SELECT only the columns needed

Friday, October 16th, 2009

Every column that is selected has to be individually handed back to the calling program, unless there is a precise match to the entire DCLGEN definition.

This may lean you towards requesting all columns, however, the real harm occurs when a sort is required. Every SELECTed column, with the sorting columns repeated, makes up the width of the sort work file wider. (more…)

SELECT only the rows needed

Friday, October 16th, 2009

The less rows retrieved, the faster the query will run. Each qualifying row has to make it through the long journey from storage, through the buffer pool, Stage 1, Stage 2, possible sort and translations, and then deliver the result set to the calling program. (more…)

Sequence filtering from most restrictive to least restrictive by table, by predicate type

Friday, October 16th, 2009

When writing a SQL statement with multiple predicates, determine the predicate that will filter
out the most data from the result set and place that predicate at the start of the list. By
sequencing your predicates in this manner, the subsequent predicates will have less data to
filter. (more…)

Make numeric and date data types match

Saturday, October 3rd, 2009

Stage 1 processing has been very strict in prior releases about processing predicate compares
where the datatype lengths vary.

Prior to DB2 v7, this mismatch led to the predicate being demoted to stage 2 processing. However, a new feature in DB2 v7 allows numeric datatypes to be manually cast to avoid this stage 2 demotion.

ON DECIMAL(A.INTCOL, 7, 0) = B.DECICOL
ON A.INTCOL = INTEGER(B.DECICOL)

If both columns are indexed, cast the column belonging to the larger result set. If only one
column is indexed, cast the partner. A rebind is necessary to receive the promotion to Stage 1.

How to Avoid Getting Your Emails Flagged as Spam

Saturday, October 3rd, 2009

The first step to successful email marketing is actually getting your emails delivered so they can be read.

There are several things you want to keep in mind when sending out emails to make sure you stay on an email provider’s good side.

Promote Stage 2 & Stage 1 Predicates if Possible

Friday, October 2nd, 2009

Either the Stage 1 Data Manager or the Stage 2 Relational Data Server will process every query. There are tremendous performance benefits to be gained when your query can be processed as Stage 1 rather than Stage 2. The predicates used to qualify your query will determine whether your query can be processed in Stage 1. In addition, each predicate is evaluated to determine whether that predicate is eligible for index access. There are some predicates that can never be processed as Stage 1 or never eligible for an index. It’s important to understand if your query is indexable and can be processed as Stage 1. The following are the documented Stage 1 or Sargable predicates: (more…)
