In the most case, a query string expression on a date or time attribute can be written using a value placeholder. For example:

$entSel:=ds.TableName.query("dateField = :1";!2022-07-12!) $entSel:=ds.TableName.query("timeField = :1";?01:00:00?)

or

$entSel:=ds.TableName.query("dateField = :1";$dateVar) $entSel:=ds.TableName.query("timeField = :1";$timeVar)

If there is a need for the query string to be written (or injected) as a literal string expression, it must be in the following form.

$entSel:=ds.TableName.query("dateField = 2022-07-12") $entSel:=ds.TableName.query("timeField = 01:00:00")

The prefix and suffix (! and ?) for each type are unnecessary in this literal query expression.
