To adjust a table name within a SQL statement, you need to create a
string with the updated values and use PREPARE/EXECUTE
See below, I am replacing your CONCAT with the complete insert statement
The example below is also assuming the value in the WHERE clause should
be adjusted to the number, instead of hard-coded to '9'
set @str = concat('Insert Into test (Panel_Id) select Panel_Id
from ',Project_Number_val,'_List where Project_Number_val='
,"'",Project_Number_val,"'");
prepare stmt from @str;
execute stmt;
deallocate prepare stmt;
