What is the maximum number of columns in a single GaussDB table? How do I query the partition and index information of a partitioned table? What is OID? What is UDF? What wildcards are supported in GaussDB? How do I use them? Is there a limit on the length of a database object na...
What is UDF? What wildcards are supported in GaussDB? How do I use them? Is there a limit on the length of a database object name? How do I view the creation time of a table? How do I create indexes in parallel? How do I create an auto-increment column?
Scalar UDF InliningAutomatically transforms scalar UDFs into relational expressions and embeds them in the calling SQL query. This transformation improves the performance of workloads that take advantage of scalar UDFs. SeeScalar UDF Inlining. Table variable deferred compilationImproves plan quality and over...
Starting with SQL Server 2019 (15.x), batch mode is enabled on eligible analytical workloads whose queries include operations with any type of index (rowstore or columnstore). See Batch mode on rowstore. Scalar UDF Inlining Automatically transforms scalar UDFs into relational expressions and embeds ...
标量UDF 内联 自动将标量 UDF 转换为关系表达式,并将它们嵌入调用 SQL 查询。 此转换提升了利用标量 UDF 的工作负载的性能。 请参阅标量UDF 内联。 表变量延迟编译 提升了引用表变量的查询的计划质量和整体性能。 在优化和初始编译期间,此功能传播基于实际表变量行计数的基数估计。 这种准确的行计数...
