ALLOWNULLCHAR

Allows programs to use PIC X(n) host variables, and to select/insert/update hexadecimal characters in CHAR columns without changing source to use SQL TYPE BINARY host variables.

Syntax:

ALLOWNULLCHAR
NOALLOWNULLCHAR

Properties:

Default:

NOALLOWNULLCHAR

Scope:

Used at compile time:	No
Behavior at run time:	Process

See Scope - OpenESQL SQL Compiler Directive Options for more information.

Comments:

ALLOWNULLCHAR applies to native runtime only.

PostgreSQL does not support the embedding of the NULL character into CHAR columns; therefore ALLOWNULLCHAR is not supported in PostgreSQL OpenESQL applications.
