BOF o EOF es True

[fercom]

holal "asperos", espero todos esten bien.

les comento mi duda. tengo una pagina asp que da resultados de busqueda. pero cuando no encuentra algun registro en la BD SQL me da este error

Tipo de error:
ADODB.Field (0x800A0BCD)
El valor de BOF o EOF es True, o el actual registro se eliminó; la operación solicitada requiere un registro actual.
/capacitacion/Notas/notas1.asp, línea 397

lo que quiero hacer es que cuando exista resultados de busqueda en la BD salgan los resultados pero si no hay resultados en ves de que salga esta pagina de error salga un mensaje que diga no se encontraron registros en su busqueda.

si alguien quiere le puedo mandar el archivo asp por mail mandar su mail

[u_goldman]

Condiciónalo...con la propiedad EOF(End Of FIle) si no es fin de archivo muestras los registros, de lo contrario, mandas mensaje de que no se encontraron coincidencias.

If NOT rs.EOF Then
'Muestra registros
Then
'IMprimes que no se encontraron resultados
End If

Salu2,

[S|ck]

if (rs.recordcount = 0) then
response.write ("lo k sea")

un favor me pueden decir en que parte del codigo pongo eso

[Myakire]

Open es normalmente, para ejecutar instrucciones SQL que regresan datos, Execute es para las que no regresan datos (Insert o Update) pero tambien es usado para Selects.

Saludos

[fercom]

ok voy a probar
cualquier cosa regresoo

1000 Graciasss!!!!!!!!!!!

[fercom]

Ahora me sale esto

Tipo de error:
Error de compilación de Microsoft VBScript (0x800A0400)
Se esperaba una instrucción
/capacitacion/Notas/notas1.asp, línea 111
Then

tu crees q lo puedes hacer añadiendolo a la pag q esta arriba. la pagina funciona bien solo que cuando no haya nada en BD sale eof o bof es true yo quier q en ves q salga eso salga no se encontraron registros.

gracias de antemano

[Myakire]

¿Puedes poner +-3 lineas de la 111?

[fercom]

Listo Myakire el error estaba en que then debe ser else y no me habia percatado.

Iniciado por Myakire

...
Registro_Notas.Open()
If NOT Registro_Notas.EOF Then

Then

End If

ahora si funciona de maravilla

GRACIAS A TODOS LOS QUE COLABORARON YA APRENDÎ ALGO NUEVO Y DE MUCHA UTILIDAD

PD DEBERIAN HACER UN POST DE TODAS LAS FUNCIONES QUE HAY PARA IF ELSE, es una idea!!!

[Myakire]

ok, pero ¿Post para IF-Then?

If <cond. booleana> Then
....
[Else]
...
End If

If <cond. booleana> Then
...
ElseIf <cond. booleana> Then
....<tantos como necesites>
[Else]

O mejor un Select.. Case
