如何使用SQL插入BLOBcreate or replace directory utllobdir

create table bfile_tab (bfile_column BFILE); create table t (blob_column BLOB);

declare a_blob BLOB; a_bfile BFILE := BFILENAME('UTLLOBDIR','test.jpg'); begin insert into bfile_tab values (a_bfile) returning bfile_column into a_bfile; insert into t values (empty_blob()) returning blob_column into a_blob; dbms_lob.fileopen(a_bfile); dbms_lob.loadfromfile(a_blob, a_bfile, dbms_lob.getlength(a_bfile)); dbms_lob.fileclose(a_bfile); commit; end; 要较新的版本才支持
