DECLARE NAMETYPE Declaration

The DECLARE NAMETYPE declaration is a compiler directive that sets the default

NAMETYPE attribute value to ANSI or NSK for static SQL statements that follow the

declaration within a compilation unit.

DECLARE NAMETYPE is used by the preprocessor when the INVOKE directive is not

fully qualified.

DECLARE NAMETYPE is an SQL/MX extension that you use only in embedded SQL

programs.

default-nametype

is a character string literal that specifies the NAMETYPE attribute value used to

refer to SQL/MP database objects. 'ANSI' indicates logical names (ANSI), and

'NSK' indicates physical Guardian names.

If you do not specify DECLARE NAMETYPE, the default NAMETYPE is ANSI.

Considerations for DECLARE NAMETYPE

Scope of DECLARE NAMETYPE

You can specify more than one DECLARE NAMETYPE directive in an embedded SQL

program. Each directive replaces the preceding directive and stays in effect until it is

replaced by another directive or until the end of the program’s compilation unit is

reached.

If no DECLARE NAMETYPE directive is in effect when the SQL/MX compiler

encounters an unqualified object name, the compiler uses the value of the NAMETYPE

attribute as determined by NonStop SQL/MX. For more information, see Object

Naming on page 10-48 and the SQL/MX Programming Manual for C and COBOL.

C Examples of DECLARE NAMETYPE

•

Set the default NAMETYPE attribute value to use Guardian physical names:

EXEC SQL DECLARE NAMETYPE 'NSK';

COBOL Examples of DECLARE NAMETYPE

•

Set the default NAMETYPE attribute value to use Guardian physical names:

EXEC SQL DECLARE NAMETYPE 'NSK' END-EXEC.
