Know Your Data

• Where are the data entered on Banner forms?

• How do the Banner forms correspond to the Oracle tables in the database?

• What are the relationships between data in different tables?

For Example

• If you want to find the number of female applicants, you need to know– How is an applicant entered in Banner?– How is a person’s gender entered in Banner?

• It takes time and experience to gain knowledge of the system.

Know the Tables

• Normally, a table corresponds to a block of a Banner form.

• The naming convention for tables is similar to that for forms.– Seven characters

Table Names

• 1st character - System

• 2nd character - Module

• 3rd character - Type of table– Base, Repeating, and Virtual (or View)

• 4th - 7th characters -

Abbreviation of table purpose

Examples

• SPBPERS is the base table corresponding to the General Person Form–SPAPERS.

• SPRIDEN is the repeating table corresponding to the identification information block of the Identification Form–SPAIDEN.

Examples (continued)

• SPRADDR is the repeating table corresponding to the address information block of SPAIDEN.

• SPVADDS is a virtual table (or view) created to give current name and address information.

Finding Table Names

• Use Dynamic Help from the Banner form.

• Consult the Banner Student Technical Reference Manual.

• Print the Data Element Dictionary from GURPDED.

Visualizing a Table

• Think of a table as a grid having rows and columns–similar to a spreadsheet.

• Each row of the grid corresponds to a record.

• Each column of the grid corresponds to a field in the record.

SQL Basics

• Standard Query Language

• Population Selection uses the SQL select statement.

SQL Select Statement

• Select __________ PIDM

• From__________ table name(s)

• Where __________ criteria

Select

• In a population selection you can select only PIDMs. (A Personal IDentification Master is an internal identification number that is created when person and non-person records are entered on SPAIDEN.)

From

• The From clause indicates which table in the database contains the information being used in the selection.– The From clause must include the table used in

the Select clause.– The From clause also must include any other

table(s) involved in the Where clause.

Example–SQL Select

• Select SPRIDEN_PIDM

• From SPRIDEN

• Where SPRIDEN_LAST_NAME = ‘Smith’

Another Example

• Select SPRIDEN_PIDM

• From SPRIDEN, SPBPERS

• Where SPRIDEN_LAST_NAME = ‘Smith’

• and SPBPERS_SEX = ‘F’
