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 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.
