How to create XSD schema from MSSQL Database table

 You'll need Microsoft SQL Server Management Studio to run the below query. 

Select the database where you want to run the query against. 

Open a new query window and run the below command 

    DECLARE @SanjeebXsdSchema xml

SET @SanjeebXsdSchema = (SELECT top 1 * FROM [dbo].[BOM_DW_Extract] FOR XML AUTO, ELEMENTS, XMLSCHEMA('sanjeebXsdSchema'))

SELECT @SanjeebXsdSchema

Result:

<xsd:schema xmlns:schema="sanjeebXsdSchema" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:sqltypes="http://schemas.microsoft.com/sqlserver/2004/sqltypes" targetNamespace="sanjeebXsdSchema" elementFormDefault="qualified">
