Struct TransactionInProgress

pub struct TransactionInProgress;

A type parameter for Connection::oci_attr to get OCI_ATTR_TRANSACTION_IN_PROGRESS as bool, which indicates whether the connection has a currently active transaction.

Note that this requires Oracle client 12.1 or later.

Examples

use oracle::oci_attr::TransactionInProgress;

// no active transaction at first
assert_eq!(conn.oci_attr::<TransactionInProgress>()?, false);

// start a transaction
conn.execute("insert into TestTempTable values (1, 'val1')", &[])?;
assert_eq!(conn.oci_attr::<TransactionInProgress>()?, true);

// rollback the transction
conn.rollback()?;
assert_eq!(conn.oci_attr::<TransactionInProgress>()?, false);
