concurrent object allocation threads. This improvement changes the way that concurrency is managed with PFS updates so that they can be updated under a shared latch, rather than an exclusive latch. This behavior is on by default in all databases (includingtempdb) starting with SQL Server 2019 (...
A database thus created uses the default MySQL Server database properties (such as those as determined by character_set_database and collation_database) that are in effect on this SQL node at the time the statement is executed. NDB metadata change detection and synchronization. NDB 8.0 ...
which means it is no longer necessary to discover individual tables or to re-trigger synchronization by reconnecting the SQL node to the cluster. In addition, setting this variable tofalseclears the list of objects waiting to be retried.
Access Code - DELETE Statement with DISTINCTROW and T-SQL Access Now() vs. T-SQL GETDATE() ? ADD and SUBTRACT depending on the condition is CASE STATEMENT ADD COLUMN to variable table? Add prefix in data column Add Time in SQL HH:MM:SS to another HH:MM:SS Adding a column to a...
// Scalar subquery is used to return single value as a column. const scalarSub = SQL .uses(tUser) .selectFrom(tArticle) .columns(MAX(tArticle.created)) .where(tUser.createdBy.eq(10)) .asScalar("subColumn"); const joinSub = SQL .uses(tUser) .selectFrom(tArticle) .columns(tArticle...
That is, what is the equivalent of this TSQL query, presuming Table1 has a single row: Select @ScalarVar = Column1 from Table1 to Tim Curwick Tim, You're looking fortoscalar(). For a slightly more advanced example of how to use it (together with makeset() and in()), check out...
One common task that everyone who deploys SQL Server has to account for is making sure that all mission critical SQL Server instances and the databases within them are available whenever the business and end users need them. Availability is a key pillar of the SQL Server platform, and SQL ...
Again: my point is that SQL merged two ideas into one, and mixed their semantics in an inconsistent way, so the meaning ofNULLdepends on the context. I will describe the behaviors ofNULLin different contexts. Comparisons NULL = NULLreturnsNULL. In aprevious articleI explained how to properly...
New features in anorm include:New positional getter on Row. Unified column resolution by label, whatever it is (name or alias). New streaming API; Functions fold and foldWhile to work with result stream (e.g. SQL"Select count(*) as c from Country".fold(0l) { (c, _) => c + 1...
