Support for GLS in HCL® OneDB® client applicationsTo connect to a database, the client application requests a connection from the database server. The database server must verify that it can access the database and establish the connection between the client and the database.

Data that a client application converts

When the code sets of two locales differ, the HCL OneDB™ client product must use code-set conversion to prevent data corruption of character data.

Code-set conversion converts the following character data elements:

Values of SQL data types:
- CHAR, VARCHAR, NCHAR, and NVARCHAR
- TEXT (the BYTE data type is not converted)
- LVARCHAR
- Character data in opaque data types (if their support functions perform the code-set conversions)
Values of character types (char, fixchar, string, and varchar)
SQL statements, both static and dynamic
SQL identifiers. These include names of columns, tables, views, prepared statements, cursors, constraints, indexes, triggers, and other database objects. For a list of SQL objects that can include non-ASCII characters in their identifiers, see Non-ASCII characters in identifiers.
