Re: SQL Loader

I tried loading 700k records with a Delphi4 program. I estimated that it would take approx. 10 hrs to load into Oracle table. With SQL*Loader loading the same records it took about 1.5 Minutes! Below is the control file I used. The truncate command(good for bulk deletes) is what I think you want to use before you load data so your table is clean.

Sample control file:

• Requires CR/LF on last line of control file.

OPTIONS (DIRECT=TRUE, PARALLEL=FALSE)
UNRECOVERABLE
LOAD DATA
INFILE 'aithw.dat'
TRUNCATE
INTO TABLE AIT.AITHW ("STATE" POSITION (01:02) CHAR,

"AREA" POSITION (03:09) CHAR,
"IMPORT_DAT" POSITION (10:15) CHAR,
"CPR" POSITION (16:21) CHAR,
"FRC" POSITION (25:29) CHAR,
"FLOOR" POSITION (30:31) CHAR,
"FRAME_ID" POSITION (32:40) CHAR,
"YR" POSITION (41:42) CHAR,
"QTY" POSITION (43:50) CHAR,
"MAT_COST" POSITION (51:62) CHAR,
"INPL_COST" POSITION (63:74) CHAR,
"ECN" POSITION (75:79) CHAR,
"ECN_INPL" POSITION (80:91) CHAR,
"BASIC" POSITION (94:105) CHAR,
"PART" POSITION (106:132) CHAR)

Sql*Loader WinNT Dos command(for sample data file):

sqlldr80 userid=username/password_at_alias control=controlfile.ctl discard=discardfile.dsc data=datafile.dat
