Subject Re: [firebird-support] Index for query
Author Claudio Romero
You right
but I need this query with index

SELECT * FROM table where integer_field like '21095%'

because I use this in a function (Lazarus program) that support integer and
varchar fields.

Here the full function
function GeneraSentenciaSql(Tabla,FiltroFijo,filtro,valor:string):string;
var consulta:string;
begin
valor:=UpperCase(valor);
consulta:='select * from '+Tabla+' ';
if FiltroFijo<>'' then begin
consulta:=consulta+'where '+FiltroFijo+' ';
if (filtro<>'')and(valor<>'') then consulta:=consulta+'and
'+filtro+' like '+valor;
end
else if (filtro<>'')and(valor<>'') then consulta:=consulta+'where
'+filtro+' like '+valor;
if filtro<>'' then consulta:=consulta+' order by '+filtro;
//showmessage(consulta);
result:=consulta;
end;

Otherwise, I must include the data field as parameter of this funcion.
Regards
