Can we merge 2 SQL with same logic with just marginally difference? - sql

Question

I have 2 SQLs,
SELECT #AlreadyPerformedActionsPerDay = COUNT(*)
FROM UserRewardActions URA
INNER JOIN UserRewardActionTypes URAT ON URAT.ID = URA.UserRewardActionTypeID
WHERE URA.UserID = #UserID
AND (
#UserRewardActionTypeID = 1 -- Because the register action is not per-date-wise(only allows once in lifetime)
OR CreationDateInUtc BETWEEN CAST(GETUTCDATE() AS DATE) AND DATEADD(DAY, 1, CAST(GETUTCDATE() AS DATE)) -- Inside Current Date
);
SELECT #AlreadyRedeemedTheCurrentAction = 1
FROM UserRewardActions URA
INNER JOIN UserRewardActionTypes URAT ON URAT.ID = URA.UserRewardActionTypeID
WHERE URA.UserID = #UserID
AND CreationDateInUtc BETWEEN CAST(GETUTCDATE() AS DATE) AND DATEADD(DAY, 1, CAST(GETUTCDATE() AS DATE)) -- Inside Current Date
AND URL IS NOT NULL
AND URL = #Url;
The fist SQL is the grabbing total number of user actions today. Second, is checking whether the current url is already used by the same user. This is fine. But I am looking to merge this query for performance issue.

Answer 1

well, after reformatting your queries as below. I can see that they have different criteria.
DECLARE #from DateTime;
DECLARE #to DateTime;
SET #from = cast(getutcdate() as Date);
SET #to = dateadd(DAY, 1, #from));
SELECT
#AlreadyPerformedActionsPerDay = COUNT(*)
FROM
UserRewardActions URA
JOIN
UserRewardActionTypes URAT
ON URAT.ID = URA.UserRewardActionTypeID
WHERE
URA.UserID = #UserID
AND
(
#UserRewardActionTypeID = 1
OR
CreationDateInUtc BETWEEN #from AND #to
);
SELECT
#AlreadyRedeemedTheCurrentAction = 1
FROM
UserRewardActions URA
JOIN
UserRewardActionTypes URAT
ON URAT.ID = URA.UserRewardActionTypeID
WHERE
URA.UserID = #UserID
AND
CreationDateInUtc BETWEEN #from AND #to
AND
URL IS NOT NULL
AND
URL = #Url;
