Hi list:
I'm using WebObjects 5.2.3 on Mac OS X 10.3.9 and the database MSSQL
Server 2000 on a Windows NT Machine.
I get the next exception when I try to update a row:
Error: com.webobjects.eoaccess.EOGeneralAdaptorException:
updateValuesInRowDescribedByQualifier --
com.webobjects.jdbcadaptor.JDBCChannel method failed to update row in
database
Reason: updateValuesInRowDescribedByQualifier --
com.webobjects.jdbcadaptor.JDBCChannel method failed to update row in
database

The code that throws the exception:
EOEditingContext ec = new EOEditingContext();
EOFetchSpecification fs = new EOFetchSpecification("Articulo",
null, null, true, false, null);
fs.setRefreshesRefetchedObjects(true);
fs.setFetchLimit(1);
Articulo articulo = (Articulo)
ec.objectsWithFetchSpecification(fs).lastObject();
articulo.setTipo("Luminaria");
ec.saveChanges();
and the SQL generated:
"UPDATE dbo.Art SET Tipo = ? WHERE Articulo = ?" withBindings:
1:"Luminaria"(tipo), 2:"1N-748-T"(articulo)
My model looks like this:
{
attributes = (
{
columnName = Accesorios;
externalType = bit;
name = accesorios;
precision = 1;
valueClassName = NSNumber;
valueType = i;
},
{
columnName = Articulo;
externalType = char;
name = articulo;
valueClassName = NSString;
valueType = c;
width = 20;
},
{
columnName = Conciliar;
externalType = bit;
name = conciliar;
precision = 1;
valueClassName = NSNumber;
valueType = i;
},
{
columnName = Estatus;
externalType = char;
name = estatus;
valueClassName = NSString;
valueType = c;
width = 15;
},
{
columnName = Impuesto1;
externalType = float;
name = impuesto1;
precision = 53;
valueClassName = NSNumber;
valueType = f;
},
{
columnName = MonedaCosto;
externalType = char;
name = monedacosto;
valueClassName = NSString;
valueType = c;
width = 10;
},
{
columnName = MonedaPrecio;
externalType = char;
name = monedaprecio;
valueClassName = NSString;
valueType = c;
width = 10;
},
{
columnName = ProdOpciones;
externalType = bit;
name = prodopciones;
precision = 1;
valueClassName = NSNumber;
valueType = i;
},
{
columnName = Refacciones;
externalType = bit;
name = refacciones;
precision = 1;
valueClassName = NSNumber;
valueType = i;
},
{
columnName = Refrigeracion;
externalType = bit;
name = refrigeracion;
precision = 1;
valueClassName = NSNumber;
valueType = i;
},
{
columnName = SeProduce;
externalType = bit;
name = seproduce;
precision = 1;
valueClassName = NSNumber;
valueType = i;
},
{
columnName = Sustitutos;
externalType = bit;
name = sustitutos;
precision = 1;
valueClassName = NSNumber;
valueType = i;
},
{
columnName = TieneCaducidad;
externalType = bit;
name = tienecaducidad;
precision = 1;
valueClassName = NSNumber;
valueType = i;
},
{
columnName = Tipo;
externalType = varchar;
name = tipo;
valueClassName = NSString;
valueType = S;
width = 20;
},
{
columnName = TipoOpcion;
externalType = varchar;
name = tipoopcion;
valueClassName = NSString;
valueType = S;
width = 20;
}
);
attributesUsedForLocking = (articulo);
className = Articulo;
classProperties = (
impuesto1,
tipo,
tipoopcion,
accesorios,
refacciones,
sustitutos,
monedacosto,
monedaprecio,
estatus,
conciliar,
refrigeracion,
tienecaducidad,
seproduce,
prodopciones
);
externalName = "dbo.Art";
fetchSpecificationDictionary = {};
name = Articulo;
primaryKeyAttributes = (articulo);
}
As you can see I'm locking on a String with value type c, I'm not sure
what the problem is and how to fix it, please somebody help me, I'll
appreciate your help.
