqlParameter myParam;
myParam = myCommand.Parameters.Add(new SqlParameter("@FirstLetterS", SqlDbType.VarChar, 1));
myParam.Direction = ParameterDirection.Input;
myParam.Value = FirstLetter;
myParam = myCommand.Parameters.Add(new SqlParameter("@VendorS", SqlDbType.VarChar, 30));
myParam.Direction = ParameterDirection.Input;
myParam.Value = Vendor;
myParam = myCommand.Parameters.Add(new SqlParameter("@SegTeamS", SqlDbType.VarChar, 30));
myParam.Direction = ParameterDirection.Input;
myParam.Value = SegmentTeam;
myParam = myCommand.Parameters.Add(new SqlParameter("@VendorRankS", SqlDbType.VarChar, 30));
myParam.Direction = ParameterDirection.Input;
myParam.Value = VendorRank;
myParam = myCommand.Parameters.Add(new SqlParameter("@ScrubOwnerS", SqlDbType.VarChar, 30));
myParam.Direction = ParameterDirection.Input;
myParam.Value = ScrubOwner;
 
int i =myCommand.ExecuteNonQuery();
 
myConnection.Close();
}
My Stored procedure is:
ALTER PROCEDURE sp_LAST_UpdateSupplier
@FirstLetterS varchar(1),
@VendorS varchar(30),
@SegTeamS varchar(30),
@VendorRankS varchar(30),
@ScrubOwnerS varchar(30)
AS
UPDATE [gntm_user].LAST_Supplier_Ownership
SET First_Letter =@FirstLetterS,Seg_Team =@SegTeamS,Vendor_Rank =@VendorRankS,
Scrub_Owner =@ScrubOwnerS
WHERE Vendor=@VendorS
 
RETURN
 
When I debug on any of the myParam value it displays "@FirstLetterS,@VendorS" etc. not the value which is being passed in the function which is FirstLetter,Vendor.
Can anyone help me on this please? Thanks in advance

SqlParameters From Dynamically Loaded Assembly Won't Work!

May 13, 2004

Hi there!

I was trying to dynamically load a custom WebControl and display it into my WebFrom.

WebControl is loaded by:

System.Reflection.Assembly assembly = System.Reflection.Assembly.Load("myAssemblyName");
Control module = (Control)Activator.CreateInstance( assembly.GetType("myClassName") );
ModulePlaceHolder.Controls.Add(module);

This is working fine. Assembly is loaded and WebControl is created.

But as my Custom WebControl tries to access SQL Server database, i get a "Must declare the variable '@id'" while executing an ExecuteScalar() from a SqlCommand.

Code in my WebControl was perferctly functioning before converting it from a UserControl (.ascx) to Custom WebControl. Parameter '@id' is correctly declared in my query. If i don't use SqlParameters, everithing works fine...

Any ideas??

Thank you so much!!!

Bye!

Using Membership UserId Guids With SqlParameters (Membership UserId Guid)

May 7, 2008

In my site, when a user registers, I need to create rows in additional tables besides aspnet_Users. So, I need to be able to pass the generated userId guid to subsequent SqlCommands. I'm having a terrible time with this. What's the correct way to set up a SqlParameter so that it will accept a guid? I keep getting this error: "Conversion failed when converting from a character string to uniqueidentifier."
I've tried creating the parameter both with and without a SqlDbType.
cmd.Parameters.AddWithValue(paramName, guid);
and
SqlParameter p = new SqlParameter(paramName);p.SqlDbType = SqlDbType.Guid;cmd.Parameters.Add(p);
and I get the same error either way.
Driving me nuts! Any help appreciated.

Subreports: Parameter Value Dropdown Shows Sum And Count Fields But Not The Actual Data Fields.

Jan 28, 2008


I have just started using SQL Server reporting services and am stuck with creating subreports.

I have a added a sub report to the main report. When I right click on the sub report, go to properties -> Parameters, and click on the dropdown for Parameter Value, I see all Sum and Count fields but not the data fields.

For example, In the dropdownlist for the Parameter value, I see Sum(Fields!TASK_ID.Value, "AppTest"), Count(Fields!TASK_NAME.Value, "CammpTest") but not Fields!TASK_NAME.Value, Fields!TASK_ID.Value which are the fields retrieved from the dataset assigned to the subreport.

When I manually change the parameter value to Fields!TASK_ID.Value, and try to preview the report, I get Error: Subreport could not be shown. I have no idea what the underlying issue is but am guessing that it's because the field - Fields!TASK_ID.Value is not in the dropdown but am trying to link the main report and sub report with this field.

Am I missing something here? Any help is appreciated.

Thanks,
Sirisha

Transact SQL :: Get One Row From Multiple Based On Fields And Also Get Sum Of Decimal Fields?

Jul 2, 2015

I am using MS SQL 2012.  I have a table that contains all the data that I need, but I need to summarize the data and also add up decimal fields while at it.  Then I need a total of those added decimal fields. My data is like this:

I have Providers, a unique ID that Providers will have multiples of, and then decimal fields. Here are my fields:

ID, provider_name, uniq_id, total_spent, total_earned

Here is sample data:

1, Harbor, A07B8, 500.00, 1200.00
2, Harbor, A07B8, 400.00, 800.00
3, Harbor, B01C8, 600.00, 700.00
4, Harbor, B01C8, 300.00, 1100,00
5, LifeLine, L01D8, 700.00, 1300.00
6, LifeLine, L01D8, 200.00, 800.00

I need the results to be just 3 lines:

Harbor, A07B8, 900.00, 2000.00
Harbor, B01C8, 900.00, 1800.00
LifeLine, L01D8, 900.00, 2100.00

But then I would need the totals for the Provider, so:

Harbor, 1800.00, 3800.00

Update Fields With Data From Other Fields In Same Row

Jun 30, 2000

Pardon me if this question is too elementary. I am trying to create a trigger that will cause certain datafields to be updated with values from other data fields in the same row when a certain column, created specifically to fire the trigger, is updated. The purpose of this is to reduce data entry by field personnel.I think I have the create trigger statement correct, but I'm a little confused on the update statement.

In a nutshell, how can I write something like:
UPDATE "TABLENAME"
SET DATAFIELD1 = DATAFIELD2
WHERE RECORDNUMBER = (THE SAME RECORD NUMBER)

I do know that I have to ensure that sp_dboption Recursive Triggers value is set to false, thanks.

Using LIKE To Find Any Of Fields In One Table In Fields Of Another

Jul 31, 2013

I have a list of items in one table and a field (pageName) in another table that may contain one of the aforementioned items somewhere within that field. There is no fixed position within the field where the itemNo may be so I can't just use SUBSTRING(pageName,2,5) in(select itemNo from tblItem).

Logically, it's like I need to combine IN and LIKE: select pageName where pageName LIKE IN %select itemNo from tblitemNo%..LIKE can only handle one comparison string.

Drillthrough In Calculated Fields Enable When Drillthrough Option Is Disable In Original Fields, Is This A BUG?

Jan 21, 2008

Hi people
My users are having troubles with link to default drillthrough report when reports are exported to excel (they REALLY don't like this behavior ), so I decided set all of them disabled in report model, this work fine, but calculated field in reports has this drillthrough link.


Let me show you the situation. Entity Product has an UnitaryCost field, I set the EnableDrillthrough Property in False so when I export a report with this field, no link is shown.

But if I create in the report a calculated field Round(UnitaryCost) this field has a Drillthrough Link

Is this the standard and expected behavior? or its simply a BUG?

Have I done something wrong in my model? and in this case, How I can correct this?

regards.
Julio Diaz.

SQL Server Text Fields

Mar 16, 2006

The Text datatype can hold several million characters
The size of a record can be no more than 8 KB in normal data.

Created a table with one text field. For some reason can only store 1K of data into it. Even if the 8K limit was a factor (which it shouldn't for a text field) I cannot add more than 1K of data into my text field. 1023 characters to be exact.

Why is SQL Server 2000 doing this and more importantly how to resolve?

Inserting Blank Fields Into Sql Server

Apr 13, 2007

when inserting or updating fields in sql server and the field is blank sql still adds several spaces into the field.  Then if I try to check whether a field is empty or not for display I get incorrect results because fields that should be empty have 2 or 3 spaces in them instead and therefor aren't selected as being empty.  Is there any way around this? to force the fields to be saved as blanks or null?

Identity Fields As Primary Key In Server 7.0

May 13, 1999

Most of the tables in my database are implemented with IDENTITY columns as the primary key.
When an INSERT from my application is attempted, sometimes I get an error returned stating that insert
cannot be done because of duplicate key value. If I try the INSERT again, sometimes it works(??). Of course,
DBCC CHECKIDENT resets the identity value if trying the INSERT again doesn't work. Then sometime a little later, the problem happens again.
Is there anything I can do other than placing into my application code the execution of dbcc checkident
anytime I want to do an insert to prevent the error? By the way, DBCC CHECKDB revealed no problems.

HELP!

Getting The Latest Data From Different Fields In One SQL - SQL Server 2000

Aug 9, 2006

Hi,

I'm trying to write some SQL which will give me the following result from the table below..

Currently I can do each of the PRICEx fields in a seperate query then join the results together. I do this by getting the MAX(Date) WHERE PRICEx IS NOT NULL then using that date to get PRICEx, and then repeat until I've done all the PRICE fields.

This is acceptable for a small selection, but for a large selection this can get quite slow. I was just wondering if there is there a way to do this in one single SQL without having to join the table to itself 3 times (for all 3 PRICE fields)







Source Table:





ProductID
MarketID
Date
PRICE1
PRICE2
PRICE3

1
2
1/01/2006
2.45
3.4
2.97

1
2
2/01/2006
2.51
3.5
NULL

1
2
3/01/2006
NULL
3.6
NULL

1
2
4/01/2006
NULL
NULL
NULL

Result:



ProductID

PRICE1
PRICE2
PRICE3

2.51
3.6
2.97

Is There A Way To Simply Programticly Create A SQL Server Table And All The Fields?

Mar 26, 2008

I am developing a asp.net app and I have a long, very long list of data fields.
The values of the data fields have to be saved to a SQL database. The list is so long that it a pain in the ass to have to write all the code even to declare an object and all its properties by hand. So...
I made a list of all the field names and types and load it all up in an array. Then I wrote a bunch of macros to write all the properties one by one with the corredt type for the object I needed to create instead of doing it all one by one by hand.
I want to do the same thing with the Database. I dont want to have to hand define all the fiedls 1 by 1 by hand in the IDE. I want to write a simple macro, a loop theat loops thru my array and creates a field with the field name and type that it says in the array.
Simple enough.. Now I have the table defined already since that was simple enough. It is the 200 ++ fields that I dont wanna do.
So, please what is the code I need (in VB) to create 1 simple field in an existing table. Say the table is called "Table1" in the database "Database1" and the field I want is to be called "Field1" and to be 250 chr string..... ???
 Thank you Marc

When Submitting Form, SQL Server Fields Only Show The First Letter

Nov 30, 2005

Hi, I'm new around here and am stumped.  I have created a form where I submit the information into a SQL Server 2000 table.  When I submit the information through the form, only the first character of each field populates inside of the SQL table.  This happens for every field except for two, zip and comments.  The zip field is numeric and the comments field is text.  All the other fields are varchar fields; and these are the fields with the problems.  I have attempted to change the data type to text, but that did not work either.  I am doing this through a stored procedure I created.  Here is the asp code:
Public Class WebForm1
Inherits System.Web.UI.Page
Protected WithEvents txtFirstName As System.Web.UI.WebControls.TextBox
Protected WithEvents txtLastName As System.Web.UI.WebControls.TextBox
Protected WithEvents txtAddress1 As System.Web.UI.WebControls.TextBox
Protected WithEvents txtAddress2 As System.Web.UI.WebControls.TextBox
Protected WithEvents txtCity As System.Web.UI.WebControls.TextBox
Protected WithEvents txtZip As System.Web.UI.WebControls.TextBox
Protected WithEvents txtEmail As System.Web.UI.WebControls.TextBox
Protected WithEvents txtPhone As System.Web.UI.WebControls.TextBox
Protected WithEvents txtComments As System.Web.UI.WebControls.TextBox
Protected WithEvents ddlState As System.Web.UI.WebControls.DropDownList
Protected WithEvents ddlGift1 As System.Web.UI.WebControls.DropDownList
Protected WithEvents ddlGift2 As System.Web.UI.WebControls.DropDownList
Protected WithEvents ddlGift3 As System.Web.UI.WebControls.DropDownList
