Installed the RDBMS interface and shows installed correctly and created a Tag Distribution. It`s work is correct, it counts the number of values collected in the next scan

We have table and SQL-query file:
SELECT CONVERT(varchar(255),[pump_id]) AS PI_ALIAS,

               CONVERT(varchar(255), [value]) AS PI_VALUE,

               CONVERT(varchar, [timestamp], 104) +' '+CONVERT(varchar, [timestamp], 108) AS PI_TIMESTAMP,

               0 AS PI_STATUS

FROM [STUDENT].[dbo].[param_values] WHERE timestamp > ?;


Attributes of Tag Distribution

It works correct but this tag:


has "Bad Input"

what have i done wrong?
