SELECT @SQL = 'SELECT '  

WHile @I <= @Months  
BEGIN  
      SET @YearMonth = REPLACE(LTRIM(SUBSTRING(CONVERT(VARCHAR, DateAdd(Month, @I, @StartDate), 13), 3,9)), ' ', '-')  
      SET @ColumnText = @YearMonth  
      SET @SQL = @SQL + 'ISNULL([' + @YearMonth + '], 0.00) as ''' + @ColumnText + ''','  
      SET @I = @I +1

最简单的方法是使用QUOTENAME()函数，因为在大型查询中很容易错过引用。例如：

DECLARE @name AS CHAR(10) = 'Revolver'       
DECLARE @sql as NVARCHAR(300) = 'SELECT *
FROM Music.Album
WHERE Name ='+ QUOTENAME(@name,'''')
PRINT @sql;

或

DECLARE @name AS CHAR(10) = 'Revolver'       
DECLARE @sql as NVARCHAR(300) = 'SELECT *
FROM Music.Album
WHERE Name ='''+ @name + ''''

PRINT @sql;

从字符串转换日期和/或时间时转换失败？
