- SQL Server Query Elapsed Time. This is based on a forum question and I see many are still confused with SQL Server Query Elapsed Time that you see under Messages tab in SSMS when the session is running with SET STATISTICS TIME ON. SQL Server Elapsed Time represents the total time the query has taken, in milliseconds, to send the output to the console. And this includes Signal Wait Time, time spent on any Wait Types like PageIOLatch_*, IO_Completion or any other wait type including locking/blocking. Let me explain with a ...

Multiple ways to generate metadata / execute Stored Procedures in the SQL adapter For these operations, the adapter reads the System Tables in SQL Server, finds out the parameters to the procedure, and exposes them as IN or INOUT parameters in the WSDL. However, we yet need a way to return the result sets which the Stored Procedure can return at execution time. The adapter exposes these result sets as a return parameter, of type System.Data.DataSet[]. Being an array, multiple result sets can be returned.

- You need the actual execution plan. You can see these from running the SQL query in SQL Management studio with the right button pressed (they'll appear as a tab in the results window). This will show you what parts of the sproc is being run and the time taken up by each bit-just what you want to tune.share | improve this answer.p vote 2 down vote favorite. I would like to measure the time it take to execute a Stored Procedure in SQL Server. But instead of just measuring the entire stored procedure execution I would also like to measure the time each operation inside the stored procedure takes, so I could find bottlenecks.

Measure run time for Oracle SQL Elapsed: 00:00:02.82. For DBA’s, Oracle has several tools for measuring system-wide response time using v$sysmetric, v$active_session_history, v$sqlarea and v$sysmetric_summary. You can also query v$sql for the elapsed_time and executions columns for average SQL response time. Application response time: Within a working application, you can measure response time with the dbms_support package to set trace in the session that your application is running in, and then use tkprof utility to process the resulting trace file.

Query optimization A query is a request for information from a database. It can be as simple as finding the address of a person with SS# 123-45-6789, or more complex like finding the average salary of all the employed married men in California between the ages 30 to 39, that earn less than their wives..ach different way typically requires different processing time. Processing times of the same query may have large variance, from a fraction of a second to hours, depending on the way selected. The purpose of query optimization, which is an automated process, is to find the way to process a given query in minimum time.

PL/SQL (procedural language extension to Structured Query Language) A PL/SQL program that is stored in a database in compiled form and can be called by name is referred to as a stored procedure. A PL/SQL stored procedure that is implicitly started when an INSERT, UPDATE or DELETE statement is issued against an associated table is called a trigger.

Quiescing a D atabase Occasionally you might want to put a database in a state that allows only DBA transactions, queries, fetches, or PL/SQL statements. Such a state is referred to as a quiesced state, in the sense that no ongoing non-DBA transactions, queries, fetches, or PL/SQL statements are running in the system. The quiesced state lets administrators perform actions that cannot safely be done otherwise. These actions include: Actions that fail if concurrent user transactions access the same object--for example, changing the schema of a database table or adding a column to an existing table where a no-wait lock is required.

Timestamps in Cassandra In the above SQL-like table, the timestamp is a SQL-like column. In Cassandra, there is no such thing as SQL-like columns for timestamps. A timestamp in Cassandra is a validity information for the Cassandra (name, value) pair. A Cassandra name can be considered as the equivalent of a SQL-like column. For each row, a corresponding value and timestamp is defined and registered.

- For example, the statistics shown above report that the maximum response time per user transaction has been only .28 second, with the average response time being a blazing .08 second. Oracle certainly wouldn't be to blame in this case.he point is that Oracle Database 10g makes it a lot easier to conduct response-time analysis on SQL statements with simplified data dictionary views, as opposed to the time-consuming trace-and-digest method.
