回答1:
The error message is because the data read in from the data file is larger that sqlldr's default character buffer of 255 which is used if no CHAR and size is specified. Note this is different then the size of the column that the field corresponds to. For example, if I have a table column of VARCHAR2(4000), but do not explicitly give a size in the control file
cola not null,
and the data in the data file exceeds 255 but is less than 4000 in length, you'll get the error.
However, if the control file states the buffer size like this:
cola char(4000) not null,
all will be good as if creates a larger buffer (here it matches the column size). So, just get in the habit of always including the column sizes. Save yourself some hassle and create a function to generate a default control file for you...wait I posted mine for you, give it a try: https://stackoverflow.com/a/37947714/2543416
回答2:
Use CHAR(NN) in your control file for a column which exceeds its length 255.
So your control file should like this;
LOAD DATA
INFILE '$IN_DIR/$FILENAME'
BADFILE '$REJ_DIR/$FILENAME.bad'
APPEND
INTO TABLE test
FIELDS TERMINATED BY ","
TRAILING NULLCOLS
(
FILE_RECORD_DESCRIPTOR POSITION(1),
LINE_NO FILLER,
DEPT TERMINATED BY "\n",
SEQ_NO CONSTANT "1",
DEPT_NO CHAR(4000),
STATUS CONSTANT "U",
PROCESS_ID CONSTANT "2"
)
I do not know how to use CHAR(4000) with CONSTANT "0". Bu this should solve the problem.
