Working with NULLs [CR #626626]

In Moving Data In and Out of Databases > Converting data on insertion > Working with NULLS, the syntax and example should be “NULL” instead of “NULLS”.

The correct syntax is:

NULL ({BLANKS | ZEROS | literal' ['literal']...})

The correct example is:

LOAD TABLE lineitem(
    l_orderkey NULL(ZEROS) ASCII(4),
    l_partkey ASCII(3),
    l_shipdate date('MM/DD/YY'),
    l_suppkey ascii(5),
FILLER(1))
FROM 'C:\\MILL1\\tt.t'
PREVIEW ON

All other instances of the word “NULLS” in this section should be “NULLs”.
