how to convert a datetime to date in snowflake

[alepage]

Hello, I would like to convert a datetime and take the datepart in snowflake. The datepart(AUTHRSTN_DT) is not working.

How to do that?

AUTHRSTN_DT
05JUN2023:08:24:37.000000

Please note that AUTHRSTN_DT format is datetime25.6

authorisation_date=datepart(AUTHRSTN_DT);

If it's coming over as a legit datetime value into SAS it should work. However, if it's coming over as character then you'll have to convert it.

data g;
 AUTHRSTN_DT = '05JUN2023:08:24:37.000000';
 AUTHRSTN_DT_N = input(AUTHRSTN_DT ,datetime25.6);
 justDate = datepart(AUTHRSTN_DT_N );
 format justDate date9.;
run;

If using SAS/ACCESS to Snowflake libname, then you might need to use the DBSASTYPE option on the libname statement to ensure the column is treated as a SAS datetime.

What's the value of &accountingDate?

What happens if you run below? Do you get any eodreport_date with a select_flg=0 that you would have wanted to select?

data test;
  set inforce_auto_cntrctver_org;
  if eodreport_date <= &accountingdate. then select_flg=1;
  else select_flg=0;
run;

proc freq data=test;
  table eodreport_date*select_flg /nocol norow nopercent;;
run;

Hi @alepage 

if you are trying to pass this value over to Snowflake and use it there, then you may want to look at this SAS/ACCESS Interface to Snowflake

https://documentation.sas.com/doc/en/pgmsascdc/v_046/acreldb/n1d5j8d7wegfezn1irjj3hcrne1n.htm

Hope this helps

Why not ask SNOWFLAKE?

To do what? To load a SAS table into Snowflake or to use it in a where clause to query Snowflake?

If query: If you run Proc Contents against the Snowflake table what type and format does the column show?

What's not working with datepart()? You get an error, or an undesired result, or the query just runs forever?

If it's for a query formulated in SAS SQL, the column in Snowflake is of type DateTime and you want all rows matching a specific date then below query should work and also get pushed to the DB for execution

where '05JUN2023:00:00:00'dt <= AUTHRSTN_DT < '06JUN2023:00:00:00'dt
