jdk.sql.BatchUpdateException — clojure-interop/java.sql 1.0.5

The subclass of SQLException thrown when an error occurs during a batch update operation. In addition to the information provided by SQLException, a BatchUpdateException provides the update counts for all commands that were executed successfully during the batch update, that is, all commands that were executed before the error occurred. The order of elements in an array of update counts corresponds to the order in which commands were added to the batch.

After a command in a batch update fails to execute properly and a BatchUpdateException is thrown, the driver may or may not continue to process the remaining commands in the batch. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will have an element for every command in the batch rather than only elements for the commands that executed successfully before the error. In the case where the driver continues processing commands, the array element for any command that failed is Statement.EXECUTE_FAILED.

A JDBC driver implementation should use the constructor BatchUpdateException(String reason, String SQLState, int vendorCode, long []updateCounts,Throwable cause) instead of constructors that take int[] for the update counts to avoid the possibility of overflow.

If Statement.executeLargeBatch method is invoked it is recommended that getLargeUpdateCounts be called instead of getUpdateCounts in order to avoid a possible overflow of the integer update count.

Constructor.

Constructs a BatchUpdateException object initialized with a given reason, SQLState, vendorCode cause and updateCounts.

reason - a description of the error - java.lang.String sql-state - an XOPEN or SQL:2003 code identifying the exception - java.lang.String vendor-code - an exception code used by a particular database vendor - int update-counts - an array of int, with each elementindicating the update count, Statement.SUCCESS_NO_INFO or Statement.EXECUTE_FAILED for each SQL command in the batch for JDBC drivers that continue processing after a command failure; an update count or Statement.SUCCESS_NO_INFO for each SQL command in the batch prior to the failure for JDBC drivers that stop processing after a command failure Note: There is no validation of updateCounts for overflow and because of this it is recommended that you use the constructor BatchUpdateException(String reason, String SQLState, int vendorCode, long []updateCounts,Throwable cause) . - int[] cause - the underlying reason for this SQLException (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown. - java.lang.Throwable

get-large-update-counts clj

(get-large-update-counts this)

Retrieves the update count for each update statement in the batch update that executed successfully before this exception occurred. A driver that implements batch updates may or may not continue to process the remaining commands in a batch when one of the commands fails to execute properly. If the driver continues processing commands, the array returned by this method will have as many elements as there are commands in the batch; otherwise, it will contain an update count for each command that executed successfully before the BatchUpdateException was thrown.

This method should be used when Statement.executeLargeBatch is invoked and the returned update count may exceed Integer.MAX_VALUE.

returns: an array of long containing the update counts for the updates that were executed successfully before this error occurred. Or, if the driver continues to process commands after an error, one of the following for every command in the batch:

an update count Statement.SUCCESS_NO_INFO to indicate that the command executed successfully but the number of rows affected is unknown Statement.EXECUTE_FAILED to indicate that the command failed to execute successfully - long[]

get-update-counts clj

(get-update-counts this)

Retrieves the update count for each update statement in the batch update that executed successfully before this exception occurred. A driver that implements batch updates may or may not continue to process the remaining commands in a batch when one of the commands fails to execute properly. If the driver continues processing commands, the array returned by this method will have as many elements as there are commands in the batch; otherwise, it will contain an update count for each command that executed successfully before the BatchUpdateException was thrown.

The possible return values for this method were modified for the Java 2 SDK, Standard Edition, version 1.3. This was done to accommodate the new option of continuing to process commands in a batch update after a BatchUpdateException object has been thrown.

returns: an array of int containing the update counts for the updates that were executed successfully before this error occurred. Or, if the driver continues to process commands after an error, one of the following for every command in the batch:

an update count Statement.SUCCESS_NO_INFO to indicate that the command executed successfully but the number of rows affected is unknown Statement.EXECUTE_FAILED to indicate that the command failed to execute successfully - int[]
