I am trying to use clojure neocons to perform a cypher query where I need to use a variable placeholder for the label:
(def node-query "MATCH (n:{_nodetype})
RETURN n;")
I am getting an error when I add {_nodetype} but no error when I remove {_nodetype}
"Invalid input '{': expected whitespace or a label name (line 1, column 10 (offset: 9))\\n\\\"MATCH (n:{_nodetype})\\\"\\n ^\",\n \"exception\"...
Here is my call to tquery:
(cy/tquery conn node-query {:_nodeid _nodeid :_nodetype "Folder"})
What is the cypher / neocons syntax to MATCH by label with a variable?
I am very grateful for help you could suggest.
You cannot parameterize a label (or a relationship type). The rationale for this is that a different parameter value might result in a completely different query plan. Internally the query plan is cached with the query string.
For now just do string concatenation in Clojure to have "semi-dynamic" labels or relationship types.

how can i remove (only) the "XX-XX-XXXXX_" Part in certain values of a column in SSIS but WITHOUT affecting values that doesn't have this format? For example "21-05-2022_12345678" = "12345678" but the other values i don't want them affected. This are just examples of many rows from this column so i want only the ones that have this format to be affected.
SELECT REVERSE(substring(REVERSE('09-03-2022_13481330'),0,CHARINDEX('_',REVERSE('09-03-2022_13481330'),0)))
result
13481330
but this also affects others values.Also this is in ssms not ssis because i am not sure how to transform this expression in ssis code.
Update : Corrected code in SSIS goes as following:
(FINDSTRING(IDENTIFIER,"__-__-____[_]",1) == 1) ? SUBSTRING(IIDENTIFIER,12,LEN(IDENTIFIER) - 11) : IDENTIFIER
Do you have access to the SQL source? You can do this on the sql by using a LIKE and crafting a match pattern using the single char wildcard _ please see below example
DECLARE #Value VARCHAR(50) = '09-03-2022_13481330'
SELECT CASE WHEN #Value LIKE '__-__-____[_]%' THEN
SUBSTRING(#Value,12,LEN(#Value)-11) ELSE #Value END
Please see the Microsoft Documentation on LIKE and using single char wildcards
If you don't have access to the source SQL it gets a bit more tricky as you might need to use regex in a script task or maybe there is a expression you can apply
I'm brand new to using PBI but as far as I can tell, I should be able to substitute a parameter as part of a Direct Query in place of a hard-coded variable...ie
let
Source = Sql.Database("NAMEOFDB", "CMUtility", [Query="sp_get_residentsinfo "& home_name]),.....
instead of
let
Source = Sql.Database("NAMEOFDB", "CMUtility", [Query="sp_get_residentsinfo 'NAME OF HOME'"]),...
However, the parameter-included version just says
DataSource.Error: Microsoft SQL: Incorrect syntax near 'House'.
Details:
DataSourceKind=SQL
DataSourcePath=NAMEOFDB;CMUtility
Message=Incorrect syntax near 'House'.
Number=102
Class=15
"House" is the currently - assigned last word of the home_name variable. What have I done wrong?
PS - I have surmised that I shouldn't need the extra & at the end of the parameter, as I'm not adding anything else to the query, but even with both &s it still doesn't work.
The type of your parameters is text. In SQL, text literals must be quoted, i.e. sp_get_residentsinfo 'NAME OF HOME', but the statement build by you is sp_get_residentsinfo NAME OF HOME.
You should use Text.Replace to escape single quotes in the parameter's value and append a quote before and after it.
I have a series of values in Tableau that are long strings intermixed with letters and numbers. I am unable to control the data output, but would like to parse the names from these strings. They follow the following format:
Potato 1TByte 4.5 NFA
Board 256GByte 553 NCA
Launch 4 512GByte 4.5 NFA
Launch 4S 512GByte 4.5 NCA
From each of these, I am attempting to capture the following:
"Potato"
"Board"
"Launch 4"
"Launch 4S"
Each string follows the same format: the name, followed by size, followed by some extra information we don't really care about.
I've tried to put together some text parsing strings, but am coming up short, and am still trying to learn regular expressions.
The Tableau calculated field I was trying to work with was something like the following:
LEFT([String], FIND([String], "Byte") - 2)
The issue is that the text and numbers preceding Byte can be anywhere from 4 to 2 characters and I need a way to identify the length of that.
Any help would be greatly appreciated!
One option which uses a regex replacement:
REGEXP_REPLACE('Launch 4 512GByte 4.5 NFA', ' \d+[A-Z]Byte .*$', '')
This strips off everything from the Byte term to the right, leaving us with only the product name.
You could try the following - this seems to work - Screenshot of Tableau output. Find below the formulas for the various derived columns you see in the screenshot (Your source column is called [Name])
Step1 = LEFT([Name],FIND([Name],"Byte")-1)
Step2 = LEN([Step1])-LEN(REPLACE([Step1]," ",""))
Step3 = FINDNTH([Step1]," ",[Step2])
Step4 = LEFT([Step1],[Step3]-1)
And of course you can nest all these in a single calculated field - kept them as separate columns for easier understanding
I am using HiveQL to work with millions of rows of domain name text data stored in HDFS. The following is a hand-selected subset to illustrate lexical diversity. There are duplicate entries.
dnsvm.mgmtsubnet.mgmtvcn.oraclevcn.com.
mgmtsubnet.mgmtvcn.oraclevcn.com.
asdf.mgmtvcn.oraclevcn.com.
dnsvm.mgmtsubnet.mgmtvcn.oraclevcn.com.
localhost.
a.localhost.
img.pulsemgr.com.
36.136.154.156.in-addr.arpa.
accounts.spotify.com.
_dmarc.ixia-devops.com.
&eventtype=close&reason=4&duration=35.
&eventtype=close&reason=3&duration=10336.
I am trying to get a count of # of rows based on the last two levels of the domain, where sometimes the 2nd level is absent (i.e. localhost.). For example:
domain_root count
oraclevcn.com. 4
localhost. 1
a.localhost. 1
pulsemgr.com. 1
in-addr.arpa. 1
spotify.com. 1
ixia-devops.com 1
It would be nice to also see how to filter out domains 2nd level is absent.
I am not sure where to start. I have seen use of the SPLIT() function, but that may not be robust since there could be many levels to a domain name, for example: a.b.c.d.e.f.g.h.i etc.
Any ideas are implementations are appreciated.
Below would be the query with regexp_extract.
select domain_root, count(*) from (select regexp_extract('dnsvm.mgmtsubnet.mgmtvcn.oraclevcn.com.', '[A-Za-z0-9-]+\.[A-Za-z0-9-]+\.$', 0) as domain_root from table) A group by A.domain_root -- replace first argument with column name
regex will extract for domain root with Alphanumeric and special character '-'
hope this helps.
I have this line in my query:
IF (TEST_DESC CONTAINING 'OPEN') THEN TEST_DESC = 'OPEN';
but that is not working. Firebird says Can't Prepare , because query is empty,
when I remove the ; it says Token unknown - line 8, column 10.
(.
I want to use IF ELSE to look if the TEST_DESC field contains OPEN, if it has, it will output the word OPEN in the field. The TEST_DESC field contains SCL_OPEN I only want to show the OPEN. And the other one is that the other value contains DRV_SHORT, and I want to show SHORT only.
Thanks in advance!
IF/THEN/ELSE is a PSQL construct.
For a plain SQL query, which I infer you're using from your syntax error, use a CASE statement:
...
CASE
WHEN TEST_DESC LIKE '%OPEN%'
THEN 'OPEN'
WHEN TEST_DESC LIKE '%SHORT%'
THEN 'SHORT'
ELSE 'UNKNOWN'
END
...
There is also an IIF() function with approximately the syntax you want: IIF(TEST_DESC CONTAINING 'FOO', 'FOO', 'NO FOO').
