Updating multiple table
Now that you have created the Products table, you are ready to insert data into the table by using the INSERT statement.
After the data is inserted, you will change the content of a row by using an UPDATE statement.
For small numbers of rows requiring updates, it can be adequate to use an UPDATE statement for each row that requires an update.
But if there are a large number of rows that require an update, then the overhead of issuing large numbers of UPDATE statements can result in the operation as a whole taking a long time to complete.
You will use the WHERE clause of the UPDATE statement to restrict the update to a single row. The basic syntax is: INSERT, table name, column list, VALUES, and then a list of the values to be inserted.
The two hyphens in front of a line indicate that the line is a comment and the text will be ignored by the compiler.
Last week, we have learned what Pivot Table Report Filters are & how to use them.
Today, I am going to show, how you can use simple macro code to change the report filter value dynamically. JSON API is designed to minimize both the number of requests and the amount of data transmitted between clients and servers.This efficiency is achieved without compromising readability, flexibility, or discoverability. I believe in your case, you want it the other way around. LAST_NAME; The script above will update information in PERSONS_TMP table using data from PERSONS table.A more effective solution to this problem is to attempt to reduce the number of UPDATE statements.
