query-builder

My Laravel 5 app includes a dynamic query builder for report running. I need some group by clauses in there and have run into a problem. If I use actual sql in there I can have issues as sometimes there needs to be a sql command in amongst the sql (as opposed to straightforward column names), ie - DAYNAME(table_name.date_column) . Laravel mangles this: \`DAYNAME(table_name\`.\`date_column)\` For the select part of my query I can use selectRaw, but there does not seem to be an equivaent for group by. I thought of using aliases (all the selects are aliased) but Laravel wraps them in "`"

You should use other methods - AR or raw queries ( https://github.com/yiisoft/yii2/blob/master/docs/guide/db-dao.md#basic-sql-queries ) Create command can be used directly as follows : \Yii::$app->db->createCommand("UPDATE table SET column1=:column1, column2=:column2 WHERE id=:id") -

I need to create a dynamic linq expression for a dynamic search.The basic search is working but it fails to work with collection. I am able to get the book's title and author but fails to get the required page heading. I get the exception in line "left11 = Expression.Property(page1, "Heading");" . I think the expression that i built is unable to recognise the List. How could this be possible?

I have the following sql query SELECT * FROM exams WHERE exams.id NOT IN (SELECT examId FROM testresults) how can I convert it into Laravel query builder format? Thanks. You can use whereNotIn with a closure: $result = DB::table('exams')->whereNotIn('id', function($q){ $q->select('examId')->from('testresults'); })->get(); 来源： https://stackoverflow.com/questions/28361461/laravel-query-builder-where-not-in
