READ_ISOLATION_LEVEL= DBMS-specific value

Syntax Description

See the reference documentation for your DBMS for additional details.

Details

The degree of isolation defines the following degrees:
  • the degree to which rows that are read and updated by the current application are available to other concurrently executing applications
  • the degree to which update activity of other concurrently executing application processes can affect the current application.
The ODBC and DB2 drivers ignore this option if READ_LOCK_TYPE= is not set to ROW.
