ORA-00904: “FORMAT”: invalid identifier
Pergunta
I am trying to format a date:
FORMAT(table.TCKT.TCKT_ISS_DATE, 'YYYY') AS TICKETYEAR
but I am getting the following error:
ORA-00904: "FORMAT": invalid identifier
Right now the date show the complete timestamp. Any suggestions on how to fix this problem, or any other way to format the date to just show the four digit year?
Solução
Use this function:
TO_CHAR(table.TCKT.TCKT_ISS_DATE, 'YYYY') AS TICKETYEAR
Outras dicas
You want to use TO_CHAR
instead of FORMAT
here, like this:
TO_CHAR(table.TCKT.TCKT_ISS_DATE, 'YYYY') AS TICKETYEAR
Oracle uses TO_CHAR
for string casting, you can see here for additional format options.
There's also the option of using EXTRACT()
which is ANSI-standard and portable:
EXTRACT(YEAR FROM table.TCKT.TCKT_ISS_DATE) AS ticketyear
