Isolation level for the connection

You can specify the isolation level either as a character string or as an integer (depending how you have declared it in the java.sql.Connection class).

You can enter the following character strings:

You can enter the following integer values: see Concepts of the Database System, Isolation Level.

Be sure to observe the use of upper and lower case, see Concepts of the Database System, Conventions for User Names and Passwords.
