i have created MySQL stored procedure for the update query.
delimiter //
create procedure studentrcs(sname varchar(20),smark1 int(3),smark2 int(3),stotal int(10),inout Regno int(6))
begin
UPDATE studentrecords set student_name=sname,mark1=smark1,mark2=smark2,total=stotal where Reg_no=Regno;
end;//
After that, through callable statement how i can pass value(at run time) as parameter
CallableStatement calstat=null;
calstat=conn.prepareCall("{call studentrcs(?,?,?,?,?)}"); // **how i can pass the value here(at run time).**
//System.out.println("Update");
calstat.setString(1,tname.getText());
calstat.setString(2, treg.getText());
calstat.setString(3, tmark1.getText());
calstat.setString(4, tmark2.getText());
calstat.setString(5, ttotal.getText());
calstat.executeUpdate();
You have an INOUT parameter specified (Regno) in your stored procedure so you'll need to both specify a value for it's input and register it with the CallableStatement.registerOutParameter method. Also, try setting int values for your int input parameters too.
For example:
CallableStatement calstat=null;
calstat=conn.prepareCall("{call studentrcs(?,?,?,?,?)}"); // **how i can pass the value here(at run time).**
//System.out.println("Update");
calstat.setString(1,tname.getText());
calstat.setInt(2, Integer.parseInt(treg.getText()));
calstat.setInt(3, Integer.parseInt(tmark1.getText()));
calstat.setInt(4, Integer.parseInt(tmark2.getText()));
calstat.setInt(5, Integer.parseInt(ttotal.getText()));
calstat.registerOutParameter(5, Types.NUMERIC);
calstat.executeUpdate();
I'm assuming that all of this is in a try catch finally block so I have left out handling the NumberFormatException that will be raised if tmark1.getText(), tname.getText(), tmark2.getText() or ttotal.getText() return not valid integer values.
More info about calling MySQL routines from Java here
As an aside I don't know why you just don't just dump the SQL update method into it's own Java method and call that rather than creating a stored MySQL routine. Just my opinion though!

I have stored procedure with input parameter of type number.
CREATE OR REPLACE PROCEDURE my_procedure (p_x number)
AS
I included exception handling code as below, but that do not handle following:
execute my_procedure ('sads')
EXCEPTION
WHEN VALUE_ERROR THEN
DBMS_OUTPUT.PUT_LINE('SQLERRM: ' || SQLERRM);
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('SQLERRM: ' || SQLERRM);
is there any way to change exception for bad arguments?
The error will happen when the procedure is invoked, not inside of the procedure so you can't capture the error as an exception within that procedure itself. A possible solution would be use an additional procedure that validates the arguments. In the example code below the procedure so_arg_test.my_procedure accepts a VARCHAR2 but it will only invoke my_procedure_hidden if the argument actually is a number. For anything other it will raise a value error.
CREATE OR REPLACE PACKAGE so_arg_test AS
PROCEDURE my_procedure (
p_x IN VARCHAR2
);
END so_arg_test;
/
CREATE OR REPLACE
PACKAGE BODY SO_ARG_TEST AS
procedure my_procedure_hidden (p_x IN NUMBER) AS
BEGIN
-- your code
dbms_output.put_line('Inside my_procedure_hidden');
END my_procedure_hidden;
procedure my_procedure (p_x IN VARCHAR2)
AS
BEGIN
IF VALIDATE_CONVERSION(p_x AS NUMBER) = 0 THEN
RAISE VALUE_ERROR;
END IF;
my_procedure_hidden (p_x => my_procedure.p_x);
END my_procedure;
END SO_ARG_TEST;

I want to return a value from Stored Procedure which I can use in my Spring Boot server in JPA repository.
Here's my Stored Procedure,I want to know how do I return String from the Procedure.
DELIMITER //
CREATE PROCEDURE GetAllProducts(out query varchar(20))
BEGIN
SET query=SELECT title FROM course where description="just a course";
RETURN #query;
END //
DELIMITER ;
I am selecting 1 value from the query table to return it.
Can someone Help?
Thanks!
If you want to use your SP as datasource (like you execute SELECT, not CALL, in external program) you must select to output stream, not to variable:
CREATE PROCEDURE GetAllProducts()
SELECT title
FROM course
WHERE description="just a course";
Got the Solution,Its working now!
Just tweaked the Procedure a little bit:
DELIMITER //
CREATE PROCEDURE GetAllProdcuts(OUT output VARCHAR(50))
BEGIN
SELECT title into output
FROM course
WHERE description="just a course";
END //
Does r2dbc currently supports calling Stored proc in my sql with in/out parameters ?
I am trying to call Stored Proc using databaseClient which returns a String.But I am getting the below exception.Do I have to add anything to call SP from r2dbc.My stored procedure looks like this.How to call SP using database-client
CREATE PROCEDURE usp_get_data(in someId varchar(255),
in someName varchar(255),
out email varchar(255))
BEGIN
SELECT email FROM products where id=:someId and name=:someName LIMIT 1;
END //
Below is my code.
String STORED_PROC = "call usp_get_data(:someId,:someName)"
def result = databaseClient.execute(STORED_PROC)
.bindNull("someId","someId")
.bindNull("someName", "someName")
.as(String.class)
.fetch().one()
Incorrect number of arguments for PROCEDURE usp_get_data expected 3, got 2))
Forgot to add #out in the call stored procedure statement.
modifying my execution below worked.
String STORED_PROC = "call usp_get_data(:someId,:someName,#email);
Select #email"
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);
}
}
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;
I have two procedure namely "createOrder" And "createAndress"
And in "createOrder" procedure i have 4 IN parameter and 1 out parameter.
And in "createAndress" procedure i have 3 IN parameter and 1 out parameter.
And i am calling "createAndress" inside the "createOrder" procedure like below
CALL create_address (in_userprofile_id, in_pin, true, in_address_id);
but how to get out value of "createAndress" into "createOrder" procedure ?
Do this inside your CreateOrder stored proc
-- Declare the variable to receive the output value of the procedure.
DECLARE #OutParameterForCreateAddress INT;
-- Execute the procedure specifying in_userprofile_id, in_pin, true,in_address_id for the input parameter
-- and saving the output value in the variable #OutParameterForCreateAddress
EXECUTE create_address in_userprofile_id, in_pin, true, in_address_id, #YourOutParameterNameinCreatedAddress = #OutParameterForCreateAddress OUTPUT;
-- Display the value returned by the procedure.
Print #OutParameterForCreateAddress
