The document outlines a requirement to transform a column from a view in Oracle PL/SQL by separating department names into group and subgroup. It specifies using the substr and instr functions to achieve this, with an example of how the department should be parsed. The desired output is a view that includes username, group, subgroup, and several additional columns.

1. Oracle PL/SQL Substr and Instr: I have a view (not table) with column names USERNAME,
DEPARTMENT, FINANCE (FN), RESOURCES(HR), BUDGET(BD), from a table called Groups. I
need to make the Department into a GROUP and SUBGROUP by using substr and instr to
separate the different parts of the departments. I need to see the view return Username, Group,
Subgroup, FN, HR, and BD. For example, If a department is called MC-DOLL-FN then I need it to
be returned as MC-DOLL in the group, and FN in the subgroup. Please help.
