healthdb 0.5.1

• Updated identify_row() to accommodate changes in upcoming ‘dbplyr’ release - Thanks the ‘dbplyr’ devs for the fix!

• fixed an error caused by changes in ‘data.table’

healthdb 0.5.0

Bug fix

• Fixed a bug in the apart feature in restrict_date() caused by ‘dbplyr’ 2.5.1 update where the input order of the SQL translation for difftime() was flipped.

Improvements

• Added a new define function with age restriction - define_case_with_age()

healthdb 0.4.1

Improvements

• Functions that take remote table as input now checks whether connection to database is working properly.

healthdb 0.4.0

Improvements

• fetch_var() documentation now indicates that it does not accept input from a pipe.
• collapse_episode() now works for remote table input.
• pool_case() now provides the source for the first valid and the latest records for linkage back to the source data.

healthdb 0.3.1

Bug fixes

• 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.

healthdb 0.3.0

Improvements

• 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.

Bug fixes

• Chaining pool_case() with dplyr::compute() to create table in database should no longer give errors or warnings related to window order.

healthdb 0.2.0

Improvements

• 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.

Bug fixes

• Fixed if_date() gave output shorter than the input when 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.
• Fixed restrict_date() for remote table might miss cases with duplicated dates when n > 2.
