I'm trying to write a query that uses the function "json_array".
e. g.:
select json_array(column1,column2) from tb1.
And thats work right.
But how can i use this functions without writing a columns name.
e. g.:
select json_array(*) from tb1.

Directly not possible. You will need to use Information_schema to get the name of columns in a specific table; then prepare a dynamic sql query and execute it.
