创建Relation并Add到数据库

比如说，创建一个AssmStrc(Bom关系)的Relation,设置一些属性，然后添加到数据库去：

ObjectPtr assmObj = NULL;

ObjectPtr assmMstrObj = NULL;

ObjectPtr asmstrcRel = NULL;

string dbName = NULL;

 

//...

dstat = ConstructRelation(AssmStrcClass, assmObj, assmMstrObj, mfail, &asmstrcRel);

 

objSetAttribute(asmstrcRel, AttribueName, AttributeValue);

//...

dstat = BeginDbFrame(AssmStrcClass, &dbName, mfail);

dstat = InsertDbRelation(newRelObj, assmObj, assmMstrObj, mfail);

dstat = EndDbFrame(AssmStrcClass, dbName, mfail);

//...
