I am going to execute SQL command on my multiplayer game, I don't wanna any game stop or something like that because I am going to lose players so everything must go smooth.
Its my command :
UPDATE `players`
SET `mana` = `mana` + 500 WHERE `vocation` != "121;122;123;124;125;126"
AND `id` IN (SELECT `player_id` FROM `player_storage` WHERE `key` = 25128 AND `value` = 15 GROUP BY `player_id`);
I want to update every vocation that is not 121 OR 122 OR 123 OR 124 OR 125 OR 126
You can use NOT IN to filter values that are not in a list.
WHERE vocation NOT IN (121, 122, 123, 124, 125, 126)
Use BETWEEN
....Where location
not between 120
and
127
If you have the list as a string of values with delimiter ; you can use FIND_IN_SET():
WHERE FIND_IN_SET(`vocation`, REPLACE('121;122;123;124;125;126', ';', ',')) = 0

Hi i need a complex query
my table structure is
attribute_id value entity_id
188 48,51,94 1
188 43,22 2
188 43,22 3
188 43,22 6
190 33,11 10
190 90,61 12
190 90,61 15
I need the count of the value like
attribute_id value count
188 48 2
188 43 3
188 51 1
188 94 1
188 22 2
190 33 1
190 11 1
190 90 2
190 61 2
I have searched a lot on google to have something like this but unfortunately i didn't get any success. Please suggest me how can i achieve this .
I use a UDF for things like this. If that could work for you:
CREATE FUNCTION [dbo].[UDF_StringDelimiter]
/*********************************************************
** Takes Parameter "LIST" and transforms it for use **
** to select individual values or ranges of values. **
** **
** EX: 'This,is,a,test' = 'This' 'Is' 'A' 'Test' **
*********************************************************/
(
#LIST VARCHAR(8000)
,#DELIMITER VARCHAR(255)
)
RETURNS #TABLE TABLE
(
[RowID] INT IDENTITY
,[Value] VARCHAR(255)
)
WITH SCHEMABINDING
AS
BEGIN
DECLARE
#LISTLENGTH AS SMALLINT
,#LISTCURSOR AS SMALLINT
,#VALUE AS VARCHAR(255)
;
SELECT
#LISTLENGTH = LEN(#LIST) - LEN(REPLACE(#LIST,#DELIMITER,'')) + 1
,#LISTCURSOR = 1
,#VALUE = ''
;
WHILE #LISTCURSOR <= #LISTLENGTH
BEGIN
INSERT INTO #TABLE (Value)
SELECT
CASE
WHEN #LISTCURSOR < #LISTLENGTH
THEN SUBSTRING(#LIST,1,PATINDEX('%' + #DELIMITER + '%',#LIST) - 1)
ELSE SUBSTRING(#LIST,1,LEN(#LIST))
END
;
SET #LIST = STUFF(#LIST,1,PATINDEX('%' + #DELIMITER + '%',#LIST),'')
;
SET #LISTCURSOR = #LISTCURSOR + 1
;
END
;
RETURN
;
END
;
The UDF takes two parameters: A string to be split, and the delimiter to split by. I've been using it for all sorts of different things over the years, because sometimes you need to split by a comma, sometimes by a space, sometimes by a whole string.
Once you have that UDF, you can just do this:
DECLARE #TABLE TABLE
(
Attribute_ID INT
,Value VARCHAR(55)
,Entity_ID INT
);
INSERT INTO #TABLE VALUES (188, '48,51,94', 1);
INSERT INTO #TABLE VALUES (188, '43,22', 2);
INSERT INTO #TABLE VALUES (188, '43,22', 3);
INSERT INTO #TABLE VALUES (188, '43,22', 6);
INSERT INTO #TABLE VALUES (190, '33,11', 10);
INSERT INTO #TABLE VALUES (190, '90,61', 12);
INSERT INTO #TABLE VALUES (190, '90,61', 15);
SELECT
T1.Attribute_ID
,T2.Value
,COUNT(T2.Value) AS Counter
FROM #TABLE T1
CROSS APPLY dbo.UDF_StringDelimiter(T1.Value,',') T2
GROUP BY T1.Attribute_ID,T2.Value
ORDER BY T1.Attribute_ID ASC, Counter DESC
;
I did an ORDER BY Attribute_ID ascending and then the Counter descending so that you get each Attribute_ID with the most common repeating values first. You could change that, of course.
Returns this:
Attribute_ID Value Counter

I have a table with columns showing ranges, like
id from to
1 10 100
2 200 300
I have a query which will be a list of values, like 17, 20, 44, 288 etc.
Is it possible to have a result set which would include the where condition, so I get:
id from to input
1 10 100 7
1 10 100 20
1 10 100 144
2 200 300 288
Right now the code runs one query per where value and it works, and I'm looking to increase performance by combing it into one large multiple where clause, like
SELECT *
FROM table
WHERE (from<=7 AND start>=7)
OR (from<=20 AND start>=20)
OR (from<=144 AND start>=144)
OR (from<=288 AND start>=288)
What you want makes no sense regarding ranges.
7 and 144 has no compatible range yet you want to put then into the first range.
In a result set with lots of values listing you will probably get to many conditions.
What you can do is to put those values that isn't in a range to show without correspondence. Like this:
With the structure being:
create table test (
id integer,
vfrom integer,
vto integer
);
insert into test values
(1, 10, 100),
(2, 200, 300);
create table vals(
val integer
);
insert into vals values (7), (20), (144), (288);
You can use this query:
select val, id, vfrom, vto
from vals v left join
test t on ( t.vfrom <= v.val and t.vto >= v.val )
It will bring you:
7 null null null
20 1 10 100
144 null null null
288 2 200 300
see it here on fiddle: http://sqlfiddle.com/#!2/f68fd/8
Maybe it isn't what you want but it is more logical.
Sure there is a query for this. Trouble is we need a table for specific values to show up; and then there are sub-queries and union selects:
SELECT table.*, values.val AS input
FROM (SELECT 7 AS val UNION SELECT 20 AS val UNION SELECT 144 AS val UNION SELECT 288 AS val) as values
JOIN table ON table.from <= values.val AND table.to >= values.val
This should do the trick. Note that you only have to specify the column name in the first SELECT with in a UNION SELECT.
I will suppose you are using Java as your application language. You could build your query this way:
public String buildQuery(int[] myList) {
String queryToReturn = "";
for (int queryIndex = 0; queryIndex < myList.length; queryIndex++) {
queryToReturn += ((queryIndex == 0) ? ("") : (" union ")) +
"(select `id`, `from`, `to`, " + myList[queryIndex] + " as input
from MyTable
where `from` < " + myList[queryIndex] + " and " + myList[queryIndex] " < `to`)";
}
return queryToReturn;
}
Then run the returned query.
I have a query which includes fields named openingbalance and commissions. I would like to compute values for commissions based on openingbalance, similar to this Select Case block in Access VBA:
Select Case OpeningBalance
Case 0 To 5000
commission = 20
Case 5001 To 10000
commission = 30
Case 10001 To 20000
commission = 40
Case Else
commission = 50
End Select
But since Access doesn't allow Select Case in a query, how can I accomplish my goal in Access SQL?
Consider the Switch Function as an alternative to multiple IIf() expressions. It will return the value from the first expression/value pair where the expression evaluates as True, and ignore any remaining pairs. The concept is similar to the SELECT ... CASE approach you referenced but which is not available in Access SQL.
If you want to display a calculated field as commission:
SELECT
Switch(
OpeningBalance < 5001, 20,
OpeningBalance < 10001, 30,
OpeningBalance < 20001, 40,
OpeningBalance >= 20001, 50
) AS commission
FROM YourTable;
If you want to store that calculated value to a field named commission:
UPDATE YourTable
SET commission =
Switch(
OpeningBalance < 5001, 20,
OpeningBalance < 10001, 30,
OpeningBalance < 20001, 40,
OpeningBalance >= 20001, 50
);
Either way, see whether you find Switch() easier to understand and manage. Multiple IIf()s can become mind-boggling as the number of conditions grows.
You can use IIF for a similar result.
Note that you can nest the IIF statements to handle multiple cases. There is an example here: http://forums.devshed.com/database-management-46/query-ms-access-iif-statement-multiple-conditions-358130.html
SELECT IIf([Combinaison] = "Mike", 12, IIf([Combinaison] = "Steve", 13)) As Answer
FROM MyTable;
You could do below:
select
iif ( OpeningBalance>=0 And OpeningBalance<=500 , 20,
iif ( OpeningBalance>=5001 And OpeningBalance<=10000 , 30,
iif ( OpeningBalance>=10001 And OpeningBalance<=20000 , 40,
50 ) ) ) as commission
from table
I have strings such as M1 M3 M4 M14 M30 M40 etc (really any int 2-3 digits after a letter)
When I do " ORDER BY name " this returns:
M1, M14, M3, M30, M4, M40
When I want:
M1, M3, M4, M14, M30, M40
Its treating the whole thing as a string but I want to treat it as string + int
Any ideas?
You could use SUBSTR and CAST AS UNSIGNED/SIGNED within ORDER BY:
SELECT * FROM table_name ORDER BY
SUBSTR(col_name FROM 1 FOR 1),
CAST(SUBSTR(col_name FROM 2) AS UNSIGNED)
If there can be multiple characters at the beginning of the string, for example like 'M10', 'MTR10', 'ABCD50', 'JL8', etc..., you basically have to get the substring of the name from the first position of a number.
Unfortunately MySQL does not support that kind of REGEXP operation (only a boolean value is returned, not the actual match).
You can use this solution to emulate it:
SELECT name
FROM tbl
ORDER BY CASE WHEN ASCII(SUBSTRING(name,1)) BETWEEN 48 AND 57 THEN
CAST(name AS UNSIGNED)
WHEN ASCII(SUBSTRING(name,2)) BETWEEN 48 AND 57 THEN
SUBSTRING(name,1,1)
WHEN ASCII(SUBSTRING(name,3)) BETWEEN 48 AND 57 THEN
SUBSTRING(name,1,2)
WHEN ASCII(SUBSTRING(name,4)) BETWEEN 48 AND 57 THEN
SUBSTRING(name,1,3)
WHEN ASCII(SUBSTRING(name,5)) BETWEEN 48 AND 57 THEN
SUBSTRING(name,1,4)
WHEN ASCII(SUBSTRING(name,6)) BETWEEN 48 AND 57 THEN
SUBSTRING(name,1,5)
WHEN ASCII(SUBSTRING(name,7)) BETWEEN 48 AND 57 THEN
SUBSTRING(name,1,6)
WHEN ASCII(SUBSTRING(name,8)) BETWEEN 48 AND 57 THEN
SUBSTRING(name,1,7)
END,
CASE WHEN ASCII(SUBSTRING(name,1)) BETWEEN 48 AND 57 THEN
CAST(SUBSTRING(name,1) AS UNSIGNED)
WHEN ASCII(SUBSTRING(name,2)) BETWEEN 48 AND 57 THEN
CAST(SUBSTRING(name,2) AS UNSIGNED)
WHEN ASCII(SUBSTRING(name,3)) BETWEEN 48 AND 57 THEN
CAST(SUBSTRING(name,3) AS UNSIGNED)
WHEN ASCII(SUBSTRING(name,4)) BETWEEN 48 AND 57 THEN
CAST(SUBSTRING(name,4) AS UNSIGNED)
WHEN ASCII(SUBSTRING(name,5)) BETWEEN 48 AND 57 THEN
CAST(SUBSTRING(name,5) AS UNSIGNED)
WHEN ASCII(SUBSTRING(name,6)) BETWEEN 48 AND 57 THEN
CAST(SUBSTRING(name,6) AS UNSIGNED)
WHEN ASCII(SUBSTRING(name,7)) BETWEEN 48 AND 57 THEN
CAST(SUBSTRING(name,7) AS UNSIGNED)
WHEN ASCII(SUBSTRING(name,8)) BETWEEN 48 AND 57 THEN
CAST(SUBSTRING(name,8) AS UNSIGNED)
END
This will order by the character part of the string first, then the extracted number part of the string as long as there are <=7 characters at the beginning of the string. If you need more, you can just chain additional WHENs to the CASE statement.
I couldn't get this working for my issue which was sorting MLS Numbers like below:
V12345
V1000000
V92832
The problem was V1000000 wasn't being valued higher than the rest even though it's bigger.
Using this solved my problem:
ORDER BY CAST(SUBSTR(col_name FROM 2) AS UNSIGNED) DESC
Just removed the SUBSTR(col_name FROM 1 FOR 1)
You can use:
order by name,SUBSTRING(name,1,LENGTH(name)-1)
It split number and letters as separately.
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(SUBSTRING_INDEX(SUBSTRING_INDEX(SUBSTRING_INDEX(SUBSTRING_INDEX(SUBSTRING_INDEX(
SUBSTRING_INDEX(SUBSTRING_INDEX(SUBSTRING_INDEX(col,'1', 1), '2', 1), '3', 1), '4', 1), '5', 1), '6', 1)
, '7', 1), '8', 1), '9', 1), '0', 1) as new_col
FROM table group by new_col;
Try remove the character with SUBSTR. Then use ABS to get the absolute value from field:
SELECT * FROM table ORDER BY ABS(SUBSTR(field,1));
Another method i used in my project is:
SELECT * FROM table_name ORDER BY LENGTH(col_name) DESC, col_name DESC LIMIT 1
I want to retrieve only the first part of a VARCHAR(15) string. Which string operation is fastest? My data is like this:
80:0:0:0
100:00:00:00
0:00:25:60
I'd like the results to be:
80
100
0
DECLARE #str TABLE(x VARCHAR(15));
INSERT #str VALUES ('80:0:0:0'), ('100:00:00:00'), ('0:00:25:60');
SELECT FirstPart = SUBSTRING(x, 1, CHARINDEX(':', x)-1) FROM #str;
Results:
FirstPart
---------
80
100
0
If you need to show the whole string even if it doesn't contain : then you can do this instead:
SELECT SUBSTRING(x, 1, COALESCE(NULLIF(CHARINDEX(':', x), 0), 15)) FROM #str;
