Your where condition in the sub-select is wrong. Replace

"Friday"

with

day = "Friday"

[radha009]

its typo i had 

proc sql;
create table sh1.table3 as
select * from sh1.table2 where Start_Date in (select date from sh1.table1 where day='Friday');
quit;

[Kurt_Bremser]

Then you have to look at the data.

Is day actually character, or could it be a number formatted to display day names?

Are your dates integer values? If imported from Excel, you might have fractions indicating times hidden.

PS: check the spelling of your day variable. 'friday' <> 'Friday'!

When I create data based on your pasted text and run a similar query I get 6 rows in the result.

data work.table1;
input day $ Date :mmddyy10.;
format date mmddyy10.;
datalines;
Friday 10/18/2019 
Saturday 10/19/2019 
Sunday 10/20/2019 
Monday 10/21/2019 
;
 

data work.table2;
   input Request :$10. ReleaseID :$10. Analyst $ Start_date :mmddyy10. AppID $ State $;
   format Start_date mmddyy10.;
datalines;

proc sql;
   create table work.deployments as
   select * from work.table2 
   where Start_date in (select Date from work.table1 where  'Friday');
quit;

If I use a likely more correct Sql code:

proc sql;
   create table work.deployments as
   select * from work.table2 
   where Start_date in (select Date from work.table1 where day= 'Friday');
quit;

I get 3 rows.

I make very sure that your Start_date and Date variables are both actually date values, with no decimal portion as @Kurt_Bremser mentions may happen with data starting from some sources. Or given some folks having a poor habit of referring to datetime values as "dates", make sure that is not the case here. You may have to print some values using a BEST format to check.

If the dates are actually character variables then check closely on there values as well. 

Also make sure that in your data set the variable Day does not have any leading spaces or trailing non-blank characters (null characters for example)
