SQL programmingYou can use the HCL OneDB™ implementation of the SQL language to develop applications for HCL OneDB™ database servers.
Guide to SQL: SyntaxThe HCL OneDB™ Guide to SQL: Syntax describes the syntax of the statements, data types, expressions, operators, and built-in functions of the HCL OneDB™ dialect of the SQL language.
SQL statementsThis chapter describes the syntax and semantics of SQL statements that are recognized by HCL OneDB™.
CONNECT statementUse the CONNECT statement to connect to a database environment. This statement is an extension to the ANSI/ISO standard for SQL.
USER Authentication Clause
Restrictions on the User Identifier Parameter

Restrictions on the User Identifier Parameter

The connection is rejected if any of the following conditions occur:

The specified user lacks the privileges to access the database specified in the database environment.
The specified user lacks the permissions to connect to the remote host.
You supply a USER Authentication clause but omit the USING validation_var specification.

In compliance with the X/Open standard for the CONNECT statement, the preprocessor supports a CONNECT statement that has a USER Authentication clause without the USING validation_var specification. If the validation_var is not present, however, the database server rejects the connection at runtime.

On UNIX™, the user_id that you specify must be a valid login name and must exist in the /etc/passwd file. If the application connects to a remote server, the login name must exist in this file on both the local and remote database servers.

On Windows™, the user_id that you specify must be a valid login name and must exist in User Manager. If the application connects to a remote server, the login name must exist in the domain of both the client and the server.
