Hello,

sqlite> create table source_table(value);
sqlite> create table max_value(max_value);
sqlite> insert into max_value select max(value) from source_table;
sqlite> select * from table_max_value;
max_value

sqlite>


How can the maximum value of column source_table.value be inserted into
max_value only if there are records in source_table? (If source_table is
empty, nothing should be inserted into max_value, not even a NULL)
