I can not convert the sql query...

Hello experts, I have this query ( I brought it from ms access) and I can't convert it to a valid pl sql query can anyone help me?

SELECT TEMP_DIEUTHINSEIS_CODES.TXTAXC1, substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,0,5) AS ODOS_CODE,
substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,6,3) AS ADDRESSNUM, TEMP_DIAMERISMATA.APARTMENTNUM AS APARTMENTNUM,
substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,0,2) AS ZONIID, TEMP_DIEU_KAT_KTIRIOU_2.KAT_KTIR,
decode(length(substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,0,2))=2,"0","") + substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,0,2) AS SECONDARY_CODE,
substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,6,3) AS FIRST_CODE
decode(TEMP_MAIL_ADDRESS_AR_ACC.COADR3 Like "*7101*",7101,decode(TEMP_MAIL_ADDRESS_AR_ACC.COADR3 Like "*7102*",7102,
decode(TEMP_MAIL_ADDRESS_AR_ACC.COADR3 Like "*7103*",7103,decode(TEMP_MAIL_ADDRESS_AR_ACC.COADR3 Like "*7104*",7104,0)))) AS POSTCODE
FROM TEMP_DIEUTHINSEIS_CODES
LEFT JOIN TEMP_DIEU_KAT_KTIRIOU_2 ON TEMP_DIEUTHINSEIS_CODES.TXTAXC1=TEMP_DIEU_KAT_KTIRIOU_2.TXTAXC
LEFT JOIN TEMP_DIAMERISMATA ON TEMP_DIEUTHINSEIS_CODES.TXTAXC1=TEMP_DIAMERISMATA.DIEUTHINSI_CODE
INNER JOIN TEMP_ODOSID_TAXNUMBER ON TEMP_ODOSID_TAXNUMBER.txtaxc = substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,0,5)
INNER JOIN TEMP_MAIL_ADDRESS_AR_ACC ON TEMP_ODOSID_TAXNUMBER .TXTAXP=TEMP_MAIL_ADDRESS_AR_ACC.COCODE;

I have changed the below :

changed * to %
changed " to '
changed to use CASE instead of DECODE accordingly
change + to ||
and so on...

I think you are trying to use DECODE as IIF. Instead
change

decode(length(substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,0,2))=2,"0","")

to

decode(length(substr(TEMP_DIEUTHINSEIS_CODES.TXTAXC1,0,2)),2,"0","")

IIF ( true, if-true, else )
DECODE( something, look-for, if-true, else )
Decode has other variants, like having multiple things to look for

DECODE( something, look-for, if-matched, look-for-2, if-matched-2, ... , else )
