Functions ¶

func ErrorF ¶

func ErrorF(format string, params ...any) error

func KeyTo ¶

func KeyTo(key string) string

KeyTo 字段key优化

func ObjTagMap ¶

func ObjTagMap(obj any, tag string) (map[string]interface{}, error)

ObjTagMap 结构体对象依据tag获取数据转map 当结构体中存在tag字段但无值情况给nil值当tag字段类型为slice或map时将会进行json处理当tag字段类型为其他类型时,需要在对应类型上添加Value方法去重构它,该程序将会依据Value方法获取其字段值此方法将作为sqlx的Named模式将结构体转换为map使用

Types ¶

type Clause ¶

type Clause struct {
	Condition []string      // 语句(条件语句或设置语句) xxx = ? | xxx in (?) ...
	Params    []interface{} // 值
	End       bool          // 是否结束当前子句
}

Clause 子句单个块的子句为 and 当存在多子句时,使用 or 拼接

func NewClause ¶

func NewClause() Clause

NewClause 创建子句

type ColObj ¶

type ColObj interface {
	Value() any
}
