SQLite .mode 显示模式

.mode MODE 设置输出模式,MODE 可以是下列之一:
  • csv 逗号分隔的值

  • column 左对齐的列

  • html HTML 的 <table> 代码

  • insert TABLE 表的 SQL 插入(insert)语句

  • line 每行一个值

  • list 由 .separator 字符串分隔的值

  • tabs 由 Tab 分隔的值

  • tcl TCL 列表元素

创建表:

CREATE TABLE person(ID INTEGER PRIMARY KEY AUTOINCREMENT, NAME TEXT NOT NULL, AGE INTEGER NOT NULL, PHONE_NUMBER TEXT NOT NULL);
insert into person(NAME,AGE,PHONE_NUMBER) values('ZHANG SAN', 20, '13012345678');
insert into person(NAME,AGE,PHONE_NUMBER) values('LI SI', 22, '15055550000');
insert into person(NAME,AGE,PHONE_NUMBER) values('WANG WU', 24, '17077770000');

 

1、默认模式:list,(实际运行结果和说明写的不一样)这里是以 | 分割

sqlite> .mode
current output mode: list
sqlite> select * from person;
ID|NAME|AGE|PHONE_NUMBER
1|ZHANG SAN|20|13012345678
2|LI SI|22|15055550000
3|WANG WU|24|17077770000

2、.csv模式,该模式列间以逗号分隔

sqlite> .mode csv
sqlite> select * from person;
ID,NAME,AGE,PHONE_NUMBER
1,"ZHANG SAN",20,13012345678
2,"LI SI",22,15055550000
3,"WANG WU",24,17077770000

3、column模式,该模式最为常用,每列数据左对齐,关键字和数据用横线分隔,显示起来比较直观清晰

sqlite> .mode column
sqlite> select * from person;
ID  NAME       AGE  PHONE_NUMBER
--  ---------  ---  ------------
1   ZHANG SAN  20   13012345678
2   LI SI      22   15055550000
3   WANG WU    24   17077770000

4、html模式 该模式将表格以html格式输出

sqlite> .mode html
sqlite> select * from person;
<TR>
    <TH>ID</TH>
    <TH>NAME</TH>
    <TH>AGE</TH>
    <TH>PHONE_NUMBER</TH>
</TR>
<TR>
    <TD>1</TD>
    <TD>ZHANG SAN</TD>
    <TD>20</TD>
    <TD>13012345678</TD>
</TR>
<TR>
    <TD>2</TD>
    <TD>LI SI</TD>
    <TD>22</TD>
    <TD>15055550000</TD>
</TR>
<TR>
    <TD>3</TD>
    <TD>WANG WU</TD>
    <TD>24</TD>
    <TD>17077770000</TD>
</TR>

5、insert模式 该模式将表中每条数据以SQL语句输出

sqlite> .mode insert
sqlite> select * from person;
INSERT INTO "table"(ID,NAME,AGE,PHONE_NUMBER) VALUES(1,'ZHANG SAN',20,'13012345678');
INSERT INTO "table"(ID,NAME,AGE,PHONE_NUMBER) VALUES(2,'LI SI',22,'15055550000');
INSERT INTO "table"(ID,NAME,AGE,PHONE_NUMBER) VALUES(3,'WANG WU',24,'17077770000');

6、line模式,该模式将每行的每个值用赋值的形式输出(实例较长,只列出部分)

sqlite> .mode line
sqlite> select * from person;
          ID = 1
        NAME = ZHANG SAN
         AGE = 20
PHONE_NUMBER = 13012345678

          ID = 2
        NAME = LI SI
         AGE = 22
PHONE_NUMBER = 15055550000

          ID = 3
        NAME = WANG WU
         AGE = 24
PHONE_NUMBER = 17077770000

7、tabs模式,该模式列间以tab键分隔,注意:tab键默认占8个字符,故第一行数据的“California”占了两个tab,所以“20000.0”只能在下一个tab中输出,而第二行则是每列数据各占一个tab

sqlite> .mode tabs
sqlite> select * from person;
ID      NAME    AGE     PHONE_NUMBER
1       ZHANG SAN       20      13012345678
2       LI SI   22      15055550000
3       WANG WU 24      17077770000

8、tcl模式,该模式的关键字和各数据均用双引号引起,列间以空格分隔

sqlite> .mode tcl
sqlite> select * from person;
"ID" "NAME" "AGE" "PHONE_NUMBER"
"1" "ZHANG SAN" "20" "13012345678"
"2" "LI SI" "22" "15055550000"
"3" "WANG WU" "24" "17077770000"
