Does it possible use read only committed in Teradata?

I have found that Teradata uses:

READ_ISOLATION_LEVEL= ACCESS|READ|WRITE

How it correspond to usual read commited/dirty in usual databases? Thanks.

Solution

  • Not sure if this addresses your question entirely:

    ACCESS locking would allow dirty reads allows WRITE lock to be in place. READ locking allows only committed reads and can block WRITE/EXCLUSIVE locks while reading data. WRITE lock prevents READ locks from access data but allows ACCESS (dirty read) lock to access data.
