I am building up a website and I am working on the search part of it at the moment, so what I am trying to do is create a stored procedure that I am able to call that returns the values that I need.
I have put this together so far, but this limits me to only being able to select for example one model_id. I want to be able to search for model_ids 1,2,3,4 (example).
I was thinking of adding the parameters in as a string like '1,2,3,4' then splitting them and adding it into a temp table then I could do something like -product_type_id IN (select * from p_product_type_id)
PROCEDURE `sp_advert_search_load`(
IN p_product_type_id varchar(255),
IN p_product_details_id INT,
IN p_advert_status_id INT,
IN p_advert_type_id INT,
IN p_manufacturer_id INT,
IN p_model_id INT,
IN p_mechanism_id INT,
IN p_calibre_id INT,
IN p_orientation_id INT,
IN p_chamber_type_id INT,
IN p_trigger_type_id INT,
IN p_condition_id INT,
IN p_barrel_type_id INT,
IN p_cased INT,
IN p_certificate_id INT ,
IN p_price_more_than FLOAT ,
IN p_price_less_than FLOAT)
BEGIN
SELECT * FROM all_information_without_images
WHERE (product_type_id IN (p_product_type_id) or p_product_type_id IS NULL)
and (product_details_id = p_product_details_id or p_product_details_id IS NULL)
and (advert_status_id = p_advert_status_id or p_advert_status_id IS NULL)
and (advert_type_id = p_advert_type_id or p_advert_type_id IS NULL)
and (manufacturer_id = p_manufacturer_id or p_manufacturer_id IS NULL)
and (model_id = p_model_id or p_model_id IS NULL)
and (mechanism_id = p_mechanism_id or p_mechanism_id IS NULL)
and (calibre_id = p_calibre_id or p_calibre_id IS NULL)
and (orientation_id = p_orientation_id or p_orientation_id IS NULL)
and (chamber_type_id = p_chamber_type_id or p_chamber_type_id IS NULL)
and (trigger_type_id = p_trigger_type_id or p_trigger_type_id IS NULL)
and (condition_id = p_condition_id or p_condition_id IS NULL)
and (barrel_type_id = p_barrel_type_id or p_barrel_type_id IS NULL)
and (cased = p_cased or p_cased IS NULL)
and (certificate_id = p_certificate_id or p_certificate_id IS NULL)
and (price >= p_price_more_than or p_price_more_than IS NULL)
and (price <= p_price_less_than or p_price_less_than IS NULL);
END
Is there a better way I could achieve this? I suspect creating the temp tables is going to slow everything down quite a lot. Any pointers would be very helpful.
Thanks,
Richard
I have tried to use a prepared statement:
PROCEDURE `sp_advert_search_load`(
IN p_product_type_id varchar(255),
BEGIN
set #sql = concat( 'SELECT * FROM all_information_without_images
WHERE (product_type_id IN (',p_product_type_id,'))
');
PREPARE stmt FROM #sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END
But I am getting an error 1615 - Prepared statement needs to be re-prepared is might be worth noting that all_information_without_images is a view.
I was thinking about just adding my view code to the prepared statement but it is very long and I think it exceeds the max length.
I am running out of ideas here.
Hello for anyone that wants to know how I managed to do this here is the code below:
First I used a function to split strings like '1,2,3,4' and insert then into a temp table:
BEGIN
# Temp table variables
SET #tableName = 'tmpSplit';
SET #fieldName = 'variable';
# Dropping table
SET #sql := CONCAT('DROP TABLE IF EXISTS ', #tableName);
PREPARE stmt FROM #sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
# Creating table
SET #sql := CONCAT('CREATE TEMPORARY TABLE ', #tableName, ' (', #fieldName, ' VARCHAR(1000))');
PREPARE stmt FROM #sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
# Preparing toSplit
SET #vars := toSplit;
SET #vars := CONCAT("('", REPLACE(#vars, ",", "'),('"), "')");
# Inserting values
SET #sql := CONCAT('INSERT INTO ', #tableName, ' VALUES ', #vars);
PREPARE stmt FROM #sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
# Returning record set, or inserting into optional target
IF target IS NULL THEN
SET #sql := CONCAT('SELECT TRIM(`', #fieldName, '`) AS `', #fieldName, '` FROM ', #tableName);
ELSE
SET #sql := CONCAT('INSERT INTO ', target, ' SELECT TRIM(`', #fieldName, '`) FROM ', #tableName);
END IF;
PREPARE stmt FROM #sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END
Then the main store prod created a temp table then used the function to insert a varchar value into a temp table then
WHERE
CASE WHEN #product_type_id = ''
THEN information_view.product_type_id = information_view.product_type_id
ELSE information_view.product_type_id IN (select * from tm_product_type_id)end;
PROCEDURE `sp_advert_search_load`(
IN p_product_type_id varchar(255)
)
BEGIN
DROP TEMPORARY TABLE IF EXISTS tm_product_type_id;
CREATE TEMPORARY TABLE tm_product_type_id (product_type_id int);
SET #product_type_id = ifnull(p_product_type_id,'');
CALL sp_split(#product_type_id,'tm_product_type_id');

I'm somewhat of a SQL rookie but I'm trying to write a pivot between three tables. I have the below query and it works perfectly aside from the MAX call. It causes my values that are less than the default value to be overridden. I have screenshots of my tables below. Any ideas on how to fix this?
SET #sql = NULL;
SELECT
GROUP_CONCAT(DISTINCT
CONCAT(
'MAX(IF(cc.company_config_key_id = ', cck.id, ', cc.config_value, \'', cck.default, '\')) AS ', cck.company_config_key
)
) INTO #sql
FROM company_config cc
LEFT JOIN company_config_key cck
ON cck.id = cc.company_config_key_id;
SET #sql = CONCAT('SELECT co.id, co.name, ', #sql, ' FROM companies co LEFT JOIN company_config cc ON cc.company_id = co.id GROUP BY co.id');
PREPARE stmt FROM #sql;
EXECUTE stmt;
companies:
company_config_key:
company_config:
Result (the secondary colors for companies 1 and 2 should be set):
It turns out I just had to set the internal if statement to NULL and then wrapped the max statement in an IFNULL.
SET #sql = NULL;
SELECT
GROUP_CONCAT(DISTINCT
CONCAT('IFNULL(MAX(IF(cc.company_config_key_id = ', cck.id, ', cc.config_value, NULL)), \'', cck.default, '\') AS ',cck.company_config_key)
) INTO #sql

SET #sql = CONCAT('SELECT co.id, co.name, ', #sql, ' FROM companies co LEFT JOIN company_config cc ON cc.company_id = co.id GROUP BY co.id');

If I have this schema
lists (lead_id, list_id, campaign_id, ...)
campaign (campaign_id, ...)
custom_list_id (lead_id, ...)
there are many tables with name custom_list_id for various list_id s and I want to:
SELECT * from lists ls inner join campaign c ON c.id=ls.campaign_id
inner join custom_"#LISTID" cll ON ls.lead_id = cll.lead_id
How do I write this query?
thnx
Not sure what sql you really want, but try this:
SET #sql = NULL;
SELECT
GROUP_CONCAT(DISTINCT
CONCAT(
'INNER JOIN custom_', list_id, 'cll', list_id, ' ON ls.lead_id = cll', list_id '.lead_id')
)

I need to create a SQL query that lists the following tables. Lines from the language list as column names. Thanks
Picture table and query:
If languages are known upfront
SELECT r.id, r.parent,
MAX(CASE WHEN n.language_id = 1 THEN n.name END) cs,
MAX(CASE WHEN n.language_id = 2 THEN n.name END) en
FROM cat_route r LEFT JOIN cat_route_name n
ON r.id = n.cat_route_id
GROUP BY r.id
Here is SQLFiddle demo
If you want it to be dynamic depending on what languages you defined in language
SET #sql = NULL;
SELECT GROUP_CONCAT(CONCAT(
'MAX(CASE WHEN n.language_id = ', id, ' THEN n.name END) `', short, '`'))
INTO #sql
FROM language;
SET #sql = CONCAT(
'SELECT r.id, r.parent, ', #sql, '
FROM cat_route r LEFT JOIN cat_route_name n
ON r.id = n.cat_route_id
GROUP BY r.id');
PREPARE stmt FROM #sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
