字符连接问题，这是什么错误提示？？

通过FlatComboBox做选择条件查询，
为什么在FlatComboBox5.text加引号就出现如下错误，不加又可以通过，这是什么错误提示呢？？if FlatComboBox7.Text='包含' then
               term:=term+'sqaddr='+FlatComboBox12.Text+' and wcdate'+' like ''%'+FlatComboBox5.text+'%'''
          else
               term:=term+'sqaddr='+FlatComboBox12.Text+' and wcdate'+FlatComboBox7.text+''''FlatComboBox5.text'''';
[Error] gltj_9.pas(70): Missing operator or semicolon

Answer 1

if FlatComboBox7.Text='包含' then 
               term:=term+'sqaddr='+FlatComboBox12.Text+' and wcdate'+' like ''%'+FlatComboBox5.text+'%''' 
          else 
               term:=term+'sqaddr='+FlatComboBox12.Text+' and wcdate'+FlatComboBox7.text+''''FlatComboBox5.text''''; //这一句语法有错误，自己修改一下

Answer 2

第二句FlatComboBox5.Text两边少了两个加号,你的sqaddr应该是字段,如果是字符型的话,还要多加几个引号
if FlatComboBox7.Text='包含' then 
               term:=term+'sqaddr='''+FlatComboBox12.Text+''' and wcdate'+' like ''%'+FlatComboBox5.text+'%''' 
          else 
               term:=term+'sqaddr='+FlatComboBox12.Text+' and wcdate'+FlatComboBox7.text+''''+FlatComboBox5.text+''''; 

Answer 3

if FlatComboBox7.Text='包含' then 
    term:=term+'sqaddr='''+FlatComboBox12.Text+''' and wcdate'+' like ''%'+FlatComboBox5.text+'%''' 
  else 
   term:=term+'sqaddr='''+FlatComboBox12.Text+''' and wcdate'+FlatComboBox7.text+''''+FlatComboBox5.text+'''';
