MySQL 客户端命令

Let’s understand some MySQL client commands -

MySQL sends every SQL statement issued by the user to the server for execution. There is also a set of commands that mysql interprets itself.

If When calling mysql with the "--binary-mode" option, assuming input is piped to mysql or loaded using the source command, all mysql commands are disabled except character set and delimiters in non-interactive mode.

Each command has a long form and a short form.

Long format command

The long format is not case-sensitive, and the short format is case-sensitive. The long form may be followed by an optional semicolon terminator, but the short form should not be followed by anything.

Short format commands

Use short format commands in multiple commands -line /* ... */ Comments are not supported. Shorthand commands work within a single line /*! ... */ version comments, /* ... */ optimizer hint comments as well. They are stored in the object definition.
