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;

You need to recreate your query and make sure to follow the flow of the clauses properly, please check the next two links to get a better understanding :
[ORA-00936: missing expression tips]
How do I address this ORA-00936 error?
Answer: The Oracle oerr utility notes this about the ORA-00936 error:
ORA-00936 missing expression
Cause: A required part of a clause or expression has been omitted. For example, a SELECT statement may have been entered without a list of columns or expressions or with an incomplete expression. This message is also issued in cases where a reserved word is misused, as in SELECT TABLE.
Action: Check the statement syntax and specify the missing component.
The ORA-00936 happens most frequently:
1 - When you forget list of the column names in your SELECT statement.
2. When you omit the FROM clause of the SQL statement.

I hope this can help you.
You cannot use a simple select query like this. You have to use a PL/SQL block like below -
DECLARE NUM_CNT NUMBER := 0;
BEGIN
SELECT Count(1)
INTO NUM_CNT
FROM wf_item_activity_statuses_v t
WHERE t.activity_label IN ('WAITING_DISB_REQ',
'LOG_DDE',
'LOG_SENDBACK_DDE')
AND t.item_key IN(SELECT r.i_item_key
FROM wf_t_item_xref r
WHERE r.sz_appl_uniqueid = '20400000988');
IF NUM_CNT = 0 THEN
delete
from t_col_val_document_uploaded p
WHERE p.sz_application_no = '20400000988'
AND p.sz_collateral_id = 'PROP000000000PRO1701'
AND p.i_item_key = '648197'
AND p.i_document_srno = '27';
ELSIF NUM_CNT = 1 THEN
DELETE
FROM t_col_val_document_uploaded p
WHERE p.sz_application_no = '20400000988'
AND p.sz_collateral_id = 'PROP000000000PRO1701'
AND p.i_document_srno = '28' )
END IF;
END;
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 believe that the cursor used in this code is the reason for some major performance issues, however I am new to TSQL.
Following script runs on SQL SERVER 2008. I am trying to redo it so I use JOIN statements instead, however I have not been able to do so successfully.
DECLARE AIRAMSDET CURSOR FOR
SELECT BILL, RECIEPT, NAME
FROM Client_Table
WHERE IsProcessed = 1
AND TYPE IN ('Sub','First_Time','Old') AND LEN(BILL) > 1
OPEN AIRAMSDET
FETCH AIRAMSDET into #VARBILL, #VARRECIEPT, #VARNAME
WHILE ##Fetch_Status = 0
BEGIN
UPDATE archieve
SET entry = left(#VARBILL + '- '+ #VARNAME)
WHERE archiveID = #VARBILL
END
It should be something like following
UPDATE ARCHIEVE
SET ENTRY = CT.BILL + '-' + CT.NAME
FROM CLIENT_TABLE CT
WHERE
ARCHIEVE.ARCHIVEID = CT.BILL
AND CT.ISPROCESSED = 1
AND CT.TYPE IN ('Sub','First_Time','Old') AND LEN(BILL) > 1
I have not included LEFT() as its use in your query wasn't very clear. Left takes an integer_expression as its second parameter while you are passing ##VARNAME which most likely is a VARCHAR. Please add that as you deem fit.
First, I have read about similar posts and have read the comments that this isn't an ideal solution and I get it but the boss (ie client) wants it this way. The parameters are as follows (for various reasons too bizarre to go into but trust me):
1. SQL Server Mgmt Studio 2016
2. NO parameters or pass throughs or temp tables. All has to be within contained code.
So here we go:
I need to create column headings that reflect dates:
1. Current date
2. Most recent quarter end prior to current date
3. Most recent quarter end prior to #2
4. Most recent quarter end prior to #3
5. Most recent quarter end prior to #4
6. Most recent quarter end prior to #5
So if using today's date, my column names would be as follows
12/18/2016 9/30/2016 6/30/2016 3/31/2016 12/31/2016 9/30/2015
I can easily do it in SAS but can't in SQL given the requirements stated above.
Help please with same code.
Thank you
Paula
Seems like a long way to go for something which really belongs in the presentation layer. That said, consider the following:
Let's assume you maintain a naming convention for your calculated fields, for example [CurrentDay], [QtrMinus1], [QtrMinus2], [QtrMinus3], [QtrMinus4],[QtrMinus5]. Then we can wrap your complicated query in some dynamic SQL.
Just as an illustration, let's assume your current query results looks like this
After the "wrap", the results will then look like so:
The code - Since you did NOT exclude Dynamic SQL.
Declare #S varchar(max)='
Select [CustName]
,['+convert(varchar(10),GetDate(),101)+'] = [CurrentDay]
,['+Convert(varchar(10),EOMonth(DateFromParts(Year(DateAdd(QQ,-1,GetDate())),DatePart(QQ,DateAdd(QQ,-1,GetDate()))*3,1)),101)+'] = [QtrMinus1]
,['+Convert(varchar(10),EOMonth(DateFromParts(Year(DateAdd(QQ,-2,GetDate())),DatePart(QQ,DateAdd(QQ,-2,GetDate()))*3,1)),101)+'] = [QtrMinus2]
,['+Convert(varchar(10),EOMonth(DateFromParts(Year(DateAdd(QQ,-3,GetDate())),DatePart(QQ,DateAdd(QQ,-3,GetDate()))*3,1)),101)+'] = [QtrMinus3]
,['+Convert(varchar(10),EOMonth(DateFromParts(Year(DateAdd(QQ,-4,GetDate())),DatePart(QQ,DateAdd(QQ,-4,GetDate()))*3,1)),101)+'] = [QtrMinus4]
,['+Convert(varchar(10),EOMonth(DateFromParts(Year(DateAdd(QQ,-5,GetDate())),DatePart(QQ,DateAdd(QQ,-5,GetDate()))*3,1)),101)+'] = [QtrMinus5]
From (
-- Your Complicated Query --
Select * from YourTable
) A
'
Exec(#S)
If it helps the visualization, the generated SQL is as follows:
Select [CustName]
,[12/18/2016] = [CurrentDay]
,[09/30/2016] = [QtrMinus1]
,[06/30/2016] = [QtrMinus2]
,[03/31/2016] = [QtrMinus3]
,[12/31/2015] = [QtrMinus4]
,[09/30/2015] = [QtrMinus5]
From (
-- Your Complicated Query --
Select * from YourTable
) A
Here is one way using dynamic query
DECLARE #prior_quarters INT = 4,
#int INT =1,
#col_list VARCHAR(max)=Quotename(CONVERT(VARCHAR(20), Getdate(), 101))
WHILE #int <= #prior_quarters
BEGIN
SELECT #col_list += Concat(',', Quotename(CONVERT(VARCHAR(20), Eomonth(Getdate(), ( ( ( ( Month(Getdate()) - 1 ) % 3 ) + 1 ) * -1 ) * #int), 101)))
SET #int+=1
END
--SELECT #col_list -- for debugging
EXEC ('select '+#col_list+' from yourtable')
I'm trying to extract a portion of a value out of a database column using SQL server.
The example below works in a simple context with a varchar field. The result is: &kickstart& which is what I want.
I now want to do the same when retrieving a column from the database.
But SQL does not like what I am doing. I'm thinking it is something easy that I am not seeing.
Declare #FileName varchar(20) = '&kickstart&.cfg'
Declare #StartPos integer = 0
Declare #FileNameNoExt varchar(20)
SELECT #FileNameNoExt = Left(#FileName,( (charindex('.', #FileName, 0)) - 1))
SELECT #FileNameNoExt
Here is the SQL statement that I can't seem to get to work for me:
Declare #FileNameNoExt as varchar(20)
SELECT
i.InstallFileType AS InstallFileType,
o.OSlabel AS OSLabel,
SELECT #FileNameNoExt = (LEFT(oi.FIleName,( (charindex('.', oi.FIleName, 0) ) - 1) )) AS FileNameNoExt,
oi.FIleName AS FIleName
FROM
dbo.OperatingSystemInstallFiles oi
JOIN dbo.InstallFileTypes i ON oi.InstallFileTypeId = i.InstallFileTypeId
JOIN dbo.OperatingSystems o ON oi.OperatingSystemId = o.OperatingSystemId
Why do you need the variable at all? What's wrong with:
SELECT
i.InstallFileType AS InstallFileType,
o.OSlabel AS OSLabel,
LEFT(oi.FIleName,( (charindex('.', oi.FIleName, 0) ) - 1) ) AS FileNameNoExt,
oi.FIleName AS FIleName
FROM
dbo.OperatingSystemInstallFiles oi
JOIN dbo.InstallFileTypes i ON oi.InstallFileTypeId = i.InstallFileTypeId
JOIN dbo.OperatingSystems o ON oi.OperatingSystemId = o.OperatingSystemId
You've put a SELECT inside another SELECT list without nesting, which is a syntax error in SQL Server.
You are also attempting to assign a variable while performing a data-retrieval operation. You can select all data to be shown, or all data into variables but not both at the same time.
When the two issues above are resolved, I think you may still run into issues when committing filenames into a variable which only allows 20 characters - but then I don't know anything about your dataset.
