This section discusses the
structure, which contains status and other information about
errors, including error codes, classifications, and messages.
NdbError consists of six parts, listed here,
of which one is deprecated as of MySQL Cluster NDB 6.2.19, MySQL
Cluster NDB 6.3.29, and MySQL Cluster NDB 7.0.10:
The error status is described by a value of the
Status type. See
Section 184.108.40.206.2, “The
NdbError::Status Type”, for possible
Status values and how they should be
The error classification is described by a value of the
Classification type. See
Section 220.127.116.11.1, “The
NdbError::Classification Type”, for possible
classifications and their interpretation. Additional information
is provided in Section 7.2.3, “NDB Error Classifications”.
It is not recommended to write application programs which are dependent on specific error codes. Instead, applications should check error status and classification. More information about errors can also be obtained by checking error messages and (when available) error detail messages. However—like error codes—these error messages and error detail messages are subject to change.
A listing of current error codes, broken down by classification,
is provided in Section 7.2.2, “NDB Error Codes and Messages”. This listing
is updated with new MySQL Cluster releases. You can also check
in the MySQL Cluster sources.
MySQL Error code: This is the corresponding MySQL Server error code. MySQL error codes are not discussed in this document; please see Server Error Codes and Messages, in the MySQL Manual, for information about these.
Error details: This can often provide additional information (not found in the error message) about an error, specific to the circumstances under which the error is encountered. However, it is not available in all cases.
Where not specified, the error detail message is
