I have a DataGridView which populates from an SQL query just fine in default mode
using these table names
[firstName] [varchar](20) NOT NULL,
[lastName] [varchar](20) NOT NULL,
[code]....
I have edited the column headers and set the column names to the same values as my table names yet the data is not showing in form load I have set datagridview.AutoGenerateColumns = False I know the data is there if I delete datagridview.AutoGenerateColumns = False then the data is shown with the default headings?
SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

View 1 RepliesSo hopefully this is a quick fix but for the life of me I can't figure out how to get my results from a OracleDataReader record set.Just trying to get all the users for a specific TNS into an array. I was able to do this easily before with ADODB, but thought I would try using ODP.net.Here is what I have so far and it definitely gets all the USERs for a given TNS. its when I get to the READ() part where the syntax is ??
View 1 RepliesRelatively new to VB.NET coding. Am creating a pretty simple console application that needs to insert over 50,000 records into an Oracle table (OleDB connection). I tried 3 different methods so far: Individual INSERT, insert using a dataset, & using INSERT ALL (commit every 25 records due to # of columns). It seemed like most articles/posts I read recommended the dataset approach, but the INSERT ALL code was definitely the fastest by far.

I have a VB.Net application that populates an Oracle 11g global temporary table. I can see data in the temporary table by loading it into a grid and everything looks correct.However, when I call an Oracle stored procedure from VB.Net that would manipulate the data in this temporary table, the stored procedure reports that my temporary table is empty.I understood that data in an Oracle global temporary table should be visible to all sessions.

View 3 Replies[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?
View 6 RepliesI am trying to export an excel file directory into an Oracle table as opposed to looping through the range and executing a lot of insert statements. I would think that there are better ways to accomplish this in .NET but I can't seem to find any other answer besides convert excel to csv & load it using Sql Loader or External Table. Does anyone know a cleaner & more efficient way that looping through the ranges creating & executing insert statements?

View 3 RepliesI 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.

So instead of it being two separate combo boxes with both last_name and first_name), it want it to find the the names with first and last name in the same combo box.
