SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: ReferenceThe 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.
DBANSIWARN environment variableUse the DBANSIWARN environment variable to indicate that you want to check for HCL OneDB™ extensions to ANSI-standard SQL syntax.

DBANSIWARN environment variable

Use the DBANSIWARN environment variable to indicate that you want to check for HCL OneDB™ extensions to ANSI-standard SQL syntax.

Unlike most environment variables, you are not required to set

DBANSIWARN

to a value. You can set it to any value or to no value.

Running DB-Access with DBANSIWARN set is functionally equivalent to including the -ansi flag when you invoke DB-Access (or any HCL OneDB product that recognizes the -ansi flag) from the command line. If you set DBANSIWARN before you run DB-Access, any syntax-extension warnings are displayed on the screen within the SQL menu.

At runtime, the DBANSIWARN environment variable causes the sixth character of the sqlwarn array in the SQL Communication Area (SQLCA) to be set to W when a statement is executed that is recognized as including any HCL OneDB extension to the ANSI/ISO standard for SQL syntax.

For details on SQLCA, see the HCL OneDB ESQL/C Programmer's Manual.

After you set DBANSIWARN, HCL OneDB extension checking is automatic until you log out or unset DBANSIWARN. To turn off HCL OneDB extension checking, you can disable DBANSIWARN with this command:

unsetenv DBANSIWARN
