Don't let a library of useful but outdated queries stop you from modernizing how you deliver your data.

heath kathWritten by Heath Kath

Are you still running IBM i green-screen queries? How many queries are you dealing with? Are you finding it hard to manage all those queries? Are your users tired of waiting for a slow-running query that can use only the Classic Query Engine (CQE)? Would your users prefer a modern, graphical interface with more distribution options?

Use the table function equivalents of Display Record Lock (DSPRCDLCK) and Work with Object Locks (WRKOBJLCK) in your SQL code.

Written by Michael Sansoterra

If you've ever wanted to yell at users and tell them to exit a specific screen (or wanted to just happily end their job automatically) because they're locking a record, then this tip is for you. Best of all, you'll be able to use this functionality right from the comfort of your SQL code.

Increase your database understanding with this free IBM tool.

kent milligan 117x117Written by Kent Milligan

Your physical database implementation plays a key role in the performance and extensibility of your application. Because the AS/400's integrated relational database was so easy to use, many programmers created physical files and logical files without giving much thought to the database model. This approach has resulted in many unwieldy physical databases that are hard to understand.

Wouldn't it be nice if big data access was fast and easy with minimal setup time or struggle?

heath kathWritten by Heath Kath

Big data: This term covers a lot of ground. With no definitive dividing line based on file size, data type, number of records, or job requirements, how do you know if you're doing big data? Ask yourself, has the size or speed requirements of new analytic initiatives put serious strain on existing IT infrastructure? Most organizations could say yes because big data is everywhere.

TechTip: Keep DB2 Routines in Synch Across Systems PDF Print E-mail

A new assessment utility makes it easy to keep stored procedures and functions synchronized!

kent milligan 117x117Written by Kent Milligan

As more IBM i applications utilize stored procedures and user-defined functions, processes must be put in place to manage these routines just like traditional IBM i program objects. You need to make sure the stored procedures and functions are moved from your development system to production system to ensure that that the application is able to run. Likewise, if you have a backup system that's used for disaster recovery, the routines also need to be propagated to the backup system.

TechTip: Compress Large Object (LOB) Data in DB2 for i PDF Print E-mail

Implement these user-defined functions to save space when storing large amounts of data.

Written by Michael Sansoterra

In modern applications, it's typical to store large amounts of text data, including emails, rich text documents, audit logs, and XML. Recording this information in a database table can impose a significant tax on disk space. However, using a compression algorithm can alleviate this tax. In this tip, I'll demonstrate two user-defined functions that implement ZLib compression to deflate and inflate data that is stored or accessed via DB2 as a large object data type (BLOB, CLOB, and XML).

Emulate the window aggregate functions available on other database platforms.

Written by Michael Sansoterra

A friend recently asked me how to convert a particular Oracle query to SQL Server 2005. The query contained a column expression that looked like this (modified and simplified):

 

SELECT AVG(AMOUNT)

OVER(ORDER BY TDATE ROWS BETWEEN 6 PRECEDING AND CURRENT ROW)

FROM ORDER_SUMMARY

ORDER BY AMOUNT DESC
