A further detail to the max_string_size setting - you have to be in upgrade mode and run an upgrade script to enable it, and you can't downgrade the database afterwards.

See the 12.2 reference manual on the parameter for details:  https://docs.oracle.com/database/121/REFRN/GUID-D424D23B-0933-425F-BC69-9C0E6724693C.htm#REFRN10321

Thanks Norman, Db is 12.2 but maxsize is not extended. I will test on Sandbox and test it.

What version of Oracle? In the limits section of the manual for 11g, the VARCHAR2 data type is limited to 4,000 bytes. Check the "Reference" manual for your version.

For version 12 it's also 4,000 but can be 32,767 if you have set MAX_STRING_SIZE to EXTENDED in the spfile.

Cheers,
Norm.
