load multiple csv into one table by SQLLDR
I am using SQL LOADER to load multiple csv file in one table. The process I found is very easy like
LOAD DATA INFILE '/path/file1.csv' INFILE '/path/file2.csv' INFILE '/path/file3.csv' INFILE '/path/file4.csv' APPEND INTO TABLE TBL_DATA_FILE EVALUATE CHECK_CONSTRAINTS REENABLE DISABLED_CONSTRAINTS EXCEPTIONS EXCEPTION_TABLE FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"' TRAILING NULLCOLS ( COL0, COL1, COL2, COL3, COL4 )
But I don't want to use INFILE multiple time cause if I have more than 1000 files then I have to mention 1000 times INFILE in control file script.
So my question is: is there any other way (like any loop / any *.csv) to load multiple files without using multiple infile?
