Update command in sqlite

Here in SQLite update statement, we defined few properties those are. It can be an expression or a simple value. Expression - conditions or expressions that must be met for the records to update. The SQLite UPDATE statement requires a table name followed by a list of column names or value pairs that should be assigned and the rows updation determined by a conditional expression that is tested against each row of the table.

I think I have solved the problem. I am going to try putting my database in the app's local storage folder and see if it works. I bet it does. Thanks and I will post how this works out for me.

The problem is solved. I was able to create the database, read from it, and write back to it in the App Data local stare folder where MS recommends it be stored. IBMs desire to have forward slash serve as the command line parameter switch character starting with DOS 1.

It's always been an issue from the command line, but never from the API from the time DOS began supporting hierarchical directories.

The function returns an int which means the value was It was just easier to type an E. Please be aware that if you try to make a change to a database, SQLite creates a new file in the same folder as the database.

Which means in your case that you will need write permissions for the folder your source code is in. Supplying a read-only database inside your project is often done and works fine. Giving your application write permissions to itself represents a horrible security problem and tempts malware. Chronological Unformatted History. I can't seem to decipher the extended code. It is to show you the pieces I have or don't have.

I tried all the possible ways for my file string. Without the file:, single back slashes which Windows did not like, and forward slashes. I got the same result, E. This is different from when the database was in my project folder. Yes, and with a little more information that will be a potent clue, I think. I will try it, but may have questions if this solves the problem. I don't think this is the problem. That subquery is joined against the inventory table and the quantity of each affected inventory row is reduced by the appropriate amount.

The target table is not included in the FROM clause, unless the intent is to do a self-join against the target table. In the event of a self-join, the table in the FROM clause must be aliased to a different name than the target table. If the join between the target table and the FROM clause results in multiple output rows for the same target table row, then only one of those output rows is used for updating the target table.

The output row selected is arbitrary and might change from one release of SQLite to the next, or from one run to the next. In other words, the target table is named twice in the statement. With SQL Server, the inventory adjustment statement demonstrated above would be written like this:. The equivalent MySQL statement would be like this:.
