The internal pseudo-type is used to declare functions that are meant only to be called internally by the database system, and not by direct invocation in an SQL query. If a function has at least one internal-type argument then it cannot be called from SQL. You are advised not to create...
Sample Implementation using User-Defined Function: Let's demonstrate the pseudo-Resource Governor concept with a sample implementation using a user-defined function. In this example, we'll create a function named `dbo.GetMaxDopByUsername`, which fetches the Maximum Degree of...

and not by direct invocation in an SQL query. If a function has at least one internal-type argument then it cannot be called from SQL. To preserve the type safety of this restriction it is important to follow this coding rule: do not create any function that is declared to returninternal...
A: It's essentially aformat-preserving encryptionscheme. In an inner loop, there's a balanced 9-roundFeistel Cipher, with a block size determined by the range of the sequence. The round function hashes the current block with bits from the key. A cycle-walking outer loop iterates over tha...
There's an interesting little niggle in the Kafka Producer setup which is not immediately obvious and required a bit of digging in StackOverflow as well as enabling debug output with librdkafka: def _get_kafka_configuration(): """ Common function to retrieve the Kafka configuration. """ ...
