public short[] getPartitionKeyBindVariableIndexes(TableMetadata metadata)
```
    Returns an array with the same length as the number of partition key columns for the table corresponding to table. Each short in the array represents the bind index of the marker that holds the value for that partition key column. If there are no bind markers for any of the partition key columns, null is returned. Callers of this method should ensure that all statements operate on the same table.
