Sql date updating

This is because the insert keyword requires that Expression 2 be a single node.Even though there is only one Salaries node, the singleton is still required.

The project description for project #1 has become outdated.For example, an operation that tries to update the salary amount of two different employees in the following manner will fail: UPDATE HR_XML SET Salaries.modify('replace value of (/Salaries/Marketing/Employee[@ID=("2")]/Salary/text())[1] with ("60000")'), Salaries.modify('replace value of (/Salaries/Marketing/Employee[@ID=("1")]/Salary/text())[1] with ("60000")') GO Instead, multiple updates to the same XML value must be accomplished using entirely separate UPDATE statements. We need to update the salary amount to match that of employee #2 (60600): Notice that we had to perform two separate modify() operations in order to update the salary and tier data.We've looked at examples of the XML DML extension, using the modify() XQuery method.We introduced all three operational keyword sets: insert, replace value of, and delete; and used them to perform some of the more common XML modification operations.We also pointed out some limitations and appropriate workarounds.
