MySql create temporary table from source table without indexes
I'm trying to "duplicate" a table from my db creating a temporary one. However I need indexes are not copied.
I'm using this query right now:
CREATE TEMPORARY TABLE temp365 LIKE contactlens;
but the result table contains also indexes. I checked out the documentation and I don't see a way to copy the structure without indexes.
Because I can't have static name for indexes, I was wondering how I can drop all of them using simple SQL.
I was starting trying to avoid to copy them at all, but it seems not possible.
