sql server management studio tutorial 2016 create table

This can be a number, string, date and Boolean etc. The data type defines the type of the data that the column is going to hold. It is also necessary to assign data type to each column. Again avoid using the reserved keywords, else you need to follow the delimited identifiers rules when referring the columns in Query. The column name must be UNIQUE within the table. We must also give a name to each column, which also must follow the naming rules for the identifiers. If you use them then you must always enclose the table in square brackets as delimited identifiers. Also note that you should avoid using the reserved keywords. The name must follow the naming rules for the identifiers. The table name must be unique under a schema. We can create more schema using the create schema query. To create a SQL table using XML elements, all you have to do is to change the mode value of the OPENXML function to 2 and change the name of the attributes to the name of the element you want to retrieve.Note that, whenever we create the database, the SQL Server automatically creates the default schema dbo. In the output you will see values from the Name and Make attributes of the CarInfo element as shown below: In our case the CarInfo element has two attributes Name, and Make, therefore we retrieve both.Īs a final step, we execute the sp_xml_removedocument stored procedure to remove the XML document from the memory. Next, inside the WITH clause, we need to define the name and type of the attributes that you want returned. The mode value of 1 returns the attributes only. The OPENXML function takes three parameters: the handle to the XML document, the path of the node for which we want to retrieve the attributes or elements and the mode. Next, we use the OPENXML function to read the contents of the XML document. It takes the handle and the document variable as parameters and creates an association between them. The sp_xml_preparedocument performs this task. To read the attributes and elements of the XML document, we need to attach the handle with the XML document.

Next, we create a handle for the XML document. At this point in time, the XML document is loaded into the memory. Next using the SELECT statement we print the contents of the XML file. In the script above we declare an XML type variable The variable stores the result returned by the OPENROWSET function which retrieves XML data in binary format.
