SQL cmd.command 包含 OR 语句

Question

下面是我的SQLcmd.CommandText查询：

cmd.CommandText = "SELECT CONVERT(date, [DateTime]) 'Date of Download', ActionBy AS 'User Full Name', COUNT(DISTINCT CAST(Identifier AS NVARCHAR(10)) + Remarks + Link) 'Number of Document Downloads' " + 
    " FROM [dbo].[AuditLog] "+
    " WHERE ActionTaken = 'Clicked' "+
    " and Type = 'Attachment Link'" +
    " and CONVERT(date, [DateTime]) BETWEEN CONVERT(date,'" + scanStartDate.ToString("yyyy-MM-dd HH:mm:ss.fff") + "') and CONVERT(date,'" + scanEndDate.ToString("yyyy-MM-dd HH:mm:ss.fff") + "') "+
    " GROUP BY CONVERT(date, [DateTime]), ActionBy "+
    " HAVING COUNT(DISTINCT Identifier) > " + limit + 
    " ORDER BY COUNT(DISTINCT Identifier) DESC";

我想为 Type 添加一个额外的参数 OR，如下所示：

" and Type = 'Attachment Link' OR 'Attachment Link - Search'" +

请问如何实现？

谢谢。

编辑：抱歉，没有在错误信息中添加，如下。

An expression of non-boolean type specified in a context where a condition is expected, near 'and'.

我假设我过度简化了，但你的意思是：

cmd.CommandText = "SELECT CONVERT(date, [DateTime]) 'Date of Download', ActionBy AS 'User Full Name', COUNT(DISTINCT CAST(Identifier AS NVARCHAR(10)) + Remarks + Link) 'Number of Document Downloads' " + 
    " FROM [dbo].[AuditLog] "+
    " WHERE ActionTaken = 'Clicked' "+
    " and (Type = 'Attachment Link' OR Type = 'Attachment Link - Search') " +
    " and CONVERT(date, [DateTime]) BETWEEN CONVERT(date,'" + scanStartDate.ToString("yyyy-MM-dd HH:mm:ss.fff") + "') and CONVERT(date,'" + scanEndDate.ToString("yyyy-MM-dd HH:mm:ss.fff") + "') "+
    " GROUP BY CONVERT(date, [DateTime]), ActionBy "+
    " HAVING COUNT(DISTINCT Identifier) > " + limit + 
    " ORDER BY COUNT(DISTINCT Identifier) DESC";

您可能需要 ( ) 作为操作顺序，我认为您的意思是“=”而不是“-”。

在您的 OR 运算符之后指定列

cmd.CommandText = "SELECT CONVERT(date, [DateTime]) 'Date of Download', ActionBy AS 'User Full Name', COUNT(DISTINCT CAST(Identifier AS NVARCHAR(10)) + Remarks + Link) 'Number of Document Downloads' " + 
        " FROM [dbo].[AuditLog] "+
        " WHERE ActionTaken = 'Clicked' "+
        " and (Type = 'Attachment Link' OR Type = 'Attachment Link - Search') " +
        " and CONVERT(date, [DateTime]) BETWEEN CONVERT(date,'" + scanStartDate.ToString("yyyy-MM-dd HH:mm:ss.fff") + "') and CONVERT(date,'" + scanEndDate.ToString("yyyy-MM-dd HH:mm:ss.fff") + "') "+
        " GROUP BY CONVERT(date, [DateTime]), ActionBy "+
        " HAVING COUNT(DISTINCT Identifier) > " + limit + 
        " ORDER BY COUNT(DISTINCT Identifier) DESC";
