28 year old woman dating 24 year old man - Updating a view mssql

Using INSTEAD OF triggers you can override an INSERT, UPDATE, or DELETE operation on a view.For example, you might define an INSTEAD OF INSERT trigger on a view to replace the standard INSERT statement.For other options or clauses in the definition, they are added to the options or clauses of the statement that references the view, but the effect is undefined.

Within a database, base tables and views share the same namespace, so a base table and a view cannot have the same name.

Columns retrieved by the statement can be simple references to table columns, or expressions that use functions, constant values, operators, and so forth.

For example: CREATE TABLE new_materialized_view SELECT * from regular_view; RENAME TABLE materialized_view = old_materialized_view, new_materialized_view = materialized_view; DROP TABLE IF EXISTS old_materialized_view; Creating a materialized view emulation as described above looks good, the only problem is that we are inheriting the lack of indexes My SQL views expose.

My solution is to create a correctly indexed table according to my needs, having the exact same structure as the view, and then running something like this: LOCK TABLES materialized View WRITE; TRUNCATE materialized View; INSERT INTO materialized View SELECT * FROM regular View; UNLOCK TABLES; That way all indexes from materialized View are preserved on every "refresh".

The SQL Server (Transact-SQL) UPDATE statement is used to update existing records in a table in a SQL Server database.

There are 3 syntaxes for the UPDATE statement depending on whether you are performing a traditional update or updating one table with data from another table. If IGNORE is provided, all errors encountered during the update are ignored.If an update on a row would result in a violation of a primary key or unique index, the update on that row is not performed.To create the view explicitly in a given database, use statement are also interpreted with respect to the default database.A view can refer to tables or views in other databases by qualifying the table or view name with the appropriate database name.CREATE TRIGGER TRGI_VW_PAYMENT ON VW_LAST_PAYMENT_DETAILS INSTEAD OF INSERT AS BEGIN INSERT INTO STUDENT_PAYMENT SELECT STD_ID, PAY_AMT, PAY_DATE FROM INSERTED END This Code working fine.
