addScalar in class SqlMetaType

Parameters:

query - the SQL Engine query, an adapter or proxy to the internal JDBC or ORM staff

dbName - the name of a database query output, it can be the column name or the alias name

attributeType - the Java type of of the attribute in the result class

setResult

public void setResult(SqlRuntimeContext runtimeCtx,
                      Object resultInstance,
                      String attributeName,
