Check cdmTable and cdmField error in query

[dassagichnicht]

In the check "cdmTable" the most inner select statement is the following
SELECT CASE WHEN COUNT(*) = 0 THEN 0 ELSE 0 END AS num_violated_rows FROM hob_valid.CONDITION_OCCURRENCE cdmTable GROUP BY 1
However, this query results in 0 rows if the table is empty.

I think deleting the GROUP BY 1 solves the issue.

The same holds true for the check "cdmField".

Unfortunately, I couldn't find the files in which the checks are defined to check if the problem is still there or if I'm just using an old version.

Please let me know what version of DataQualityDashboard you are running. The GROUP BY clause is not in the current source SQL for this check: https://github.com/OHDSI/DataQualityDashboard/blob/main/inst/sql/sql_server/table_cdm_table.sql. However, if you are on the latest version of the package it's possible this is a SqlRender issue.
