mysql - 获取不带表格格式的SQL查询结果

Question

与--disable-column-names选项一样，我们是否可以选择不使用表格格式获取 SQL 查询？例如：

mysql -u username -p password  --disable-column-names --execute "select name from test"

结果如下：

-----
| A |
| B |
| C |
| D |
-----

是否可以使用如下一些 sql 程序选项修饰符来获取查询结果，而无需表格式？

我要这个：

A
B
C
D

Answer 1

将-B标志添加到mysql.

mysql -B -u username -ppassword \
    --disable-column-names \
    --execute "select name from mydb.test"

-B, --batch: Print results in nontabular output format.

--execute: Execute the statement and quit.

请注意，-B/--batch也启用了--silent开关。

Answer 2

Although the other answers work incidentally, the correct switch is actually -s which is short for --silent.

You may want to additionally specify -r for --raw output, which disables character escaping as well, otherwise newline, tab, null char and backslash will be represented as \n, \t, \0 and \ respectively.

   ·   --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)
           \
