Hello,
I have a Virtual database connection to Teiid using PostgreSQL ODBC
driver 8.04.02.00. When running my SQL queries everything complets
successfully, but the Column Names are all coming back lower case. I did
quite a bit of research on this and am finding that if the alias is in
Double Quotes it should be case-insensitive, but this is not what is
happening. Is there a setting in the configuration for this? I have gone
through all the setting and did not see anything specific to
case-insensitive.
If I am following you, then you have this backwards.
See:
http://www.postgresql.org/docs/9.3/static/sql-syntax-lexical.html
Quoting an identifier also makes it case-sensitive, whereas unquoted
names are always folded to lower case. For example, the identifiers FOO,
foo, and "foo" are considered the same by PostgreSQL, but "Foo" and
"FOO" are different from these three and each other. (The folding of
unquoted names to lower case in PostgreSQL is incompatible with the SQL
standard, which says that unquoted names should be folded to upper case.
Thus, foo should be equivalent to "FOO" not "foo" according to the
standard. If you want to write portable applications you are advised to
always quote a particular name or never quote it.)
Thank you,
