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.
