In what context or scenario you are checking? Are you inserting data?
</div>


<div>
WITH (TABLOCK)<br />
Basically when we move data from one table to another it is recommended to use TABLOCK hint on the destination table. This will reduce concurrency because it will immediately take the table lock on the destination table. So this hint will help you in inserting data quickly.<br />
<br />
Example<br />

<pre><code class="code-1 nolinks" id="code-20-42385584-1"><span>INSERT INTO DestinationTable WITH (TABLOCK) (&lt;Column1, Column2.....&gt;)</span>
<span>SELECT Column1, Column2... FROM Yourtable</span>
</code></pre>
<br />
If you are loading data then I recommend you to also read the Performance &nbsp;guide for data loading. &lt;<a href="https://msdn.microsoft.com/en-us/library/dd425070.aspx" rel="ugc">https://msdn.microsoft.com/en-us/library/dd425070.aspx</a>&gt;<br />
<br />
WITH(NOLOCK)<br />
It is equal to using READ UNCOMMITED as a transaction isolation level. So, you stand the risk of reading an uncommitted row that is subsequently rolled back, i.e. data that never made it into the database. So, while it can prevent reads being deadlocked by other operations, it comes with a risk. Basically you can get dirty reads. WITH(NOLOCK) - Does not improve performance. WITH(NOLOCK) is NOT by default.<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-42385584-2"><span>SELECT Column1, Column2... FROM Yourtable WITH (NOLOCK)</span>
</code></pre>
So if you are loading data first option WITH (TABLOCK) is good.

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality. Component services include integration (SSIS), reporting (SSRS), analysis (SSAS), data quality, master data, T-SQL and performance tuning.

Microsoft SQL Server

SQL (Structured Query Language) is designed to be used in conjunction with relational database products as of a means of working with sets of data. SQL consists of data definition, data manipulation, and procedural elements. Its scope includes data insert, query, update and delete, schema creation and modification, and data access control.
