getLength() Gets the length of a blob, in bytes getNdbError() Gets an error (an NdbError object) getNdbOperation() Get a pointer to the operation (NdbOperation object) to which this NdbBlob object belonged when created. The operation referenced by ... This section provides information about the NdbBlob class, which models a handle to a blob column and provides read and write access to blob column ...

Do the preceding limitations affect the ability of MySQL to do point-in-time recovery? A.4.28. If replication or binary logging in general (for the purpose of point-in-time recovery) is active, then MySQL DBAs have two security options open to them: ...Where can I find documentation for MySQL stored procedures and stored functions? ...

For geometry values, MySQL distinguishes between the concepts of syntactically well-formed and geometrically valid. Spatial import functions that parse WKT or WKB values raise an error for attempts to create a geometry that is not syntactically ...

When Group Replication's distributed recovery process is carrying out state transfer from the binary log, to synchronize the joining member with the donor up to a specific point in time, the joining member and donor make use of GTIDs (see Section ...However, GTIDs only provide a means to realize which transactions the joining member is ...
