SqlContext Class

Represents an abstraction of the caller's context, which provides access to the SqlPipe, SqlTriggerContext, and WindowsIdentity objects. This class cannot be inherited.

Namespace: Microsoft.SqlServer.Server
Assembly: System.Data (in

public sealed class SqlContext
public final class SqlContext
public final class SqlContext
Not applicable.

The SqlContext object can be used to obtain the trigger context (for code executing in a trigger) and the pipe object (when available, such as in stored procedures). It can also be used to obtain a WindowsIdentity object that represents the Microsoft Windows identity of the calling client, if the client authenticated with the server using integrated authentication.

The following example creates a new SqlDataRecord and its SqlMetaData. The example then marks the beginning of a result set using the SendResultsStart method, sends records with example data back to the client using the SendResultsRow method, and marks the end of the result set with the SendResultsEnd method.

public static void StoredProcReturnResultSet()
    // Create the record and specify the metadata for the columns.
    SqlDataRecord record = new SqlDataRecord(
        new SqlMetaData("col1", SqlDbType.NVarChar, 100),
        new SqlMetaData("col2", SqlDbType.Int));

    // Mark the begining of the result-set.

    // Send 10 rows back to the client.
    for (int i = 0; i < 10; i++)
        // Set values for each column in the row.
        record.SetString(0, "row " + i.ToString());
        record.SetInt32(1, i);

        // Send the row back to the client.

    // Mark the end of the result-set.
