Client APIs and toolsYou can use the HCL OneDB™ implementation of client APIs to develop applications for HCL OneDB™ database servers.
ESQL/C GuideThe topics explain how to use HCL OneDB™ ESQL/C, the HCL OneDB™ implementation of Embedded Structured Query Language (SQL) for C (ESQL/C), to create client applications with database-management capabilities. The HCL® OneDB® ESQL/C Programmer's Manual explains how to use HCL OneDB™ ESQL/C, the HCL OneDB™ implementation of Embedded Structured Query Language (SQL) for C (ESQL/C), to create client applications with database-management capabilities.
What is HCL OneDB™ ESQL/C?
Compile programs
Compiling and linking options of the esql command
Name the executable fileYou can explicitly specify the name of the executable file with the -o option.

Name the executable file

You can explicitly specify the name of the executable file with the -o option.

For example, the following esql command produces an executable file called inpt:

esql -o inpt custinpt.ec ordinpt.ec

If esql is running on a Windows™ operating system, the name of the target file defaults to the name of the first HCL OneDB™ ESQL/C source file on the esql command line. The extension is changed to either .exe or .dll depending on the type of target being generated.

If esql is running on a UNIX™ operating system, the name of the target file defaults to whatever is the default for your C compiler, usually a.out.
