我以这种方式排序问题

 Begin
 execute 'select count(*) from ' ||tablename||
' where cast(date_dimension_year || ''-'' || date_dimension_month || ''-''||date_dimension_day as date) 
not between (current_date - interval ''13 months'') and current_date' into total ;

我必须指定整数总和结束，正确关闭引号。

I had to assign the integer total towards the end and proper closing of quotation (') worked for me.( I just pasted a portion of the function where i was getting issue)

感谢您的帮助。
