Following are some of the tips and tricks that can be used with SQL Loader
1) Load text for a column which is having more than 4000 bytes.
Use following syntax
LOAD DATA
APPEND INTO TABLE sv_test
FIELDS TERMINATED BY '|' TRAILING NULLCOLS
(
long_text_columns char(40000)
)
2) How to use oracle functions with SQL Loader
LOAD DATA
APPEND INTO TABLE sv_test
FIELDS TERMINATED BY '|' TRAILING NULLCOLS
(
long_text_columns char(40000) --- first 40000 characters
, column1 "trim(:column1)" --- Trims and loads
, column2 "replace(:column2,'\n',chr(10))" --- replace \n with new line
, column3 DATE "DD-MON-YYYY" --- defining date style
, column4 "upper(:column4)" --- changing to upper case
, column5 "lower(:column5)" --- changing to lower case
, column6 constant "FIXED" --- assigning a constant value
, column7 "sv_sequence.nextval" --- defaulting a value from sequence
)
