Обсуждение: MS-SQL to PostgreSQL

Hi

Below is a snippet of MS-SQL code. Please can someone translate this to
plpgsql for me.

**************************************************************
DECLARE @MaxVal int, @MinVal int

SELECT @MaxVal = MAX(Value), @MinVal = MIN(Value)
FROM ABC
**************************************************************

The variables would then be used for purther processing.
I know that the variables would be declared like

*******************************************
DECLARE
    MaxVal int;
    MinVal int;
BEGIN
   ???
END;
*******************************************

I am not sure of the query part and in particular the assignment of the
values to the variables

Thank you
Craig

See SELECT INTO in the PL/pgSQL documentation.

Hi Craig....

try with this....

Declare v_maxval integer; v_minval integer;
Begin
   Select max(value),min(value) into v_maxval,v_minval from ABC;

end;

or see SELECT INTO from postgresql documentation
