ZhangCheng created NIFI-7410:
--------------------------------
Summary: Clob unreadable code when convertToAvroStream in
JdbcCommon.java
Key: NIFI-7410
URL: https://issues.apache.org/jira/browse/NIFI-7410
Project: Apache NiFi
Issue Type: Bug
Reporter: ZhangCheng
when ExecuteSql or QueryDataBaseTable processor trigger below code in
JdbcCommon.java ,clob would be unreadable code（with Chinese character）
{code:java}
if (javaSqlType == CLOB) {
Clob clob = rs.getClob(i);
if (clob != null) {
long numChars = clob.length();
char[] buffer = new char[(int) numChars];
InputStream is = clob.getAsciiStream();
int index = 0;
int c = is.read();
while (c >= 0) {
buffer[index++] = (char) c;
c = is.read();
}
rec.put(i - 1, new String(buffer));
clob.free();
} else {
rec.put(i - 1, null);
}
continue;
}
{code}
I konw this can be resoveld by using ExecuteSqlRecord and
QueryDatabaseTableRecord.
But I think this should be maintained too.
