[GitHub] [shardingsphere] Simbafa opened a new issue #6527: Mysql limit does not support variant
Simbafa opened a new issue #6527:
URL: https://github.com/apache/shardingsphere/issues/6527
## Bug Report
### Which version of ShardingSphere did you use?
The latest version: Shardingsphere-ui-4.1.1
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
limit/offset can use variants.
### Actual behavior
ERROR: Statement parameter 1 not set., SqlState: S1009, code:0
### Reason analyze (If you can)
I searched internet, someone says that Mysql does not support limit variant before 5.5 version.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
### Example codes for reproduce this issue (such as a github link).
```java
static void testLimit() throws Exception {
Class.forName("com.mysql.jdbc.Driver");
String url ="jdbc:mysql://192.168.1.46:3307/test?user=root&password=test&serverTimezone=UTC&useSSL=false&useServerPrepStmts=true";
//url = "jdbc:mysql://192.168.0.108:3306/test?user=root&password=test&zeroDateTimeBehavior=convertToNull&useServerPrepStmts=true";
//String user= java.util.Base64.getEncoder().encodeToString(url.getBytes("UTF-8"));
//url ="jdbc:mysql://192.168.1.46:3307/test?user="+user+"&password=test&useServerPrepStmts=true";
Connection conn = DriverManager.getConnection(url);
List<Object> params = new ArrayList<Object>();
params.add(20); params.add(0);
selectSql(conn, "select * from sys_migrate ", params, 0);
selectSql(conn, "select * from sys_migrate limit ? offset ?", params, 2);
}
static void selectSql(Connection conn, String sql, List<Object> paramValues, int paramValuesCount) throws SQLException {
PreparedStatement stmt = null;
try {
System.out.println("selectSql PREPARE: " + sql);
stmt = conn.prepareStatement(sql);
paramValuesCount = paramValues == null ? 0 : paramValuesCount;
for (int i = 0; i < paramValuesCount; i++) {
stmt.setObject(i + 1, paramValues.get(i));
}
ResultSet rs = stmt.executeQuery();
ResultSetMetaData rsmd = rs.getMetaData();
int count = rsmd.getColumnCount();
while (rs.next()) {
for (int i = 1; i <= count; i++) {
String key = rsmd.getColumnLabel(i);
Object value = rs.getObject(i);
System.out.println("key:" + key + ", value:" + (value==null?"null":value));
}
}
rs.close();
} catch (SQLException e) {
System.out.println("===Error:" + e.getMessage()+", SqlState: " + e.getSQLState() + ", code:" + e.getErrorCode());
} finally {
if (stmt != null) {
stmt.close();
}
}
}
```

[GitHub] [shardingsphere] Simbafa commented on issue #6527: Mysql limit does not support variant
Posted by GitBox <gi...@apache.org>.

URL: https://github.com/apache/shardingsphere/issues/6527#issuecomment-666340545
MySQLPacketCodecEngine.java is modified, because sometimes resetReaderIndex() is called.
But using the test code, it dosen't occur.
I just add "System.out.println()" in decode method
```
@Override
public void decode(final ChannelHandlerContext context, final ByteBuf in, final List<Object> out, final int readableBytes) {
int payloadLength = in.markReaderIndex().readMediumLE();
int realPacketLength = payloadLength + MySQLPacket.PAYLOAD_LENGTH + MySQLPacket.SEQUENCE_LENGTH;
if (readableBytes < realPacketLength) {
System.out.println("====================resetReaderIndex==============");
in.resetReaderIndex();
return;
}
out.add(in.readRetainedSlice(payloadLength + MySQLPacket.SEQUENCE_LENGTH));
}
```
When using 5.1.47, "java.sql.SQLException: Unknown system variable 'transaction_isolation'" is thrown.
```

Yes. I have tried:

"jdbc:mysql://127.0.0.1:3307/sharding_db?serverTimezone=UTC&useSSL=false&useServerPrepStmts=true"
