gorm 條件模式

條件比較靈活,能夠用於 db.Frist, db.Last, db.Find, db.Where 等方法。

單個整數

指定主鍵id

3

sql: id = 3

一組整數

指定一組主鍵id

[]int{1,2,3}

sql: id in (1,2,3)

字符串開頭，後跟參數

簡單 sql

"age = ?", 11

sql: age = 11

"name = ?", "user1"

sql: name = "user1"

結構

將只查詢具備值的那些字段

&User{Name: "user1", Age: 12}

sql: name = "user1" AND age = 12

映射 map[string]interface{}

map[string]interface{}{"name": "user1", "age": 12}

sql: name = "user1" AND age = 12
