SQL Profiler and SQL Query Analyzer are performance monitoring tools that are included with SQL Server. These tools can be used by a database administrator to diagnose problems and optimize performance. This tutorial introduces only a small portion of the functionality available with SQL Profiler and SQL Query Analyzer. More information on both tools can be found in the HTML Help file, SQL Server Books Online, available from the Microsoft Web site (www.microsoft.com/sql/techinfo/ productdoc/2000/). To learn more about administering SQL Server with ArcSDE, enroll in ArcSDE Administration for SQL Server, a five-day instructor-led course offered by ESRI. Visit the ESRI Web site (www.esri.com) for information about this course and other resources. Data for This Tutorial The data for this tutorial, based on a dataset containing land-use parcels for Wilson County, North Carolina, consists of a personal geodatabase feature class containing parcel data. Download the archived data file, Parcels.zip, from the ArcUser Online Web site. Important: After downloading and unzipping Parcels.zip, open the parcels personal geodatabase. Copy or import the parcels feature class into ArcSDE. If you do not have permission to load data into ArcSDE, get your ArcSDE administrator to copy the data and grant you SELECT privileges for the feature class. Tutorial Overview Before beginning this tutorial, verify that the ArcSDE server is running and that your Working with SQL Profiler HTML Help file, SQL Server Books Online, available from the Microsoft Web site provides, information on SQL Profiler and SQL Querry Analyzer login to SQL Server has appropriate permissions to view the data. In this tutorial you will Ü Create a SQL Profiler trace template Ü Connect to ArcSDE from ArcMap Ü Perform an attribute query Ü View the results of the query in SQL Profiler Ü Copy the traced query to SQL Query Analyzer Ü View query statistics Ü Create a column index in ArcCatalog Ü View query statistics using the new index Step 1: Create a SQL Profiler trace template This step defines a new trace definition in SQL Profiler by specifying which events to trace and what type of information to record for each event. A trace template must be created first to store the trace definition. 1. From the Start menu, choose Programs > Microsoft SQL Server > Profiler to start SQL Profiler. 2.

From the Unselected Data column, add the TextData, Duration, and Reads columns to the Selected data list. 11. Click Save to create the template but do not close SQL Profiler. Step 2: Connect to ArcSDE from ArcMap In this step you will query the Parcels feature class using ArcMap to find Railway right-of-way features. During this step a trace running in SQL Profiler will capture the…….
