Answer 1

你试过CONCAT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
