decimal to datetime conversion

[former_member198401]

Hi All,

I want to convert decimal values to datetime values. Looks silly but its kind of tricky 🙂

for e.g

20170723231018 value has decimal(15,0)

20170723231018.1340000 value has decimal(21,7)

I converted the decimal value to varchar and it gets converted but when I try to convert the varchar string to datetime using to_date() it says that it cannot convert the string to date format YYYY.MM.DD

Target Table is HANA and Source is SAP BW table

Any help or hint would be appreciated.

Regards

Arun Sasi

Cast to varhcar(14) for Date with Timestamp
to_date(CAST(DATETIME,'VARCHAR(14)'),'YYYYMMDDHH24MISS')

Output will be in datetime column

2017.07.23 23:10:18.000000000

Cast to varchar(22) and then convert to datetime for including Date with timestamp with sub seconds
to_date(CAST(DATETIME_SUBSECONDS,'VARCHAR(22)'),'YYYYMMDDHH24MISS.FF')

Output:

2017.07.24 00:13:47.420000000
