TODO: This function is currently not implemented. The procedure here
|
||
|
|
will be along the following lines:
|
||
|
|
|
||
|
|
1. Assert that we have a shared MDL for the given schema, table,
|
||
|
|
tablespace and tablespace files (if relevant). These will all be
|
||
|
|
serialized into the same SDI blob.
|
||
|
|
2. Retrieve the dd::Schema object.
|
||
|
|
3. Retrieve the dd::Table object.
|
||
|
|
[4. Optional: Retrieve the dd::Tablespace object.]
|
||
|
|
[5. Optional: Retrieve the dd::Tablespace_files objects.]
|
||
|
|
6. Create a top level SDI object.
|
||
|
|
7. Fill inn top level object details, e.g. dictionary version etc.
|
||
|
|
8. Fore each relevant object retrieved, serialize the object,
|
||
|
|
including preparation of references to loosely coupled objects,
|
||
|
|
e.g. collations.
|
||
|
|
9. For each serialized object, add it to the top level object as an
|
||
|
|
array element.
|
||
|
|
10. Generate a string representation of the serialized meta data.
|
||
|
|
11. Assign output parameters and return.
