View 1 RepliesI have this MySQL Query glitch in my VB.NET program. Here is the query in VB.NET:
"SELECT Points FROM user WHERE Username = '" & UsernameText.Text & "';"
It will select the points column from the user table from the Username they entered. When I deploy this it will set the value for points to 0 on their account. I'm not even inserting anything in.
I have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?
I have a problem inserting data into a table on a MySQL database using a VB.NET application. I have a simple form where when I set some data to the textboxes and I press a GO button, the code should execute a function called InsertCar() that takes all these values and insert them into the database and then return true if the transaction is done successfully or false otherwise. My problem is that nothing is being inserted into the table.

View 14 RepliesI want to connect to Sage Data, to the stock table, and select certain columns such as SKU, title, description, sales price and then select the rows I want and send these to an excel spreadsheet formatted in the style required for upload as product feeds to google shopping, shopzilla, amazon and Ebay etc.Each feed is formatted differently and I have to create these manually all the time so I want to try and automate the process. We would have much better control of our ecommerce if I could do this quickly with custom program.
So far I have managed, after a lot of disappointments, to connect to the sage data through the sage ODBC and populate a datagridview. I've only got this far by luck, with many errors due to me and system and software problems. I thought this would be relatively easy as I once used an app to create a word document programmatically with a very thorough guide, it's not looking so easy now. I have also added a check box column to the datagridview for selecting rows and thats as far as I have got.I was thinking perhaps of passing the selected data to an array and then creating and populating the spreadsheet.how to get selected rows from DGV.

How can I update local dataset with mysql database without making duplicates. Assuming I set some column in mysql as primary key, which has unique string.
adapter.fill will just add duplicates, but adapter.clear before that is not an option.
So I want to update if the key column is the same with mysql data and if there is option for ignore adding new row.
