mysql stored procedure multiple parameters

I am trying to add multiple dynamic columns in the select statement, (stored procedure) But it's not working at my end, Can you please help me on same.
BEGIN SET #col1 = col1;SET #col1 = col2;SET #getID = CONCAT('SELECT ' ,#col1 = col1, #col2 = col2,' FROM',tablename_In,' WHERE `type`= type ORDER BY id DESC LIMIT ?,?'); PREPARE stmt FROM #getID;SET #START =_START; SET #LIMIT = _LIMIT;EXECUTE stmt USING #START, #LIMIT; DEALLOCATE PREPARE stmt; END
Also, I have another stored procedure it's also not working with between query:
BEGIN SET #getID = CONCAT('SELECT count(id) as co FROM ',tablename_In,' WHERE',est_time,' BETWEEN',start_date,'AND',end_date);PREPARE stmt FROM #getID; EXECUTE stmt; DEALLOCATE PREPARE stmt; END

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

Insert query on procedure

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

Correct code improvement

Can somebody look at my code ,because I dont know if its OK or no in MySQL
set #max=concat('select max(length(CommentsId))from', table_name);
prepare stmt from #max;
execute stmt;
set #max=concat('UPDATE', table_name, 'SET CommentsId= ',CommentsId * power(10, (#max - length(CommentsId))),' WHERE CommentsId= ', #CommentsId );
prepare stmt from #max;
execute stmt;

You need spaces before or after your from, UPDATE, and SET keywords.
set #max=concat('select max(length(CommentsId)) from ', table_name);
prepare stmt from #max;
execute stmt;
set #max=concat('UPDATE ', table_name, ' SET CommentsId= ',CommentsId * power(10, (#max - length(CommentsId))),' WHERE CommentsId= ', #CommentsId );
prepare stmt from #max;
execute stmt;
