predicate(1)

The easiest method for selecting the first in a set of elements is with a predicate of value 1.

The IXSCAN node detailed description shows that all of the 1, 680 leaf pages are scanned due to the lack of a matching predicate.

If BC mode is unavailable, append predicate [1] to the node-set expression that returned more than one node.

Using a UNION or an IN-list are two common ways to eliminate an OR in a predicate ( see Table 1).

Now step through the rows in Table 1 to explore index eligibility for each predicate.

Here we refer to step n (the CTE n) and join in step (n 1) using the same predicate used in CONNECT BY.

The filter factor is a number between 0 and 1 that estimates the proportion of rows in a table for which the predicate is true.

Once fetched into DB2 buffer pools, records in these pages are scanned and the stage-1 predicate is applied.

It then scans each record in the buffer pool to apply the stage-1 predicate.

Use BC mode, or append a predicate [1] onto the select expression.

The detailed description of the FETCH node shows that 18, 515. 602 records are estimated to survive the stage-1 predicate.

For example, if the user provides (t1. pending=1) as predicate, using a nested-loop join to go through a million rows will take a long time.
