New namespace added: DATATYPE_SAMPLE
This sample database is designed to analyze error scenarios in which column values do not conform to the data types and constraints defined in the metadata. The goal is to understand and evaluate the behavior of the database and associated drivers (JDBC, ODBC, .NET) in such cases.
When tables are created and modified exclusively via SQL, inconsistencies between data and metadata should be practically impossible. Even when accessing the database through object layer, proper validation is expected to enforce metadata compliance.
However, inconsistencies like those demonstrated here can occur when applications used direct Global Access, potentially bypassing built-in protections such as type checks or constraint enforcement. This is especially relevant in legacy systems.
