laravel 中 in 多列特殊查询类型解决方案

作者: guanguans | 来源:发表于2022-07-05 15:00 被阅读0次

    SQL 查询中有一种 in 多列特殊查询类型,大概是这个样子 select * from order where (id,buyer) in(( 1, '张三' ),( 2, '李四' )) and order.deleted_at is null。laravel 的查询构建器并没有直接支持该类型的查询。我这边通过查询构建器 Macroable 新增了一个 whereIns 查询方法方便该类型的查询。

    使用示例

    <?php
    
    use App\Models\Order;
    
    Order::query()
        // ->whereRaw("(id,buyer) in(( 1, '张三' ),( 2, '李四' ))")
        ->whereIns(['id', 'buyer'], [
            ['buyer' => '张三', 'id' => 1],
            [2, '李四']
        ])
        ->dump()
        ->get();
    
    // "select * from `order` where (id,buyer) in ((?,?),(?,?)) and `order`.`deleted_at` is null"
    // array:4 [
    //   0 => 1
    //   1 => "张三"
    //   2 => 2
    //   3 => "李四"
    // ]
    

    新建 QueryBuilderMacro

    <?php
    
    namespace App\Support\Macros;
    
    use Illuminate\Contracts\Support\Arrayable;
    
    class QueryBuilderMacro
    {
        public function whereIns(): callable
        {
            /* @var Arrayable|array[] $values */
            return function (array $columns, $values, string $boolean = 'and', bool $not = false) {
                /** @var \Illuminate\Database\Eloquent\Builder $this */
                $type = $not ? 'not in' : 'in';
    
                $rawColumns = implode(',', $columns);
    
                $values instanceof Arrayable and $values = $values->toArray();
                $values = array_map(function ($value) use ($columns) {
                    if (array_is_list($value)) {
                        return $value;
                    }
    
                    return array_reduce($columns, function ($sortedValue, $column) use ($value) {
                        $sortedValue[$column] = $value[$column] ?? trigger_error(
                            sprintf(
                                '%s: %s',
                                'The value of the column is not found in the array.',
                                $column
                            ),
                            E_USER_ERROR
                        );
    
                        return $sortedValue;
                    }, []);
                }, $values);
    
                $rawValue = sprintf('(%s)', implode(',', array_fill(0, count($columns), '?')));
                $rawValues = implode(',', array_fill(0, count($values), $rawValue));
    
                $raw = "($rawColumns) $type ($rawValues)";
    
                return $this->whereRaw($raw, $values, $boolean);
            };
        }
    
        public function whereNotIns(): callable
        {
            return function (array $columns, $values) {
                /** @var \Illuminate\Database\Eloquent\Builder $this */
                return $this->whereIns($columns, $values, 'and', true);
            };
        }
    
        public function orWhereIns(): callable
        {
            return function (array $columns, $values) {
                /** @var \Illuminate\Database\Eloquent\Builder $this */
                return $this->whereIns($columns, $values, 'or');
            };
        }
    
        public function orWhereNotIns(): callable
        {
            return function (array $columns, $values) {
                /** @var \Illuminate\Database\Eloquent\Builder $this */
                return $this->whereIns($columns, $values, 'or', true);
            };
        }
    }
    

    AppServiceProvider 注册 QueryBuilderMacro 即可

    <?php
    
    namespace App\Providers;
    
    use App\Support\Macros\QueryBuilderMacro;
    use Illuminate\Database\Eloquent\Builder as EloquentBuilder;
    use Illuminate\Database\Eloquent\Relations\Relation;
    use Illuminate\Database\Query\Builder as QueryBuilder;
    use Illuminate\Support\ServiceProvider;
    
    class AppServiceProvider extends ServiceProvider
    {
        ...
        public function boot()
        {
            QueryBuilder::mixin($queryBuilderMacro = $this->app->make(QueryBuilderMacro::class));
            EloquentBuilder::mixin($queryBuilderMacro);
            Relation::mixin($queryBuilderMacro);
        }
        ...
    }
