Fixed a critical bug introduced by the new code that cleans the window order remaining in database output. The problem is related to this issue Inability to remove window_order() leads to weird, unpredictable results.
bind_source() will bind correctly if every variable name argument is a single string (i.e., selecting variables with common names only).
Fixed a bug in pool_case() when every source had all the flags, the code that fills missing flag == 1 would trigger an error.
fetch_var() will accept database input, but it will not prevent one-to-many joins because the checking could be slow on remote database.
All functions that accept database input now will NOT sort the output to avoid generating the ‘ORDER BY’ clause which may trigger a warning if the output was chained with subsequent operations.
restrict_date() will not check missing date unless the new check_missing argument was set to TRUE. The checking time may be not negligible for large database; the user should opt in for it.
The apart argument in restrict_date() is now functional for both data.frame and database input.
restrict_date() will give warning if there are missing entries in date_var. The description of dup.rm has been re-written to clarify it is applicable only when apart is absent.
pool_case() now outputs both the number of raw (raw_in_src) and valid (valid_in_src) entries in each source.
List element of execute_def() output is named by definition and source labels.
Most of the verbose message, except data summaries, will be sent as message instead of text output, so that they can be suppressed via message = FALSE in Rmarkdown.
detail and dup.rm are both TRUE. if_date() now does not assume the dates are sorted and returns elements in the original unsorted order.
