JET_RECSIZE Structure
Applies to: Windows | Windows Server
JET_RECSIZE Structure
The JET_RECSIZE structure is used by JetGetRecordSize to return information about a record's usage requirements in user data space, number of set columns, number of values, and ESE record structure overhead space.
Windows Vista: The JET_RECSIZE structure is introduced in Windows Vista.
typedef struct {
unsigned __int64 cbData;
unsigned __int64 cbLongValueData;
unsigned __int64 cbOverhead;
unsigned __int64 cbLongValueOverhead;
unsigned __int64 cNonTaggedColumns;
unsigned __int64 cTaggedColumns;
unsigned __int64 cLongValues;
unsigned __int64 cMultiValues;
} JET_RECSIZE;
Members
cbData
User data set in the record.
Note The key size is not included in this.
cbLongValueData
User data associated with the record but stored in the long-value tree.
Note This does not count intrinsic long-values.
cbOverhead
The overhead of the ESE record structure for this record. This includes the record's key size.
cbLongValueOverhead
The overhead of the long-value data.
Note This does not count intrinsic long-values.
cNonTaggedColumns
Total number of fixed and variable columns set in this record.
cTaggedColumns
Total number of tagged columns set in this record.
cLongValues
Total number of long values stored in the long-value tree for this record.
Note This does not count intrinsic long-values.
cMultiValues
The accumulation of the total number of values beyond the first for all columns in the record.
Remarks
The total number of values in the record would be cMultiValues + cNonTaggedColumns + cTaggedColumns.
