像--disable-column-names
option一样,我们是否可以选择不使用表格式的sql查询?
例:
mysql -u username -ppassword --disable-column-names --execute "select name from test"
结果如下:
-----
| A |
| B |
| C |
| D |
-----
是否可以使用以下某些sql程序选项修饰符来获得查询结果,[没有表格式]
A
B
C
D
Answers:
向中添加-B
选项mysql
。
mysql -B -u username -ppassword \
--disable-column-names \
--execute "select name from mydb.test"
-B,-- batch :以非表格输出格式打印结果。
--execute:执行该语句并退出。

编辑:感谢@ joescii,-B
它是的缩写--batch
,也启用了该--silent
开关。
-b
已弃用,请--batch
改用。
--database <database-name>
选项添加到命令行是一个好主意。
尽管其他答案偶然起作用,但实际上正确的开关-s
是的缩写--silent
。
您可能需要另外指定-r
为--raw
输出,即禁用字符转义为好,否则换行符,制表符,零炭和反斜杠将分别被表示为\ N,\吨,\ 0和\。
· --silent, -s Silent mode. Produce less output. This option can be given multiple times to produce less and less output. This option results in nontabular output format and escaping of special characters. Escaping may be disabled by using raw mode; see the description for the --raw option. · --raw, -r For tabular output, the “boxing” around columns enables one column value to be distinguished from another. For nontabular output (such as is produced in batch mode or when the --batch or --silent option is given), special characters are escaped in the output so they can be identified easily. Newline, tab, NUL, and backslash are written as \n, \t, \0, and \\. The --raw option disables this character escaping. The following example demonstrates tabular versus nontabular output and the use of raw mode to disable escaping: % mysql mysql> SELECT CHAR(92); +----------+ | CHAR(92) | +----------+ | \ | +----------+ % mysql -s mysql> SELECT CHAR(92); CHAR(92) \\ % mysql -s -r mysql> SELECT CHAR(92); CHAR(92) \
