Hi,

I have procedure which need to compare the varchar2 field. I tried different way but I am not able to put  single quote  during variable comparison. if I hardcode single quote with value then it works but i Need variable value different and not hardcoded.

here is the procedure:

CREATE OR REPLACE procedure ACCT_INFO_MKT_MAP1_upd

is
--formula :      680100.001*(430400/NS$TOTALBLDSRAZS)
      cursor inrec is
            select hyp_acct_no,frstcol,trim(sndcol)sndcol from ACCT_INFO_MKT_MAP1 ;

v_acct_no  ACCT_INFO_MKT_MAP1.HYP_ACCT_NO%type;
v_frstcol  ACCT_INFO_MKT_MAP1.frstcol%type;
v_sndcol   ACCT_INFO_MKT_MAP1.sndcol%type;
v_janval_frstcol  number(20);
v_janval_sndcol  number(20);
v_janval_total  number(20);
v_err_no  varchar2(20);
v_err_msg  varchar2(200);
v_srt_tm  varchar2(20);
v_end_tm  varchar2(20);
v_sndcol1 varchar2(200);

-- first value is 430400  
--second value is  NS$TOTALBLDSRAZS

begin
      for rec in inrec loop
            exit when inrec%notfound;


            select jan_val into v_janval_sndcol
                        from HYP_ENT_HIST
                              where trim(hyp_acct_no)=TRIM('||v_sndcol1||') and acct_yr=1999;
                              

            select jan_val into v_janval_frstcol
                        from HYP_ENT_HIST
                              where trim(hyp_acct_no)=trim(rec.frstcol) and acct_yr=1999;
/* I am getting problem while comparing the second varchar value
both columns are varchar2 and same length.
 the select statemnt is like
   select jan_val v_janval_frstcol
                        from HYP_ENT_HIST
                              where trim(hyp_acct_no)='NS$TOTALBLDSRAZS ' and acct_yr=1999;
                              then it works fine
      */

            update ACCT_INFO_MKT_MAP1
                        set total=nvl(rec.hyp_acct_no*(v_janval_frstcol/(v_janval_sndcol)),0)
                              where hyp_acct_no=trim(rec.hyp_acct_no) ;                              

            end loop;
            commit;
                  
end;
/

/* I am getting problem while comparing the second value
it the select statemnt is like
   select jan_val v_janval_frstcol
                        from HYP_ENT_HIST
                              where trim(hyp_acct_no)='NS$TOTALBLDSRAZS ' and acct_yr=1999;
                              then it works fine
      */

1)  how to put single quote for variable in procedure?
2) incase query returns more then one row then how to avoid that?


Thank you very much in advance.

If this works
   select jan_val v_janval_frstcol
                    from HYP_ENT_HIST
                         where trim(hyp_acct_no)='NS$TOTALBLDSRAZS ' and acct_yr=1999;
                         then it works fine
and this doesn't
         select jan_val into v_janval_frstcol
                    from HYP_ENT_HIST
                         where trim(hyp_acct_no)=trim(rec.frstcol) and acct_yr=1999;
then trim(rec.frstcol) doesn't match 'NS$TOTALBLDSRAZS '
The last character looks like a space, but if the trim isn't getting rid of it, could be a tab or something more ugly.
do a
select distinct ascii(substr(trim(hyp_acct_no),length(trim(hyp_acct_no)))) from HYP_ENT_HIST

I use the following to strip out all non-uppercase letters from a string. If you include all the characters you want in the string, it will strip out all the others (tabs, carriage retuns etc).
updat table set col =  
translate(col,' '||translate(col,' ABCDEFGHIJKLMNOPQRTSUVWXYZ',' '),' ') a

Hi gmyers,

How are you? I appreciate your prompt help. Thank you very much. It was my mistake while comparing the wrong column. I was in hurry and didn't realise the problem.

 I am comparing the  
          select jan_val into v_janval_sndcol
                    from HYP_ENT_HIST
                         where trim(hyp_acct_no)=TRIM('||v_sndcol1||') and acct_yr=1999;

should be

          select jan_val into v_janval_sndcol
                    from HYP_ENT_HIST
                         where trim(hyp_acct_no)=TRIM(rec.hyp_acct_no) and acct_yr=1999;

sorry for that.

Once again thank you very much.
