Please help in understanding below regex.
Data:
396124436476092416,"Think about the life you livin but don't think so hard it hurts Life is truly a gift, but at the same it is a curse",Obey_Jony09
Regex for above data:
(",(?=([^\"]\"[^\"]\")[^\"]$)")
It is trying to group the nick wich made the quote, I guess.

I am new to SPARQL, I have observed that when I am using group_concate function and ORDER BY Clause together, it stops ordering. I don't know why its happening.
Please let me know the solution
Thanks in advance

I need help with two instances where I need to utilize Reguar Expressions.
In this example A18040500198 ARM88 I need to extract ARM88 and using the same example I need to extract A18040500198
Would anybody be able to help me with this. Thank you very much in advance.
"(A[0-9]*)|(ARM88))" would return both strings, but many others too.
If you need to only return exactly those two strings, use "(A18040500198)|(ARM88)"
More information on what you specifically want the RegEx to do would be useful.
I have a really simple problem:
Replace XX_FistName LastName (maybe dr. or phd anything trash) to firstname lastname
now i am using regexp replace:
trim(regexp_replace(lower(vhc.name),'xx_|dr|\.|\,|phd|jr','')
but this is really really slow...
can you give me some hint how can i replace this something faster? I have too much data to compare and do other functions on these data and it takes hours.
A reduced one.
trim(regexp_replace(lower(vhc.name),'xx_|[dj]r|[.,]|phd','')
Late response, but might help someone landing here just like me.
replace(table1.column_here, 'string_to_be_replaced', 'to_replace_with')
I'm new to MDX and I cannot get the ordering correct. I looked at references online and I think i sorted the query correctly, but the result of the query doesn't agree with me. Can anyone shed some light into what I'm not doing.
I have included a hypothetical example that is close to my problem.
The result of the query comes out without being sorted.
Any help is deeply appreciated.
Thanks
The 2nd argument to the Order()-function on your Rows-axis, must be the value or string to sort by. If you want to sort by the names of the SalespersonID-members, do something like this:
Order([Sales].[SalespersonID], [Sales].CURRENTMEMBER.MEMBER_NAME) on Rows
I am trying to understand sql recursive statements, but it is really hard for me. For example:

Also, see here - http://www.postgresql.org/docs/8.4/static/queries-with.html, where the steps of the recursive query evaluation are described.
The UNION ALL portion gets recursed until it returns no more records. I don't know if you can have multiple UNION ALL portions.
