Summary0004840: Sybase ASE primary key update should create update event when only one record is updated
DescriptionWhen Sybase ASE primary key update occurs, we capture a delete event and an insert event.

This breaks when there are foreign key constraints that refer to this table, referring to non-primary key columns.
This case is rare.
It breaks because we execute a delete on the target, which will cause the foreign key constraint to fail.

The functionality of a primary key update on Sybase ASE should change such that if only one record is updated when a primary key update occurs, then create an update event, joining the "insert" result set and the "delete" result set with a "ON 1=1". This will link the delete record with the insert record inside the trigger together, successfully linking the two records together.
Steps To Reproduce1. Create table with a primary key and another column.
2. Create a unique index on the other column (required in order to refer to this column with a foreign key constraint).
3. Create another table that has a column that refers to the other column on table 1 with a foreign key constraint.
4. Insert a record into table 1.
5. Insert a record into table 2 with a value in the column referring to the record in table 1.
6. Update the primary key value in table 1.

The delete on the target should fail.
