Hi all,
while writing test cases for my SQL pretty printer tool[1], I found what seems
a discrepancy in the "Type Casts" documentation[2]: it states that the two
syntaxes are equivalent, but while
CREATE TABLE contracts (
...
company_id uuid NOT NULL,
validity daterange NOT NULL,
EXCLUDE USING gist (CAST(company_id AS text) WITH =, validity WITH &&)
)
works, the following
CREATE TABLE contracts (
...
company_id uuid NOT NULL,
validity daterange NOT NULL,
EXCLUDE USING gist (company_id::text WITH =, validity WITH &&)
)
is rejected with the message "syntax error at or near "::"".
Am I misreading the documentation, or is it missing some special case?
Thanks in advance for any explanation,
ciao, lele.
