AutoDispose()

AutoDispose object and delegate from the cache after the code has been evaluated.

Example

-- SELECT 3
SELECT SQLNET::New('1+2').AutoDispose().EvalInt() as Result

Don’t worry, we have you covered! Object and Delegate are automatically disposed after a period of time without activity.

Code(string code)

Sets the code or expression to evaluate.

DECLARE @sqlnet SQLNET = SQLNET::New(‘’)

Example

DECLARE @sqlnet SQLNET = SQLNET::New('')

-- SELECT 3
SELECT @sqlnet.Code('1+2').EvalInt() as Result

Dispose()

Dispose object and delegate from the cache

Example

DECLARE @sqlnet SQLNET = SQLNET::New('x + y')

SELECT @sqlnet
.ValueInt('x', 1)
.ValueInt('y', 2)
.EvalInt() as Result


SELECT @sqlnet.getcode() as Result

DECLARE @dispose BIT = @sqlnet.Dispose()

--Not work because dipose...
SELECT @sqlnet
.ValueInt('x', 1)
.ValueInt('y', 2)
.EvalInt() as Result


--Not work because dipose...
SELECT @sqlnet.getcode() as Result

Don’t worry, we have you covered! Object and Delegate are automatically disposed after a period of time without activity.

Impersonate()

Change the security context to impersonate the credential of the one who runs the T-SQL statements.

Example

-- REQUIRE EXTERNAL_ACCESS permission
DECLARE @sqlnet SQLNET = SQLNET::New('
string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

var dir = new DirectoryInfo(path);
return dir.GetFiles("*.*").Select(x => x.FullName).OrderBy(x => x).ToList();')
.Impersonate()

-- SELECT * FROM DesktopFiles ORDER BY File.Fullname
EXEC dbo.SQLNET_EvalResultSet @sqlnet

Impersonate the current execution context under which the routine is executing.

Root()

Root is required when the expression already specified value. This feature has been added to allow Parallelism.

Example

DECLARE @sqlnet SQLNET = SQLNET::New('x+y').ValueInt('y', 2).Root()

-- SELECT 3
SELECT @sqlnet.ValueInt('x', 1).EvalInt() as Result
