  • Reference

Definition

Namespace:
Java.Sql
Assembly:
Mono.Android.dll

Overloads

SetCharacterStream(Int32, Reader)

Sets the designated parameter to the given Reader object.
SetCharacterStream(Int32, Reader, Int32)

Sets the designated parameter to the given Reader object, which is the given number of characters long.
SetCharacterStream(Int32, Reader, Int64)

Sets the designated parameter to the given Reader object, which is the given number of characters long.

SetCharacterStream(Int32, Reader)

Sets the designated parameter to the given Reader object.

[Android.Runtime.Register("setCharacterStream", "(ILjava/io/Reader;)V", "GetSetCharacterStream_ILjava_io_Reader_Handler:Java.Sql.IPreparedStatementInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")]
public void SetCharacterStream (int parameterIndex, Java.IO.Reader? reader);
[<Android.Runtime.Register("setCharacterStream", "(ILjava/io/Reader;)V", "GetSetCharacterStream_ILjava_io_Reader_Handler:Java.Sql.IPreparedStatementInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")>]
abstract member SetCharacterStream : int * Java.IO.Reader -> unit

Parameters

parameterIndex
Int32

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

reader
Reader

the java.io.Reader object that contains the Unicode data

Attributes
RegisterAttribute

Exceptions

SQLException

if a database error happens.

Remarks

Sets the designated parameter to the given Reader object. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.Reader object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

<B>Note:</B> This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

<B>Note:</B> Consult your JDBC driver documentation to determine if it might be more efficient to use a version of setCharacterStream which takes a length parameter.
