BLOCK FACTOR 1000
PREVIEW ON
In this UNIX example, the FILLER(1) clause prevents Adaptive Server IQ
from inserting a NULL in the next column (VWAP) after the DATETIME
column:
LOAD TABLE snapquote_stats_base
SYMBOL ‘\x09’,
snaptime DATETIME('MM/DD/YY hh:mm:ss'),
FILLER(1))
VWAP ‘\x09’,
RS_DAY ‘\x09’,
FROM '/d1/MILL1/tt.t'
BLOCK FACTOR 1000
PREVIEW ON
In this UNIX example, the destination columns contain TIME data, but the input
data is DATETIME . You use the TIME conversion option, and use FILLER to skip
over the date portion.
LOAD TABLE customer(
open_time TIME('hh:mmaa'),
close_time TIME('hh:mmaa'),
FILLER(9))
FROM '/d1/MILL1/tt.t'
BLOCK FACTOR 1000

Specifying the format for DATETIME conversions
Specify the format of the
DATETIME
input data using:
• Y or y for years
• M or m for months
• D or d for days
• H or h to indicate hours

separators
