Hallo,
according to
http://www.postgresql.org/docs/8.4/interactive/sql-syntax-lexical.htm
A token can be a key word, an identifier, a quoted identifier, a literal
(or constant), or a special character symbol.
I suppose these different tokens are used by the internal parser?
So my questions is,
is there a function one could use to filter out the specific tokes?
Example:
Given the statement: INSERT INTO MY_TABLE VALUES (3, 'hi there');
We can do something like:
select filter_tokens($$INSERT INTO MY_TABLE VALUES (3, 'hi there');$$);
With output:
token | type
Insert keyword
into keyword
my_table identifier
values keyword
..
'hi there' literal
or in another way with similar functionality?
mvg,
Wim
