I am getting mysql #1064 error while trying to create a view

This isn't a complete answer, but may contain enough info to get you started....
Typically (but not everytime), a VIEW into a set of database tables does not have a WHERE clause, and in your case the WHERE clause looks like a dog's breakfast.
I'd start with this much simpler view and develop from here....
CREATE VIEW trip_summary AS
SELECT
dd.`DriverId`,
CONCAT(dd.Firstname, ' ', dd.Lastname, ' ', dd.TaxiPlateNo) AS TaxiDriver,
count(tt.AutoId) AS TotalTrip,
GROUP_CONCAT(tt.AutoId) AS TripIds,
sum(tt.TripDistance) AS TotalTripDistance,
sum(tt.TotalFare) AS TotalTripFare
FROM `driver_details` AS dd
LEFT JOIN `taxi_trip` AS tt
ON tt.`DriverId` = dd.`DriverId`
AND tt.`PickupLAT` != 0
AND tt.`DropLAT` != 0
AND tt.`TotalFare` != 0
GROUP BY tt.DriverId
Then when you query the view, you select what you do and don't want out of the view by means of the where clause
SELECT * FROM trip_summary WHERE DriverID=1234;
This is the correct query to create the view which i need
CREATE VIEW trip_summary AS
select
`driver_details`.`DriverId`,
CONCAT(driver_details.Firstname, ' ', driver_details.Lastname, ' ',
driver_details.TaxiPlateNo) AS TaxiDriver,
count(taxi_trip.AutoId) AS TotalTrip,
GROUP_CONCAT(taxi_trip.AutoId) AS TripIds,
sum(taxi_trip.TripDistance) AS TotalTripDistance,
sum(taxi_trip.TotalFare) AS TotalTripFare
from `driver_details`
left join `taxi_trip`
on (`taxi_trip`.`DriverId` = `driver_details`.`DriverId`
and `taxi_trip`.`PickupLAT` != 0
and `taxi_trip`.`DropLAT` != 0
and `taxi_trip`.`TotalFare` != 0)
where taxi_trip.AutoId!=0
and
CASE
WHEN `DriverIdFun`()!=''
THEN taxi_trip.DriverId = `DriverIdFun`()
ELSE
TRUE
END
AND
CASE
WHEN `From_Date`()!=''
THEN taxi_trip.RequestDate >= `From_Date`()
ELSE
TRUE
END
AND
CASE
WHEN `To_Date`()!=''
THEN taxi_trip.RequestDate <= `To_Date`()
ELSE
TRUE
END
group by taxi_trip.DriverId

I'm trying to run a somewhat complex sql statement using the 'group_concat' function for statistics.
When I run the sql statement using navicat, the correct result is returned.But when I use mybatis debug this sql in idea, it returns null value.
I use HashMapHashMap<String,Long> to receive the result set executed by mybatis,
I guess the result set returned by mybatis executing sql is wrongly encapsulated.
But I tried for a long time and couldn't find a solution.
I can't post pictures here,I display the results in a table.
cha
hege
lianghao
youxiu
1
1
2
1
Receive declaration at the mapper layer
HashMap<String, Long> getOption(#Param("column") String column);
Here is the sql code:
<select id="getOption" resultType="java.util.HashMap">
SELECT GROUP_CONCAT(form.cha SEPARATOR '') cha,
GROUP_CONCAT(form.hege SEPARATOR '') hege,
GROUP_CONCAT(form.lianghao SEPARATOR '') lianghao,
GROUP_CONCAT(form.youxiu SEPARATOR '') youxiu
FROM (
SELECT
( CASE WHEN #{column} = '0' THEN count(*) ELSE NULL END) AS 'cha',
( CASE WHEN #{column} = '1' THEN count(*) ELSE NULL END ) AS 'hege',
( CASE WHEN #{column} = '2' THEN count(*) ELSE NULL END ) AS 'lianghao',
( CASE WHEN #{column} = '3' THEN count(*) ELSE NULL END ) AS 'youxiu'
FROM corp_feedback_student
GROUP BY #{column}
) form
</select>

case

How can I use it in where clause?
I tried zo directly use that CASE statement in where clause, but failed.
WHERE Trade.SecurityId = #SecurityId AND PortfolioId = #GHPortfolioID AND
(case when (Buy = 1 and Long = 1) then 1 when (Buy = 0 and Long = 0) then 1 else 0 end Position = 1)
The SQL-Server docs says:
column_alias can be used in an ORDER BY clause, but it cannot be used in a WHERE, GROUP BY, or HAVING clause.
Similar in the MySQL doc it says:
Standard SQL disallows references to column aliases in a WHERE clause. This restriction is imposed because when the WHERE clause is evaluated, the column value may not yet have been determined.
In MySQL you can at least reuse aliases in the SELECT clause
You can't, not directly.
If you wrap the whole query in a sub-query, however, it works fine.
SELECT
*
FROM
(
SELECT
Trade.TradeId,
Isnull(Securities.SecurityType,'Other') SecurityType,
TableName,
CASE
WHEN SecurityTrade.SecurityId IS NOT NULL THEN SecurityTrade.SecurityId
ELSE Trade.SecurityId
END AS PricingSecurityID,
sum(Trade.Quantity)OVER(Partition by Securities.SecurityType,
SecurityTrade.SecurityId,Trade.Price, Buy,Long ) as sumQuantity,
--added porfolio id for Getsumofqantity
Trade.PortfolioId,
Trade.Price,
case
when (Buy = 1 and Long = 1) then 1
when (Buy = 0 and Long = 0) then 1
else 0
end Position
from
Fireball_Reporting..Trade
where
porfolioid = 5
)
AS data
WHERE
Position = 1
This means that you don't need to repeat the CASE statement in WHERE clause. (Maintainable and DRY).
It is also a structure that allows the optimiser to behave as if you had simply repeated yourself in the WHERE clause.
It's also very portable to other RDBMSs.
In SQL Server, then you also have another option...
SELECT
Trade.TradeId,
Isnull(Securities.SecurityType,'Other') SecurityType,
TableName,
CASE
WHEN SecurityTrade.SecurityId IS NOT NULL THEN SecurityTrade.SecurityId
ELSE Trade.SecurityId
END AS PricingSecurityID,
sum(Trade.Quantity)OVER(Partition by Securities.SecurityType,
SecurityTrade.SecurityId,Trade.Price, Buy,Long ) as sumQuantity,
--added porfolio id for Getsumofqantity
Trade.PortfolioId,
Trade.Price,
position.val AS Position
from
Fireball_Reporting..Trade
CROSS APPLY
(
SELECT
case
when (Buy = 1 and Long = 1) then 1
when (Buy = 0 and Long = 0) then 1
else 0
end AS val
)
AS position
where
porfolioid = 5
AND position.val = 1
You can't directly do this...but you can wrap an additional select around it all and use the where clause:
select * from
( SELECT
Trade.TradeId,
Isnull(Securities.SecurityType,'Other') SecurityType,
TableName,
CASE
WHEN
SecurityTrade.SecurityId IS NOT NULL
THEN
SecurityTrade.SecurityId
ELSE
Trade.SecurityId
END AS PricingSecurityID,
sum(Trade.Quantity)OVER(Partition by Securities.SecurityType, SecurityTrade.SecurityId,Trade.Price, Buy,Long ) as sumQuantity,
--added porfolio id for Getsumofqantity
Trade.PortfolioId,
Trade.Price,
case
when (Buy = 1 and Long = 1) then 1
when (Buy = 0 and Long = 0) then 1
else 0
end Position
from
Fireball_Reporting..Trade
where porfolioid =5 and Position =1
)x
where x.position = 1
I'm probably missing something but surely this will cover it:
WHERE (Buy = 1 and Long = 1) OR (Buy = 0 and Long = 0)
I would like to use if statement in sql query :
what I want :
if(tractions_delivery.send_date_id !=0 ){
date_send_commodities.id = tractions_delivery.send_date_id
}
my query :
from
tractions_delivery,user_address,province,city,date_send_commodities,users
WHERE
tractions_delivery.tr_id = $tr_id
AND
tractions_delivery.address_id = user_address.id
AND
user_address.province_id = province.id
AND
user_address.city_id = city.id
AND
//not work
(tractions_delivery.send_date_id IS NOT 0 date_send_commodities.id = tractions_delivery.send_date_id)
AND
users.id = user_address.user_id
You could use the CASE-statement
SELECT
*
FROM
tractions_delivery,
user_address,
province,
city,
date_send_commodities,users
WHERE
tractions_delivery.tr_id = $tr_id AND
tractions_delivery.address_id = user_address.id AND
user_address.province_id = province.id AND
user_address.city_id = city.id AND
CASE WHEN tractions_delivery.send_date_id != 0 THEN date_send_commodities.id = tractions_delivery.send_date_id ELSE 1=1 END AND
users.id = user_address.user_id
You can only use if statements in stored procedures or functions. If you just write a sql statement unfortunately you cannot use if statements around the query. But you can use logic in the query itself, e.g.:
SELECT CASE WHEN col1 = col2 THEN'col1 equals col2' else 'col1 doesnt equal col2' ELSE
FROM table1
So around doesnt work, but in the field list you can create CASE WHEN ELSE END logic.
CASE or IF() operators can be of help.
Examples,
SELECT (CASE 1 WHEN 1 THEN 'One' WHEN 2 THEN 'Two' ELSE 'More' END) 'Result';
OR
SELECT IF(1=1, 'One', 'Two') 'Result';
These CASE and IF() operators can be used in the SELECT clause to conditionally interpret column values and return in the resultset.
Note: Do not confuse CASE operator here with 'CASE conditional syntax block' that ends with END CASE.
Trying to convert below query into SQL, query works fine on MySQL. Problem seems to be the CASE WHEN area field I get same error.

I'll toss my hat in the ring.
There may be more than one thing wrong with that SQL statement. What I'll point out is this:
CASE WHEN ((SELECT COUNT(1) FROM [QESTORM].[dbo]. [CR_TicketApproval] WHERE [Ticket_ID]=#iTkID And [Active]=1) = 0)
THEN
--ERROR SHOW HERE => ((T.[AuditUser_ID] = '444' OR T.[AuditUser_ID] IS NULL) AND (nx.actor = 2 OR appSameSeq.NTLogin=in_NTLogin)
AND nx.actor=3
AND srSameSeq.subRouteID NOT IN (SELECT subRouteID FROM [QESTORM].[dbo].[CR_TicketApproval] WHERE [Ticket_ID]=#iTkID AND Active=1 )
AND appSameSeq.NTLogin=in_NTLogin
AND nx.actor=3 AND srSameSeq.subRouteID NOT IN (SELECT subRouteID FROM [QESTORM].[dbo].[CR_TicketApproval] WHERE [Ticket_ID] = #iTkID AND Active = 1)
ELSE 0
END
Are you trying to evaluate a conditional expression, and return the result as a 1 or 0, as if it were a Boolean expression in a programming language?
That doesn't work in TSQL. This kind of expression evaluation:
SET #value = (1 > 0)
... will produce an error. You can't evaluate a conditional expression: you can only use it in a test, like in a WHERE, HAVING, or WHEN clause.
So, if that's what you're doing, you might do better to wrap your conditional evaluation in yet another CASE statement, like this:
THEN
CASE WHEN {complex conditional statement}
THEN 1
ELSE 0
END
ELSE
0
END
One other thing: this is an extremely complex query statement! I haven't analyzed it enough to see whether it could be simplified, but I'd suggest that you do so, with an eye toward using Common Table Expressions in place of some of your subqueries. This can make the query a lot easier to understand (and debug).
We are missing the complete query but it looks like you are opening too many parentheses.
If you look at the line where your error is shown:
((T.[AuditUser_ID] = '444' OR T.[AuditUser_ID] IS NULL) AND (nx.actor = 2 OR appSameSeq.NTLogin=in_NTLogin)
You are opening 2 parentheses but only close one.
That is why you get the error near else because you need to close that second parentheses before you can have an else
So you would need either
((T.[AuditUser_ID] = '444' OR T.[AuditUser_ID] IS NULL) AND (nx.actor = 2 OR appSameSeq.NTLogin=in_NTLogin))
or
(T.[AuditUser_ID] = '444' OR T.[AuditUser_ID] IS NULL) AND (nx.actor = 2 OR appSameSeq.NTLogin=in_NTLogin)
on that line
It looks like you don't have a 'return value' for your case statement on that specific line.
When you flatten your CASE WHEN statement you have something like this:
CASE WHEN <something> THEN
CASE WHEN <something else> THEN
CASE WHEN <something else again> THEN
-- THEN WHAT ?
ELSE
0
END
END
END
Instead of putting a value on the --THEN WHAT spot, you put another conditional statement. You have to select a value here.
I am using two tables here projections_report p and access_rights a. I can't find out why I am getting the error:
subquery returns more than one row
(case when paramChannel='AllC' then p.gl_sal_chan in
(case when dc_lob=0 then (select distinct pr.gl_sal_chan from
projections_report pr) else (select distinct pr1.gl_sal_chan
from projections_report pr1 where pr1.gl_sal_chan
in (select distinct a.gl_sal_chan from access_rights
a where a.userid= paramUserId)) end)
else p.gl_sal_chan = paramChannel end)
I tried using all and any keywords. Please help.
Thanks in advance.
USE LIMIT in sub queries to return only one record as you are using distinct, it might return more than one record
I tried to do it in another way and got it right. Firstly I changed the statement in else condition of second case statement to
(select distinct gl_sal_chan from access_rights where userid = paramUserid)
as both return the same result(my bad) and secondly I changed the entire condition to
(case when (paramChannel = 'AllC' && dc_lob = 0) then '%' = '%' else
(case when (paramChannel='AllC' && dc_lob != 0) then
gl_sal_chan in (select distinct gl_sal_chan from access_rights where userid = paramUserid)
else gl_sal_chan= paramChannel end)end)
Anyway Thanks #all :)
