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)));
