Go & SQLite on Windows

一般golang使用的sqlite驱动包都是github.com/mattn/go-sqlite3，但是官方并没有直接支持windows平台的编译，因为windows平台编译默认需要gcc支持

其实解决办法很简单，只需要在windows平台下安装gcc即可正常使用。

编译错误如下:

go get github.com/mattn/go-sqlite3

# github.com/mattn/go-sqlite3

exec: "gcc": executable file not found in %PATH%

下面说明如何解决:

1. 下载GCC http://tdm-gcc.tdragon.net/download

2. 安装GCC

3. 打开MinGW Command Prompt 安装sqlite3

go get github.com/mattn/go-sqlite3

4. 安装好就可以测试程序了

package main

import (

    "database/sql"

    "fmt"

    _ "github.com/mattn/go-sqlite3"

)

func main() {

    //1. Open connection

    db, err := sql.Open("sqlite3", ":memory:")

    checkErr(err)

    defer db.Close()

    //2. fail-fast if can't connect to DB

    checkErr(db.Ping())

    //3. create table

    _, err = db.Exec("create table USER (ID integer PRIMARY KEY, NAME string not null); delete from USER;")

    checkErr(err)

    //4. insert data

    //4.1 Begin transaction

    tx, err := db.Begin()

    checkErr(err)

    //4.2 Prepare insert stmt.

    stmt, err := tx.Prepare("insert into USER(ID, NAME) values(?, ?)")

    checkErr(err)

    defer stmt.Close()

    for i := ; i < ; i++ {

        _, err = stmt.Exec(i, fmt.Sprint("user-", i))

        checkErr(err)

    }

    //4.3 Commit transaction

    tx.Commit()

    //5. Query data

    rows, err := db.Query("select * from USER")

    checkErr(err)

    defer rows.Close()

    //5.1 Iterate through result set

    for rows.Next() {

        var name string

        var id int

        err := rows.Scan(&id, &name)

        checkErr(err)

        fmt.Printf("id=%d, name=%s\n", id, name)

    }

    //5.2 check error, if any, that were encountered during iteration

    err = rows.Err()

    checkErr(err)

}

func checkErr(err error, args ...string) {

    if err != nil {

        fmt.Println("Error")

        fmt.Println("%q: %s", err, args)

    }

}
