Problem:
I want to do this operation
select name from pragma table_info(my_awesome_table)
However, it yields a syntax error. I have the sneaking suspicion this is possible, but it doesn't seem to be documented as usable in t开发者_如何学Che SELECT docs with sqlite.
Since SQLite 3.16.0 we can use PRAGMA functions
sqlite> create table my_table (a int, b TEXT);
sqlite> .headers ON
sqlite> .mode columns
sqlite> pragma table_info(my_table);
cid name type notnull dflt_value pk
---------- ---------- ---------- ---------- ---------- ----------
0 a int 0 0
1 b TEXT 0 0
sqlite> select name from pragma_table_info('my_table');
name
----------
a
b
