SELECT is the most common operation in SQL, called "the query". SELECT retrieves data from one or more tables, or expressions. Standard SELECT statements have no persistent effects on the database.

Ada Pro*Ada was officially desupported by Oracle in version 7.3. Starting with Oracle8, Pro*Ada was replaced by SQL*Module but appears to have not been updated since. [7] SQL*Module is a module language that offers a different programming method from embedded SQL.
Number = 6 Then 'Select Case statement is typically better solution Resume FinallyLabel 'continue execution on specific label. Typically something with meaning of "Finally" in other languages 'or Resume Next 'continue execution on statement next to "Err.Raise 6" 'or Resume 'continue execution on (repeat) statement "Err.Raise 6" End If MsgBox Err .
SQL Plus internal commands, for example: environment control commands such as SET; environment monitoring commands such as SHOW; Comments; External commands prefixed by the ! char; Scripts can include all of these components. An Oracle programmer in the appropriately configured software environment can launch SQL Plus, for example, by entering:
Python. The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [19] The enclosed text becomes a string literal, which Python usually ignores (except when it is the first statement in the body of a module, class or function; see docstring). Elixir
The GRANT statement enables system administrators to grant privileges and roles, which can be granted to user accounts and roles. These syntax restrictions apply: GRANT cannot mix granting both privileges and roles in the same statement. A given GRANT statement must grant either privileges or roles. The ON clause distinguishes whether the ...
