I have folowing data set in my calculation view:
And Im trying create two additional calculated columns for the key ''SAPClient Warehouse TU_NUM":
Column should return ''X", if ((TXT04='CHKO') and (STATUS_VALUE='X')) AND ((TXT04='CHKI') and (STATUS_VALUE='X'))
Column should return "X", if ((TXT04='CHKO') and (STATUS_VALUE=' ')) AND ((TXT04='CHKI') and (STATUS_VALUE='X'))
When I try to create the first column I'm using following code:
if("TXT04"='CHKO',if("STATUS_VALUE"='X', 'X',' '),' ') and if("TXT04"='CHKI',if("STATUS_VALUE"='X', 'X',' '),' ')
But get following syntax error:
Could you give me any tipps about how I can solve my problem in a better way?
Would apreciate any help.
Thanks and BR.
Function IF returns a string value in your expression so there's no AND operator defined on strings (more precisely AND is a function, as you can see via trace).
But I think there's a typo in your code since (A and B) and (C and D) equals to A and B and C and D, and you try to "AND" TXT04='CHKO' and TXT04='CHKI' which obviously is FALSE.
If you have only two values, then you can use a single IF if(<1'st group of conditions>, 'X', '') and group all your conditions accordingly. If you have third value (except 'X' and ''), then replace '' in the snippet with the second if. For more than two output values I prefer case statement.

I am trying to extract only the numeric values from a column that contains cells that are exclusively numbers, and cells that are exclusively letter values, so that I can multiply the column with another that contains only numeric values. I have tried
SELECT trim(INTENT_VOLUME)
from A
WHERE ISNUMERIC(INTENTVOLUME)
and also
SELECT trim(INTENT_VOLUME)
from A
WHERE ISNUMERIC(INTENTVOLUME) = 1
and neither works. I get the error Function ISNUMERIC(VARCHAR) does not exist. Can someone advise? Thank you!
It highly depends on DBMS.
in SqlServer you have a limited built-in features to do it, so the next query may not work with all variants of your data:
select CAST(INTENT_VOLUME AS DECIMAL(10, 4))
from A
where INTENT_VOLUME LIKE '%[0-9.-]%'
and INTENT_VOLUME NOT LIKE '%[^0-9.-]%';
In Oracle you can use regex in a normal way:
select to_number(INTENT_VOLUME)
from A
where REGEXP_LIKE(INTENT_VOLUME,'^[-+]?[0-9]+(\.[0-9]+)?$');
MySQL DBMS has also built-in regex
Try this, which tests if that text value can be cast as numeric...
select intent_volume
from a
where (intent_volume ~ '^([0-9]+[.]?[0-9]*|[.][0-9]+)$') = 't'
I am trying to use a simple Translate function to replace "-" in a 23 digit string. The example of one such string is "1049477-1623095-2412303" The expected outcome of my query should be 104947716230952412303
The list of all "1049477-1623095-2412303" is present in a single column "table1". The name of the column is "data"
My query is
Select TRANSLATE(t.data, '-', '')
from table1 as t
However, it is returning 104947716230952000000 as the output.
At first, I thought it is an overflow error since the resulting integer is 20 digit so I also tried to use following
SELECT CAST(TRANSLATE(t.data,'-','') AS VARCHAR)
from table1 as t
but this is not working as well.
Please suggest a way so that I could have my desirable output
This is too long for a comment.
This code:
select translate('1049477-1623095-2412303', '-', '')
is going to return:
'104947716230952412303'
The return value is a string, not a number.
There is no way that it can return '104947716230952000000'. I could only imagine that happening if somehow the value is being converted to a numeric or bigint type.
Try regexp_replace()
Taking your own example, execute:
select regexp_replace('[string / column_name]','-');
It can be achieve RPAD try below code.
SELECT RPAD(TRANSLATE(CAST(t.data as VARCHAR),'-','') ,20,'00000000000000000000')
In my report query I have a where clause that needs to be replaced dynamically based on the data chosen in the front end.
The query is something like :
where ?=?
I already have a code to replace the value - I created report parameter and linked to the value ? in the query.
Example:
where name=?
Any value of name that comes from front end replaces the ? in the where clause - this works fine.
But now I need to replace the entire clause (where ?=?). Should I create two parameters and link them to both the '?' ?
No, unfortunately most database engines do not allow to use a query parameter for handling a dynamic column name. This is for security considerations.
So you need to keep an arbitrary column name in the query:
where name=?
And then in "beforeOpen" script of the dataset replace 'name' with a report parameter value:
this.queryText=this.queryText.replace("name",params["myparameter"].value);
To prevent SQLIA i recommend to test the value of the parameter in this script. There are many ways to do this but a white list is the strongest test, for example:
var column=params["myparameter"].value;
if (column=="name" || column=="id" || column=="account" || column=="mycolumnname"){
this.queryText=this.queryText.replace("name",column);
}
In addition to Dominique's answer and your comment, then you'll just need a slightly more advanced logic.
For example, you could name your dynamic column-name-value pairs (column1, value1), (column2, value2) and so on. In the static text of the query, make sure to have bind variables for value1, value2 and so on (for example, with Oracle SQL, using the syntax
with params as (
select :value1 as value1,
:value2 as value2 ...
from dual
)
select ...
from params, my_table
where 1=1
and ... static conditions....
Then, in the beforeOpen script, append conditions to the query text in a loop as needed (the loop left as an exercise to the reader, and don't forget checking the column names for security reasons!):
this.queryText += " and " + column_name[i] + "= params.value" + i;
This way you can still use bind variables for the comparison values.
I am working with a table that contains two versions of stored information. To simplify it, one column contains the old description of a file run while another column contains the updated standard for displaying ran files. It gets more complicated in that the older column can have multiple standards within itself. The table:
Old Column New Column
Desc: LGX/101/rpt null
null Home
Print: LGX/234/rpt null
null Print
null Page
I need to combine the two columns into one, but I also need to delete the "Print: " and "Desc: " string from the beginning of the old column values. Any suggestions? Let me know if/when I'm forgetting something you need to know!
(I am writing in Cache SQL, but I'd just like a general approach to my problem, I can figure out the specifics past that.)
EDIT: the condition is that if substr(oldcol,1,5) = 'desc: ' then substr(oldcol,6)
else if substr(oldcol,1,6) = 'print: ' then substr(oldcol,7) etc. So as to take out the "desc: " and the "print: " to sanitize the data somewhat.
EDIT2: I want to make the table look like this:
Col
LGX/101/rpt
Home
LGX/234/rpt
Print
Page
It's difficult to understand what you are looking for exactly. Does the above represent before/after, or both columns that need combining/merging.
My guess is that COALESCE might be able to help you. It takes a bunch of parameters and returns the first non NULL.
It looks like you're wanting to grab values from new if old is NULL and old if new is null. To do that you can use a case statement in your SQL. I know CASE statements are supported by MySQL, I'm not sure if they'll help you here.
SELECT (CASE WHEN old_col IS NULL THEN new_col ELSE old_col END) as val FROM table_name
This will grab new_col if old_col is NULL, otherwise it will grab old_col.
You can remove the Print: and Desc: by using a combination of CharIndex and Substring functions. Here it goes
SELECT CASE WHEN CHARINDEX(':',COALESCE(OldCol,NewCol)) > 0 THEN
SUBSTRING(COALESCE(OldCol,NewCol),CHARINDEX(':',COALESCE(OldCol,NewCol))+1,8000)
ELSE
COALESCE(OldCol,NewCol)
END AS Newcolvalue
FROM [SchemaName].[TableName]
The Charindex gives the position of the character/string you are searching for.
So you get the position of ":" in the computed column(Coalesce part) and pass that value to the substring function. Then add +1 to the position which indicates the substring function to get the part after the ":". Now you have a string without "Desc:" and "Print:".
Hope this helps.
I am using the LIST function to create a ';' delimited list of values. The type is numeric (19,2). For some reason the precision appears to be ignored when using the list function. When performing a simple select on this column the values look good, ie "12.00". However, if I use a LIST() my results are of format "12.000000"
This is my LIST usage:
LIST(case when tblWOService.PricePerVehicle is null then ' ' else CONVERT(decimal(19,2),tblWOService.PricePerVehicle end,';')
The CONVERT does not change the result. Any ideas?
Thanks!
Have you tried explicitly converting your empty string?
LIST(
case when tblWOService.PricePerVehicle is null then CONVERT(decimal(19,2),' ')
else CONVERT(decimal(19,2),tblWOService.PricePerVehicle) end,';'
)
I've run into a similar datatype issue with CASE statements in T-SQL.
