Comentarios

The SMO enumeration URN contains four parts. First is the string, RuntimeServer" followed by a connection. The following line of code shows an EnumURN property where a connection has been specified.

RuntimeServer[@Connection='{B1552E8D-43AE-44B1-B5D3-03C4F5461977}']/Server[@Name='localhost']/SMOEnumObj[@Name='Databases']/SMOEnumType[@Name='Names']

The second part of the string is the server name parameter.

The last two parts are the SMOEnumObj and SMOEnumType parameters. The third part, the SMOEnumObj parameter, names the enumeration object that is enumerated. Valid values are:

@"LinkedServers"

@"Jobs"

@"Logins"

@"Databases"

@"FileGroups"

@"DataFiles"

@"LogFiles"

@"StoredProcedures"

@"UserDefinedDataTypes"

@"UserDefinedFunctions"

@"Views"

@"Users"

@"Tables"

@"Columns"

@"ForeignKeys"

@"Triggers

The code sample above shows an enumeration over databases.

The fourth part, the SMOEnumType parameter, specifies which enumeration type should be used. Valid values are:

@"Objects"

@"ObjectsPP"

@"Names"

@"URNs"

@"Locations"

The code sample above shows an enumeration using names.

Ejemplos

The following code example shows the construction of an EnumURN property.

Package package = new Package();
ForEachLoop loop = (ForEachLoop)package.Executables.Add("STOCK:FOREACHLOOP");
loop.Name = "ForEachLoop";

// Create Enumerator Info.
ForEachEnumeratorInfos infos = app.ForEachEnumeratorInfos;
ForEachEnumeratorInfo info = infos[EnumType.SMOEnum];
if (info == null)
    throw new ApplicationException("Could not find ForEachEnum for: 
        "+EnumType.SMOEnum);

// Create Enumerator.
ForEachEnumeratorHost enumW = info.CreateNew();
if (enumW == null)
    throw new ApplicationException("null enumerator was created");

ForEachSMOEnumerator smoEnumerator = (ForEachSMOEnumerator)enumW.InnerObject;
enumerator.EnumURN = RuntimeServer[@Connection='{B1552E8D-43AE-44B1-B5D3-03C4F5461977}']/Server[@Name='localhost']/SMOEnumObj[@Name='Databases']/SMOEnumType[@Name='Names']
