sqlite>
默认的分隔符是"|".
示例5:
你可以通过".separator"来设置"list"模式下的分隔符。比如我们想把","作为分隔符,可以这样:
示例6:
比如,示例7
sqlite>.mode line
sqlite>
select * from tbl1;
one = hello
two = 10
one = goodbye
two = 20
sqlite>
比如,
示例8:
sqlite>.mode column
sqlite>
select * from tbl1;
one two
---------- ----------
hello 10
goodbye 20
sqlite>
但是
我们可以通过".width"设置每列的宽度
。
比如,
示例9:
sqlite>
.width 12 6
sqlite>
select * from tbl1;
one two
------------ ------
hello 10
goodbye 20
sqlite>
示例9就把第1列和第二列的宽度分别设置为了12和6个字符,其他列的宽度并没改变。
如果你把列宽设置为0,那么调整为以下三个的最大值:10,该列的列名字符数,第一行记录该列的字符数。这样列的宽度就可以自动调整。
默认的列宽就是0,以便它可以自动调整
。
比如,
示例10:
比如,
示例11:
sqlite>
.mode insert new_table
sqlite>
select * from tbl1;
INSERT INTO 'new_table' VALUES('hello',10);
INSERT INTO 'new_table' VALUES('goodbye',20);
sqlite>
它并不以<TABLE>作为开头和</TABLE>作为结尾。 但是每条记录以<TR>作为开始,</TR>作为结束,记录的数据以<TD>作为开始,以</TD>作为结束
比如,
示例12:
sqlite>
select * from system;
select * from system;
<TR><TD>1</TD>
<TD>volume_music</TD>
<TD>7</TD>
</TR>
<TR><TD>4</TD>
<TD>volume_voice</TD>
<TD>4</TD>
</TR>
........省略.........
