Sql updating a table with values from another table
If you have not taken either of these actions, you can still enable the query for the current database session by clicking Enable Content on the Message Bar.
Top of Page If you're comfortable working with SQL, you can also write an UPDATE statement by using SQL view.
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.
If the original value is in the form of a valid Internet Protocol (IP) address (four number triplets separated by a period: nnn.nnn) and the numbers happen to coincide with a Web address, the conversion results in a valid link.
For example, you can convert a Currency field to an Integer field only when those values are greater than 255 and do not exceed 32,767. Access tries to convert other values, meaning that you see underlined text, and the cursor changes when you point at the link, but the links don't work.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).the UPDATE statement is especially useful when you want to change many records or when the records that you want to change are in multiple tables. This is one of the most interesting questions I keep on getting on this email and I find that not everyone knows about it. Our requirement is that we have Table2 which has two rows where Col1 is 21 and 31.
