SetNull(Int32, Int32, String)

Sets the designated parameter to SQL NULL.

[Android.Runtime.Register("setNull", "(IILjava/lang/String;)V", "GetSetNull_IILjava_lang_String_Handler:Java.Sql.IPreparedStatementInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")]
public void SetNull (int parameterIndex, int sqlType, string? typeName);

abstract member SetNull : int * int * string -> unit

Parameters

parameterIndex

Int32

the first parameter is 1, the second is 2, ...

sqlType

Int32

a value from java.sql.Types

typeName

String

the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF

Attributes

RegisterAttribute

Exceptions

SQLException

if a database error happens.

Remarks

Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

<B>Note:</B> To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it.

Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.
