Query SQL Server Table Results Into A List?

Apr 13, 2012

I am trying to create a CLR SQL Stored procedure that uses a query and adds the results to a list in VB.NET. Through debugging I determined that my add statement for the reader into the List is somehow converting my data types and throwing an error when I attempt to execute the compiled Stored Procedure.The columns I am querying are Integers

Code:
Imports System
Imports System.Data

Populating A List Box With Query Results?

Dec 9, 2009

I am working on making a Windows based application within Visual Basic 2008 Express that could potentially be used for a music school as a project. This application is connected and bound to a Microsoft Access database. Within this application I have a form for adding a new appointment reservation. This form has a combo box that the user can select the lesson type (eg. "I want a piano lesson"). Upon being changed, a list box would be populated with the names of all instructors that have that selection as either their primary or secondary talent.So, my database is bound, the query is written (correctly...i hope), and I don't know how to 1) select the table column that I want displayed in the list box and 2) actually display the query results within the list box. Is this making sense? Probably not, bu

Private Sub cmbLessonType_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmbLessonType.TextChanged

SQL Select From A Table In An Oracle Database, And Show Results Of Query In VB Application

May 14, 2009

I want to (SQL) select from a table in an Oracle database, and show the results of the query in the VB application, in a Excel like manner (rows, columns, selectable, etc.). Or in a SQL developer manner. How can I do that? Browsed through a lot of tutorials and howtos on the internet, did not get anywhere. I think (and correct me if I am wrong) that it's gotta be something with DataGridView. But I don't know how to create and populate a datatable with the result of as Select statement, how to create a dataset.

SQL Server 2005 - Select From Multiple DB's & Compile Results As Single Query?

Sep 25, 2009

Ok, the basic situation: Due to a few mixed up starts, a project ends up with not one, but three separate databases, each containing a portion of the overall project data. All three databases are the same, it's just that, say 10% of the project was run into the first, then a new DB was made due to a code update and 15% of the project was run into the new one, then another code change required another new database for the rest of the project. Again, the pertinent tables are all exactly the same across all three databases.

Now, assume I wanted to take all three of those databases - bearing in mind that they can't just be compiled into a single databases due to Primary Key issues and so on - and run a single query that would look through all three of them, select a given set of data from each, then compile those three sets into one single result and return it to the reporting page I'm working on.

When Save results In A SQL Server Table / They Are Incorrect

Mar 10, 2009

When subtracting two doubles the result appears to be correct but when I save said results in a SQL Server table they are incorrect. I know their are problems with decimal values in the binary world but isn't there a work around for this?For example 421.2 - 418.9 = 2.3, but the result stored in the SQL Server table is 2.29!In the VB code I used Math.Round to round to two digits and the values appear correct during debugging but, as I've said, in the end they are off by .01. [code] decimal(10,2)BTW, I've tried numerous methods of getting the correct value but have not met with any success. I've used Math.Round on Val1 and Val2 separately, after the subtraction, and on the ResultVal. I've also converted the ResultVal to a string using Format(ResultVal, "#####.00") and then back to a number but still the value that ends up in the SQL Server table is wrong.

Database Table Attributes - Query A List Of Table Names In The Database Ordered By Date Created

Jan 22, 2011

[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?

Multi - Table Join Query In ASP.NET To SQL Server Via LINQ?

Jan 29, 2012

I'm working on an ASP.NET 4.0 site, which I inherited ownership of. It has a number of existing LINQ datasources pointing to individual tables. For example, to the Patient Encounter Summary table in SQL Server. The problem is in displaying the data there. It's a normalized database, so that table contains (for example) the provider ID, rather than the provider name.

It's simple enough to join the Patient Counter Summary to the Providers table (in SQL)... but how does one do that in ASP.NET? I'm not sure of the correct nomenclature, but the 'mid layer' is VB.

If this is in the wrong section, I have a program that queries a database and puts the info in a specific format in a txt file. Now my problem comes w/ how to format the date.

Should I format the date in the SQL query OR is there a way to take the result from the query and format sometime before it is writen to the txt file? I'm not exactly sure how to do either. Would I need a subquery to get the desired date format?

I think probably the biggest help would be an explaination of what the code in bold is actually doing. I pulled this from a book but don't think I completely understand. To me it seems like its saying that for each row in table 'extract'. Extract it, and write it?? But it doesn't seem to work that way. When it gets to that part, the error I get says that the row doesn't exist in the table

Asp.net - No Results From Oracle Query In VB ASPX?

Jul 10, 2009

Why would a VB/ASPX page not return results for a query which runs fine with other Oracle clients? (Same username) The following code should first output the query and then execute it outputting a single exclamation point per record. However, it outputs the query (as it should), but does not return any rows (nor error). If I copy the query to SQL Plus (or other editor) as the same user, the query returns results.

Why might my code not output any results?

Dim MyQuery As String = "...some query..."
Dim Factory As DbProviderFactory = DbProviderFactories.GetFactory("System.Data.OracleClient")
Dim myConn As DbConnection = Factory.CreateConnection
Dim myCommand As DbCommand = Factory.CreateCommand
Dim MyReader As DbDataReader
