An object that can be used to get information about the types and properties for each parameter marker in a PreparedStatement object.

[Android.Runtime.Register("java/sql/ParameterMetaData", "", "Java.Sql.IParameterMetaDataInvoker")]
public interface IParameterMetaData : IDisposable, Java.Interop.IJavaPeerable, Java.Sql.IWrapper

[<Android.Runtime.Register("java/sql/ParameterMetaData", "", "Java.Sql.IParameterMetaDataInvoker")>]
type IParameterMetaData = interface
    interface IWrapper
    interface IJavaObject
    interface IDisposable
    interface IJavaPeerable

Attributes: RegisterAttribute

Implements: IJavaObject IJavaPeerable IWrapper IDisposable

Remarks

An object that can be used to get information about the types and properties for each parameter marker in a PreparedStatement object. For some queries and driver implementations, the data that would be returned by a ParameterMetaData object may not be available until the PreparedStatement has been executed.

Some driver implementations may not be able to provide information about the types and properties for each parameter marker in a CallableStatement object.

Fields

ParameterModeIn	The constant indicating that the parameter's mode is IN.
ParameterModeInOut	The constant indicating that the parameter's mode is INOUT.
ParameterModeOut	The constant indicating that the parameter's mode is OUT.
ParameterModeUnknown	The constant indicating that the mode of the parameter is unknown.
ParameterNoNulls	The constant indicating that a parameter will not allow `NULL` values.
ParameterNullable	The constant indicating that a parameter will allow `NULL` values.
ParameterNullableUnknown	The constant indicating that the nullability of a parameter is unknown.

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
JniIdentityHashCode	Returns the value of `java.lang.System.identityHashCode()` for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
ParameterCount	Gets the number of parameters in the `PreparedStatement` for which this `ParameterMetaData` contains information.
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
GetParameterClassName(Int32)	Retrieves the fully-qualified name of the Java class whose instances should be passed to the method `PreparedStatement.setObject`.
GetParameterMode(Int32)	Retrieves the designated parameter's mode.
GetParameterType(Int32)	Retrieves the designated parameter's SQL type.
GetParameterTypeName(Int32)	Retrieves the designated parameter's database-specific type name.
GetPrecision(Int32)	Retrieves the designated parameter's specified column size.
GetScale(Int32)	Retrieves the designated parameter's number of digits to right of the decimal point.
IsNullable(Int32)	Retrieves whether null values are allowed in the designated parameter.
IsSigned(Int32)	Retrieves whether values for the designated parameter can be signed numbers.
IsWrapperFor(Class)	Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. (Inherited from IWrapper)
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)
Unwrap(Class)	Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. (Inherited from IWrapper)

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
JavaCast<TResult>(IJavaObject)
GetJniTypeName(IJavaPeerable)
