Sql date updating
We incorporated the SQL variable '@i' (inside of a sql:variable() extension function), which was used to iterate the Employee nodes.Notice that the salary amount for employee # 4 was not updated, since that employee is in the Accounting department.The ALTER TABLE statement specifies EMPLOYEES as the table to alter.The MODIFY clause permanently modifies the format of the Salary column.We need to remove the description for the time being.
Let's insert a Salary node for employee #4, and populate it with the salary amount from employee #1's Salary node: We've deleted the empty node by indicating its singleton value (2).
The DROP clause permanently drops the Phone column.
Execute the following Microsoft SQL Server T-SQL datetime and date formatting scripts in Management Studio Query Editor to demonstrate the multitude of temporal data formats available in SQL Server.
Attempting to run the query without the singleton will result in an error: We see that the node was placed after the only other existing node residing on the same level (the Marketing node) by default.
Instead, we want the Accounting node to be the first node under the Salaries node.
