pagination

问题 I am trying to do a simple pagination of a query that uses a view: DB::table('vw_myview')->paginate(50) And get this error: SQLSTATE[42000]: Syntax error or access violation: 1140 Mixing of GROUP columns (MIN(),MAX(),COUNT(),...) with no GROUP columns is illegal if there is no GROUP BY clause (SQL: select count(*) as aggregate from vw_myview) Yet when I manually run the query, it works just fine: mysql> select count(*) as aggregate from vw_myview; +-----------+ | aggregate | +-----------+ |

问题 I want to implement pagination using aws s3. There are 500 files in object ms.files but i want to retrieve only 20 files at a time and next 20 next time and so on. var params = { Bucket: 'mystore.in', Delimiter: '/', Prefix: '/s/ms.files/', Marker:'images', }; s3.listObjects(params, function(err, data) { if (err) console.log(err, err.stack); else console.log(data); }); 回答1: Came across this while looking to list all of the objects at once, if your response is truncated it gives you a flag

问题 I have a simple query as follows "select * from USERS". I also use Pageable to enable pagination. This query may have optional predicates based on the given parameters being null or not. For example if "code" parameter is given and not null, then the query becomes "select * from USERS where code = :code"; As far as I know I cannot implement this using @Query annotation.
