Sql server 2012 将varchar值“”转换为int数据类型时，转换失败

我在下面有一个查询，其中没有out count函数。我得到了答案，如果使用count函数，我得到了这个错误-->将varchar值“转换为int数据类型时，转换失败

请严厉批评我

 select 'INSERT INTO CM_ONTHEFLYCOMMUNICATION (c_source,c_classification,c_name,c_email,c_mobile,c_bookscount) 
      values ( '''+'Library'+''','''+isnull('CheckOut -'+cio_branchname,'')+''',
      '''+ISNULL(cio_membername,'')+''','''+ISNULL(mstmember.m_email1,'')+''',
      '''+ISNULL(mstmember.m_mobile,'')+''','''+count(trncheckinout.cio_bookname)+''')' 

     AS MAILQRY
     from 
    trncheckinout inner join
    mstmember on cio_mrecid=m_recid where CIO_CheckOutDt = 20141208
    group by m_email1,m_mobile, cio_branchname,cio_membername

你试过康卡特吗

select CONCAT('INSERT INTO CM_ONTHEFLYCOMMUNICATION (c_source,c_classification,c_name,c_email,c_mobile,c_bookscount) 
  values ( '''+'Library'+''','''+isnull('CheckOut -'+cio_branchname,'')+''',
  '''+ISNULL(cio_membername,'')+''','''+ISNULL(mstmember.m_email1,'')+''',
  '''+ISNULL(mstmember.m_mobile,'')+''','''+count(trncheckinout.cio_bookname)+''')')
AS MAILQRY
 from 
trncheckinout inner join
mstmember on cio_mrecid=m_recid where CIO_CheckOutDt = 20141208
group by m_email1,m_mobile, cio_branchname,cio_membername
