Hi, I just tried to input a hexadecimal number in PostgreSQL (8.4) and was rather surprised by the result:
| tim=# SELECT 0x13; | x13 | ----- | 0 | (1 Zeile) | tim=# SELECT 0abc; | abc | ----- | 0 | (1 Zeile) | tim=# The documentation says: | A token can be a key word, an identifier, a quoted identifi- | er, a literal (or constant), or a special character symbol. | Tokens are normally separated by whitespace (space, tab, | newline), but need not be if there is no ambiguity (which is | generally only the case if a special character is adjacent | to some other token type). Is this behaviour really conforming to the standard? Even stranger is what MySQL (5.1.59) makes out of it: | mysql> SELECT 0x40; | +------+ | | 0x40 | | +------+ | | @ | | +------+ | 1 row in set (0.00 sec) | mysql> SELECT 0abc; | ERROR 1054 (42S22): Unknown column '0abc' in 'field list' | mysql> Tim -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
