Stored Procedures

Stored procedure support is available through db.Procedures when DynamicDatabaseOptions.SupportStoredProcedures is enabled.

Basic Invocation

var scalar = db.Procedures.sp_Exp_Scalar();
var scalarTyped = db.Procedures.sp_Exp_Scalar<int>();

Input, Output, Return Parameters

Prefixes in argument names control parameter direction:

• out_ for output
• ret_ for return value
• both_ for input/output

Example pattern:

var res = db.Procedures.sp_Exp_SomeInputAndOutput<
    string,
    MyProcResult>(
        Name: "G4g4r1n",
        out_Result: new DynamicSchemaColumn { Size = 256 },
        ret_Return: 0);

Nested Procedure Names

Dynamic member chaining builds qualified names:

var res = db.Procedures.dbo.reporting.MyProc();

This resolves to dbo.reporting.MyProc.

Result Mapping

If generic return types are provided, DynamORM attempts mapper-based projection into the target type.

If output parameters are present, result payload is assembled from:

• main scalar/resultset-derived value
• output values
• optional return value

The behavior is implemented in DynamORM/DynamicProcedureInvoker.cs and documented in XML examples in DynamORM/DynamicDatabase.cs.
