The LONG datatype stores variable-length character strings containing up to two gigabytes, but with many restrictions. However when after sequence "1" we receive file with sequence "500" we are not able to store the gap string in the table with data type varchar2(4000). When calling PL/SQL procedures with data that exceeds 32,767 bytes in length, cx_Oracle automatically creates a temporary LOB internally and passes that value through to the procedure. Css Use clob type in PL/SQL: 3. Oracle has many types of large objects (BLOB, CLOB, LONG, LONG RAW), and you need to run a utility to find the actual used space in a long object (CLOB) data type length within a table. Viewed 15k times 1. Note: INSERT DML, Only the file pointer is stored into the table by BFILENAME function but file is stored in filesystem. If the data is on a physical file system in a file - then you need to load that file's contents into a LOB and insert that LOB.
