Enhancing ‘alter table’ is another kettle of fish altogether.

SQLite's PRAGMA implementations do not plug into the internal query
mechanism used by SELECT, but hardcode a VDBE program

Hi, all,
is there a syntactical construct which will allow me to use a pragma in a
subselect? e.g. i'm trying to do...
sqlite pragma table_info(vfile);
cid|name|type|notnull|dflt_value|pk
0|id|INTEGER|0||1
1|vid|INTEGER|0||0
...
sqlite select name from (pragma table_info(vfile));
Error: near (:

Other databases seem more logical on this practical matter.

Well, that pragmas are not directly queryable from SQL just add insult to
injury.
What SQLite would really benefit from is a proper, consistent, queryable data
dictionary such as the the standard
