I have null values to be inserted into a table whose column is created as NOT NULL.

How do i go about it?

Here is the sqlldr log:

Record 1: Rejected - Error on table XYZ.
ORA-01400: cannot insert NULL into ("XYZ"."MER_CDE")

Record 2: Rejected - Error on table XYZ.
ORA-01400: cannot insert NULL into ("XYZ"."MER_CDE")

Record 3: Rejected - Error on table XYZ.
ORA-01400: cannot insert NULL into ("XYZ"."MER_CDE")

MER_CDE is 6th column from right.

while creating the table, the following columns shown under have been created as NOT NULL.

While in the data in these columns may have a null value.

For Example MER_CODE column has null values in the sample data shown below

MER_CDE VARCHAR2(30) NOT NULL, --null values in data
PRD_LNE VARCHAR2(40) NOT NULL, --may have null values in data
CLS_CDE VARCHAR2(40) NOT NULL, --may have null values in data
CTG_IND VARCHAR2(40) NOT NULL,
FOR_CDE VARCHAR2(40) NOT NULL,
SHP_CDE VARCHAR2(40) NOT NULL,

Q Should i disable all constraints in the table, and load all data through sqlldr and then enable the constraints?
