Today, software providers are dedicated to providing users with options for a better visual experience within their programs and applications. With the launch of dark mode in Quest® Toad® for Oracle 15.1, I am so excited to choose a visual theme that pays homage to my early days of programming! Benefits of dark mode My user experience was almost always a black screen with yellow letters. The monitors in those days used to be composed of cathode ray tubes, and I hardly worked with graphic interfaces at that time. It was a wonderful gift because it allowed me to stop programming on paper and start programming for real! At that time, I programmed in Turbo Pascal and spent long hours in front of the monitor, marveling at everything we could do as programming apprentices. When I was in my second year at university, I was delighted to receive a personal computer XT as a gift. This can be accomplished with a simple SELECT query on the USER_TABLES data dictionary.Remember the old days of original “dark mode?” I do. Viewing Tables Owned by Current userĪt the most basic level, you may wish to view a list of all the tables owned by the current Oracle user. The values in these stored dictionaries are updated automatically by Oracle anytime a statement is executed on the server that modifies data.įrom there, the read-only dictionaries can be read and queried just like any standard table, which as we’ll see below provides some very useful functionality. What are Oracle Data Dictionaries?Ī data dictionary in Oracle is a collection of read-only tables that provide useful information about the database including schemas, users, privileges, and even auditing data. Thankfully, there are multiple ways to perform this relatively simple task in Oracle, so we’ll briefly explore each option below to find which best suits your needs. As with most relational databases, there may come a situation where you need to view the the underlying metadata and look through the actual table list and ownership of your database.
