Intermediate Triggers are stored programs, which are automatically executed or fired when some events occur. Triggers are, in fact, written to be executed in response to any of the following events:
– A database manipulation (DML) statement (DELETE, INSERT, or UPDATE).
– A database definition (DDL) statement (CREATE, ALTER, or DROP).
– A database operation (SERVERERROR, LOGON, LOGOFF, STARTUP, or SHUTDOWN).
Triggers could be defined on the table, view, schema, or database with which the event is associated. A trigger is a special kind of a store procedure that executes in response to certain action on the table like insertion, deletion or updation of data. It is a database object which is bound to a table and is executed automatically. You can’t explicitly invoke triggers. The only way to do this is by performing the required action no the table that they are assigned to.
Benefits of Triggers
Triggers can be written for the following purposes:
– Generating some derived column values automatically
– Enforcing referential integrity
– Event logging and storing information on table access
– Auditing
– Synchronous replication of tables
– Imposing security authorizations
– Preventing invalid transactions
This training introduces you to database concepts and the process of building a database from the ground up. The Microsoft SQL Server Training course provides a brief overview of all major components of SQL Server product suite, but focuses on relational DBMS
What is Microsoft SQL?
Each modern business needs to have a way of collecting and analyzing large amounts of data. There are many Relational Database Management Systems (RDBMS) you could choose from, but Microsoft’s SQL Server is the most popular one used by top enterprises as well as small to medium-sized businesses.
Microsoft SQL Server is a relational database management system developed by Microsoft. As a database, it is a software product whose primary function is to store and retrieve data as requested by other software applications, be it those on the same computer or those running on another computer across a network (including the Internet). There are at least a dozen different editions of Microsoft SQL Server aimed at different audiences and for workloads ranging from small single-machine applications to large Internet-facing applications with many concurrent users. Its primary query languages are T-SQL and ANSI SQL.
