org.apache.flink.table.api.ValidationException: Could not find an
implementation method 'eval' in class
'org.apache.flink.table.runtime.functions.scalar.ConvFunction' for function
'CONV' that matches the following signature:
org.apache.flink.table.data.StringData
eval(org.apache.flink.table.data.StringData, java.lang.Byte, java.lang.Integer)

// code placeholder
public class ConvFunction extends BuiltInScalarFunction {

// the names of the function input and r differ
tEnv().executeSql("INSERT INTO TestTable select conv(3, cast(1 AS TINYINT),
4)").await();
