Applying formats to compued vars

Hi,

it would be very helpful if formats could be applied to computed variables - especially when working with date/time columns. The functionality seems to be there, but it's breaking the table reference.

Example: Based on a datetime column I can successfully add a time column that holds the hour of the datetime column.

# example table
conn.datastep.runCode(
	code =
	'''data test;
		format datetime e8601dt19.;
		datetime = dhms("03mar2024"d, 9, 50, 0);
		price    = 101.4;
		output;
		datetime = dhms("03mar2024"d, 10, 20, 0);
		price    = 102.5;
		output;
	run;''',
	single = 'yes'
)
tbl = conn.CASTable('test')

# add column containing the hour of the datetime column
tbl['time'] = tbl['datetime'].dt.hour*60*60

# apply time format to new column
tbl.computedvars = [{'name':'time', 'format':'time8.'}]

# check if time format was applied
tbl.columnInfo()

# check if time format works
tbl.head()

Unfortunately, after applying the format as shown above, I can't execute any operations on the table anymore:

tbl[tbl['price']>=102].head()

Commencez par exécuter la reproduction Python fournie avec CASTable, computedvars, columnInfo() et l’appel filtré à head(). Suivez l’impact de l’application du format à la colonne temporelle calculée sur les opérations ultérieures de la table, et considérez le problème comme résolu lorsque le format est conservé tandis que le filtrage de tbl par price s’exécute toujours correctement.
