  • QueryParameterMode Enum

    The enumeration describes how connection providers initialize command parameters.

    Namespace: DevExpress.Xpo.DB

    Assembly: DevExpress.Data.v25.1.dll

    NuGet Package: DevExpress.Data

    Declaration

    public enum QueryParameterMode

    Members

    Name Description Comments
    Default

    When Always Encrypted is enabled, the default behavior is the same as SetTypeAndSize, otherwise, providers work in SetType mode.

    Legacy

    A connection provider leaves the DbType, Precision, Scale, and Size properties unassigned.

    For backward compatibility only.

    SetType

    A connection provider initializes only the DbType property.

    This mode is optimal for most applications.

    SetTypeAndSize

    A connection provider initializes the DbType, Precision, Scale, and Size properties.

    Use this mode to support the Always Encrypted feature.
