SQL Query Tree Editor for Microsoft Access An indispensable MS Access add-in for developers who use queries as the core of their applications.
Sometimes, when you try to update existing or add new records, you will receive the "Operation must use an updateable query" error. Ole Db Exception: Operation must use an updateable query.
Error details could be like this: Description: An unhandled exception occurred during the execution of the current web request. This error description is not very useful, because if you look to your SQL query it is probably correct.
Please review the stack trace for more information about the error and where it originated in the code. The reason for this error is usually one of few reasons: To update records, you need to write changes to file on disk.
I hope this tutorial was helpful and saved your time especially if you have short deadline :).
Here you will find articles and tutorials relating to Microsoft Access query designs, from planning what tables and fields will be used to selecting criteria to be applied.
There is also information on query optimization and using calculations within the query.
Hopefully you will find something of interest, whether you need to limit results of the query by applying simple criteria to designing expressions to calculate data on the fly.
If your web application can't write to disk, you can't update existing or add new records.
So, enable read/write access in database folder or move database to other folder where your application has write permission. So, to enable updating and inserting of records you need to remove Read Only attribute. Locate the file (or .accdb file if you use newer version of MS Access), right click to it and select properties. Always disconnect from database after you execute needed queries. if you open database at application level or in separated thread and garbage collector is still not destroyed a connection) you can't open another connection and change records.
So, check your code to see are you disconnected from database every time before try to execute new SQL queries.
In case that you don't want to disconnect from database because of some reason, then consider to use the same connection instead of creating new one.Tags: Adult Dating, affair dating, sex dating
