Top SQLs

This collection collects data of SQL Statements that consumed the highest amount of resources during the specified time range.

SQL Server.

Real-time

60

Online

300

Offline

900

Creation Date

Indicates the date the SQL statement was first run, thereby allowing the creation of SQL statement statistics

Diff. From Executions

Indicates the incremental difference in the number of SQL executions since the last sample.

Diff. From Total CLR Time

Indicates the incremental difference, since the last sample, in the total CLR time spent for executing the SQL statements.

Diff. From Total CPU

Indicates the incremental difference, since the last sample, in the total CPU time consumed by the SQL executions.

Diff. From Total Elapsed Time

Indicates the incremental difference, since the last sample, in the total time consumed for carrying out the SQL statement.

Diff. From Total I/O

The incremental difference, since the last sample, in the total number of I/O operations that were carried out for executing the SQL statements.

Diff. From Total Logical Reads

The incremental difference, since the last sample, in the total number of logical reads carried out for executing the SQL statements.

Diff. From Total Physical Reads

The incremental difference, since the last sample, in the total number of physical reads carried out upon executing SQL statements.

Diff. From Total Wait Time

The incremental difference, since the last sample, in the total wait time consumed upon executing SQL statements.

Executions

Indicates the number of times the SQL script executed for a unique SQL Handle.

Last Executed

Indicates the last time the SQL statement was executed (last run).

Plan Handle

Provides a unique identification of a SQL statement execution plan.

Query Hash

Query hash value indicates the logic behind a SQL script. Similar SQL queries (that is, SQL queries that differ by literal rather than logical values) have the same query hash value. Therefore, if the execution of such queries results in different query plan hash values, the reason for the difference is most probably the data against which the queries were executed.

SQL Handle

Provides a unique identification of a SQL batch script.

SQL Hit Rate

The percentage of SQL Statements that found the required plan already in the cache.

If a matching plan is found, SQL Server does not need to compile the query or the stored procedure. This can save a significant amount of CPU resources, and speed up SQL Server queries.

 

Statement End Offset

A SQL batch may be combined of multiple SQL statements. While the SQL handle identifies the batch as a whole, this metric provides a unique identification of a specific SQL statement, by indicating the end position of the statement within the SQL batch.

Statement Start Offset

A SQL batch may be combined of multiple SQL statements. While the SQL handle identifies the batch as a whole, this metric provides a unique identification of a specific SQL statement, by indicating the start position of the statement within the SQL batch.

Total CLR Time

The total CLR time spent for executing the SQL statements.

Total CLR Time Per Exec

 

The average CLR time spent for executing a single CLR execution.

Total CLR Time Rate Top SQL

The total CLR time per second spent for executing the CLR execution.

Total CPU

The total CPU time consumed by the SQL executions.

Total CPU Per Exec

The average CPU time spent for executing a single SQL statement.

Total Elapsed Time

The total time consumed for carrying out the SQL statement executions.

Total Elapsed Time Per Exec

The average time spent for executing a single SQL statement.

Total I/O

The total number of I/O operations that were carried out for executing the SQL statements.

Total I/O per Exec

The average number of I/O operations carried out for executing a single SQL statement.

Total I/O Rate Top SQL

The total number of I/O operations per second that were carried out for executing the SQL statements.

Total Logical Reads

The total number of logical reads carried out for executing the SQL statements.

Total Logical Reads Per Exec

The average number of logical reads carried out for executing a single SQL statements.

Total Logical Reads Rate Top SQL

The total number of logical reads per second that were carried out for executing the SQL statements.

Total Physical Reads

The total number of physical reads carried out for executing the SQL statements.

Total Physical Reads Per Exec

The average number of physical reads carried out per execution of a single SQL statement.

Total Wait Time

The total wait time spent while executing the SQL statements.

Total Wait Time Per Exec

The average time spent on wait events while executing a single SQL statement.

SQL Batch

The full text of the SQL execution batch.

Top SQL Long Text

This collection retrieves the full SQL text script of a given SQL handle.

This collection is an on-demand collection, which has no pre-defined sampling intervals.

Query Text

The full text of the SQL statement.

Top SQL Plan

This collection retrieves a query plan of a given SQL handle.

SQL Server.

This collection is an on-demand collection, which has no pre-defined sampling intervals.

IMPORTANT:  

Query Plan

The full query plan of the SQL statement.
