SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: ReferenceThese topics contain the reference information for the system catalog tables, data types, and environment variables of the HCL OneDB™ dialect of the SQL language, as implemented in HCL OneDB™.The HCL OneDB™ Guide to SQL: Reference contains the reference information for the system catalog tables, data types, and environment variables of the HCL OneDB™ dialect of the SQL language, as implemented in HCL OneDB™. These topics also include information about the stores_demo, sales_demo, and superstore_demo databases that are included with HCL OneDB™.
Environment variablesVarious environment variables affect the functionality of your HCL OneDB™ products. You can set environment variables that identify your terminal, specify the location of your software and define other parameters.
Environment variables in HCL OneDB™ productsThe topics that follow discuss (in alphabetic order) environment variables that HCL OneDB™ database server products and their utilities use.
TERMCAP environment variable (UNIX™)The TERMCAP environment variable is used for terminal handling. It tells DB-Access (and other character-based applications) to communicate with the termcap file instead of the terminfo directory.

TERMCAP environment variable (UNIX)

The TERMCAP environment variable is used for terminal handling. It tells DB-Access (and other character-based applications) to communicate with the termcap file instead of the terminfo directory.

setenvTERMCAPpathname

pathname: Specifies the location of the termcap file.

The termcap file contains a list of various types of terminals and their characteristics. For example, to provide DB-Access terminal-handling information, which is specified in the /usr/informix/etc/termcap file, enter the following command:

setenv TERMCAP /usr/informix/etc/termcap

You can use set TERMCAP in any of the following ways. If several termcap files exist, they have the following (descending) order of precedence:

The termcap file that you create
The termcap file that the database server supplies (that is, $INFORMIXDIR/etc/termcap)
The operating-system termcap file (that is, /etc/termcap)

If you set the TERMCAP environment variable, be sure that the INFORMIXTERM environment variable is set to termcap.

If you do not set the TERMCAP environment variable, the terminfo directory is used by default.
