When using INSERT…SELECT between a target and a source table, it is mandatory to ensure that the datatypes returned by the SELECT statement are compatible with the datatypes in the target table. It's less efficient than using inner join because join can take advantage of the index on the join column if it exists. You must be thinking what about SQL Injection? Creating queries like this dynamically is very prone to SQL injection. If this becomes a problem, you can use application control to disable the off-brand browser.
