Sql server update statement with where clause

In addition, you can enforce the conditional clause. The condition is defined in the where clause that identifies what rows to modify in the table. The following example updates the columns Bonus with the value , CommissionPct with the value.

SalesPerson table. The following example updates rows in the table Sales. In the following example, we only want to update one row of the Sales. In this case, its BusinessEntityID is equal to And now, we see that the columns Bonus, ComissionPct, and SalesQuota have been changed with new values.

Do I need to do something special for precision on the database? Ourx: The time might be stored with millisecond precision, but the milliseconds might not be displayed.

By filtering out all of the data, you can still create the table without waiting! You now have the CREATE TABLE statement for your new table and you can make some adjustments, like setting the nullability of the columns, changing data types, setting a filegroup, configuring foreign and primary keys and so on.

With this little trick, you can save yourself some time when creating tables. In the previous examples, the created table was always in the same database as the source tables from the SELECT query.

However, it's perfectly possible to have the destination table in another database if you specify a "three-part-name". This is database. Each time we've created a new "persisted" table in a database. But with the INTO clause you can also create temporary tables. These are tables stored in the tempdb database, and they are deleted once the connection is over.

Once the connection drops, the table will be deleted. A local temp table only exists for the connection that created it. Because it might be possible for multiple connections to create temp tables with the same name, a suffix is added to the local temp table in tempdb. A global temp table which has two before its name is a temporary tables that can be shared between multiple connections. Let's create such a global temp table with INTO:.

If you still have the query window open where you created the global temp table, you can create a new query window in SSMS and query the global temp table:. As long as there is at least one connection open that is referencing the global temp table, it will continue to exist. Once every connection is closed, it will be dropped as well.
