The following code demonstrates how to load CLOB data (greater than 32 KBytes) from a file into a CLOB column.
The package DBMS_LOB is used to access a file stored on the operating system and load that data into a CLOB column.
The DBMS_LOB.LOADCLOBFROMFILE() procedure loads the contents of the BFILE into the CLOB column using DBMS_LOB.LOBMAXSIZE which loads until the end of the BFILE is reached.
This method allows the data to be loaded up to the maximum size that the CLOB column can hold. Passing DBMS_LOB.LOBMAXSIZE causes the procedure to read the entire BFILE. This is a useful technique for reading the entire LOB without introspecting the size of the LOB.
