Select Field Sequence to Display

This panel is accessed by pressing "F14=Fields" on the main panel. This panel is used to:

• Display the File Field Descriptions (FFD's) and the Keys to the file

• Resequence the fields into any order you wish

• Hide any fields you do not want to display

• "Lock down" any fields that you always want to display. This is particularly useful for Keys (F15)

• You also have the ability to "Save" and "Restore" field sequences for later use. This is handy for working with the same database file over and over again

• A F16=Find function (by Field Name or Field Text) is provided to quickly take you to matching Fields you wish to work with

Executing SQL Commands

Pressing "F18=SQL Cmds" on the main panel allows you to execute SQL operations with your data base file. The SQL functionality is implemented via QMQRY (query management query) that is a normal part of OS/400. You are not required to purchase any additional SQL licensed product.

The SQL commands available are:

• Select
• Count
• Update
• Delete
• Label (change Field Text and/or Column Headings
• Insert

SQL operations can optionally be executed in batch. They can also be saved, then using a special command (WRKDBFSQL), they can be executed at a later date/time

The selected data can be saved to either an iSeries database *OUTFILE or to an IFS *STMF.

A global "undelete" command (WRKDBFUNDL) is provided should you need the ability to "undelete" every deleted record in a file
