builds the obejct based on real SQL statement
The source statement is also scanned using Qore::SQL::AbstractSQLStatement and column definitions are used to update the source record specification.
| ds | Qore::SQL::AbstractDatasource instance. Note that this object uses a transaction lock for the current thread. |
| sql | a string with SQL statement. Variables binding is provided by sqlargs |
| sqlargs | optional list with sql argumets/variables |
| mapv | a optional hash providing overrides for the default 1:1 input to output field mappings; each hash key is the name in lower case of the output column in the target table; each value is either True (meaning no translations are done; the data is copied 1:1) or a hash describing the mapping; see mapperkeys for detailed documentation for this option |
| opts | an optional hash of options for the mapper; see mapperoptions for a description of valid mapper options plus the following options specific to this object:

returns a list of valid constructor options for this class (can be overridden in subclasses)
