Insert query on procedure - mysql

I have a procedure like this
set #dt=now();
SET #query = CONCAT('insert into tbl_Name (Name , Created_Date , Created_By) values (?,?,?)');
PREPARE stmt FROM #sql;
EXECUTE stmt using #tbl_column_value, #dt, #tbl_user_id;
END IF;
DEALLOCATE PREPARE stmt;
im getting this error
java.sql.SQLException: Incorrect arguments to EXECUTE

why does the in paratemers can not be used in PREPARE statement

I am studying mysql. Here is my code of practicing stored procedure.
CREATE DEFINER=`raxuser`#`%` PROCEDURE `test`(in fc_frm_date char(5), in fc_to_date char(5))
BEGIN
declare frm_date char(5);
declare to_date char(5);
select fc_frm_date into #frm_date;
select fc_to_date into #to_date;
select distinct #frm_date, #to_date, fc_frm_date, fc_to_date;
set #s = CONCAT('select distinct #frm_date, #to_date, fc_frm_date, fc_to_date;');
PREPARE stmt FROM #s; EXECUTE stmt; DEALLOCATE PREPARE stmt;
END
When I run it , the first select query get correct while the second one shows error code as
Error Code: 1054 Unknown column 'fc_frm_date' in 'field list'
I thought the two select queries should be equal but not. Can anyone help to explain?
Many thanks.

I think the right way to do this (UNTESTED) is:
set #s = CONCAT('select distinct ? , ? , ? , ?;');
PREPARE stmt FROM #s;
EXECUTE stmt USING #frm_date, #to_date, fc_frm_date, fc_to_date;
DEALLOCATE PREPARE stmt;

Try it:
CREATE DEFINER=`raxuser`#`%` PROCEDURE `test`(fc_frm_date char(5), fc_to_date char(5))
BEGIN
DECLARE frm_date CHAR(5);
DECLARE to_date CHAR(5);
SELECT fc_frm_date INTO #frm_date;
SELECT fc_to_date INTO #to_date;
SELECT fc_frm_date INTO #fc_frm_date;
SELECT fc_to_date INTO #fc_to_date;
SET #s = 'select distinct #frm_date, #to_date, #fc_frm_date, #fc_to_date';
PREPARE stmt FROM #s; EXECUTE stmt; DEALLOCATE PREPARE stmt;
SELECT #s;
END

SUBSTRING_INDEX and MySQL Stored Procedures

I am finding it hard to get a MySQL stored procedure to work when I use the SUBSTRING_INDEX and MID and LOCATE functions. The first Select I have works, the other 2 do not. Any help in getting this to work would be awesome.
CREATE DEFINER=`root`#`localhost` PROCEDURE `Address`(TBL VARCHAR(50))
BEGIN
SET #table_name = TBL;
SELECT CONCAT("UPDATE kalo.",#table_name,' SET AD1 = REPLACE(AD1,"."," ")') INTO #SQL;
PREPARE stmt FROM #SQL;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SELECT CONCAT("UPDATE kalo.",#table_name,' SET STNO = SUBSTRING_INDEX(AD1, ' ', +1)') INTO #SQL;
PREPARE stmt FROM #SQL;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SELECT CONCAT("UPDATE kalo.",#table_name,' SET STNM = MID(AD1, LOCATE(' ', AD1) + 1)') INTO #SQL;
PREPARE stmt FROM #SQL;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END

mysql prepared statment giving error

i am trying to write a stored procedure which updates the field of a table as specified in the argument .i am getting syntax error in #sql statment.please help
create procedure new_upd1(ind int(3),attribute varchar(30),pk int(11),new_value varchar(30))
begin
set #att=attribute;
set #primk=pk;
set #updated=new_value;
if ind=1 then
set #sql='update department set ?=? where departmentid=?';
prepare stmt from #sql;
execute stmt using #att,#updated,#primk;
deallocate prepare stmt;
end if;
end

Parameters don't work for column or table names, only for values. Do it like this:
create procedure new_upd1(ind int(3),attribute varchar(30),pk int(11),new_value varchar(30))
begin
set #att=attribute;
set #primk=pk;
set #updated=new_value;
if ind=1 then
set #sql=CONCAT('update department set ', #att, '=? where departmentid=?;');
prepare stmt from #sql;
execute stmt using #updated,#primk;
deallocate prepare stmt;
end if;
end

MySQL stored procedure return variable values from seconds query?

SET #v1 = '';
SET #v2 = '';
SET #Query = CONCAT('SELECT sum(colName1), sum(colName2) INTO #v1, #v2 FROM tableName WHERE id=1 ');
PREPARE stmt FROM #Query;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET #Query = CONCAT('SELECT id, name,',#v1,' as value1, ',#v2,' as value2 FROM tableName WHERE id=1 ');
PREPARE stmt FROM #Query;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
While reading values the throw an Exception - Column 'value1' does not belong to table.
How can I get the value of #v1 and #v2.
Please help me.

The #v2 has null value that why the stored procedure gives error.
