The following rules apply to using DELETE.
- All correlation names must be specified in the FROM clause.
- The activity count in the success response for a DELETE statement reflects the total number of rows deleted.
- A DELETE statement that references objects in multiple databases should use fully-qualified names. Name resolution problems may occur if referenced databases contain tables or views with identical names and these objects are not fully qualified. Name resolution problems can occur even if the identically named objects are not explicitly referenced.
- You cannot delete a row from a base table that causes an insert into a join index that has row partitioning such that a partitioning expression for that index row does not result in a value between 1 and the number of partitions defined for that level. Otherwise, Teradata Database aborts the request (ANSI mode) or the transaction (Teradata mode).
- You cannot delete a row from a base table that causes an update of an index row in a join index with row partitioning such that a partitioning expression for that index row after the update does not result in a value between 1 and the number of partitions defined for that level. Otherwise, Teradata Database aborts the request (ANSI mode) or the transaction (Teradata mode).
