Test-Import LOB type data using SQL Lorader

1. Prepare the data files that need to be transferred and transfer them to the server

2. Create a new target table in the database

DROP TABLE lob_tab;CREATE TABLE lob_tab (  number_content    NUMBER(10),  varchar2_content  VARCHAR2(100),  date_content      DATE,  clob_content      CLOB,  blob_content      BLOB);

3. Write the control file for SQL loader (named: LOB_TEST.CTL)

LOADDATA INFILE' Lob_test_data.txt '    into TABLELob_tab Fields TERMINATED by ', '(number_contentCHAR(Ten), Varchar2_contentCHAR( -), Date_contentDATE "Dd-mon-yyyy" ":d ate_content", Clob_filename FILLERCHAR( -), Clob_content lobfile (clob_filename) TERMINATED byEOF, Blob_filename FILLERCHAR( -), Blob_content lobfile (blob_filename) TERMINATED byEOF)

It is important to note that the FileName field is defined as the filler type, which serves as the lobfile information during the transfer and does not pass into the database.
4. Use the following command to import data into the database

sqlldr userid=test/test@db10gcontrollog=lob_test.log bad=lob_test.bad

After you use the Tera term to execute the command, the import succeeds.
