MySql SELECT AS - Append all field names

Tags:

mysql

I'd like to do something like this:

SELECT table.id AS prefix_id, table.name AS prefix_name

... and have the prefix added dynamically to all field names rather than selecting them all manually (ie SELECT table.* AS prefix_* or something)

Hopefully I've described that accurately. Any thoughts?

Edit

To be clear, the reason I'm asking is to make sure that my query result contains every column from each table I call even if there are duplicate field names. For example, I might have a table with lots of fields which means I don't want to alias all the fields manually. Further if 3 tables have a field called name my result won't contain three name results; it will have one. I want to avoid ambiguity with my column names.

To avoid ambiguity in columns with multiple tables it appears you must manually specify each column name that exists with the same name in more than one table.
