My table has one clob column and one blob column. I need to insert data into it through insert statements.

The length of data to be inserted is more than 4000 chars.

When I do export of insert statements is sql navigator I get empty values.

```
INSERT INTO mytable VALUES('REQUEST',EMPTY_CLOB(),EMPTY_BLOB());

```

I also tried to do insert it data like this.I have added only example data to be inserted.The actual data to be inserted is large. 

```
INSERT INTO mytable VALUES('REQUEST2','{"customer"asxcbasjbab....:}',NULL);

```

Can some one tell me best way to insert data into table in these scenario.

Or anyway to do export and import this data will also help.
