6 -- Description : Procedures and functions used for sql binding.
7 -- This package gives you a way to manage your bind
8 -- variables by registering them with the package
9 -- and get a indentifier which you can use in
10 -- your dynamic sql, and call the procedure bindvars
11 -- to bind all variables to the cursor passed in.
