Using Parameters With An Oracle ODBC Connection?
May 1, 2009I'm connecting succesfully to an Oracle 10g DB with an the Microsoft ODBC for Oracle driver.Regular queries without parameters work fine, but parameterized queries act as if the parameters aren't getting passed in.ex.
--this works fine
Select * from tbl1 where column1 = 'test'
--this doesn't
select * from tbl1 where column1 = ?
--odbc string parameter 'test'
Here's what my connection string looks like:
"Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _

DB/Reporting :: .Net/Oracle Application Best Design When Building Sql Command Parameters
Oct 2, 2009Currently working on a web-service with Oracle10g as back-end. Here is my problem.
1. The table I need to populate has 100 columns. I have no control over the design of the table.
2. I wanted to use the "deriveparameters" method of OracleCommandBuilder, but found out that this is "costly" in terms of performance. What I initially planned to do was to derive the parameters from an open connection, close the connection, then maybe cache the parameters obtained but I don't know if this is possible.
I am unsure how big of a hit the performance will get if I continue using the "deriveparameters" method WITHOUT caching the parameters driven. The environment is as follows
-intranet
-around 2000 users
-users spread out in different parts of the country
I am not familiar where they will put the web pages of the application, the web service and the database. I don't know if they'll be putting it in different servers or on one server, but that's something we cannot control too, that's why I am looking for the best approach.
I just don't want to hard-code all that parameters and if, for instance, we need to change some properties/parameters, it will be a pain to maintain the code. It would be nice if someone here can point a way to automate the whole thing w/o the performance of the system taking a hit.

SQL Select From A Table In An Oracle Database, And Show Results Of Query In VB Application
May 14, 2009I 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.
View 3 RepliesSelect Random Items With Parameters?
Dec 20, 2010I'm working on a program that will randomly select a loadout(weapon, perks, etc), but the user enters their current level to get the loadout. This is important because certain guns unlock at certain levels, so i don't want someone getting something they can't use.
I'm not sure what the best way of approaching this is. All i can think of is either getting a random item, checking if the user's level is high enough then if it's not high enough do it again.

I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:
