-------------------------------------
{code:java}
JdbcSchema
// code placeholder
switch (SqlType.valueOf(dataType)) {
case TIMESTAMP:
case TIME:
precision = resultSet.getInt(9); // SCALE
scale = 0;
break;
default:
precision = resultSet.getInt(7); // SIZE
scale = resultSet.getInt(9); // SCALE
break;
} {code}
it seems that the datetime of mysql is mapped to the timestamp(0) type of
jdbc/calcite，Not sure if it's the problem here

> When I have a mysql table, the example is as follows:

> |1|2021-08-11 14:38:01.0|1|
>
> it will be OK:
> {{select gettime from table}}
>
> it will occor some error:
> {{select substring_index(cast(gettime as varchar),'.',1) from table}}
