在damishop企业版中使用laravel的Illuminate\Database

追影

1. $info = $this->capsule::table('product')->where('product_id',29)->first();

复制代码

模型或控制器中都可以直接使用$this->capsule

查询方法
Illuminate\Database\Query\Builder 类包含如下公用方法:

查询

select($columns = ['*'])

selectSub($query, $as)

selectRaw($expression, array $bindings = [])

addSelect($column)

from($table, $as = null)

fromSub($query, $as)

fromRaw($expression, $bindings = [])

去重

distinct()

连接

join($table, $first, $operator = null, $second = null, $type = 'inner', $where = false)

joinSub($query, $as, $first, $operator = null, $second = null, $type = 'inner', $where = false)

joinWhere($table, $first, $operator, $second, $type = 'inner')

leftJoin($table, $first, $operator = null, $second = null)

leftJoinWhere($table, $first, $operator, $second)

leftJoinSub($query, $as, $first, $operator = null, $second = null)

rightJoin($table, $first, $operator = null, $second = null)

rightJoinWhere($table, $first, $operator, $second)

rightJoinSub($query, $as, $first, $operator = null, $second = null)

crossJoin($table, $first = null, $operator = null, $second = null)

crossJoinSub($query, $as)
