If you created your database containing upper-case letters without quotation marks, the saved name of your database will be in all lowercase letters. Confirm the name of your database from the expolorer, information_schema.catalogs, or show catalogs. From other systems, such as an SDK, use the always use the 'official' name of your database. Within the application, you can still access your all-lowercase database name using upper case letters, without quotation marks, since that is transformed into a lower-case name behind the scenes. If you wish your object names to be case sensitive, always wrap definitions in double quotes. Please note that definitions in information_schema are constructed and will not match exactly what was executed on creation, including use of quotes.
