  1. Once a physical file has been created, how can data be loaded into it? • DFU • SQL • Copy File • Write a program

  2. List all of the steps required to create a program described file and to put data into it. • Use the CRTPF command to create the file with a specific record length • Use a ‘Copy’ command to copy data into the file, or SQL, or write a program, or DFU.

  3. Working with Query/400

  4. Query/400 • Report Generator Tool • Creates objects with the type *QRYDFN

  5. Query/400 does the following: • Selection and arrangement of records in a file • Selection and placement of fields • Specification of report breaks • Ability to examine a report layout and preview a report • Ability to print a report based on the contents of one or more files without programming. • Ability to create a file based on the contents of one or more files without programming.

  6. To access Query/400 use the commands: STRQRY or WRKQRY

  7. Creating A Query • Select option 1 from Work with Queries • Enter query name and library where it is to be stored • Press enter!

  8. Defining the Query • You are presented with a list of selections. Place a 1 in the opt field beside those you want to use. The only one you must choose is File Selection. • Choose other selections as needed for sorting, editing fields, selecting of records, defining new fields, selecting output type, etc.

  9. Query Demo • Single File • Multiple Files

  10. Helpful Tips • Remember to hit ENTER after making your selections • Use the ampersand (&) to indicate a space in edit words • You can use field names in text areas by specifying the field name with an & in front of it. Eg. &DEPT Totals would yield text of Accounting Totals if DEPT was Accounting

  11. Creating a Permanent DFU • STRDFU, option 2 to create a DFU • name the DFU and choose the file • define general information screen: accept defaults • define Audit control: accept defaults • work with record formats: select format • select and sequence fields • work w/fields: select #2 to change headings, do editing, validation, etc

  12. DFU demo
