Input Data :-(Datafile) cat /home/oracle/employee.txt Log File contains a detailed summary of the load, including a description of any errors that occurred during the load.Ĭreate the table structure:- SQL> create table employee(emp_id integer,emp_name varchar2(10),dept varchar2(15),salary integer,Join_date date) Bad File contains the records which are rejected either by SQL Loader or by the database because of the bad formatting or data type mismatch.It will have the same name as the data file, with a. Discard file contains rejected rows those were discarded because they were filtered due to a statement in SQL*Loader control file. Data written to any database table is not written to the discard file.Ĥ. ( emp_id, emp_name, dept, salary ) – Lists the name of the column names in the table into which the data should be uploadedģ.fields terminated by – Indicates the delimiter that is used in the input file to separate the fields.into table – Indicates the table name where this data should be inserted.infile – Indicates the location of the input data file.The above control file indicates the following: This tells sqlldr the location of the input file, the format of the input file, and other optional meta data information required by the sqlldr to upload the data into oracle tables. Control file contains the instructions to the sqlldr utility.Input Datafile contains file containing the data to be loaded.The record format can be specified in the control file with the INFILE parameter.Use conventional, direct path, or external table loads.Use secondary data files for loading LOBs and collections.Load arbitrarily complex object-relational data.Generate sophisticated error reports, which greatly aid troubleshooting.Load data from disk, tape, or named pipe.Use the operating system’s file system to access the data files.Generate unique sequential key values in specified columns.Manipulate the data before loading it, using SQL functions.Selectively load data (you can load records based on the records’ values).Load data into multiple tables during the same load session.Load data from multiple data files during the same load session. Load data across a network if your data files are on a different system than the database.You can use SQL*Loader to do the following: It has a powerful data parsing engine that puts little limitation on the format of the data in the data file. SQL*Loaderloads data from external files into tables of an Oracle database.
