我有 2 个变量:一个存储表的内容,一个存储检查数据库中所有键的 sql 脚本。$indexes = DB::connection('sqlsrv2')->table('indexes')->get();$dbIndexes = DB::connection('sqlsrv')->select (" select schema_name(t.[schema_id]) + '.' + t.[name] as table_view, substring(column_names, 1, len(column_names)-1) as [columns], case when i.is_primary_key = 1 then 'Primary_key' when i.is_unique = 1 then 'Unique' else 'Not_unique' end as [type], i.[name] as index_name, i.index_id from sys.objects t inner join sys.indexes i on t.[object_id] = i.[object_id] cross apply ( select col.[name] + ', ' from sys.index_columns ic inner join sys.columns col on ic.[object_id] = col.[object_id] and ic.column_id = col.column_id where ic.[object_id] = t.[object_id] and ic.index_id = i.index_id order by col.column_id for xml path ('') ) D (column_names) where t.is_ms_shipped <> 1 and index_id > 0 ");我需要查看表中的内容是否也在 sql 脚本中,如果没有则删除该行。我已经尝试过“diff”和“diffAssoc”方法,但显示所有记录都不同。$diff = $indexes->diffAssoc(get_object_vars(collect($dbIndexes)));

我所做的是,而不是:
$indexes = DB::connection('sqlsrv2')->table('indexes')->get();
谁返回一个对象集合,我用过:
$indexes = DB::connection('sqlsrv2')->select("select * from indexes");
谁返回一个数组。而两者的对比是这样的:
$indexes = array_map('serialize', $indexes);
$dbIndexes = array_map('serialize', $dbIndexes);
$diff = array_merge(array_diff($indexes,$dbIndexes),array_diff($dbIndexes,$indexes));
通过这种方式,它检查两种方式的差异。如果您仅以一种方式进行检查,它将显示差异。
