I'm being passed in an optional OrderBy value that should default to DESC, and if set to false, should ORDER BY ASC. I'm not really sure how to do this ordering based off the input. Here is what I have currently:
CREATE DEFINER=`app`#`%` PROCEDURE `BLAH`(
pWithdrawalTransactionId INT,
pLimit INT,
pSortDescending TINYINT
)
BEGIN
DECLARE vLimit INT DEFAULT COALESCE(pLimit, 100);
DECLARE vSort TINYINT DEFAULT COALESCE(pSortDescending, 1);
SELECT
f.WithdrawalFulfillmentId, f.PaymentStatusId, f.PaymentProcessorId, f.PaymentTypeId, r.Amount, r.RequestedAmount, r.NativeAmount, r.NativeRequestedAmount, r.RefundTransactionId, r.UpdatedDate
FROM
FinOps.UserWithdrawalFulfillment f
INNER JOIN
FinOps.UserRefundTransaction r ON f.RefundTransactionId = r.RefundTransactionId
WHERE
f.WithdrawalTransactionId = pWithdrawalTransactionId
LIMIT
vLimit;
END
So the correct way to do this would be like this:
CREATE DEFINER=`app`#`%` PROCEDURE `BLAH`(
pWithdrawalTransactionId INT,
pLimit INT,
pSortDescending TINYINT
)
BEGIN
DECLARE vLimit INT DEFAULT COALESCE(pLimit, 100);
DECLARE vSort TINYINT DEFAULT COALESCE(pSortDescending, 1);
SELECT
f.WithdrawalFulfillmentId, f.PaymentStatusId, f.PaymentProcessorId, f.PaymentTypeId, r.Amount, r.RequestedAmount, r.NativeAmount, r.NativeRequestedAmount, r.RefundTransactionId, r.UpdatedDate
FROM
FinOps.UserWithdrawalFulfillment f
INNER JOIN
FinOps.UserRefundTransaction r ON f.RefundTransactionId = r.RefundTransactionId
WHERE
f.WithdrawalTransactionId = pWithdrawalTransactionId
ORDER BY CASE WHEN pSortDescending = 1 THEN WithdrawalFulfillmentId * -1 ELSE WithdrawalFulfillmentId END ASC
LIMIT
vLimit;
END

can anybody tell me how to implement a split function in mysql which behaves like Javascript split.
I want a function like this
SELECT Split('a,b,c,d', ',') AS splitted
Which give result like
splitted
--------------
a
b
c
d
Can anybody help me?
I saw some answers here, and somewhere else, but those functions need the position of string to be returned, which I don't want/have
Thank you
It is possible:
-- Preparation
CREATE TABLE tb_Digits (d int(11) UNSIGNED NOT NULL PRIMARY KEY);
INSERT tb_Digits VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9);
INSERT IGNORE tb_Digits
SELECT o1.d+o2.d*10+o3.d*100+o4.d*1000 d FROM tb_Digits o4, tb_Digits o3, tb_Digits o2, tb_Digits o1;
CREATE PROCEDURE pc_splitStr(IN in_string TEXT, IN in_separator CHAR(1))
COMMENT 'Use (SELECT word FROM return_splitStr) para ver o resultado'
BEGIN
DECLARE o_limit INT(11) UNSIGNED DEFAULT LENGTH(in_string)-LENGTH(REPLACE(in_string,in_separator,''))+1;
DROP TABLE IF EXISTS return_splitStr;
CREATE TEMPORARY TABLE return_splitStr (word TEXT);
INSERT return_splitStr
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(in_string, in_separator, d.d), in_separator, -1)
FROM tb_Digits d
WHERE d.d>0 AND d.d<=o_limit;
END;
-- Execution
CALL pc_splitStr('a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z',',');
SELECT word FROM return_splitStr;
You can create a function and return the specific result you are waiting for.
here is an example with multi ids in one column extracted and queried to get the specific values :
DROP FUNCTION IF EXISTS getValuesByOptionIds;
DELIMITER $$
CREATE FUNCTION getValuesByOptionIds
(
optionIds VARCHAR(255)
)
RETURNS VARCHAR(255)
DETERMINISTIC
BEGIN
DECLARE iter INTEGER DEFAULT 0;
DECLARE result VARCHAR(255) DEFAULT '';
DECLARE previousIter VARCHAR(255) DEFAULT '';
iters: WHILE LENGTH(SUBSTRING_INDEX(optionIds, ',', iter + 1)) != LENGTH(previousIter) DO
SET iter = iter + 1;
SET previousIter = SUBSTRING_INDEX(optionIds, ',', iter);
IF iter = 1 THEN
SET result = (select tmp.value from eav_attribute_option_value tmp where tmp.option_id = SUBSTRING_INDEX(optionIds, ',', iter));
ELSEIF iter > 1 THEN
SET result = concat(result, ',', (select tmp.value from eav_attribute_option_value tmp where tmp.option_id = SUBSTRING_INDEX(SUBSTRING_INDEX(optionIds, ',', iter), ',', -1)));
END IF;
END WHILE iters;
RETURN result;
END$$
DELIMITER ;

I really don't know why my function and view in phpmyadmin returns null instead of DATETIME.
This is my function:
DELIMITER $$
CREATE FUNCTION `return_file`( name varchar(10), number int )
RETURNS datetime
DETERMINISTIC
BEGIN DECLARE transdate DATETIME;
SET trans_date = (SELECT `date` from `sample_table` WHERE `name_ref` = name and `ref_number` = number and `type` = 10);
RETURN trans_date;
END$$
DELIMITER ;
While this is my view:
CREATE VIEW getsME as
SELECT id,type,date,name_ref,ref_number,return_file(name_ref,ref_number) as transDate
FROM sample_table
WHERE type= 11
ORDER BY id ASC
My question is kind of hard to explain in title so I'll show the data and goal.
There is a MySQL table with following structure:
CREATE TABLE customerProjectData(
idCustomer INT NOT NULL,
idProject INT DEFAULT NULL,
comePersons SMALLINT DEFAULT NULL,
comePairs SMALLINT DEFAULT NULL,
comment VARCHAR(255) DEFAULT NULL,
idCity INT DEFAULT NULL,
idStreet INT DEFAULT NULL,
name VARCHAR(64) DEFAULT NULL,
surname VARCHAR(64) DEFAULT NULL,
homeNum VARCHAR(10) DEFAULT NULL,
postCode CHAR(6) DEFAULT NULL,
postCity VARCHAR(64) DEFAULT NULL,
cellPhone VARCHAR(12) DEFAULT NULL
)
The thing is, there shold be also PRIMARY KEY(idCustomer, idProject) defined and it's not. As a result There are kind of duplicates (with the same primary key) but with different data.
I could run ALTER IGNORE TABLE but data loss would probably be unacceptable and unpredicatable. Finally we decided to try to fill null fields with values from duplicates if they contain data and after that run the ALTER IGNORE TABLE. Much less data will be lost that way and it's acceptable in this case (it's better than leaving it as it is now in longer time perspective).
The question is how to fill those fields from each duplicate.
Here is a rough try.
First try to find out the no. of rows which have the same key.
<?php
// $link is the database identifier
$sql = 'SELECT COUNT(*) AS num, * FROM `customerProjectData` GROUP BY `idCustomer`, `idProject` HAVING COUNT(*) > 1 ORDER BY COUNT(*) ASC;';
$run = mysql_query( $sql, $link );
$rows = array();
if( $run && mysql_num_rows( $run ) ) {
while( ( $fetch = mysql_fetch_assoc( $run ) ) !== false ) {
$rows[] = $fetch;
}
}
?>
Now $rows contains a list of all rows which have the same key and a count of how many times this key has been repeated in the table.
You can write a function which then iterates count times and see which rows has the complete data and use that to populates other records with this record's data.
A bit of trial and error.
I used #web-nomad suggestion and did something similar, but in sql procedure:

Thanks for help!
Is this a good candidate for a MERGE command?
Must the source data also be another table or can it be variables that are passed?
If it must be a table, is inserting the passed variables into a temp table sane?
Could you help me with the syntax?
CREATE PROCEDURE [dbo].[usp_ConvertToMerge]
