OpenEdge Data Management: DataServer for Microsoft SQL Server

Interfacing with RDBMS stored procedures
Example 10 shows ABL procedure results of the previous stored procedure pcust as
it is written into the new buffers pcust_orders and pcust_states.
/* Results of the first two example code examples - Typed buffers */
RUN STORED-PROC pcust (20, output 0, output 0).
FOR EACH pcust_orders:
DISPLAY pcust_orders.
END.
FOR EACH pcust_states:
DISPLAY pcust_states.
END.
CLOSE STORED-PROC pcust.
DISPLAY pcust.orders pcust.states.
Example 10: Result set of pcust - typed buffers
Because two different buffers have been defined, the returned values maintain their
data types instead of being converted to character strings and stored in the
OpenEdge-defined buffer proc–text–buffer. You can then use the returned values
in calculations without first converting them back to their original data types. In addition,
the two separate buffers make your output look cleaner, allowing ABL to build a new
default frame for the two different types of output. Reading your results into an explicitly
defined buffer also allows you to manipulate the data just as you would manipulate data
from an OpenEdge database; for example, with Frame phrases and FORM statements.
