Advanced Oracle PL/SQL Programming with Packages

5.4. PLVcase: PL/SQL Code Conversion

The PLVcase (PL/Vision CASE) package converts the case of PL/SQL source code so that it conforms to the UPPER-lower method (reserved words in upper-case, application-specific identifiers in lower-case). See Chapter 18 for details.

5.4.1. Package constants

c_usecor CONSTANT VARCHAR2(3) := 'COR';

The constant used in calls to module (see below) to indicate that a CREATE OR REPLACE should be appended to the source code for the program unit.

c_nousecor CONSTANT VARCHAR2(4) := 'NCOR';

The constant used to tell module to not append the CREATE OR REPLACE to the program unit.

5.4.2. Case-converting programs

FUNCTION token (token_in IN VARCHAR2, pkg_in IN VARCHAR2 := NULL)
RETURN VARCHAR2;

Converts the case of a single token according to the UPPER-lower method.

PROCEDURE line
   (line_in IN OUT PLVio.line_type,
    line_out IN OUT PLVio.line_type,
    found_out OUT BOOLEAN);

Converts the case of a single line of source code according to the UPPER-lower method (it calls PLVcase.token for each token in the string).

FUNCTION string (string_in IN VARCHAR2) RETURN VARCHAR2;

Converts the case of a string according to the UPPER-lower method. It formats the string as necessary for a call to the PLVcase.line procedure.

PROCEDURE string (string_inout IN OUT VARCHAR2);

Procedure version of the string function. It hands you back your own string variable with the case of the tokens converted.

PROCEDURE module (module_in IN VARCHAR2, cor_in IN VARCHAR2 := c_usecor, ...
