在SQl中获取一次值

Question

这是我的SQl：

$branches = DB::select('select distinct programs.id as program_id,programs.program_name as program_name,branches.id as branch_id,branches.branch_name as branch_name from programs,branches where programs.company_id=? and branches.company_id=?' ,[$company_id,$company_id]);

当我为特定的“company_id”调用branch_id / program_id时，它会多次重复相同的id。但我想只展示一次这些价值观。我能为此做些什么？

Answer 1

将您的查询更改为

select distinct programs.id as program_id,programs.program_name as program_name,branches.id as branch_id,branches.branch_name as branch_name from programs,branches where programs.company_id=? and branches.company_id=programs.company_id
