* How the xorm tag use both with json?
|
||||
|
||||
Use space.
|
||||
|
||||
```Go
|
||||
type User struct {
|
||||
Name string `json:"name" xorm:"name"`
|
||||
}
|
||||
```
|
||||
|
||||
* Does xorm support composite primary key?
|
||||
|
||||
Yes. You can use pk tag. All fields have tag will as one primary key by fields order on struct. When use, you can use xorm.PK{1, 2}. For example: `Id(xorm.PK{1, 2})`.
|
||||
|
||||
* How to use join？
|
||||
|
||||
We can use Join() and extends tag to do join operation. For example:
|
||||
|
||||
type Userinfo struct {
|
||||
Id int64
|
||||
Name string
|
||||
DetailId int64
|
||||
}
|
||||
|
||||
type Userdetail struct {
|
||||
Id int64
|
||||
Gender int
|
||||
}
|
||||
|
||||
type User struct {
|
||||
Userinfo `xorm:"extends"`
|
||||
Userdetail `xorm:"extends"`
|
||||
}
|
||||
|
||||
var users = make([]User, 0)
|
||||
err := engine.Table(&Userinfo{}).Join("LEFT", "userdetail", "userinfo.detail_id = userdetail.id").Find(&users)
|
||||
|
||||
//assert(User.Userinfo.Id != 0 && User.Userdetail.Id != 0)
|
||||
|
||||
Please notice that Userinfo field on User should be before Userdetail because of the order on join SQL stsatement. If the order is wrong, the same name field may be set a wrong value.
|
||||
|
||||
Of course, If join statment is very long, you could directly use Sql():
|
||||
|
||||
err := engine.Sql("select * from userinfo, userdetail where userinfo.detail_id = userdetail.id").Find(&users)
|
||||
|
||||
//assert(User.Userinfo.Id != 0 && User.Userdetail.Id != 0)

### 5.1. Chainable APIs for Queries, Execusions and Aggregations
|
||||
|
||||
Queries and Aggregations is basically formed by using `Get`, `Find`, `Count` methods, with conjunction of following chainable APIs to form conditions, grouping and ordering:

查询和统计主要使用`Get`, `Find`, `Count`三个方法。在进行查询时可以使用多个方法来形成查询条件，条件函数如下：
|

* Id([]interface{})

Primary Key lookup

### 6.1.Optimistic Lock
|
||||
|
||||
To enable object optimistic lock, add 'version' tag value:
|
||||
```Go
|
||||
type User struct {
|
||||
Id int64
|
||||
Name string
|
||||
Version int `xorm:"version"`
|
||||
}
|
||||
|
||||
```
|
||||
The version starts with 1 when inserted to DB. For updating make sure originated version value is used for optimistic lock check.

## 15.FAQ
|
||||
|
||||
* How the xorm tag use both with json?
|
||||
|
||||
Use space.
|
||||
|
||||
```Go
|
||||
type User struct {
|
||||
Name string `json:"name" xorm:"name"`
|
||||
}
|
||||
```
|
||||
|
||||
* Does xorm support composite primary key?
|
||||
|
||||
Yes. You can use pk tag. All fields have tag will as one primary key by fields order on struct. When use, you can use xorm.PK{1, 2}. For example: `Id(xorm.PK{1, 2})`.
|
||||
|
||||
* How to use join？
|
||||
|
||||
We can use Join() and extends tag to do join operation. For example:
|
||||
|
||||
type Userinfo struct {
|
||||
Id int64
|
||||
Name string
|
||||
DetailId int64
|
||||
}
|
||||
|
||||
type Userdetail struct {
|
||||
Id int64
|
||||
Gender int
|
||||
}
|
||||
|
||||
type User struct {
|
||||
Userinfo `xorm:"extends"`
|
||||
Userdetail `xorm:"extends"`
|
||||
}
|
||||
|
||||
var users = make([]User, 0)
|
||||
err := engine.Table(&Userinfo{}).Join("LEFT", "userdetail", "userinfo.detail_id = userdetail.id").Find(&users)
|
||||
|
||||
//assert(User.Userinfo.Id != 0 && User.Userdetail.Id != 0)
|
||||
|
||||
Please notice that Userinfo field on User should be before Userdetail because of the order on join SQL stsatement. If the order is wrong, the same name field may be set a wrong value.
|
||||
|
||||
Of course, If join statment is very long, you could directly use Sql():
|
||||
|
||||
err := engine.Sql("select * from userinfo, userdetail where userinfo.detail_id = userdetail.id").Find(&users)
|
||||
|
||||
//assert(User.Userinfo.Id != 0 && User.Userdetail.Id != 0)

# xorm tools
|
||||
|
||||
xorm tools is a set of tools for database operation.
|
||||
|
||||
## Binary Install
|
||||
|
||||
If you have [got](https://github.com/gobuild/got) installed, you can install by got
|
||||
|
||||
```
|
||||
got go-xorm/cmd/xorm
|
||||
```
|
||||
|
||||
or you can download from [gobuild](http://gobuild.io/download/github.com/lunny/got).
|
||||
|
||||
## Source Install
|
||||
|
||||
`go get github.com/go-xorm/cmd/xorm`
|
||||
|
||||
and you should install the depends below:
|
||||
|
||||
* github.com/go-xorm/xorm
|
||||
|
||||
* Mysql: [github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql)
|
||||
|
||||
* MyMysql: [github.com/ziutek/mymysql/godrv](https://github.com/ziutek/mymysql/godrv)
|
||||
|
||||
* Postgres: [github.com/lib/pq](https://github.com/lib/pq)
|
||||
|
||||
* SQLite: [github.com/mattn/go-sqlite3](https://github.com/mattn/go-sqlite3)
|
||||
|
||||
** For sqlite support, you need build via `go build -tags sqlite3` because of this driver ask cgo.
|
||||
|
||||
## Commands
|
||||
|
||||
All the commands below.
|
||||
|
||||
* **reverse** reverse a db to codes
|
||||
* **shell** a general shell to operate all kinds of database
|
||||
* **dump** dump database all table struct's and data to standard output
|
||||
* **source** execute a sql from std in
|
||||
* **driver** list all supported drivers
|
||||
|
||||
## Reverse
|
||||
|
||||
Reverse command is a tool to convert your database struct to all kinds languages of structs or classes. After you installed the tool, you can type
|
||||
|
||||
`xorm help reverse`
|
||||
|
||||
to get help
|
||||
|
||||
example:
|
||||
|
||||
sqlite:
|
||||
`xorm reverse sqite3 test.db templates/goxorm`
|
||||
|
||||
mysql:
|
||||
`xorm reverse mysql root:@/xorm_test?charset=utf8 templates/goxorm`
|
||||
|
||||
mymysql:
|
||||
`xorm reverse mymysql xorm_test2/root/ templates/goxorm`
|
||||
|
||||
postgres:
|
||||
`xorm reverse postgres "dbname=xorm_test sslmode=disable" templates/goxorm`
|
||||
|
||||
will generated go files in `./model` directory
|
||||
|
||||
### Template and Config
|
||||
|
||||
Now, xorm tool supports go and c++ two languages and have go, goxorm, c++ three of default templates. In template directory, we can put a config file to control how to generating.
|
||||
|
||||
````
|
||||
lang=go
|
||||
genJson=1
|
||||
```
|
||||
|
||||
lang must be go or c++ now.
|
||||
genJson can be 1 or 0, if 1 then the struct will have json tag.
|
||||
|
||||
## Shell
|
||||
|
||||
Shell command provides a tool to operate database. For example, you can create table, alter table, insert data, delete data and etc.
|
||||
|
||||
`xorm shell sqlite3 test.db` will connect to the sqlite3 database and you can type `help` to list all the shell commands.
|
||||
|
||||
## Dump
|
||||
|
||||
Dump command provides a tool to dump all database structs and data as SQL to your standard output.
|
||||
|
||||
`xorm dump sqlite3 test.db` could dump sqlite3 database test.db to standard output. If you want to save to file, just
|
||||
type `xorm dump sqlite3 test.db > test.sql`.
|
||||
|
||||
## Source
|
||||
|
||||
`xorm source sqlite3 test.db < test.sql` will execute sql file on the test.db.
|
||||
|
||||
## Driver
|
||||
|
||||
List all supported drivers since default build will not include sqlite3.

|

* 怎么同时使用xorm的tag和json的tag？
|
||||
|
||||
答：使用空格
|
||||
|
||||
```Go
|
||||
type User struct {
|
||||
Name string `json:"name" xorm:"name"`
|
||||
}
|
||||
```
|
||||
|
||||
* 我的struct里面包含bool类型，为什么它不能作为条件也没法用Update更新？
|
||||
|
||||
答：默认bool类型因为无法判断是否为空，所以不会自动作为条件也不会作为Update的内容。可以使用UseBool函数，也可以使用Cols函数
|
||||
|
||||
```Go
|
||||
engine.Cols("bool_field").Update(&Struct{BoolField:true})
|
||||
// UPDATE struct SET bool_field = true
|
||||
```
|
||||
|
||||
* 我的struct里面包含float64和float32类型，为什么用他们作为查询条件总是不正确？
|
||||
|
||||
答：默认float32和float64映射到数据库中为float,real,double这几种类型，这几种数据库类型数据库的实现一般都是非精确的。因此作为相等条件查询有可能不会返回正确的结果。如果一定要作为查询条件，请将数据库中的类型定义为Numeric或者Decimal。
|
||||
|
||||
```Go
|
||||
type account struct {
|
||||
money float64 `xorm:"Numeric"`
|
||||
}
|
||||
```
|
||||
|
||||
* 为什么Update时Sqlite3返回的affected和其它数据库不一样？
|
||||
|
||||
答：Sqlite3默认Update时返回的是update的查询条件的记录数条数，不管记录是否真的有更新。而Mysql和Postgres默认情况下都是只返回记录中有字段改变的记录数。
|
||||
|
||||
* xorm有几种命名映射规则？
|
||||
|
||||
答：目前支持SnakeMapper和SameMapper两种。SnakeMapper支持结构体和成员以驼峰式命名而数据库表和字段以下划线连接命名；SameMapper支持结构体和数据库的命名保持一致的映射。
|
||||
|
||||
* xorm支持复合主键吗？
|
||||
|
||||
答：支持。在定义时，如果有多个字段标记了pk，则这些字段自动成为复合主键，顺序为在struct中出现的顺序。在使用Id方法时，可以用`Id(xorm.PK{1, 2})`的方式来用。
|
||||
|
||||
* xorm如何使用Join？
|
||||
|
||||
答：一般我们配合Join()和extends标记来进行，比如我们要对两个表进行Join操作，我们可以这样：
|
||||
|
||||
type Userinfo struct {
|
||||
Id int64
|
||||
Name string
|
||||
DetailId int64
|
||||
}
|
||||
|
||||
type Userdetail struct {
|
||||
Id int64
|
||||
Gender int
|
||||
}
|
||||
|
||||
type User struct {
|
||||
Userinfo `xorm:"extends"`
|
||||
Userdetail `xorm:"extends"`
|
||||
}
|
||||
|
||||
var users = make([]User, 0)
|
||||
err := engine.Table(&Userinfo{}).Join("LEFT", "userdetail", "userinfo.detail_id = userdetail.id").Find(&users)
|
||||
|
||||
请注意这里的Userinfo在User中的位置必须在Userdetail的前面，因为他在join语句中的顺序在userdetail前面。如果顺序不对，那么对于同名的列，有可能会赋值出错。
|
||||
|
||||
当然，如果Join语句比较复杂，我们也可以直接用Sql函数
|

## 16.那些年我们踩过的坑
|
||||
* 怎么同时使用xorm的tag和json的tag？
|
||||
|
||||
答：使用空格
|
||||
|
||||
```Go
|
||||
type User struct {
|
||||
Name string `json:"name" xorm:"name"`
|
||||
}
|
||||
```
|
||||
|
||||
* 我的struct里面包含bool类型，为什么它不能作为条件也没法用Update更新？
|
||||
|
||||
答：默认bool类型因为无法判断是否为空，所以不会自动作为条件也不会作为Update的内容。可以使用UseBool函数，也可以使用Cols函数
|
||||
|
||||
```Go
|
||||
engine.Cols("bool_field").Update(&Struct{BoolField:true})
|
||||
// UPDATE struct SET bool_field = true
|
||||
```
|
||||
|
||||
* 我的struct里面包含float64和float32类型，为什么用他们作为查询条件总是不正确？
|
||||
|
||||
答：默认float32和float64映射到数据库中为float,real,double这几种类型，这几种数据库类型数据库的实现一般都是非精确的。因此作为相等条件查询有可能不会返回正确的结果。如果一定要作为查询条件，请将数据库中的类型定义为Numeric或者Decimal。
|
||||
|
||||
```Go
|
||||
type account struct {
|
||||
money float64 `xorm:"Numeric"`
|
||||
}
|
||||
```
|
||||
|
||||
* 为什么Update时Sqlite3返回的affected和其它数据库不一样？
|
||||
|
||||
答：Sqlite3默认Update时返回的是update的查询条件的记录数条数，不管记录是否真的有更新。而Mysql和Postgres默认情况下都是只返回记录中有字段改变的记录数。
|
||||
|
||||
* xorm有几种命名映射规则？
|
||||
|
||||
答：目前支持SnakeMapper和SameMapper两种。SnakeMapper支持结构体和成员以驼峰式命名而数据库表和字段以下划线连接命名；SameMapper支持结构体和数据库的命名保持一致的映射。
|
||||
|
||||
* xorm支持复合主键吗？
|
||||
|
||||
答：支持。在定义时，如果有多个字段标记了pk，则这些字段自动成为复合主键，顺序为在struct中出现的顺序。在使用Id方法时，可以用`Id(xorm.PK{1, 2})`的方式来用。
|
||||
|
||||
* xorm如何使用Join？
|
||||
|
||||
答：一般我们配合Join()和extends标记来进行，比如我们要对两个表进行Join操作，我们可以这样：
|
||||
|
||||
type Userinfo struct {
|
||||
Id int64
|
||||
Name string
|
||||
DetailId int64
|
||||
}
|
||||
|
||||
type Userdetail struct {
|
||||
Id int64
|
||||
Gender int
|
||||
}
|
||||
|
||||
type User struct {
|
||||
Userinfo `xorm:"extends"`
|
||||
Userdetail `xorm:"extends"`
|
||||
}
|
||||
|
||||
var users = make([]User, 0)
|
||||
err := engine.Table(&Userinfo{}).Join("LEFT", "userdetail", "userinfo.detail_id = userdetail.id").Find(&users)
|
||||
|
||||
请注意这里的Userinfo在User中的位置必须在Userdetail的前面，因为他在join语句中的顺序在userdetail前面。如果顺序不对，那么对于同名的列，有可能会赋值出错。
|
||||
|
||||
当然，如果Join语句比较复杂，我们也可以直接用Sql函数
|
||||
|
||||
err := engine.Sql("select * from userinfo, userdetail where userinfo.detail_id = userdetail.id").Find(&users)

# xorm 工具
|
||||
|
||||
xorm 是一组数据库操作命令行工具。
|
||||
|
||||
## 二进制安装
|
||||
|
||||
如果你安装了 [got](https://github.com/gobuild/got)，你可以输入如下命令安装：
|
||||
|
||||
```
|
||||
got go-xorm/cmd/xorm
|
||||
```
|
||||
|
||||
或者你可以从 [gobuild](http://gobuild.io/download/github.com/lunny/got) 下载后解压到可执行路径。
|
||||
|
||||
## 源码安装
|
||||
|
||||
`go get github.com/go-xorm/cmd/xorm`
|
||||
|
||||
同时你需要安装如下依赖:
|
||||
|
||||
* github.com/go-xorm/xorm
|
||||
|
||||
* Mysql: [github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql)
|
||||
|
||||
* MyMysql: [github.com/ziutek/mymysql/godrv](https://github.com/ziutek/mymysql/godrv)
|
||||
|
||||
* Postgres: [github.com/lib/pq](https://github.com/lib/pq)
|
||||
|
||||
* SQLite: [github.com/mattn/go-sqlite3](https://github.com/mattn/go-sqlite3)
|
||||
|
||||
** 对于sqlite3的支持，你需要自己进行编译 `go build -tags sqlite3` 因为sqlite3需要cgo的支持。
|
||||
|
||||
## 命令列表
|
||||
|
||||
有如下可用的命令：
|
||||
|
||||
* **reverse** 反转一个数据库结构，生成代码
|
||||
* **shell** 通用的数据库操作客户端，可对数据库结构和数据操作
|
||||
* **dump** Dump数据库中所有结构和数据到标准输出
|
||||
* **source** 从标注输入中执行SQL文件
|
||||
* **driver** 列出所有支持的数据库驱动
|
||||
|
||||
## reverse
|
||||
|
||||
Reverse command is a tool to convert your database struct to all kinds languages of structs or classes. After you installed the tool, you can type
|
||||
|
||||
`xorm help reverse`
|
||||
|
||||
to get help
|
||||
|
||||
example:
|
||||
|
||||
sqlite:
|
||||
`xorm reverse sqite3 test.db templates/goxorm`
|
||||
|
||||
mysql:
|
||||
`xorm reverse mysql root:@/xorm_test?charset=utf8 templates/goxorm`
|
||||
|
||||
mymysql:
|
||||
`xorm reverse mymysql xorm_test2/root/ templates/goxorm`
|
||||
|
||||
postgres:
|
||||
`xorm reverse postgres "dbname=xorm_test sslmode=disable" templates/goxorm`
|
||||
|
||||
will generated go files in `./model` directory
|
||||
|
||||
### Template and Config
|
||||
|
||||
Now, xorm tool supports go and c++ two languages and have go, goxorm, c++ three of default templates. In template directory, we can put a config file to control how to generating.
|
||||
|
||||
````
|
||||
lang=go
|
||||
genJson=1
|
||||
```
|
||||
|
||||
lang must be go or c++ now.
|
||||
genJson can be 1 or 0, if 1 then the struct will have json tag.
|
||||
|
||||
## Shell
|
||||
|
||||
Shell command provides a tool to operate database. For example, you can create table, alter table, insert data, delete data and etc.
|
||||
|
||||
`xorm shell sqlite3 test.db` will connect to the sqlite3 database and you can type `help` to list all the shell commands.
|
||||
|
||||
## Dump
|
||||
|
||||
Dump command provides a tool to dump all database structs and data as SQL to your standard output.
|
||||
|
||||
`xorm dump sqlite3 test.db` could dump sqlite3 database test.db to standard output. If you want to save to file, just
|
||||
type `xorm dump sqlite3 test.db > test.sql`.
|
||||
|
||||
## Source
|
||||
|
||||
`xorm source sqlite3 test.db < test.sql` will execute sql file on the test.db.
|
||||
|
||||
## Driver
|
||||
|
||||
List all supported drivers since default build will not include sqlite3.
