Updating a field in sql
If you try to run an action query and it seems like nothing occurs, check the Access status bar for the following message: This action or event has been blocked by Disabled Mode.
By default, Access disables all action queries (update, append, delete, or make table queries) unless your database is in a trusted location or the database is signed and trusted.
In some cases, the conversion process might delete some data.
For more information about restrictions when you convert data types, see the section Restrictions on data type conversions.
The process of updating data from one table to another follows these broad steps: The steps in this section assume the use of two similar tables.
In this example, the Clients table is located in a database that you just inherited, and it contains more recent data than the Customers table.
but finally realize that it has wrong data without any Extension at the end of the data, in One of the column of the table, so now I want to change the column data of multiple rows based on specific ID? I just want to add '.jpg' at the end on these data.
Furthermore, when you update data from one table to another and use compatible data types instead of matching data types, Access converts the data types of those fields in the destination table.
As a result, some of the data in the destination fields may be truncated (deleted).
You can see that some of the manager names and addresses have changed.
For that reason, you decide to update the Customers table with the data from the Clients table.
