Parent class. NdbIndexScanOperation
Description.
IndexBound is a structure used to describe
index scan bounds for NdbRecord scans. It is
available beginning with MySQL Cluster NDB 6.2.3.
Members. These are shown in the following table:
| Name | Type | Description |
|---|---|---|
low_key |
const char* |
Row containing lower bound for scan (or NULL for scan
from the start). |
low_key_count |
Uint32 |
Number of columns in lower bound (for bounding by partial prefix). |
low_inclusive |
bool |
True for <= relation, false for
<. |
high_key |
const char* |
Row containing upper bound for scan (or NULL for scan
to the end). |
high_key_count |
Uint32 |
Number of columns in upper bound (for bounding by partial prefix). |
high_inclusive |
bool |
True for >= relation, false for
>. |
range_no |
Uint32 |
Value to identify this bound; may be read using the
get_range_no() method (see
Section 2.3.13.2.1, “NdbIndexScanOperation::get_range_no()”).
This value must be less than 8192 (set to zero if it is
not being used). For ordered scans,
range_no must be strictly increasing
for each range, or else the result set will not be
sorted correctly. |
For more information, see Section 2.3.25, “The NdbRecord Interface”.
