You could use something like this:

Code:
_where=
for p; do
  [ -n "$_where" ] &&
    _where="$_where and $p" ||
      _where="where $p"    
done
      
select 
  col1, col2 ..
from
  table_name
"$_where";

And invoke the script like this:

Code:
./script_name 'col1 = val1' 'col2 = val2' ...

Consider the following example and output:

Code:
% cat s
_where=
for p; do
  [ -n "$_where" ] &&
    _where="$_where and $p" ||
      _where="where $p"    
done
      
cat << !
select 
  col1, col2 ..
from
  table_name
$_where;
!


Code:
% ksh s "col1 = 'val1'" 'col2 = val2'
select 
  col1, col2 ..
from
  table_name
where col1 = 'val1' and col2 = val2;

You could invoke it without arguments too and it will generate valid SQL:

Code:
% ksh s                              
select 
  col1, col2 ..
from
  table_name
;
