         Hi,
 
            It is not possible to access a local variable in EXECUTE Command and give a syntax error. FOR..IN..LOOP is the best option
            
            CREATE OR REPLACE FUNCTION TestQry( vCon teXt )
            RETURNS VARCHAR AS $$
            DECLARE
               var1 varchar(10);
               var2 varchar(10);
               result varchar( 20 ); 
               rRec  RECORD; 
            BEGIN
   
                 FOR rRec IN EXECUTE( 'SELECT A1,A2 FROM  '||vCon ) LOOP
                       var1 = rRec.A1;
                       var2 = rRec.A2;
                 END LOOP;
  
               RETURN VAR1||VAR2;
   
            END;
            $$ LANGUAGE 'plpgsql';
 
         Regards,
         R.Muralidharan.

Hi

 

What’s wrong with this code (ERROR:  syntax error at or near "INTO" at character 8)?

 

Problem: I want to put A1, A2 values in two variables vara, varb.

 

CREATE OR REPLACE FUNCTION test(text)

RETURNS VARCHAR AS $$

Declare

          vara    VARCHAR(10) :='';

          varb    VARCHAR(10) :='';

          result  VARCHAR(10) :='Result';

         

BEGIN          

          EXECUTE(

                   'Select INTO vara, varb A1, A2 from '|| $1

          );

         

RETURN result||': '|| vara ||' '|| varb;

 

END;

$$ LANGUAGE plpgsql;

 

 

Regards
Dinesh Pandey
