Oracle and SQL Server(t-sql) syntaxes are very different specially the update statement.

Really? Do you have examples that states your affirmation? I can't see any difference besides the in-built functions that are specific for each SQL language.

<div>
Example-<br />
<br />
This will not work in Oracle but works really well in SQL Server.<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-42364085-1"><span>Update x</span>
<span>SET x.c1 = y.c1</span>
<span>FROM table1 x</span>
<span>INNER JOIN table2 y ON x.a = y.a</span>
</code></pre>
</div>


<div>
Well, that's not ANSI-SQL. In my comment I told that if the author uses ANSI-SQL it won't have issues.<br />
For your example the following will work on both Oracle and SQL Server:<br />

<pre><code class="code-1 nolinks" id="code-20-42364139-1"><span>UPDATE table1</span>
<span>SET c1 = (SELECT y.c1</span>
<span>          FROM table2 y</span>
<span>          WHERE table1.a = y.a);</span>
</code></pre>
<br />
<b>EDIT: Code updated</b>
</div>


<div>
Yes thats what. The one one is so used to SQL Server syntax will face issues like me :)

Thanks for your comments &amp;&nbsp;suggestions. I'll get back.

Hello Folks,<br />
<br />
I need to build a .NET Application. Initially, it will support to Oracle and later with SQL Server.<br />
So, once migrate with Oracle to SQL Server for data and db schema. It will be done by migration tool.<br />
<br />
But, how about CRUD operation, which should common for Oracle and SQL Server?<br />
Should I use plain sql and run time judge with SQL Server &amp;&nbsp;Oracle client OR maintain two entity model?<br />
Do you have any thoughts &amp;&nbsp;suggestions?<br />
<br />

Hello Folks,

But, how about CRUD operation, which should common for Oracle and SQL Server?
Should I use plain sql and run time judge with SQL Server & Oracle client OR maintain two entity model?
Do you have any thoughts & suggestions?

.NET application to support Oracle &amp; SQL Server

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

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

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.
