- Some Inside Out questions:
-
- 1. If one of the SRFind... routines is called using a view comprising two
- connected files with the key set to one of the keys of the parent file, and a
- matching record exists in the parent file but this record “owns” no records in
- the child file, what happens? Does the routine simply fail (kFindFailed),
- clearing the current record of both files? Or does it succeed and clear only
- the current record of the child file and leave the fields belonging to it in
- the view alone?
-
- 2. What use is the connection key? Can I set the current key to this and then
- call an SRFind... routine (using a view consisting only of fields from the one
- file)? What would this do? I can't set the relation ID field so which value
- would be taken?
-
- 3. (Related to question 2.) What happens if I insert a record in a file which
- has a connection and no keys (other than the connection key) through a view
- consisting of fields only from this one file? What value is the relation ID
- field given - zero in all cases, or the record ID of the current record of the
- parent file if there is one? If zero, then presumably, if I don't know
- anything about the contents of the record, I can only retrieve the record again
- if I save its position (SRGetPosition) or record ID (SRGetRecID) somewhere
- immediately after inserting it and then use SRPosition or SRSetRecID
- respectively, right? CAN I LATER ASCRIBE A PARENT TO SUCH A RECORD (i.e. link
- it through its relation ID field to a record in its parent file)? HOW?
-
- 4. Is there a suitable AppleLink bulletin board where I should/could post
- questions regarding Inside Out? (I “cc”ed this to MacApp.Tech$, although
- MacApp has nothing directly to do with Inside Out, especially the above
- questions, because I wanted to reach a wider audience.)
-
- Thanks in advance for your help,
