Oracle 大文本Clob类型字段插入失败ORA-22275: invalid LOB locator specified
读取出来的字段属性为Clob类型,转换为String类型,再操作就可以了。
import java.sql.Clob;
import java.io.BufferedReader;
import java.io.Reader;
public static String clobToStr(Clob clob) throws Exception{
Reader is = clob.getCharacterStream();
BufferedReader br = new BufferedReader(is);
String line = br.readLine();
StringBuffer sb = new StringBuffer();
while (line != null) {
sb.append(s);
line = br.readLine();
}
if(br!=null){
br.close();
}
if(is!=null){
is.close();
}
return sb.toString();
}
