SQL Server Random Prefetching Example Now we will try to understand random prefetching with some examples. For this we need to build another table with some random data. Random prefetching can be experienced with a nested loop join, thus I will force the optimizer to choose a nested loop join...
The query extracts the name of the bucket and the account ID to which the bucket belongs from the resources object. SELECT awsregion, replace(unnested.resources_entry.ARN,'arn:aws:s3:::') as deleted_bucket, eventtime AS time_deleted, useridentity.username, unnested.resources_entry.accountid...
ADO.NET does not define a query language; therefore, data providers are not required to mask the differences in supported SQL statements between databases. DataDirect Technologies™ provides support for ODBC/JDBC SQL escapes for scalar functions, outer joins, and stored procedures in our providers....
