: User-defined name(s) of the procedure’s input table(s). Detailed input table
definitions for each procedure can be found in Chapter 3.
: User-defined name of the procedure’s parameter table. The table structure is
described in Parameter Table Structure [page 11]. Detailed parameter table definition for each
procedure can be found in Chapter 3.
: User-defined name(s) of the procedure’s output table(s). Detailed output table
definition for each procedure can be found in Chapter 3.
Note
1. The input, parameter, and output tables must be created before calling the procedure.
2. Some PAL algorithms have more than one input table or more than one output table.
3. To call the PAL procedure generated in Step 1, you need the AFL__SYS_AFL_AFLPAL_EXECUTE or
AFL__SYS_AFL_AFLPAL_EXECUTE_WITH_GRANT_OPTION role.

2.5.1 Parameter Table Structure
PAL functions use parameter tables to transfer parameter values. Each PAL function has its own parameter
table. To avoid a conflict of table names when several users call PAL functions at the same time, the parameter
table must be created as a local temporary column table, so that each parameter table has its own unique
scope per session.
The table structure is as follows:
Table 3:
Column Name Data Type Description
Name Varchar Parameter name
intArgs Integer Integer parameter value
doubleArgs Double Double parameter value
stringArgs Varchar String parameter value
Each row contains only one parameter value, either integer, double or string.
The following table is an example of a parameter table with three parameters. The first parameter,
THREAD_NUMBER, is an integer parameter. Thus, in the THREAD_NUMBER row, you should fill the parameter
value in the intArgs column, and leave the doubleArgs and stringArgs columns blank.
