Sqlite3 批量导入数据

1.打开或创建数据库，在命令行中输入sqlite3 ***(***是你的数据库名)

2.创建三个表如：

CREATE TABLE "main"."Product"

(

"ID" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,

"Name" TEXT,

"ManufacturerID" INTEGER,

"Details" TEXT,

"Price" DOUBLE,

"QuantityOnHand" INTEGER,

"CoutryOfOriginID" INTEGER,

"IMAGE" TEXT

);

CREATE TABLE "main"."Country"

(

"CountryID" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,

"Country" TEXT NOT NULL

);

CREATE TABLE "main"."Manufacturer"

(

"ManufacturerID" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,

"Name" TEXT NOT NULL

);

3.批量导入数据

3.1 建一个Porducts.txt文本文件，用制表符作为字段间的分隔符

1 Widget A
1 Details of widget A
1.29 5
1 Canvas_1

2 Widget B 1
Details of Widget B
4.29 15
2 Canvas_2

3 Widget X
2 Details of Widget X
0.29 25
3 Canvas_3

3.2 给Product表导入数据

如果还没打开SQLte命令提示符，则先打开它，输入命令.separator "\t",指定制表符\t作为数据文件中字段的分隔符

接着输入.import "Product.txt" Product,即导入Product.txt 文件到Product表中

4. 建一个Conutry.txt 和Manufacturet.txt 导入方法同3
