DataSource Controls :: Take Names From The Table And Do Another Select Based On That List Of Names?

Jun 1, 2010

I have been working with this database for some time. Here is the situation...

I inherited a MS SQL database that has hundreds of tables with similar data. For instance:

FordTampa_customer is a table,

ChevyAtlanta_customer is a table, etc....

All of the columns are the same...just different tables with their own ID field. All I have done...Inside of another database id is created a table called 'Customer' and added an 'Dealer ID' column along with the rest of the other columns in the other tables...

So the combination of the 'Dealer ID' and the 'ID' field are unique.....I know...its not the best way to do things...but I cannot change the old data structure because I cannot have access to it. I am give back-ups on a weekly basis, so this is all I have to work with.

All right, on to the real point of my post...

Currently, I have an application that I use to select all of the data from the 'Ford_customers','Chevy_customers',etc... and inserts them into my new main 'Customer' table. I do this by selecting the table names, bind it to an arraylist, loop through the list and execute an insert statement.

I do this in VB.NET, but I would prefer to do it in a Stored procedure of some kind....I just am not sure how to accomplish it. I use this syntax to get my list of tables:

[Code]....

I am not sure how to take those names from the table and do another select based on that list of names.

Forms Data Controls :: How To Get Gridview Field Names

Jan 17, 2011

I have a gridview that is dynamically created based off a csv file I'm importing.

Since I don't know what the column names are ahead of time, I can't pre format the gridview and use the "findcontrol" method to get the text value of the labels that are populated b/c I don't know the column names.

I know I can get the row index like this by iterating through the gridview...

[Code]....

but I'm not sure how to get the text value of the first column label? Not sure of the syntax?

C# - How To Use Lambda Expression To Select Different Fields From Field Names

Nov 18, 2010

I need to get two fields from a database table (retrieved using linq-to-sql), one field is a datetime (and is a fixed field) and the other is always a decimal, but the field can be different.

The table holds currency data which is processed twice a day and in different currencies so could have fields such as AM_USD, PM_USD, AM_EUR etc. And I need to get data such as a list of the date against PM_USD or the date against AM_EUR.

I would like to be able to call the data using a lambda expression for example (this is a stripped out example):

data = TableData.Select(x=>new {x.DateTimeAdded, x.[**field name as string**]});

I have been trying to write a function to do this, and am failing dismally.

The closest I have managed is:

private Func<TableData, KeyValuePair<DateTime, decimal>> CreateSelect(string FieldName)
{
var parameterExp = Expression.Parameter(typeof(TableData), "sel");
var dateParameter = Expression.Parameter(typeof(DateTime), "DateTimeAdded");
var fieldParameter = Expression.Parameter(typeof(decimal), FieldName);
ConstructorInfo constructorInfo = typeof(KeyValuePair<DateTime, decimal>).GetConstructor(new[] { typeof(DateTime), typeof(decimal) });
NewExpression constructExpression = Expression.New(constructorInfo, new ParameterExpression[] { dateParameter, fieldParameter});
var lambda = Expression.Lambda<Func<TableData, KeyValuePair<DateTime, decimal>>>( constructExpression, parameterExp);
return lambda.Compile();
}

Which fails with "System.InvalidOperationException: Lambda Parameter not in scope".

I'm sure I missing something obvious, or going about it wrong way.

ADO.NET :: How To Replace The Field Names In SQL Query String With Variables

Aug 17, 2010

How can I replace the field names in sql query string with variables like:-

string field1="ID";
string field2="Name";
sql = "Insert into [Sheet1$] ('" + field1 + "','" + field2 + "') values('1','abc')";

I am inserting data into an Excel document which has got nearly 100 columns.

I am inserting data using OLEDB as follows:-

System.Data.OleDb.OleDbConnection MyConnection ;
System.Data.OleDb.OleDbCommand myCommand = new System.Data.OleDb.OleDbCommand();
string sql = null;
MyConnection = new System.Data.OleDb.OleDbConnection(connectionstring);
MyConnection.Open();
myCommand.Connection = MyConnection;
sql = "Insert into [Sheet1$] (ID,Name) values('1','abc')";
myCommand.CommandText = sql;
myCommand.ExecuteNonQuery();
MyConnection.Close();

I want to specify the field names at runtime as mentioned above - sql = "Insert into [Sheet1$] ('" + field1 + "','" + field2 + "') values('1','abc')"; When I try this I am getting error.

How To Determine Corresponding Field Names Of Items In Request.Files

Sep 15, 2010

Given a set of uploaded files in Request.Files, how do figure out which form field yielded which file?

I have a generic form emailer that various forms post to. This file generates an email of the name/value pairs contained in the form post. I'm trying to add support for uploaded files such that the table of name/value pairs will show the name of the file upload element and the name that the file was saved as.

However, I can't figure out how to link that information together. HttpPostedFile doesn't contain any information about the HTTP request (like which field name was used), and Request.Form doesn't contain any entries for uploaded files.

So while I can easily upload the files, I don't have an easy way to generate an email saying "this uploaded file was for this field, and this uploaded file was for that field".

DataSource Controls :: Storing Required Field Names In Web.config?

Feb 2, 2010

I am writing an app that has a bit of process flow to it. On the save of a record, I need to check some fields to make sure they are not null. If they are not null, I will update a 'SectionComplete' field to true.

The thing is, I would like to store my fields in the web.config. So, I would like to have a string in the appsettings section that has a list of field names that are required. Then in my method, I would call these fields out and check each one for the specific record id, and then update the database.

I would like to do this in the web.config so we could add/remove columns without having to redeploy.

For example: my required fields are name, id, and phone. For section one to be labeled complete, all of these fields would need to be not null.

web.config would have this entry:

<add key="Stage1Fields" value="name, id, phone"/>

Web Forms :: Trying To Create A Custom Control That Has A Dropdown List And A Required Field Validator In It?

Jan 19, 2011

I'm trying to create a custom control that has a dropdown list and a required field validator in it.I've got as a far as being able to set the error message if the control fails to validate, but I can't actually get it to validate, not can I figure out how to call a .Validate method server side. This is driving me nuts!
To create my control, I followed the article here I ran the text box example through, and I can get that to validate without any problems, so I then went through and created a new set of class files relating to a drop down list.Anyone got any thoughts, or hints as to what might be wrong, or where I should start looking?
