先安装好sqlite3,Golang环境
MacBook Linux Windows等系统安装sqlite3
【golang操作sqlite3】MacBook Linux 树莓派raspberrypi安装Golang环境
sqlite3基本操作
sqlite3/Users/liang/Downloads/foo.db
.databases
.quit
.exit
.tablesCREATE TABLE `userinfo` (
`uid` INTEGER PRIMARY KEY AUTOINCREMENT,
`username` VARCHAR(64) NULL,
`departname` VARCHAR(64) NULL,
`created` DATE NULL
);
CREATE TABLE `userdeatail` (
`uid` INT(10) NULL,
`intro` TEXT NULL,
`profile` TEXT NULL,
PRIMARY KEY (`uid`)
);
.schema userinfogolang操作sqlite3
package mainimport (
"database/sql"
"fmt"
_ "github.com/mattn/go-sqlite3"
)func main() {
db, err := sql.Open("sqlite3", "/Users/liang/Downloads/foo.db")

stmt, err := db.Prepare("INSERT INTO userinfo(username, departname, created) values(?,?,?)")
checkErr(err)res, err := stmt.Exec("astaxie", "部门", "2012-12-09")
