Examples of java.sql.SQLException$InternalIterator

java.sql.SQLException
An {@code Exception} class that is used in conjunction with JDBC operations.It provides information about problems encountered with database access and other problems related to JDBC
The {@code SQLException} class provides the following information:
- A standard Java exception message, as a {@code String}
- An {@code SQLState} string. This is an error description string whichfollows either the SQL 99 conventions or the X/OPEN {@code SQLstate}conventions. The potential values of the {@code SQLState} string aredescribed in each of the specifications. Which of the conventions is being used by the {@code SQLState} string can be discovered by using the {@code getSQLStateType} method of the {@code DatabaseMetaData} interface.
- An error code, an an integer. The error code is specific to each database vendor and is typically the error code returned by the database itself.
- A chain to a next {@code Exception}, if relevant, which can give access to additional error information.
