 示例的数据库表结构如下所示，相应的建表SQL：
 ```sql
 
-	CREATE TABLE `userinfo` (
-		`uid` INTEGER PRIMARY KEY AUTOINCREMENT,
-		`username` VARCHAR(64) NULL,
-		`departname` VARCHAR(64) NULL,
-		`created` DATE NULL
-	);
+CREATE 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`)
-	);
+CREATE TABLE `userdeatail` (

 ```
 看下面Go程序是如何操作数据库表数据:增删改查
 ```Go

 我们可以看到上面的代码和MySQL例子里面的代码几乎是一模一样的，唯一改变的就是导入的驱动改变了，然后调用`sql.Open`是采用了SQLite的方式打开。
