Variants (Non-exhaustive)
This enum is marked as non-exhaustive
ReadUncommitted
Equivalent to ReadCommitted
.
ReadCommitted
An individual statement in the transaction will see rows committed before it began.
RepeatableRead
All statements in the transaction will see the same view of rows committed before the first query in the transaction.
Serializable
The reads and writes in this transaction must be able to be committed as an atomic “unit” with respect to reads and writes of all other concurrent serializable transactions without interleaving.
