Formatting dates
Eve from the Business Intelligence (BI) team lets you know that she's gonna need your help to write queries for reports. The reports are read by C-level execs, so they need to be as readable and quick to scan as possible. Eve tells you that the C-level execs' preferred date format is something like Friday 01, June 2018 for 2018-06-01.
You have a list of useful patterns.
| Pattern | Description |
|---|---|
DD |
Day number (01 - 31) |
FMDay |
Full day name (Monday, Tuesday, etc.) |
FMMonth |
Full month name (January, February, etc.) |
YYYY |
Full 4-digit year (2018, 2019, etc.) |
Figure out the format string that formats 2018-06-01 as "Friday 01, June 2018" when using TO_CHAR.
