Therefore, you can control which user account SQL Server uses to validate permissions on any database objects referenced by the function. EXECUTE AS can't be specified for inline table-valued functions. For more information, see EXECUTE AS Clause (Transact-SQL). INLINE = { ON | OFF } ...
Chapter 5 Table Expressions 一个表表达式(table expression)是一个命名的查询表达式,代表一个有效的关系表。SQL Server包括4种表表达式:派生表(derived tables)、公用表表达式(common table expressions (CTEs),)、视图(views)、内联表值函数(inline table-valued functions (inline TVFs))。使用表表达式的好处通常在...

SQL SERVER中的用户定义函数(User Defined Functions 简称UDF)分为标量函数(Scalar-Valued Function)和表值函数(Table-Valued Function)。其中表值函数又分为Inline table-valued functions和Multistatement table-valued functions。 用户定义函数(UDF)在 SQL Server 中发挥重要的作用。用户定义函数可以用于执行复杂的逻辑,...

其中Collection<String>参数在几种分片策略中使用一致,在分库时值为所有分片库的集合databaseNames,分表时为对应分片库中所有分片表的集合tablesNames;PreciseShardingValue为分片属性,其中logicTableName为逻辑表,columnName分片健(字段),value为从 SQL 中解析出的分片健的值。
For all installations of SQL Server, the default compatibility level is associated with the version of the Database Engine, as seen in this table. For new development work, always plan to certify applications on the latest database compatibility level. New Transact-SQL syntax isn't gated by da...
ALTER TABLE modifies a table definition by altering, adding, or dropping columns and constraints. ALTER TABLE also reassigns and rebuilds partitions, or disables and enables constraints and triggers.
PolyBase: RLS is supported with external tables in Azure Synapse and SQL Server 2019 CU7 or higher versions. Memory-Optimized Tables: The inline table-valued function used as a security predicate on a memory-optimized table must be defined using the WITH NATIVE_COMPILATION option. With this opti...
