I have the following query:
SELECT
COUNT(*) over () as countNum,
[F1] AS STANDARDandOBJ,
[F2] AS CLUSTER,
[F3] AS OBJECTIVE,
[F4] AS EXTRA0
IF COL_LENGTH([tmpExcelDB].[dbo].['Blahsing$'], [F5]) IS NOT NULL
BEGIN
print 'exists'
END
ELSE
BEGIN
print 'Nope'
END,
CONCAT([F1], [F2]) AS combined
FROM
[tmpExcelDB].[dbo].['Blahsing$']
WHERE
LOWER(F3) NOT LIKE 'course tools-%'
But it seems that I have an error of:
Incorrect syntax near ','.
Which is pointing to row:
,CONCAT([F1], [F2]) AS combined
How does this need to be formatted in order to work?
You can't use IF inside a SELECT, you need a CASE expression. Also, it doesn't make sense to use PRINT inside a column:
SELECT
COUNT(*) over () as countNum
,[F1] AS STANDARDandOBJ
,[F2] AS CLUSTER
,[F3] AS OBJECTIVE
,[F4] AS EXTRA0
,CASE
WHEN COL_LENGTH('[tmpExcelDB].[dbo].[''Blahsing$'']', '[F5]') IS NOT NULL
THEN 'exists'
ELSE 'Nope'
END
,CONCAT([F1], [F2]) AS combined
FROM [tmpExcelDB].[dbo].['Blahsing$']
WHERE
LOWER(F3) NOT LIKE 'course tools-%';
SELECT
COUNT(*) over () as countNum
,[F1] AS STANDARDandOBJ
,[F2] AS CLUSTER
,[F3] AS OBJECTIVE
,[F4] AS EXTRA0 ,
( CASE When COL_LENGTH([tmpExcelDB].[dbo].['Blahsing$'], [F5]) IS NOT NULL
THEN
'exists'
ELSE
'Nope'
END),
CONCAT([F1], [F2]) AS combined
FROM [tmpExcelDB].[dbo].['0812 Orientation to Nursing$']
WHERE LOWER(F3)NOT LIKE 'course tools-%'
Couple things:
IF...ELSE is not supported in a select list, use CASE instead
PRINT is not supported in a select list, just the literal string value is needed
See the CASE Documentation for a relevant example.

Trying to make a select query on teradata, but i get this message error:
syntax error: invalid select expression list
I can't fix it. How can I formulate the query appropriately?

Consider I have text from the field (notes) as below:
Please check http://example.com
I want a SQL query which fetches the link part only. That is to find keyword http and print till the last.
Output:
http://example.com
Also if the text field doesnt have any link, can we print NA?
CASE WHEN sys like '%Clo%'
THEN RIGHT( i.notes,LEN(i.notes) - CHARINDEX('http',i.notes,1)+1)
ELSE "No Link Available" END AS Cl_Link
For SQL Server you can consider this below logic-
DECLARE #T VARCHAR(MAX) = 'Please check http://example.com'
SELECT RIGHT(#T,LEN(#T) - CHARINDEX('http:',#T,1)+1)
For MySQL-
SET #T = 'Please check http://example.com';
SELECT RIGHT(#T,LENGTH(#T) - POSITION("http:" IN #T)+1)
In case of select query using table, queries will be-
-- SQL Server
SELECT RIGHT(column_name,LEN(column_name) - CHARINDEX('http:',column_name,1)+1) FROM your_table_name
-- MySQL
SELECT RIGHT(column_name,LENGTH(column_name) - POSITION("http:" IN column_name)+1) FROM your_table_name
To apply 'NA' when no link available, please use the below logic-
DECLARE #T VARCHAR(MAX) = 'Please check http://example.com'
SELECT
CASE
WHEN CHARINDEX('http:',#T,1) >= 1 THEN RIGHT(#T,LEN(#T) - CHARINDEX('http:',#T,1)+1)
ELSE 'NA'
END
Below is the query for your reference, executed on mysql:
SELECT substr(columnname,locate('http',columnname)) as link
FROM `tablename` where column=value
For MySQL try this:
select REGEXP_SUBSTR(text_column, 'http\:\/\/([\\w\\.\\S]+)') from mytest
I'm getting the following error when I run this database view in psql (ERROR: division by zero). Even I can't access my table in rails console If anyone has any solution for this error so please comment on it will be very helpful thanks in advance.
select
(exam_id || '00' || quarter)::bigint as id,
account_id,
exam_id,
quarter,
quarter_label,
count(id) as assessments,
max(banding_percentage) as top_assessment_percentage,
min(banding_percentage) as bottom_assessment_percentage,
round(avg(banding_percentage),2) as avg_assessment_percentage
from report_assessments
group by account_id, exam_id, quarter, quarter_label;
To avoid running into division by zero exceptions you should use nullif, so that you can catch this 0 and replace it by null, e.g.
WITH j (v1,v2) AS (
VALUES (1.0,0.0),(10.0,3.0)
)
SELECT v1/nullif(v2,0) AS div FROM j;
div

You Need to do something like this.
It works in my case:
Negotiation.find(
:all,
conditions: conditions_hash('negotiation'),
select:
'CASE
sum(banding_percentage)
WHEN
0
THEN
NULL
ELSE
sum(total_percentage) / sum(banding_percentage)
END as error_check'
).first
Not letting me create the procedure, nor not letting run this query please help.
It's not letting run the query .. this is just a section of query
You had a few things wrong, you didnt need the parens, you were missing an End Statement, and your indents made it hard to read, and you are missing your FROM statement, so I put FROM and added tableName you need to fill this in.
create proc [dbo].[a_test]
as
begin
SELECT top 10
file_ty = '5',
cno= rtrim(ltrim(adm.AccountNumber)),
Column3='',
Column4='',
Admit_Date =
CASE
WHEN RegistrationType_MisRegTypeID <>'IN'
THEN ''
ELSE CONVERT(varchar(10),replace(convert(varchar(10),adm.AdmitDateTime,101),'/ ',''))
END,
Point_Of_Origin =
CASE
WHEN RegistrationType_MisRegTypeID='IN' then
CASE
WHEN AdmitSource='CIR' then '2'
WHEN AdmitSource='BSH' then '2'
ELSE ''
END
END
FROM dbo.TableName

I know the following is legitimate SQL query, but why this cannot be interpreted in SQL Server Compact? (I'm using SQL Server Compact view)
Select
Case AStatus
When 1 then 'Success', 'AStatus', 'Expected:1'
When 0 then 'Faliure', 'AStatus', 'Recived: 0'
end
From Statuses
Where LocalPath= 'c:\Status
I get something like:
Query 1 : There was an error parsing the query [Token line number=3, Token line offset=22, Token in Error=,]
And when writing something like the following it works:
Select
Case AStatus
When 1 then 'Success'
When 0 then 'Faliure'
end
From Statuses
Where LocalPath= 'c:\Status
I think that's the only valid way to get three columns from case:
Select
Case AStatus
When 1 then 'Success'
When 0 then 'Faliure'
END,
Case AStatus
When 1 then 'AStatus'
When 0 then 'AStatus'
END,
Case AStatus
When 1 then 'Expected:1'
When 0 then 'Recived: 0'
END
From Statuses
Where LocalPath= 'c:\Status'
EDIT:
Another way. Not much shorter, but seems more flexible:
Select
Astatus,
x.*
From Statuses s
CROSS APPLY (
select 'Success' as c1,'AStatus' as c2,'Expected:1' as c3 where AStatus=1 union all
select 'Failure' ,'AStatus','Recived:0' where AStatus=0
) x
Where LocalPath= 'c:\Status'
You get +1 for making me come up with that, I already know where I'll use it :).
Your statement is missing the END Cluase in the CASE statement I dont know if this is the only error try this 1st
Select
Case AStatus
When 1 then 'Success', 'AStatus', 'Expected:1'
When 0 then 'Faliure', 'AStatus', 'Recived: 0'
END
From Statuses
Where LocalPath= 'c:\Status
