[DataDirect][ODBC Progress OpenEdge Wire Protocol driver][OpenEdge]Internal error 2 (A buffer other than the NLS system handle memory was not large enough) in SQL from subsystem NLS SERVICES function nls_conversion_t::convert_buffer called from clob_info_t::putOptimizeBuffer on . for .
Steps to Reproduce
Clarifying Information
Error Message
Defect/Enhancement Number
Currently for both ODBC and JDBC applications, the values for CLOB (LVARCHAR) and BLOB (LVARBINARY) columns cannot be put directly into the INSERT or UPDATE SQL statements.
Furthermore, OpenEdge SQL-92 does not support CLOB/BLOB references in a predicate (with 1 exception), function, arithmetic operator, or comparison operator. It is possible to reference a CLOB / BLOB with the IS [NOT] NULL predicate. In addition, it is not possible to use a CLOB/BLOB column as an ORDER BY or GROUP BY key.
Use a Prepared Statement to INSERT or UPDATE values for a CLOB or BLOB field as a parameter.
The following is a JDBC example for a CLOB field:

PreparedStatement pstmt = connection.prepareStatement("INSERT INTO Test (XML) VALUES (?)");
String xml = "<Tag>MyData</Tag>";
StringReader sr = new StringReader(xml);
