在Java中,可以通过以下步骤将CLOB类型转换为String:
Clob clob = resultSet.getClob("clob_column");
Reader reader = clob.getCharacterStream();
StringBuilder stringBuilder = new StringBuilder();
char[] buffer = new char[1024];
int bytesRead = 0;
while ((bytesRead = reader.read(buffer)) != -1) {
stringBuilder.append(buffer, 0, bytesRead);
}
String clobString = stringBuilder.toString();
