• Set the prompt interactively. You can change your prompt interactively by using the
command. For example:

How Logging Occurs
Statement logging occurs as follows:
• Statements are logged only when executed interactively. Statements are noninteractive, for example,
when read from a file or a pipe. It is also possible to suppress statement logging by using the
[265]
batch
• logs each nonempty statement line individually.
mysql
• If a statement spans multiple lines (not including the terminating delimiter),
lines to form the complete statement, maps newlines to spaces, and logs the result, plus a delimiter.
Consequently, an input statement that spans multiple lines can be logged twice. Consider this input:
mysql> SELECT
-> 'Today is'
-> ,
-> CONCAT()
-> ;
In this case,
It also logs the complete statement, after mapping
SELECT 'Today is' ,
SELECT
'Today is'
,
CURDATE()
;
SELECT 'Today is' , CURDATE();
Controlling the History File
The

information might be written to it, such as the text of SQL statements that contain passwords. See

If you do not want to maintain a history file, first remove
