To apply SQL Server for XML generation XML to avoid spelling strings in C #

Recently, when review code, there was a function of querying a column in the database and then generating a

<rootelements>
<col>a</col>
<col>b</col>
<col>c</col>
</rootelements>

The developer does this by returning a result set and then using the loop method to spell the string. Then parse to XML

In fact, SQL Server support for XML has been greatly enhanced since 05. We can use the following line of SQL to return the results above

Select col from table for XML XPath ('), Root (' rottelements ')

XPath (') indicates that each row no longer generates an XML root element. If written

Select col from table for XML XPath (), Root (' rottelements ')

<rootelements>
<row>
<col>a</col>row
</row>
<row>
<col>b</col>row
</row>
<row>
<col>c</col>row
</row>
</rootelements>
