HI Feng,
In any MDO Query Template where you want to 'dynamic' values, map a Param.x template property to each MDO Attribute that you need to insert/update. You can also user Param.x template properties in the Filter and Sort expressions. When you assign or use a Param.x property, enclose it in [] like this:
example attribute mapping:
example Where clause:
where Attribute1 =='[Param6]' //note that you have to quote strings like this.
You can assign a data type to the Params, and assign a default value to a Param. I recommend that you assign a data type to each used Param tha exactly matches the data type of the MDO attribute that you want to map to, or when used in a Sort of Filter expression.
There are no MDO Management tools that I know of, you have to build MDO Queries for all Insert/Update/Delete queries, and manage the MDO object from MII Workbench.
