Oracle's SQL*Loader utility is used to load data from flat files into Oracle tables. You'll have to figure out...
how the data in the flat files maps to your table in the database. For instance, assume we have a CSV file call in_data.txt that looks like the following:
7782, "Clark", "Manager", 7839, 09-June-1981 7839, "King", "President", , 17-November-1981 7934, "Miller", "Clerk", 7782, 23-January-1982 7566, "Jones", "Manager", 7839, 02-April-1981This data will be loaded into the SCOTT.EMP table. You can create a SQL*Loader control file called in_data.ctl that looks like the following:
LOAD DATA INFILE in_data.txt APPEND INTO TABLE scott.emp FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"' (empno, ename, job, mgr, hiredate DATE(20) "DD-Month-YYYY")Once you have the control file and the input file, you can load it all as follows:
sqlldr userid=scott/tiger control=in_data.ctl log=in_data.logThere are many more options for SQL*Loader in the Oracle documentation. Please read the Utilities guide.
