<div class="textblock"><p>A std::string work-alike that can convert itself from SQL text data formats to C++ data types. </p>
<p>This class is an intermediate form for a SQL field, normally converted to a more useful native C++ type, not used directly. The only exception is in dealing with BLOB data, which stays in <a class="el" href="classmysqlpp_1_1String.html" title="A std::string work-alike that can convert itself from SQL text data formats to C++ data types.">String</a> form for efficiency and to avoid corrupting the data with facile conversions. Even then, it's best to use it through the typedef aliases like sql_blob in <a class="el" href="sql__types_8h.html" title="Declares the closest C++ equivalent of each MySQL column type.">sql_types.h</a>, in case we later change this underlying representation.</p>
<p><a class="el" href="classmysqlpp_1_1String.html" title="A std::string work-alike that can convert itself from SQL text data formats to C++ data types.">String</a>'s implicit conversion operators let you can use these objects naturally:</p>
<div class="fragment"><div class="line"><a class="code" href="classmysqlpp_1_1String.html#ae711df130eb705131bb4121b58114304">String</a>(<span class="stringliteral">"12.86"</span>) + 2.0 </div></div><!-- fragment --><p>That will give you 14.86 (approximately) as you expect, but be careful not to get tripped up by C++'s type conversion rules. If you had said this instead:</p>
<div class="fragment"><div class="line"><a class="code" href="classmysqlpp_1_1String.html#ae711df130eb705131bb4121b58114304">String</a>(<span class="stringliteral">"12.86"</span>) + 2 </div></div><!-- fragment --><p>the result would be 14 because 2 is an integer, and C++'s type conversion rules put the <a class="el" href="classmysqlpp_1_1String.html" title="A std::string work-alike that can convert itself from SQL text data formats to C++ data types.">String</a> object in an integer context.</p>
<p>You can disable the operator overloads that allow these things by defining MYSQLPP_NO_BINARY_OPERS.</p>
<p>This class also has some basic information about the type of data stored in it, to allow it to do the conversions more intelligently than a trivial implementation would allow. </p>

But, if you're using UTF-8 in the database, you will need to "widen" the UTF-8 data to use a fixed-size character set like UCS-2 and count the characters that way. You might use std::wstring, for example. </p>
