TDS packets, network volumes transferred etc. The Client Statistics kinda give an insight on what is going on beyond the SQL Server internals, i.e. I like using Client statistics when developing complex logic queries and procedures in SQL Server. It’s another useful tool in the SSMS toolbox! It does, however, give you access to information that you might otherwise need to keep track of in your head, or scribbled on a Post-It Note – like I used to do when writing report queries.
Figure 2 – Client Statistics for multiple executions of a queryĬlient Statistics is not as in-depth of a tool as, say, execution plans, showing you where the performance of your query can be improved. You’ll even see green arrows for improved performance, and red arrows for worse performance. You can, at a glance, compare the changes. Thus, as you are making changes to a query – perhaps changing the conditions in the WHERE clause, or comparing an AVERAGE to a window function – the statistics will update. Statistics will be shown for the ten most recent executions, and they will be averaged, as shown in Figure 2. That’s useful when you run a query once, but its usefulness becomes more apparent when you are tuning a query. The time statistics tells you how much time was spent processing on the client versus how much time was spent waiting for the server. The network statistics lets you see how much traffic is moving from your client to the server and back. You can see the number of rows affected or returned, and the number of transactions executed.
Some really valuable information can be found here, such as the number of INSERT, DELETE, UPDATE, and SELECT statements – think of how useful that can be when tuning a complex stored procedure. Open a query editor window, click on it to highlight it, write a query, and execute it. This button is located on the SQL Editor toolbar. I mentioned it in last week’s webcast, “ SSMS: More Than Meets The Eye“, but I wanted to give you more detail about it here. Select Reset Client Statistics from the Query menu to reset the average.” Statistics from successive query executions are listed along with the average values. When Include Client Statistics is selected from the Query menu, a Client Statistics window is displayed upon query execution. MSDN says it “Displays information about the query execution grouped into categories. At SQL Saturday #118 Wisconsin earlier this year, I was watching a presentation and the presenter clicked “Include Client Statistics”. However, SQL Server Management Studio (SSMS) has so many I haven’t gotten through all of them. I like clicking all the buttons in applications I work with.
#Sql server client manual#
I have to read the user manual of everything I buy so I know all of its features. Content Source: docs/relational-databases/native-client/applications/support-policies-for-sql-server-native-client.I’m curious.
Could you please clarify whether Native Client 11.0 supports connection to SQL Server 2019. “SQL Server Native Client 11.0 supports connections to, SQL Server 2008, SQL Server 2008 R2, SQL Server 2012 (11.x), SQL Server 2014 (12.x), and Azure SQL Databases" Ĭonnection to SQL Server 2019 using Native Client 11.0 works in some environments and fails in another. From the below document it looks like SQL Native Client 11.0 does not support connection to SQL Server 2016 and above.
