Bug reference: 3894
Description: JDBC DatabaseMetaData.getTables is inconsistently
case-sensitive with schema name
Details:
create schema DEV;
but then DatabaseMetaData.getTables(null, "DEV", "%", new String[]
{"TABLE"}) returned an empty resultset.
However giving it the schema name "dev" returns the full resultset.
This is by design. While SQL provides case folding and quoting rules
those are not the same as the JDBC driver's rules. In SQL an unquoted
identifier is case folded while quoted identifiers are not. To provide
the most straightforward mapping for the JDBC driver, we require an exact
match because quoting in Java String objects isn't the same as SQL. It
would be odd to say getTable(..., "\"Dev\"",...) to imply that you wanted
a case sensitive match. Even odder would it be to do a search for a
schema with a quote in it's name using SQL identifier rules in Java code.
