Your brother have a oracle to debug the question for you, when I was in the adjustment of the oracle stored procedure code will encounter type custom data types of data types, but sometimes I want to see directly inside the data type of value, is there any way to see? Such as a. col1 I want to know his worth, I know now that one way is to put it to a variable, such as v_a=a.c ol1 so I monitor v_a can know the value, but because of our process were written a long time ago, when they are writing at the time of judgment processing is directly with a.c ol1 this form directly to judgment, not to copy a variables through the first judgement, I tried directly in toad monitoring a.c ol1 found not its value, do you have any brother, give a way to directly see the value, and I don't know if my monitor value when the custom data types to write the wrong grammar,
