Create function for formatting from (X-1, X-2, X-3) to ('X-1', 'X-2', 'X-3')

Question

I have a query that returns some char type keys like this X-1, X-2, X-3. The problem is that now I need to use with where chaves in( ... ) and would have to format the values to 'X-1', 'X-2', 'X-3'. That would save me some relationships...

As this is all within the query, I cannot format with PHP, so I thought about creating a function in MYSQL for this purpose, but I don’t know which functions would use.

X-1, X-2, X-3 are keys concatenated with group_concat to play in the clause in( ... ), for this reason needed to format.
