![]() The duration (in microseconds) of the event. The name of the database in which the user statement is running. Determine the value for a database by using the DB_ID function. SQL Server Profiler displays the name of the database if the ServerName data column is captured in the trace and the server is available. The ID of the database specified by the USE database_name statement, or the ID of the default database if no USE database_namestatement has been issued for a given instance. The amount of CPU time (in milliseconds) that is used by the event. You can parse the statement text to determine which permissions were applied to which columns. Indicates whether a column permission was set. This data column is populated if the client process ID is provided by the client. The ID assigned by the host computer to the process where the client application is running. The binary value dependent on the event class that is captured in the trace. Value ( bigint data type), which depends on the event class specified in the trace. This column is populated with the values passed by the application and not the name of the program. The name of the client application that created the connection to an instance of SQL Server. The following table describes the SQL Server Profiler data columns, which are the same data columns as those used by SQL Trace, and indicates the columns that are selected by default. SQL Trace uses data columns in the trace output to describe events that are returned when the trace runs. Use Data Columns to Describe Returned Events In SQL Server Profiler, a table that is created when a trace is saved to a table. In SQL Server Profiler, a file that defines the event classes and data columns to be collected in a trace. ![]() To collect and monitor events in an instance of SQL Server.Ī collection of event classes, data columns and filters that identify the types of events to be collected during a trace.Ĭriteria that limit the events that are collected in a trace. The event class contains all of the data columns that can be reported by an event.Ī collection of events and data returned by the Database Engine. The occurrence of an action within an instance of the Microsoft SQL Server Database Engine.Ī type of event that can be traced. The following terms describe the key concepts of SQL Trace. The following diagram shows how SQL Trace gathers events during a tracing. From the queue, the trace information is either written to a file or can be used by SMO in applications, such as SQL Server Profiler. ![]() If filters have been defined for the event class in the trace definition, the filters are applied and the trace event information is passed to a queue. After an event occurs, if the event class has been included in a trace definition, the event information is gathered by the trace. For more information about events, see SQL Server Event Class Reference. SQL Trace ArchitectureĮvent Sources can be any source that produces the trace event, such as Transact-SQL batches or SQL Server events, such as deadlocks. This allows you to write custom applications specific to the needs of your enterprise. These system stored procedures can be used from within your own applications to create traces manually, instead of using SQL Server Profiler. Microsoft SQL Server provides Transact-SQL system stored procedures to create traces on an instance of the SQL Server Database Engine. For more information on Extended Events, see Quick Start: Extended events in SQL Server and SSMS XEvent Profiler. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. This feature will be removed in a future version of Microsoft SQL Server. The namespace that contains the Microsoft SQL Server Trace and Replay objects are also deprecated. SQL Trace and SQL Server Profiler are deprecated.
