5.26. PLVtkn: Token Table Interface
The PLVtkn (PL/Vision ToKeN) package provides an interface to the PLV_token table; the package examines this table to determine whether an identifier is a keyword. See Chapter 10 for details.
5.26.1. Package constants
c_any CONSTANT CHAR(1) := '%'; c_syntax CONSTANT CHAR(1) := 'X'; c_builtin CONSTANT CHAR(1) := 'B'; c_symbol CONSTANT CHAR(1) := 'S'; c_exception CONSTANT CHAR(1) := 'E'; c_datatype CONSTANT CHAR(1) := 'D'; c_datadict CONSTANT CHAR(2) := 'DD'; c_sql CONSTANT CHAR(3) := 'SQL';
Each of these constants specify a different type of token or reserved word in the PL/SQL language (except for c_any, of course). They match the values found in the PLV_token_type table. They are used by various programs in the PLVtkn package.
c_plsql CONSTANT CHAR(1) := '%'; /* = c_builtin */ c_od2k CONSTANT CHAR(4) := 'OD2K'; c_of CONSTANT CHAR(2) := 'OF'; c_or CONSTANT CHAR(2) := 'OR'; c_og CONSTANT CHAR(2) := 'OG';
These constants identify different categories or sets of reserved words for the PL/SQL language. The identifier SHOW_ALERT is, for example, a builtin in Oracle Forms, but has no significance in the stored PL/SQL code. Currently PL/Vision is aware of stored PL/SQL and Oracle Forms reserved words only.
5.26.2. The keyword record TYPE
TYPE kw_rectype IS RECORD (token PLV_token%token, token_type PLV_token%token_type, is_keyword BOOLEAN);
A PL/SQL record TYPE defining a record holding information about a token.
