Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.

Database server featuresThese topics describe how the GLS feature affects the database server.
Locale support for C User-defined routines (HCL OneDB™ and DB API)HCL OneDB™ allows you to create user-defined routines (UDRs) that are written in the C programming language.
Code-set conversion and the DataBlade® APIWithin a UDR, the DataBlade® API does not perform any code-set conversion automatically.
Character strings in UDRsWhen your C UDR contains character strings that are sent to the database server, it must perform any required code-set conversion on these strings.

Character strings in UDRs

When your C UDR contains character strings that are sent to the database server, it must perform any required code-set conversion on these strings.

This code-set conversion must handle any differences between the code set of this character string and the code set of the server-processing locale in which the UDR executes.

For example, the DataBlade® API does not perform code-set conversion on the multibyte table name, A¹A²A³B¹B², in the following SELECT statement:

mi_exec(conn, "SELECT * from A¹A²A³B¹B²", 0);

If your UDR might execute in a server-processing locale that does not include a code set that supports characters in your SQL statements, the UDR can explicitly perform code-set conversion between the code sets of the server-processing locale and a specified locale.
