PLSQL_CODE_TYPE specifies the compilation mode for PL/SQL library units.

Property Description

Parameter type

String

Syntax

PLSQL_CODE_TYPE = { INTERPRETED | NATIVE }

Default value

INTERPRETED

Modifiable

ALTER SESSION, ALTER SYSTEM

Modifiable in a PDB

Yes

Basic

No

Values

  • INTERPRETED

    PL/SQL library units will be compiled to PL/SQL bytecode format. Such modules are executed by the PL/SQL interpreter engine.

  • NATIVE

    PL/SQL library units (with the possible exception of top-level anonymous PL/SQL blocks) will be compiled to native (machine) code. Such modules will be executed natively without incurring any interpreter overhead.

When the value of this parameter is changed, it has no effect on PL/SQL library units that have already been compiled. The value of this parameter is stored persistently with each library unit.

If a PL/SQL library unit is compiled native, all subsequent automatic recompilations of that library unit will use native compilation.
