updateCharacterStream Method (java.lang.String, java.io.Reader, int)
Updates the designated column with a character stream value, which will have the specified number of characters.
public void updateCharacterStream(java.lang.String columnName,
java.io.Reader readerValue,
int length)
Parameters
columnName
A String that contains the column name.
readerValue
A Reader object.
length
An int that indicates the length of the stream.
Exceptions
Remarks
This updateCharacterStream method is specified by the updateCharacterStream method in the java.sql.ResultSet interface.
This method passes Unicode characters from a Reader object to selected text and binary columns. This includes all text columns and binary, varbinary, varbinary(max), image, and xml columns, but not udt columns.
If the length of the stream is different than that specified in the length parameter, the JDBC driver throws an exception when the row is updated or inserted.
If the length of the stream is unknown, the length parameter may be set to -1 to indicate that the driver should accept the stream regardless of its length. With sqljdbc4.jar, we recommend that you use the JDBC 4.0 method updateCharacterStream Method (java.lang.String, java.io.Reader) when the application wants to update the column from a stream whose length is unknown.
