JDBC/thin conversion of "\U3000" to ASCII 0x00 (null) with database with a US7ASCII character set (Doc ID 1360923.1)

Last updated on JUNE 01, 2017

Applies to:

JDBC - Version 11.2.0.2.0 and later
Information in this document applies to any platform.

Symptoms


JDBC/thin testcase application shows that a UNICODE CHARACTER "\U3000" is converted to 00 (null) when inserted in to a database with a US7ASCII character set.
On one hand it is expected since the JDBC driver is preventing non-ascii characters from being stored in the database, however storing a character of 00 (null) in character columns will cause problems with applications retrieving content as strings.

This issue does not occur with databases using other character sets, multi-byte charactersets.

This is only an issue with the thin driver. The OCI driver behaves as expected and inserts question mark (3F) which is the standard replacement character for ASCII.
