Notes:
LT
parameter applies to all statements
retrieving records from the database; that is, statements that initiate processing loops,
such as READ
, FIND
, HISTOGRAM
or SELECT
, and statements that retrieve only a single record,
such as FIND
UNIQUE
, FIND NUMBER
, FIND FIRST
,
GET
(SAME
) and SELECT
SINGLE

LT
limit. The count also includes those records which were
rejected by a WHERE
clause of a FIND
, READ
or
HISTOGRAM
statement. The LT
limit does not affect
the statements STORE
, UPDATE
, DELETE
, END

and BACKOUT TRANSACTION

LT
parameter. If the incremented count exceeds the current LT
value,
Natural error NAT1003 (Global limit for database calls reached
) is
raised. The count of retrieved records is reset to zero whenever a Natural program is
started on Level 1. The count is not reset if the program on Level 1 invokes another
Natural object (for further information, see Multiple
Levels of Invoked Objects in the Programming
Guide). Therefore, the LT
parameter limits the number
of records retrieved from the database by a Level 1 program and objects invoked by that
program on a level other than 1.
LT
parameter is dynamically changed within
a program by using a SET GLOBALS LT=n
statement,
the new limit value becomes effective for the next statement that retrieves a record from
the database.
LT
can be
overridden by using the session parameter LT
.
