This section describes the 'unique' identity-constraint, where a combination of certain sub elements or attributes is defined as an identity, which must have unique values. Missing values are acceptable.
A "unique" Identity-Constraint is a constraint on an XML element, where a combination of certain sub elements or attributes is defined as an identity, which must have unique values. Missing values are acceptable. "unique" identity-constraint in XML document is very similar to the concept of ...

If a unique constraint is defined on column COL1 of table TAB1, what are the characteristics of COL1?() A. COL1 will accept NULL values and can be referenced in another table's foreign key specification. B. COL1 will not accept NULL values and cannot be referenced in another tables ...
but it can also occur on user databases when there are many 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 ...

error message is displayed if a user attempts to delete a parent list item with child items that look up to it; or None, which means no delete behavior is enforced (default value). You set a delete behavior through theRelationshipDeleteBehaviorproperty of a lookup field, which is represented...
PCE: a component that can compute constraint-compliant paths based on network topology information. The PCE can be deployed on aroutingdevice or independent server. In most cases, however, it is integrated with a controller. Path computation client (PCC): a client application that requests the ...

However, the presence of a Siegel zero tends to “magnetize” the error term by pulling most of the fluctuations in a particular direction. In many situations, what this means is that one can obtain a refined asymptotic of the form where now fluctuates less than the original , and in par...
