Complex data object returned from oracle

Hi there,

It is my first time posting question here, and if anything not clear please let me know. I am having trouble with complex object returned from stored procedure. I have something like this:


Then I do this is java:

My issue is when array.getArray() (Point A) is called, then it calls A.readSQL() (Point B) first so that all data is set and saved somewhere. Then at Point C, it calls A.readSQL() again but at this time there no more data to read as it has been read, and the result is I get B object with null values, no exception occurs. I been struggling for 2 days and couldn't figure it out. Everything parses out correctly if I use B as param instead of BLIST.

Please help. Thanks.

Carl,
I suggest using Oracle's JDBC thin driver which maps database table types, like your BLIST type, to java.sql.Array and object types, like your types A and B, to java.sql.Struct.
Also, I personally prefer using a PL/SQL stored function, rather than a stored procedure with an OUT parameter.

Good Luck,
Avi.
