Detailed Description

Member Enumeration Documentation

enum NdbOperation::AbortOption [inherited]

How should transaction be handled if operation fails.

If AO_IgnoreError, a failure in one operation will not abort the transaction, and NdbTransaction::execute() will return 0 (success). Use NdbOperation::getNdbError() to check for errors from individual operations.

If AbortOnError, a failure in one operation will abort the transaction and cause NdbTransaction::execute() to return -1.

Abort option can be set on execute(), or in the individual operation. Setting AO_IgnoreError or AbortOnError in execute() overrides the settings on individual operations. Setting DefaultAbortOption in execute() (the default) causes individual operation settings to be used.

For READ, default is AO_IgnoreError DML, default is AbortOnError CommittedRead does _only_ support AO_IgnoreError

Enumerator:

DefaultAbortOption	Use default as specified by op-type.
AbortOnError	Abort transaction on failed operation.
AO_IgnoreError	Transaction continues on failed operation.

enum NdbOperation::LockMode [inherited]

Lock when performing read

Enumerator:

LM_Read	Read with shared lock.
LM_Exclusive	Read with exclusive lock.
LM_SimpleRead	Ignore locks, read last committed value. Read with shared lock, but release lock directly

UniqueIndexAccess	Read, update, or delete using unique index.
TableScan	Full table scan.
OrderedIndexScan	Ordered index scan.

int NdbOperation::equal	(	const char *	anAttrName,

	)			`[inherited]`

Define a search condition with equality. The condition is true if the attribute has the given value. To set search conditions on multiple attributes, use several equals (then all of them must be satisfied for the tuple to be selected).

Note:

For insertTuple() it is also allowed to define the search key by using setValue().

There are 10 versions of equal() with slightly different parameters.

If attribute has fixed size, value must include all bytes. In particular a Char must be native-blank padded. If attribute has variable size, value must start with 1 or 2 little-endian length bytes (2 if Long*).

Parameters:

	anAttrName	Attribute name
	aValue	Attribute value.

Returns:: -1 if unsuccessful.

virtual NdbBlob* NdbOperation::getBlobHandle ( const char * anAttrName ) [virtual, inherited]

This method replaces getValue/setValue for blobs. It creates a blob handle NdbBlob. A second call with same argument returns the previously created handle. The handle is linked to the operation and is maintained automatically.

See NdbBlob for details.

For NdbRecord operation, this method can be used to fetch the blob handle for an NdbRecord operation that references the blob, but extra blob columns can not be added with this call (it will return 0).

For reading with NdbRecord, the NdbRecord entry for each blob must reserve space in the row for sizeof(NdbBlob *). The blob handle will be stored there, providing an alternative way of obtaining the blob handle.

	)			`[inherited]`

NdbRecAttr* NdbOperation::getValue	(	const char *	anAttrName,
		char *	aValue = `0`
	)			`[inherited]`

Defines a retrieval operation of an attribute value. The NDB API allocate memory for the NdbRecAttr object that will hold the returned attribute value.

Note:

Note that it is the applications responsibility to allocate enough memory for aValue (if non-NULL). The buffer aValue supplied by the application must be aligned appropriately. The buffer is used directly (avoiding a copy penalty) only if it is aligned on a 4-byte boundary and the attribute size in bytes (i.e. NdbRecAttr::attrSize times NdbRecAttr::arraySize is a multiple of 4).

There are two versions of NdbOperation::getValue with slightly different parameters.

This method does not fetch the attribute value from the database! The NdbRecAttr object returned by this method is not readable/printable before the transaction has been executed with NdbTransaction::execute.

Parameters:

	anAttrName	Attribute name
	aValue	If this is non-NULL, then the attribute value will be returned in this parameter. If NULL, then the attribute value will only be stored in the returned NdbRecAttr object.

Returns:: An NdbRecAttr object to hold the value of the attribute, or a NULL pointer (indicating error).

Define an attribute to set or update in query.

To set a NULL value, use the following construct:

   setValue("ATTR_NAME", (char*)NULL);

There are a number of NdbOperation::setValue methods that take a certain type as input (pass by value rather than passing a pointer). As the interface is currently implemented it is the responsibility of the application programmer to use the correct types.

The NDB API will however check that the application sends a correct length to the interface as given in the length parameter. The passing of char* as the value can contain any type or any type of array. If length is not provided or set to zero, then the API will assume that the pointer is correct and not bother with checking it.

Note:

For insertTuple() the NDB API will automatically detect that it is supposed to use equal() instead.

For insertTuple() it is not necessary to use setValue() on key attributes before other attributes.

There are 14 versions of NdbOperation::setValue with slightly different parameters.

See note under equal() about value format and length.

Parameters:

	anAttrName	Name (or Id) of attribute.
	aValue	Attribute value to set.

Returns:: -1 if unsuccessful.

int NdbOperation::setVarValue	(	const NdbColumnImpl *	,
		const char *	aBareValue,
		const Uint16 &	aLen
	)			`[protected, inherited]`

int NdbIndexOperation::simpleRead ( ) [virtual]

Define the NdbIndexOperation to be a standard operation of type simpleRead. When calling NdbTransaction::execute, this operation reads an existing tuple (using shared read lock), but releases lock immediately after read.

Note:: Using this operation twice in the same transaction may produce different results (e.g. if there is another transaction which updates the value between the simple reads).

Note that simpleRead can read the value from any database node while standard read always read the value on the database node which is primary for the record.

Returns:: 0 if successful otherwise -1.

int NdbIndexOperation::updateTuple ( ) [virtual]

Define the NdbIndexOperation to be a standard operation of type updateTuple.

When calling NdbTransaction::execute, this operation updates a tuple in the table.

Returns:: 0 if successful otherwise -1.

Reimplemented from NdbOperation.

int NdbOperation::write_attr	(	const NdbColumnImpl *	anAttrObject,
		Uint32	RegSource
	)			`[protected, inherited]`

int NdbOperation::write_attrCheck ( const NdbColumnImpl * anAttrObject ) [protected, inherited]

virtual int NdbOperation::writeTuple ( ) [virtual, inherited]

Define the NdbOperation to be a standard operation of type writeTuple. When calling NdbTransaction::execute, this operation writes a tuple to the table. If the tuple exists, it updates it, otherwise an insert takes place.

Returns:: 0 if successful otherwise -1.
