IResultSet.GetUnicodeStream Method

Definition

Overloads

GetUnicodeStream(Int32)
Obsolete.

Retrieves the value of the designated column in the current row of this ResultSet object as as a stream of two-byte 3 characters.

GetUnicodeStream(String)
Obsolete.

Retrieves the value of the designated column in the current row of this ResultSet object as a stream of two-byte Unicode characters.

GetUnicodeStream(Int32)

Caution

deprecated

Retrieves the value of the designated column in the current row of this ResultSet object as as a stream of two-byte 3 characters.

[Android.Runtime.Register("getUnicodeStream", "(I)Ljava/io/InputStream;", "GetGetUnicodeStream_IHandler:Java.Sql.IResultSetInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")]
[System.Obsolete("deprecated")]
public System.IO.Stream? GetUnicodeStream (int columnIndex);
[<Android.Runtime.Register("getUnicodeStream", "(I)Ljava/io/InputStream;", "GetGetUnicodeStream_IHandler:Java.Sql.IResultSetInvoker, Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null")>]
[<System.Obsolete("deprecated")>]
abstract member GetUnicodeStream : int -> System.IO.Stream

Parameters

columnIndex
Int32

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

Returns

a Java input stream that delivers the database column value as a stream of two-byte Unicode characters; if the value is SQL NULL, the value returned is null

Attributes

Exceptions

if a database error happens.

Remarks

Retrieves the value of the designated column in the current row of this ResultSet object as as a stream of two-byte 3 characters. The first byte is the high byte; the second byte is the low byte.

The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHARvalues. The JDBC driver will do any necessary conversion from the database format into Unicode.

<B>Note:</B> All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.

This member is deprecated. use getCharacterStream in place of getUnicodeStream

Parameters

columnLabel
String

the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column

Returns

The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC technology-enabled driver will do any necessary conversion from the database format into Unicode.

<B>Note:</B> All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.
