Rows inserted using INSERT INTO are lost IN SERIALIZABLE mode
Last updated on SEPTEMBER 02, 2017
Applies to:Oracle Database - Enterprise Edition - Version 188.8.131.52 to 184.108.40.206 [Release 8.1.7 to 9.0.1]
Information in this document applies to any platform.
Rows added using INSERT INTO are lost in SERIALIZABLE isolation level .
The problem happens only when using the SERIALIZABLE isolation level; it does not happen when using READ COMMIT isolation level.
- The record is updated just after inserted.
- Commit is not executed between insert and update.
- Primary key is set to the table that does insert/update, and updated record is searched by the primary key condition.
The following behavior is seen:
* Inside a transaction, one session executes the following statement:
INSERT INTO "PROBLEMREPORT" ("ID", "AREA", "DELETED_BY_USER", "TEMPORARY") VALUES (:1, :2, :3, :4)
Here, ":1" is bound to the integer value 587967.
* Later, still inside the same transaction, the same session executes the following statement:
SELECT "ID", "AREA", "DELETED_BY_USER" FROM "PROBLEMREPORT" WHERE "ID" IN (587967) FOR UPDATE
Zero rows are returned by this statement, even though a row with ID 587967 was added previously.
There was no DELETE statement executed on the "PROBLEMREPORT" table by this or any other session.
