How to export clob field datas in oracle sql developer

Question

How to export clob field data's in oracle sql developer. Currently clob field data's can't export in oracle sql developer.

Answer 1

If you don't want to (or can't) export and import your data, and really want it as a set of insert statements, you can use SQL Developer's built-in formatting tools to automatically split your CLOBs into multiple chunks that are small enough to be valid as string literals, and then spool the result to a file:

spool clob_export.sql
select /*insert*/ * from your_table;
spool off

With more recent versions you can use the sqlformat command to control the output format without needing to modify the query; this is equivalent:

set sqlformat insert
spool clob_export.sql
select * from your_table;
spool off

The generated insert statements will look something like:

REM INSERTING into YOUR_TABLE
SET DEFINE OFF;
Insert into YOUR_TABLE (ID,CLOB_COLUMN) values (1,TO_CLOB('... up to 4k of characters with quotes escaped ...')
|| TO_CLOB('... up to 4k of characters with quotes escaped ...')
|| TO_CLOB('... up to 4k of characters with quotes escaped ...')
...
|| TO_CLOB('... up to 4k of characters with quotes escaped ...'));
