I would need your help to fix a problem I'm facing.. I'm using a CASE function and aliasing its result by adding "AS 'RESULT'" after its "END".
Event though the query seems to run, I'm still getting the following warnings through phpmyadmin :
Unrecognized keyword (near AS)
Unexpected token (near 'RESULT')
I have no idea on why I'm getting this...I would appreciate your help to highlight my mistake ;-)

Have you tried removing the parentheses around the CASE statement?
CASE
WHEN #counterStatus = 'Counting' AND #counter < 0 THEN "black"
WHEN #counterStatus = 'Counting' AND #counter > 5 THEN "green"
WHEN #counterStatus = 'Counting' AND -1 < #counter < 5 THEN "orange"
WHEN #counterStatus = 'Complete' AND #counter > 35 THEN "black"
WHEN #counterStatus = 'Complete' AND #counter < 35 THEN "green"
ELSE "n/a"
END AS 'RESULT'
EDIT: I'm also not sure this is possible:
WHEN #counterStatus = 'Counting' AND -1 < #counter < 5 THEN "orange"
It may need to be written as:
WHEN #counterStatus = 'Counting' AND -1 < #counter AND #counter < 5 THEN "orange"

So I have string that should contains "Object.Name" once in a row , if I see it ,I have to get the value after "=" character. If doesn't match it anywhere in the string i should move hardcoded value.
Here is example of the string:
Object.Name=ASDD||Product.Name=DSA
Product.Name=QWE||Object.Name=WSXS
Storage.Name=12345||Object.Name=WERR||Product.Name=QAZ
I know that I should use case for that but doesn't know how to proceed the string
case
when (match the string ) then (value after the "=")
else (hardcoded value)
end
In Oracle, you can use:
SELECT value,
CASE
WHEN start_pos = 0
THEN NULL
ELSE SUBSTR(
'||' || value || '||',
start_pos + LENGTH('||Object.Name='),
end_pos - start_pos - LENGTH('||Object.Name=')
)
END AS object_name
FROM (
SELECT value,
INSTR(
'||' || value || '||',
'||Object.Name='
) AS start_pos,
INSTR(
'||' || value || '||',
'||',
INSTR('||' || value || '||', '||Object.Name=')+LENGTH('||Object.Name=')
) AS end_pos
FROM table_name
)
Which, for the sample data:
CREATE TABLE table_name (value) AS
SELECT 'Object.Name=ASDD||Product.Name=DSA' FROM DUAL UNION ALL
SELECT 'Product.Name=QWE||Object.Name=WSXS' FROM DUAL UNION ALL
SELECT 'Storage.Name=12345||Object.Name=WERR||Product.Name=QAZ' FROM DUAL;
Outputs:
VALUE
OBJECT_NAME
Object.Name=ASDD||Product.Name=DSA
ASDD
Product.Name=QWE||Object.Name=WSXS
WSXS
Storage.Name=12345||Object.Name=WERR||Product.Name=QAZ
WERR

Since you changed the tags, in MySQL:
SELECT value,
CASE
WHEN start_pos = 0
THEN NULL
ELSE SUBSTRING(
CONCAT('||', value, '||'),
start_pos + LENGTH('||Object.Name='),
end_pos - start_pos - LENGTH('||Object.Name=')
)
END AS object_name
FROM (
SELECT value,
LOCATE(
'||Object.Name=',
CONCAT('||', value, '||')
) AS start_pos,
LOCATE(
'||',
CONCAT('||', value, '||'),
LOCATE('||Object.Name=', CONCAT('||', value, '||'))
+ LENGTH('||Object.Name=')
) AS end_pos

I need some help with my SQL. I am attempting to get the following rows...

Sender
Code 1
Code 1 Score
Code 2
Code 2 Score
1
John Doe
AB
80
BA

2
Jane Doe
CD

DC

The code columns are the hard part. This is the relationships
Conversation -> Messages -> Highlights -> Codes.
Messages have a conversation_id
Messages Highlights have a message_id
Codes have a highlight_id
One conversation has many messages, Each Message has many Highlights, and any highlights have many codes.
SELECT
conversations.id,
CONCAT(senders.first_name, ' ', senders.last_name) as 'Sender Name'
conversations.created_at AS 'Start Date',
FROM
conversations
LEFT JOIN users AS senders ON sender.id = conversations.participant_1
LEFT JOIN users AS recipient ON recipient.id = conversations.participant_2
GROUP BY
conversations.name
I cannot figure out how to include the codes into the results as columns that a paired (Code 1 Name, Code Score).
The above query works to get the first few columns, but I'd like to join in the codes. Any help would be appreciated.
I have an idea to make use of row_number to create multiple columns
SELECT m.highlight_id,
MAX( CASE WHEN RN = 1 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 1 THEN m.code_score ELSE '' END ),
MAX( CASE WHEN RN = 2 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 2 THEN m.code_score ELSE '' END ),
MAX( CASE WHEN RN = 3 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 3 THEN m.code_score ELSE '' END ),
MAX( CASE WHEN RN = 4 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 4 THEN m.code_score ELSE '' END ),
MAX( CASE WHEN RN = 5 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 5 THEN m.code_score ELSE '' END )
FROM
(
SELECT
b.highlight_id, b.code_name, b.code_score, (CASE WHEN #T = b.highlight_id THEN #RN := #RN + 1 ELSE #RN := 1 END ) AS RN, #T := b.highlight_id
FROM highlights a
JOIN codes b ON a.highlight_id = b.highlight_id
JOIN (SELECT #T := '', #RN := 0) u
ORDER BY a.highlight_id, b.code_name
) m
GROUP BY m.highlight_id
;
If you are using MySQL 8.0, it's simpler
SELECT m.highlight_id,
MAX( CASE WHEN RN = 1 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 1 THEN m.code_score ELSE '' END ),
MAX( CASE WHEN RN = 2 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 2 THEN m.code_score ELSE '' END ),
MAX( CASE WHEN RN = 3 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 3 THEN m.code_score ELSE '' END ),
MAX( CASE WHEN RN = 4 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 4 THEN m.code_score ELSE '' END ),
MAX( CASE WHEN RN = 5 THEN m.code_name ELSE '' END ),
MAX( CASE WHEN RN = 5 THEN m.code_score ELSE '' END )
FROM (
SELECT b.highlight_id, b.code_name, b.code_score, ROW_NUMBER() OVER(PARTITION BY b.highlight_id ORDER BY b.code_name) RN
FROM highlights a
JOIN codes b ON a.highlight_id = b.highlight_id

There are two kind of function that return table. the inline function and multi-statement function. Yours is multi-statement. Here is the syntax for this:
--Transact-SQL Multistatement Table-valued Function Syntax
CREATE FUNCTION [ schema_name. ] function_name
( [ { #parameter_name [ AS ] [ type_schema_name. ] parameter_data_type
[ = default ] [READONLY] }
[ ,...n ]
]
)
RETURNS #return_variable TABLE <table_type_definition>
[ WITH <function_option> [ ,...n ] ]
[ AS ]
BEGIN
function_body
RETURN
END
[ ; ]
For more information refer to CREATE FUNCTION (Transact-SQL) BOL documentation.
You have to define the returned table's structure (fields and data types)
1) Add a variable name to the function definition (#tableVariable in the above example).
2) Fill the table definition (columns and datatypes)
3) Modify your function to insert the result into the defined table variable, then use an empty RETURN statement when the function should return.
1st step
CREATE FUNCTION WFSlaTimer
(
#OBJECT_PK_ID INT = 110
)
RETURNS #tableVariable TABLE (
IS_SHOW_SLA INT,
StartDate DATETIME2,
EndDate DATETIME2
/** List all of your returned columns like when you creating a table **/
)
AS
BEGIN
/** Do your stuff **/
INSERT INTO #tableVariable ( /* field list */) VALUES (/* value list */)
-- OR --
INSERT INTO #tableVariable ( /* field list */)
SELECT /* FieldList */ FROM myCTE
RETURN
END
2nd step
Modify your RETURN () statement like this:
INSERT INTO #tableVanriable (IS_SHOW_SLA , StartDate , EndDate)
SELECT
IS_SHOW_SLA = CASE WHEN #TIMER_START_ACTIVITY_COMPLETED_ON IS NULL
--OR #IS_OBJECT_STATUS_IS_TERMINAL = 1
--OR #TIMER_START_ACTIVITY_COMPLETED_ON IS NULL
THEN 0
ELSE 1 END,
#START_DATE AS [START_DATE], #END_DATE AS [END_DATE],
SLA_TYPE = #SLA_DISPLAY
/** .... **/

/** 3rd step **/

I have this query that does exactly what i want in phpmyadmin, it returns the number of visits my site has had. ex: visitorCount: 2204

set #last_tm = '00:00';
set #last_vid = 0;
SELECT MAX(
CASE WHEN #last_uid = visitorid AND cast( #last_tm as datetime) >= subtime( timestamp, '01:00' )

if( (#last_tm := timestamp ), #last_vid, #last_vid)
ELSE
if( (#last_uid := visitorid) + (#last_vid := #last_vid+1) +(#last_tm := timestamp ),#last_vid, #last_vid )
END
) as visitorCount

ORDER BY timestamp DESC, visitorid
When i try to execute this query from PHP however it doesen't work, i have tested with a regular php mysql connection and with cakephp $this->Model->query(); without any success, all i get from the query is "1" or true. Whats wrong?
$query = "set #last_uid = 0;

set #last_vid = 0;

if (!$con) {
die(mysql_error());
}
mysql_select_db("dbname", $con);
$result = mysql_query($query);
print_r(mysql_fetch_row($result));
Gives me the error message:
mysql_fetch_row() expects parameter 1 to be resource, boolean given
I'm not sure if it is because you are executing multiple statements but try combining it into one,
SELECT MAX(CASE WHEN #last_uid = visitorid AND cast( #last_tm as datetime) >= subtime( timestamp, '01:00' )
THEN if((#last_tm := timestamp), #last_vid, #last_vid)
ELSE if((#last_uid := visitorid) + (#last_vid := #last_vid+1) + (#last_tm := timestamp), #last_vid, #last_vid )

I'm stacked on following query. I need to create an if statement or something similar to distinguish which "CASE" should be added to my select query.
If page_type = 'Region' or 'City' add this to the query:
( CASE When landing_page like concat('%',path_id,'%') and
(LENGTH(landing_page) - LENGTH(REPLACE(landing_page, '/' ,'')) / LENGTH('/')) = 2
Then 'True' Else 'False' End as 'correct lp' , )
Elseif page_type = 'Item' add this to the query:
( CASE When landing_page like concat('%',path_id,'%') and
(LENGTH(landing_page) - LENGTH(REPLACE(landing_page, '/' ,'')) / LENGTH('/')) = 3
Then 'True' Else 'False' End as 'correct lp' , )
Elseif page_type = 'POI (Alle)' add this to the query:
( CASE When landing_page like concat('%',path_id,'%') and
(LENGTH(landing_page) - LENGTH(REPLACE(landing_page, '/' ,'')) / LENGTH('/')) = 3 and
'Hotel' NOT IN landing_page
Then 'True' Else 'False' End as 'correct lp' , )
Case queries should be added to the following query according to if outcome:
SELECT
MONTHNAME(k.crawl_date) As 'Month',
YEAR(k.crawl_date) As 'Year',
WEEKOFYEAR(k.crawl_date) As 'Week',
k.landing_page,
k.pos,
CASE WHEN k.pos = 0 THEN 'No Rank' WHEN k.pos < 4 THEN 'Top 3' WHEN k.pos < 11 THEN 'Page 1'
WHEN k.pos < 21 THEN 'Page 2' WHEN k.pos < 31 THEN 'Page 3' WHEN k.pos < 41 THEN 'Page 4'
WHEN k.pos < 51 THEN 'Page 5' WHEN k.pos < 61 THEN 'Page 6' WHEN k.pos < 71 THEN 'Page 7'
WHEN k.pos < 81 THEN 'Page 8' WHEN k.pos < 91 THEN 'Page 9' WHEN k.pos < 101 THEN 'Page 10'
WHEN k.pos < 111 THEN 'Page 11' END as 'Page',
k.path_id,
k.domain,
x.keyword,
x.engine_id,
l.bucket,
l.page_type,
l.item_label
FROM
xovi_stats k
LEFT JOIN xovi_keywords x ON k.keyword_id = x.id
LEFT JOIN xovi_labels l ON l.id = x.label_id
You can nest CASE clauses like this:
SELECT
CASE
WHEN (page_type IN ('Region', 'City')) THEN
CASE
WHEN landing_page LIKE ... THEN 'True'
ELSE 'False'
END
WHEN (page_type = 'Item') THEN
CASE
...
END
WHEN (page_type = 'POI (Alle)') THEN
CASE
...
END
END AS lp,
MONTHNAME(k.crawl_date) As 'Month', -- other fields
...
Or you can also nest IF(), as you suggest:
SELECT
IF ( (page_type IN ('Region', 'City')),
-- if (page_type IN ('Region', 'City')) then
CASE
WHEN landing_page LIKE ... THEN 'True'
ELSE 'False'
END,
-- else
IF ( (page_type = 'Item'),
-- if (page_type = 'Item') then
CASE
...
END,
-- else
IF ( page_type = 'POI (Alle)',
-- if (page_type = 'POI (Alle)') then
CASE
...
END,
-- else
NULL
)
)
) AS lp,
MONTHNAME(k.crawl_date) As 'Month', -- other fields
...
Off-topic notes:
you can replace your two-branch CASE statements with simple IF():
SELECT CASE
WHEN landing_page LIKE ... THEN 'True'
ELSE 'False'
END AS alias ;
-- strictly equivalent to
SELECT IF(
landing_page LIKE ...,
'True',
