    Which of the Following is Not an ADO.Net Data Provider? - ProProfs

    Which of the Following is Not an ADO.Net Data Provider?

    • LINQ

    • Odbc

    • OleDB

    • SqlClient

    Correct Answer
    A. LINQ
    Explanation
    LINQ is not an ADO.Net Data Provider. LINQ (Language Integrated Query) is a query language that allows developers to query various data sources, including databases, collections, and XML. It is not a specific data provider like Odbc, OleDb, or SqlClient, which are used to connect and interact with specific types of databases. Therefore, LINQ is the correct answer as it is not a data provider.

    In ADO.Net, What Represents a Memory-Resident Set of Data that Includes Related Tables and its Relationship?

    • DataObjects

    • DataSet

    • DataTables

    • TableSet

    Correct Answer
    A. DataSet
    Explanation
    A DataSet in ADO.Net represents a memory-resident set of data that includes related tables and their relationships. It is a disconnected, in-memory representation of data that can hold multiple tables, relationships, and constraints. It allows for efficient data manipulation and provides a way to store and work with data from multiple sources or tables in a single object.

    What Does the DataType Field GUID Stand For? - ProProfs

    What Does the DataType Field GUID Stand For?

    • General Unique Identifier

    • Globally Unassigned Integer Data

    • Globally Unique Identifier

    Correct Answer
    A. Globally Unique Identifier
    Explanation
    The correct answer is "Globally Unique Identifier". A GUID is a unique value that is assigned to a data field in order to identify it globally. It is a 128-bit integer value that is generated by the computer system and is guaranteed to be unique across all devices and databases. GUIDs are commonly used in computer systems and databases to ensure the uniqueness of data records and to facilitate data synchronization and replication.

    • Added

    • Default

    • Detached

    • Unchanged

    Correct Answer
    A. Default
    Explanation
    The "Default" option is not a DataRowState field because DataRowState is an enumeration that represents the state of a DataRow object in a DataTable. The DataRowState enumeration includes values such as Added, Detached, and Unchanged, which indicate different states of a DataRow. However, there is no "Default" state defined in the DataRowState enumeration.

    IDataRecord is the correct answer because it is the interface that provides a DataReader access to the values of the column within each row. IDataRecord contains methods and properties that allow for the retrieval of column values based on their index or name, as well as the ability to check for null values. IDataRecord is commonly used in ADO.NET to read and manipulate data from a database.
