hsqldb procedure with date Input parameter - mysql

Question

I need to write a test for some download operation. This operation call procedure from MSSQL database, take result set and java make some stuf. For test I use hsqldb.
My procedure:
CREATE PROCEDURE map.Get1(IN packageName varchar(100),
IN downloadDate DATE)
READS SQL DATA DYNAMIC RESULT SETS 1 BEGIN ATOMIC
DECLARE result CURSOR WITH RETURN FOR SELECT * FROM map.tvschedule FOR READ ONLY;
OPEN result;
END
This procedure wan't work, i have an exception
call map.GET1('Genre','2018-03-10');
[42561][-5561] incompatible data type in conversion
java.lang.RuntimeException: org.hsqldb.HsqlException: incompatible data type
in conversion
But this(without date parameter) work well:
CREATE PROCEDURE map.Get1(IN packageName varchar(100))
READS SQL DATA DYNAMIC RESULT SETS 1 BEGIN ATOMIC
DECLARE result CURSOR WITH RETURN FOR SELECT * FROM map.tvschedule FOR READ ONLY;
OPEN result;
END
call map.GET1('Genre');
first needed row
second needed row
I am not going to use input parameter, but i need this procedure to be looking i am going to.
My question is How to use date input parameter with hsqldb procedures?
UPDATE1:
I used TO_DATE and now it works well, but i have no data in my result set, my java code is:
try (CallableStatement callableStatement = connection.prepareCall("{ call
map.GetGenreProtocol( ?, ? ) }")) {
callableStatement.setString(1, packageName);
callableStatement.setDate(2, date);
callableStatement.execute();
ResultSet resultSet = callableStatement.getResultSet();
while (resultSet.next()) {
Interval Interval = new Interval();
Interval.setDuration(resultSet.getInt("duration"));
Interval.setMappingTargetId(resultSet.getInt("mappingTargetId"));
Interval.setGenreId(resultSet.getInt("genreId"));
Interval.setStart(resultSet.getLong("start"));
Interval.setCategoryId(resultSet.getInt("categoryId"));
Interval.setCategoryName(resultSet.getString("categoryName"));
Interval.setGenreName(resultSet.getString("genreName"));
Interval.setDescription(resultSet.getString("description"));
Intervals.add(Interval);
}
}

Answer 1

Use the TO_DATE function.
For example:
call map.GET1('Genre', TO_DATE('2018-03-10', 'YYYY-MM-DD'));
I guess you need to create a function that returns a table instead of a procedure:
CREATE FUNCTION map.Get1(IN packageName VARCHAR(100),
IN downloadDate DATE)
RETURNS TABLE(.....)
READS SQL DATA
BEGIN ATOMIC
....
END;
