When building MySQL++ with SunStudio 12.2 compiler on both Solaris 10 for Sparc and Solaris 11 Express for Sparc with the following message:

/home/ahulsbos/scratch/src/mysqlpp/bk-deps CC -c -o mysqlpp_connection.o -I. -KPIC -DPIC -I/opt/pd/mysql5/include -g ./lib/connection.cpp
"./lib/null.h", line 174: Error: In this declaration "data" is of an incomplete type "mysqlpp::String".
"./lib/qparms.h", line 102: Where: While specializing "mysqlpp::Null<mysqlpp::String, mysqlpp::NullIsNull>".
"./lib/qparms.h", line 102: Where: Specialized in non-template code.
1 Error(s) detected.

The issue can be fixed by moving the definition of 'SQLTypeAdapter& SQLQueryParms::operator [](size_type n)' from the header file 'qparms.h' to 'qparms.cpp' file. The following patches implement the fix:
