For the last couple of days I've been having problems inserting data into my MySQL database. I'm using parameters to insert the data and have done so in the past without any problems, but for some reason I haven't been able to get it to work this time.I have a form that the user inputs data to be inserted into the database. This data is then pushed into an array and sent to my class (CastProduction.VB) via a Public Sub. The data than pushed into a datarow and than pushed into a datatable. Once this is done I send the dataset and sql insert statement to a private sub that inserts the data into the database.
DELIMITER $$ CREATE DEFINER=`root`@`%` PROCEDURE `Check1`( IN P_Name VARCHAR(50) ,OUT P_Id INT
[code]....
as various columns I need use VB .Net to call this procedure, insert value into the database and get the ID (primary key - company ID).Whenever I insert a row, I need to retrieve the ID. Right now, I am able only to insert the row, but don't know how to call a SP with both input and output parameters from VB.
Let's say I have a MySql stored procedure that inserts a record with some nullable CHAR fields. In VB.NET if I don't check for Nothing (or Null in other languages), I get an exception from the db driver, so I write: command.CommandType = CommandType.StoredProcedure; command.Parameters.AddWithValue("_name", if(name Is Nothing, "", name)).Direction = ParameterDirection.Input;
And this is the first thing I don't like; I'd like to pass Nothing and the driver knows it has to put NULL in the Db. But then, in the stored procedure, I have to check back the field if it is empty: INSERT INTO mytable (name, -- other 200 char fields) VALUES (NULLIF(_name, ''), -- other 200 char fields )
I have to check for nothingness/emptiness twice. Is there a better, more direct, way? Even worse, for non reference types (i.e: Integers) the check for nothingness makes no sense, since a primitive type can't be nothing (yes, I could set an Integer to a non meaningful value, say -1 for a positive id, but...).
I'm learning about VB.Net and need to work with an SQLite database using the open-source System.Data.SQLite ADO.Net solution.The examples I found in the HOWTO section are only in C#. Would someone have a simple example in VB.Net that I could study to understand how to use transactions when INSERTing multiple parameters?[code]
What is the preferred method of adding the current date/time into an SQL Server table with INSERT Command and executenonquery? I'm expecting something like ...
I have been posting almost 4 questions now where I have received 2 answers being solved. These are simple questions which any one familar with VB.Net can solve easily. Please understand, I'm a newbie to VB.Net.
Now my next issue is; I have a a form which has text boxes from where the user has to enter the data for the MS Access backend. I am getting the error as INSERT SYNTAX Error when entering the data and clicking the Save button. What is wrong with my insert statemnet below which is at the click even of the Save button?I desperately need to get this application working.
I have a form named status and from here I want to add a new record in the first table (stats).I've created the insert statement in the first table which is running well, but I don't know how to get the last_insert_id from stats table and insert it in the second table stats_det.
I have been using the internet to figure out how to INSERT into MySQL database. Im almost there I can feel it. Below is the code I put together, but when I click on the button and check the database to see if the data was inserted, it has not.
Imports System.Data.Odbc Imports System Public Class Form1
I have been disturbed for a week now. I have a project in vb.net. And on forms I have two masked text boxes. One is for the user to enter their date of birth and in the second one Iam trying to get the date the record is created. With this one I get the current date from pc and format it to dd/mm/yyyy because I want the user to understand the date. How do I INSERT the user date of birth and the the Now () date which is also in masked text box into a MYSQL database? I know how to insert other text but the date fails to appear in database.

I'm trying to do a looped insert using the MySQL Connector for .NET and for the most part it's working, except for it's missing out inserts. The code below is what i'm using. An example is there are 20 items in the listview and only 8 out of the list actually insert to the mysql database. It's as if the loop runs too quickly for MySQL to keep up. My issue is that eventually this loop will be inserting many thousands of entries and I can't have it missing information out.
I have this code and whenever i try to run it, I always get an ODBCEXCEPTION WAS UNHANDLED ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.0.51b-community-nt]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'char VALUES('101','noodles')' at line 1
I am trying to to an insert query on my MySql db using VS 2008/VB. I have this query: Insert into allservices StartDate....) values ('" & Me.datesched.Value & "', ....) When I use the single and double quotes, as it is above , I get this error: Quote: Incorrect date value '21/10/2009' for column StartDate at row 1
when I remove the single quotes and have only the double ones I get a completely different thing. The date inserted to the database is 01/01/0001. Even if my datetimepicker has a min and max date. Also if someone has any good links on using mysql with vb.net
I want to insert image in mysql database using my vb.net program. Then my php script should be able to read from that database and create a file which can be viewed/downloaded by me.Now I am using vb.net program to connect and insert rec in db.

I am developing a portion of an application that deals with settings reminders and alarms for personal notes. I am trying to insert from a formatted datetimepicker( formatted to show time only ) the time a user wants to get a reminder of something he/she wants. The column in the MySql database is of type 'Time'. I was never succesfull in entering and saving the data. Either I was getting validation problems not allowing me to exit the datetimepicker after I choose the time. To resolve this issues I just made 'false' the option 'causes validation'. Now the problem is that the time is not inserted getting problems saying that :
Quote: Specified cast is not valid.Couldn't store <01/01/1753 00:00:00> in ntime Column. Expected type is TimeSpan.
here is the code for saving
Dim xtime As DateTime = New DateTime xtime = Me.NtimeDateTimePicker.Value Dim result As DialogResult
[code]....
This time it does not even insert a new row it just updates the last entry I have changing its time. This is strange as this happens only when I use the above two lines.
