SQLite Syntax

Syntax is a unique set of rules and guidelines. Following is a list of syntax for SQLite.

Case sensitivity:

• SQLite is not case sensitive. But, there are some commands which are case sensitive.
• For example: GLOB and glob have different meaning in SQLite statements.

Comments:

• Comments are used to add more readability in your SQLite code.
• Comments cannot be nested.
• Comments begin with two consecutive “-” characters.
• Sometimes it also appears with “/*” and extend up to and including the next “*/” character pair.
