CASE statement Conditions postgres - postgresql

I am trying to create a report for employees that start with the code 10....and apply a specific job code for them. They have a bad job code in the table.How and where do I check the condition in the case
statement ?
Example condition :
Apply job_code 'AC' for the employees that start with the code 10.
Table1 : customer_test
employee_code
Job_code_id
company_code
join_year
Table 2: Company_store
Job_code_id
Job_code
Company_code
Join_year
SELECT
ct.employee_code,ct.job_code_id old,ct.company_code ,cs.job_Code_id new ,cs.job_code new code,
CASE
WHEN (ct.employee_code LIKE '10%') THEN CAST(cs.job_Code_id AS varchar) //I need to apply the condition here? apply the specific job code id based on the conditions.
ELSE CAST(cs.job_Code_id AS varchar)
END AS REPORT
FROM customer_test ct,company_store cs
WHERE ct.company_code=cs.company_code
and ct.job_code_id =cs.job_code_id
and ct.join_year=cs.join_year;
Thanks in advance.

You could try something like:
case
when employee_code like '10%' then
(
select job_code
from customer_test
where employee_code ='AC'
)
else cast(job_Code as varchar(50))
end

Crystal formula case statement with like

I'm trying to convert sql case statement to crystal formula.
The select in sql had this in it:
...
,pf.Status_category AS Category
,CASE WHEN p.degree LIKE '%P%' AND
pf.department_name LIKE 'Occ%' THEN isnull(pf.department2, '') ELSE isnull(pf.department_name, '') END AS Department,
CASE WHEN p.degree LIKE '%P%' AND pf.department_name LIKE 'Occ%' THEN isnull(pf.Section2, '') ELSE isnull(pf.Section_name, '') END AS Section,
CASE WHEN p.degree LIKE '%P%' AND pf.department_name LIKE 'Occ%' THEN isnull(pf.department3, '') ELSE isnull(pf.department2, '') END AS [Department 2],
CASE WHEN p.degree LIKE '%P%' AND pf.department_name LIKE 'Occ%' THEN isnull(pf.Section3, '') ELSE isnull(pf.Section2, '') END AS [Section 2],
pdd.DepartmentName AS DP
,pdv.PrivilegeDetailText AS Privilages
...
FROM dbo.Person_PrivDtl_V AS pdv INNER JOIN
dbo.Person_Privs_Facs_V ON pdv.M_ID = dbo.Person_Privs_Facs_V.Person_Priv_M_ID INNER JOIN
dbo.PrivDefDepartments_PDF AS pdd ON pdd.PDDept_ID = pdv.PDDept_ID INNER JOIN
dbo.Person AS p ON pdv.Person_ID = p.Person_ID INNER JOIN
dbo.Person_Facilities AS pf ON pf.FacCode = dbo.Person_Privs_Facs_V.FacCode AND pdv.Person_ID = pf.Person_ID
When I convert this to crystal, I can't put this in the columns of the report design. So my idea is to use a formula for each column selected. I have this so far for the first formula, but it won't let me save it:
Formula name= Department:
select {Person_Facilities.Department_name}
case is like "Occ%" : {Person_Facilities.Department2}
The error seems to be the like. I looked up crystal like and it seems ok except for they use "is" for the accepted answer, but when I add "is" the error seems to be the "is" when I try to save it.
What is wrong with this formula so I can use like and the case?
Is there a better way to do this? I suppose I can use a view, but my boss doesn't want views cluttering the DB. Is using a formula the way to do this in crystal? The sql also handled null, which I'm not doing, but I'm not sure how to incorporate that at this point. I'm pretty new to crystal and my team doesn't like questions. We have Crystal Reports 2008 and SQL server 2008 R2.
Not sure if this is what you are looking for but try this;
select {Person_Facilities.Department_name}
case "Occ%" : {Person_Facilities.Department2}
default : 'Unknown';
The default is optional.
To use the LIKE operator, it is as follows;
If {Command_Main.Name} LIKE '*Manager*' then Do Something
To handle NULLS in CR, there is an option to do so in the formula editor. See below. Change it from Exception for Nulls to Default Values for Nulls.

How to delete a record using a Foreign Key

I want to delete all the records from QryCriteria where the CfgQryCriteriaId is the CfgQryCriteriaId from CfgQryCriteria
WHERE Criteria = 'PolicyAdministration.MDSL.Terms.LockInDate'
Below is what i have so far,can someone be of assistance?
BEGIN TRY
BEGIN TRANSACTION CFG
DELETE FROM QryCriteria
WHERE CfgQryCriteriaId = 'PolicyAdministration.MDSL.Terms.LockInDate'
END TRY
BEGIN CATCH
if(##TRANCOUNT >0)
ROLLBACK TRANSACTION CFG
END CATCH
An easy way is to use a subquery to get all of the appropriate CfgQryCriteria values:
delete from QryCriteria
where CfgQryCriteriaId in (
select COC.CfgQryCriteriaId from CfgQryCriteria as COC where COC.Criteria = 'PolicyAdministration.MDSL.Terms.LockInDate' );
A similar query could be constructed using where exists and a correlated subquery. A third choice would be deleting from an inner join between the two tables.

COALESCE command issue in Hive

I am trying to run a hive query using COALESCE function to create a view. But it is throwing error like
cannot recognize input near '(' 'SELECT' 'realvalue' in expression specification
The query is given below. Please help and mention what is wrong in this.
CREATE VIEW IF NOT EXISTS exampledb.`ara_service` AS
SELECT T1.EntityId, T1.entityname AS EntityName,
T1.`xxx`,
T1.`yyy`,
COALESCE (T1.`aaa`, (SELECT `realvalue` FROM exampledb.`aba_service`
WHERE `id` = '333')) AS `CombinedValue`,
T1.`ddd`,
T1.`jjj`,
etc..
Please help. The error is in the usage of the select statement inside COALESCE .
NoViableAltException(231#[435:1: precedenceEqualExpression : ( ( LPAREN precedenceBitwiseOrExpression COMMA )=> precedenceEqualExpressionMutiple | precedenceEqualExpressionSingle );])
Thanks
if all you need is a default value, you could do
CREATE VIEW IF NOT EXISTS exampledb.`ara_service` AS
SELECT T1.EntityId, T1.entityname AS EntityName,
T1.`xxx`,
T1.`yyy`,
COALESCE (T1.`aaa`, def.`realvalue` ) AS `CombinedValue`,
T1.`ddd`,
T1.`jjj`,
FROM your_table T1
CROSS JOIN (
SELECT `realvalue`
FROM exampledb.`aba_service` WHERE `id` = '333') def

update data using loop in sql syntax

I work with postgreSQL
I want to update email of all my users using sql
I have a table named user that contains 500 users,
so I think that I should use a loop in my sql syntax
For example when the table contains 4 users, I want the email for these users to become :
user1#hotmail.fr
user2#hotmail.fr
user3#hotmail.fr
user4#hotmail.fr
in java it should be like this
String newValue=null;
for(int i=0;i<list.size();i++)
{
newValue="user"+i+"#hotmail.fr";
// make update
}
I think that I should use plsql syntax
updated :
I try without success with this code :
BEGIN
FOR r IN SELECT * from user_
LOOP
NEXT r;
UPDATE user_ SET emailaddress = CONCAT('user',r,'#hotmail.fr')
END LOOP;
END
I solved the problem using this query :
UPDATE user_ SET emailaddress='user' || col_serial || '#hotmail.fr' FROM
(SELECT emailaddress, row_number() OVER ( ORDER BY createdate) AS col_serial FROM user_ ORDER BY createdate) AS t1
WHERE user_.emailaddress=t1.emailaddress

TSQL CTE Error: Incorrect syntax near ')'

I am developing a TSQL stored proc using SSMS 2008 and am receiving the above error while generating a CTE. I want to add logic to this SP to return every day, not just the days with data. How do I do this? Here is my SP so far:
ALTER Proc [dbo].[rpt_rd_CensusWithChart]
#program uniqueidentifier = NULL,
#office uniqueidentifier = NULL
AS
DECLARE #a_date datetime
SET #a_date = case when MONTH(GETDATE()) >= 7 THEN '7/1/' + CAST(YEAR(GETDATE()) AS VARCHAR(30))
ELSE '7/1/' + CAST(YEAR(GETDATE())-1 AS VARCHAR(30)) END
if exists (
select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#ENROLLEES')
) DROP TABLE #ENROLLEES;
if exists (
select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#DISCHARGES')
) DROP TABLE #DISCHARGES;
declare #sum_enrollment int
set #sum_enrollment =
(select sum(1)
from enrollment_view A
join enrollment_info_expanded_view C on A.enrollment_id = C.enroll_el_id
where
(#office is NULL OR A.group_profile_id = #office)
AND (#program is NULL OR A.program_info_id = #program)
and (C.pe_end_date IS NULL OR C.pe_end_date > #a_date)
AND C.pe_start_date IS NOT NULL and C.pe_start_date < #a_date)
select
A.program_info_id as [Program code],
A.[program_name],
A.profile_name as Facility,
A.group_profile_id as Facility_code,
A.people_id,
1 as enrollment_id,
C.pe_start_date,
C.pe_end_date,
LEFT(datename(month,(C.pe_start_date)),3) as a_month,
day(C.pe_start_date) as a_day,
#sum_enrollment as sum_enrollment
into #ENROLLEES
from enrollment_view A
join enrollment_info_expanded_view C on A.enrollment_id = C.enroll_el_id
where
(#office is NULL OR A.group_profile_id = #office)
AND (#program is NULL OR A.program_info_id = #program)
and (C.pe_end_date IS NULL OR C.pe_end_date > #a_date)
AND C.pe_start_date IS NOT NULL and C.pe_start_date >= #a_date
;WITH #ENROLLEES AS (
SELECT '7/1/11' AS dt
UNION ALL
SELECT DATEADD(d, 1, pe_start_date) as dt
FROM #ENROLLEES s
WHERE DATEADD(d, 1, pe_start_date) <= '12/1/11')
The most obvious issue (and probably the one that causes the error message too) is the absence of the actual statement to which the last CTE is supposed to pertain. I presume it should be a SELECT statement, one that would combine the result set of the CTE with the data from the #ENROLLEES table.
And that's where another issue emerges.
You see, apart from the fact that a name that starts with a single # is hardly advisable for anything that is not a local temporary table (a CTE is not a table indeed), you've also chosen for your CTE a particular name that already belongs to an existing table (more precisely, to the already mentioned #ENROLLEES temporary table), and the one you are going to pull data from too. You should definitely not use an existing table's name for a CTE, or you will not be able to join it with the CTE due to the name conflict.
It also appears that, based on its code, the last CTE represents an unfinished implementation of the logic you say you want to add to the SP. I can suggest some idea, but before I go on I'd like you to realise that there are actually two different requests in your post. One is about finding the cause of the error message, the other is about code for a new logic. Generally you are probably better off separating such requests into distinct questions, and so you might be in this case as well.
Anyway, here's my suggestion:
build a complete list of dates you want to be accounted for in the result set (that's what the CTE will be used for);
left-join that list with the #ENROLLEES table to pick data for the existing dates and some defaults or NULLs for the non-existing ones.
It might be implemented like this:
… /* all your code up until the last WITH */
;
WITH cte AS (
SELECT CAST('7/1/11' AS date) AS dt
UNION ALL
SELECT DATEADD(d, 1, dt) as dt
FROM cte
WHERE dt < '12/1/11'
)
SELECT
cte.dt,
tmp.[Program code],
tmp.[program_name],
… /* other columns as necessary; you might also consider
enveloping some or all of the "tmp" columns in ISNULLs,
like in
ISNULL(tmp.[Program code], '(none)') AS [Program code]
to provide default values for absent data */
FROM cte
LEFT JOIN #ENROLLEES tmp ON cte.dt = tmp.pe_start_date
;
