SELECT @columns = COALESCE(@columns + ',[' + cast(Date as varchar) + ']',
'[' + cast(Date as varchar)+ ']')
FROM Absence
GROUP BY Date DECLARE @query VARCHAR(8000) SET @query = ' SELECT * FROM (SELECT Name , Code, Section, Date FROM Absence) up PIVOT (COUNT(Code) FOR Date IN (' + @columns + '))  AS p WHERE Section LIKE A ' EXECUTE(@query)

Solution 1

You have delimit a single quote for LIKE:

SQL

GROUP BY Date DECLARE @query VARCHAR(8000) SET @query = ' SELECT * FROM (SELECT Name , Code, Section, Date FROM Absence) up PIVOT (COUNT() FOR Date IN (' + @columns + '))  AS p WHERE Section LIKE ''A'' ' EXECUTE(@query)

sir, what if in the where clause is "WHERE Year(CreateDate) = ' +@YEAR+ '", it would say invalid column name CreateDate but i have checked it with nothing wrong.
