带有sysdate的案例声明

Question

Good day all. I have an Excel workbook that has an ODBC connection to an oracle database. I have a query built into the command text to pull down some data. I am rather new at doing this stuff and I recently learned of the existence of "case" statements, but I have no clue as to what I am doing.

I am looking for the proper state to produce the following result

If Table.Datefield is less or equal to System Date - 14 days then show "New" If Table.Datefield is greater than System Date - 14 days then show "Waiting Approval".

I have tried

    case 
when "Table"."APPROVEDON" > sysdate - 14 then 'New'
when "Table"."APPROVEDON" < sysdate - 14 then 'Waiting Approval'
else 'N/A'
end as "Status"

However, I get a missing expression error.

As I said I am very new to this. I tried some searching, but I am unsure of what to really search for.

Answer 1

As it is the wrong syntax it was throwing an error. Try this.

CASE //columnName//
when //tblname.columnname// > //columnname//- 14 then 'New'
when //tblname.columnname// < //columnname// - 14 then 'Waiting Approval'
else 'N/A'
end as "Status"

(you have to tell the query statement on which column you want to perform the case operation). Hope it helps !!
