Unfortunately MySql didn't implement table-valued parameters, but alternatives do exist:

• Using a temporary table which drops immediately after the connection closes but is visible to all queries coming via this connection. The only con is having to execute an additional query (or more) before the intended query, just to insert data into the temp table.
• Using a delimited string ("str1,str2,str3") which significantly downgrades performance, especially when the string is very long.
