SQL Error The multi-part identifier could not be bound - sql

Question

When I'm trying to execute this query, I get "The multi-part identifier "#EachEmployee.ResultID" could not be bound." error.
DECLARE #QueryText VARCHAR(1000)
SET #QueryText = '
UPDATE #EachEmployee2
SET #EachEmployee2.CorrectAnswerCount = (
SELECT COUNT (TMID)
FROM
' + #WorkDatabaseName + '.dbo.TestBlockTM AS TBTM,
' + #WorkDatabaseName + '.dbo.TestResultTM AS TRTM
WHERE 1 = 1
AND TBTM.TMID = TRTM.OtvetID
AND TBTM.TMPID = TRTM.VoprosID
AND TRTM.TestResultID = #EachEmployee2.ResultID
)
WHERE
#EachEmployee2.IsGroup = 0 AND #EachEmployee2.BlockID = 1'
EXECUTE(#QueryText)
However, the similar query is working perfectly:
UPDATE #EachEmployee2
SET #EachEmployee2.ResultID = (
SELECT TOP 1 TestResultID
FROM #AnswersList AS a
WHERE 1 = 1
AND a.SID = #EachEmployee2.SID
AND a.UserID = #EachEmployee2.UserID
)
Can someone tell what's a problem here? Thanks and appreciate your help.

Answer 1

try this
SET #QueryText = '
UPDATE emp
SET emp.CorrectAnswerCount = (
SELECT COUNT (TMID)
FROM
' + #WorkDatabaseName + '.dbo.TestBlockTM AS TBTM,
' + #WorkDatabaseName + '.dbo.TestResultTM AS TRTM
WHERE 1 = 1
AND TBTM.TMID = TRTM.OtvetID
AND TBTM.TMPID = TRTM.VoprosID
AND TRTM.TestResultID = emp.ResultID
)
From #EachEmployee2 emp
WHERE
emp.IsGroup = 0 AND emp.BlockID = 1'

Answer 2

Can you try this query and tell me if the error still occurs:
SET #QueryText = '
UPDATE #EachEmployee2
SET CorrectAnswerCount = (
SELECT COUNT (TMID)
FROM
' + #WorkDatabaseName + '.dbo.TestBlockTM AS TBTM,
INNER JOIN ' + #WorkDatabaseName + '.dbo.TestResultTM AS TRTM ON TRTM.OtvetID = TBTM.TMID
AND TRTM.VoprosID = TBTM.TMPID
AND TRTM.TestResultID = E.ResultID
)
FROM #EachEmployee2 E
WHERE E.IsGroup = 0
AND E.BlockID = 1'
I added the FROM clause and modified a bit the subquery in order to replace the old SQL syntax by an explicit INNER JOIN clause.
Hope this will help
