SHOW TRANSACTION
Synopsis
Use the SHOW TRANSACTION statement to show the current transaction isolation level.
Syntax
show_transaction ::= SHOW TRANSACTION ISOLATION LEVEL
show_transaction
Semantics
Supports Serializable, Snapshot and Read Committed Isolation$ using the PostgreSQL isolation level syntax of SERIALIZABLE, REPEATABLE READ and READ COMMITTED respectively. PostgreSQL's READ UNCOMMITTED also maps to Read Committed Isolation.
$ Read Committed Isolation is supported only if the gflag yb_enable_read_committed_isolation is set to true. By default this gflag is false and in this case the Read Committed isolation level of Yugabyte's transactional layer falls back to the stricter Snapshot Isolation (in which case READ COMMITTED and READ UNCOMMITTED of YSQL also in turn use Snapshot Isolation).
TRANSACTION ISOLATION LEVEL
Show the current transaction isolation level.
The TRANSACTION ISOLATION LEVEL returned is either SERIALIZABLE, REPEATABLE READ, READ COMMITTED or READ UNCOMMITTED.
