Postgres - Passing table name as parameter and store result in file

Question

    Create Or Replace Function totalRecords (tablename TEXT) Returns integer as $total$
    Declare
      total integer;

      Begin
       select count  (*)  into  tot         


        

Answer 1

I sorted the issue this way

 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 ;

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)

Thanks for all your help.
