DM8, an error occurs in the DDL script generated for fields of the NVARCHAR type.

### Description

When connecting to DM8, an error occurs in the DDL script generated for fields of the NVARCHAR type.
For example, run the statement:
ALTER TABLE table1 MODIFY ID NVARCHAR(36) NULL;
This modifies the ID column to NVARCHAR(36). However, the subsequently generated DDL script incorrectly shows the type as NVARCHAR(144).
