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 declare some filters on a form and pass them into my SP in SQL for running a select command and this is how I did that, but it didn't work:
DECLARE #Confirm_Filter AS BIT=NULL,
#ReciveDate_Filter AS NCHAR(10) = NULL
....
select * from .......
where
(#Confirm_Filter IS NOT NULL AND InterviewConfirm = #Confirm_Filter)
AND
(#ReciveDate_Filter IS NOT NULL AND ReciveDate BETWEEN GETDATE() AND #ReciveDate_Filter)
and in the where section I want to do:
where
if #Confirm_Filter IS NOT NULL Then (Select * from ... where InterviewConfirm = #Confirm_Filter)
AND
if #ReciveDate_Filter IS NOT NULL Then (select * from .... where ReciveDate BETWEEN GETDATE() AND #ReciveDate_Filter)
and I know above form is totally mistake but how could I do it?
Your problem is called dynamic search conditions. It is solved either by using dynamic SQL, or the following pattern (which is similar to your first version, but with a few changes):
select * from .......
where
(#Confirm_Filter IS NULL OR InterviewConfirm = #Confirm_Filter)
AND
(#ReciveDate_Filter IS NULL OR ReciveDate BETWEEN GETDATE() AND #ReciveDate_Filter)
I have a query that is passing the current year as a placeholder parameter that right now is hard coded. How can I have this just pass the current year? I've seen a few different potential solutions but most of them are in HANA Studio or involve dynamic SQL generation.
I'm putting the SQL into Tableau so those are both off the table.
...sum("StockInQualityInspection") as in_quality,
sum("StockInTransit") as its
from "_SYS_BIC"."stream.models.marketing.poly/InventoryQuery" ('PLACEHOLDER' = ('$$IPCurrentYear$$', '2018'))
where "StockValuatedUnrestrictedUse" <> 0 or "StockInQualityInspection" <> 0 or "StockInTransit" <> 0
group by case when "ReceivingPlant" is null then "Plant" else "ReceivingPlant" end,
case....
Remove the parameters input of your CV
Add this expression: year(now())
If you don't have access to manipulate the CV, into your query use:
('PLACEHOLDER' = ('$$IPCurrentYear$$', select year(now()) from DUMMY))
Regards
while placing a query is not permitted, you can pass a parameter as following
do begin
declare lv_param nvarchar(100);
select max('some_date')
into lv_param
from dummy /*your_table*/;
select *
from "_SYS_BIC"."path.to.your.view/CV_TEST" (
PLACEHOLDER."$$P_DUMMY$$" => :lv_param
);
end;

I have this Stored Procedure, where i need to check if #DateChk == 1, THEN i want to add a WHERE-clause to the SQL statement in the SP. If its 0, there should not be any WHERE-clause.
How do i script such function? In a program i could just build in the string to pass to the server, but i have not found any way to do this in the SQL server.
SELECT dateDay, SUM(nok) as NOK, SUM(ok) as OK, (SUM(ok) + SUM(nok)) as 'Total'
FROM #st
SELECT CASE #DateChk
WHEN 1: WHERE dateDay BETWEEN '2016-08-01' AND '2016-08-31'
Something like this, if #DateChk = 1, the WHERE should be added, else fetch all records.
You can modify your condition like this:
SELECT dateDay, SUM(nok) as NOK, SUM(ok) as OK, (SUM(ok) + SUM(nok)) as 'Total'
FROM #st
WHERE
(#DateChk = 1 and (dateDay BETWEEN '2016-08-01' AND '2016-08-31'))
or #DateChk = 0
And it will exactly match your desired behaviour: condition on dateDay will be applied only when #DateChk = 1.
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.
I have an MS-SQL table, with a column titled 'ImportCount'.
Data in this column follows the below format:
ImportCount
[Schedules] 1376 schedule items imported from location H:\FOLDERA\AA\XX...
[Schedules] 10201 schedule items imported from location H:\FOLDERZZ\PERS\YY...
[Schedules] 999 schedule items imported from location R:\PERS\FOLDERA\AA\XX...
[Schedules] 21 schedule items imported from location H:\FOLDERA\MM\2014ZZ...
What I would like to do is extract that numerical portion of the data (which varies in length), but am struggling to get the right result. Would appreciate any help on this!
Thanks.
Try
select left(ImportCount, patindex('%[^0-9]%', ImportCount+'.') - 1)
select SUBSTRING(ImportCount,13,patindex('% schedule items%',ImportCount)-13) from table name
Try this..You can declare it as a SQL function also.
DECLARE #intText INT
DECLARE #textAplhaNumeric varchar(100)
set #textAplhaNumeric = '1376 schedule items imported from location'
SET #intText = PATINDEX('%[^0-9]%', #textAplhaNumeric)
BEGIN
WHILE #intText > 0
BEGIN
SET #textAplhaNumeric = STUFF(#textAplhaNumeric, #intText, 1, '' )
SET #intText = PATINDEX('%[^0-9]%', #textAplhaNumeric)
END
END
Select #textAplhaNumeric //output is 1376
It will work in case of NULL or empty values.
Please try:
SELECT LEFT(Val,PATINDEX('%[^0-9]%', Val+'a')-1) from(
SELECT
STUFF(ImportCount, 1, PATINDEX('%[0-9]%', ImportCount)-1, '') Val
FROM YourTable
