Syntax Notation 
The syntax notation used in the documentation is derived from the Backus Naur Form (BNF). The following conventions, among others, apply:
Syntax Element |
Description |
KEYWORD |
Keyword
Keywords are shown in uppercase letters for the sake of emphasis. If there is no specific reference to case-sensitivity in the documentation, you can write keywords in either upper- or lowercase letters. |
<variable> |
Placeholders for syntax elements, such as variables
When you enter the variable, you do not enter the angle brackets. |
[syntax_element] |
Optional syntax element |
syntax_element1 | syntax_element1 |
Alternative syntax elements (or) |
syntax_element, ... |
Syntax element can be repeated as often as required. |
To make the documentation easier to use, the syntax is formatted as follows:
Example |
Description |
>dbmcli db_enum |
Commands and SQL statements that users should enter |
OK DEMODB |
Output of the database system, the database tools or other programs |
The command db_enum lists all database instances. The documentation uses the demo database instance DEMODB. |
Syntax elements and examples in continuous text |
Example
>sqlcli –d <database_name> –u <database_user>,<database_user_password> <sql_statement>
To illustrate commands and actions, the documentation uses the DEMODB demo database instance and the HOTEL schema sample data found there:
>sqlcli –d demodb -u mona,red SELECT * FROM hotel.city
