Notes
- When deleting rows in an internal table, costs are incurred for updating all existing table keys and table indexes. The primary key and all unique secondary keys are updated directly, whereas non-unique secondary keys are only updated if the rows to be deleted are contained within an updated part of a relevant index (lazy update). When deleting a row from a standard table using a secondary key, the primary table index in particular must be updated, and this requires a linear search.
-
There is no implicit selection of a suitable key or index. The used table key or table index is always specified uniquely. The syntax check issues a warning if there is a suitable
secondary table key
but this table key is not used. This warning should be removed through using the key. However, in exceptional cases, it can be bypassed using a
pragma.
