📦 安装

go get github.com/kamalyes/go-sqlbuilder

🚀 快速开始

基础使用
package main

import (
    "log"
    
    "github.com/jmoiron/sqlx"
    _ "github.com/go-sql-driver/mysql"
    sqlbuilder "github.com/kamalyes/go-sqlbuilder"
)

func main() {
    // 连接数据库
    db, err := sqlx.Connect("mysql", "user:password@tcp(localhost:3306)/testdb")
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()

    // 创建Builder实例
    builder := sqlbuilder.New(db)

    // 执行查询
    var users []User
    err = builder.Table("users").
        Select("id", "name", "email").
        Where("status", 1).
        Where("age", ">", 18).
        OrderBy("created_at", "DESC").
        Limit(10).
        Find(&users)
}
带缓存的查询
import "github.com/kamalyes/go-sqlbuilder/cache"

// 创建缓存store
store := cache.NewMockStore()  // 或 cache.NewRedisStore(redisClient, "prefix:")

// 创建带缓存的Builder
cachedBuilder, _ := sqlbuilder.NewCachedBuilder(db, store, nil)

// 自动缓存查询结果
result, _ := cachedBuilder.GetCached(ctx, sql, args...)
高级查询参数
import "github.com/kamalyes/go-sqlbuilder/query"

param := query.NewParam().
    AddEQ("status", 1).
    AddGT("age", 18).
    AddLike("name", "John").
    AddIn("category", 1, 2, 3).
    AddOrder("created_at", "DESC").
    SetPage(1, 20)

whereSQL, args := param.BuildWhereClause()

Builder实例
// 连接数据库
db, err := sqlx.Connect("mysql", "user:password@tcp(host:3306)/dbname")

builder.Table("users").
    Select("id", "name", "email").
    Where("status", 1).
    Where("age", ">", 18).
    OrderBy("created_at", "DESC").
    Limit(10).
    Find(&users)

// 单条记录
var user User
builder.Table("users").Where("id", 1).First(&user)

// 获取单个值
name, _ := builder.Table("users").Where("id", 1).Value("name")

🔗 高级特性

缓存管理
import "github.com/kamalyes/go-sqlbuilder/cache"

// Redis缓存
store := cache.NewRedisConfig("localhost:6379").
    WithPrefix("myapp:").
    Build()

cachedBuilder, _ := sqlbuilder.NewCachedBuilder(db, store, nil)

// 获取带缓存的结果
result, _ := cachedBuilder.GetCached(ctx, sql, args...)

// Mock测试用缓存
mockStore := cache.NewMockStore()
错误处理

// 错误检查
if errors.IsErrorCode(err, errors.ErrorCodeKeyNotFound) {
    log.Println("缓存键未找到")
}

code := errors.GetErrorCode(err)
msg := errors.ErrorCodeString(code)
高级查询参数

// 构建复杂查询条件
param := query.NewParam().
    AddEQ("status", 1).              // status = 1
    AddGT("age", 18).                // age > 18
    AddLike("name", "John").         // name LIKE %John%
    AddIn("category", 1, 2, 3).      // category IN (1,2,3)
    AddBetween("price", 10, 100).    // price BETWEEN 10 AND 100
    AddOrder("created_at", "DESC").  // ORDER BY created_at DESC
    SetPage(1, 20)                   // LIMIT 20 OFFSET 0
