The result will tell you whether the PAL functions were successfully installed on your system.
2.5 Calling PAL Functions
To use PAL functions, you must do the following:
●
●
From within SQLScript code, generate a procedure that wraps the PAL function.
Call the procedure, for example, from an SQLScript procedure.
Step 1 – Generate a PAL Procedure
Any user granted with the AFLPM_CREATOR_ERASER_EXECUTE role can generate an AFLLANG procedure for a
specific PAL function. The syntax is shown below:
CALL SYS.AFLLANG_WRAPPER_PROCEDURE_CREATE (‘’, ‘’,
‘’, '', );

●
: Always set to AFLPAL.
: A PAL built-in function name.
: A name of the schema that you want to create.
: A name for the PAL procedure. This can be anything you want.
: A user-defined table variable. The table contains records to describe the position,
schema name, table type name, and parameter type, as defined below:
(
POSITION int,
SCHEMA_NAME nvarchar(256),
TYPE_NAME nvarchar(256),
PARAMETER_TYPE varchar(7)
)
A typical table variable references a table with the following definition:
Table 1:
Position Schema Name Table Type Name Parameter Type
1 IN
2
IN
3 OUT
Note
1. The SYS.AFLLANG_WRAPPER_PROCEDURE_CREATE is in invoker mode, which means, the invoker must
be allowed to read the table.
