Hi...

I have some data that contains a column with a URL field. Within the URL field's contents, there are several values that I need to be able to parse out.

I can only do this with SQL (i.e. cant write a function since I dont have permissions to register/execute).

Can anyone help?

Thanks!


Example of URL field data

WT.tz=-6&WT.bh=17&WT.ul=en-us&WT.cd=32&WT.sr=1280x720&WT.jo=Yes&WT.ti=Veda%20Spa%20at%20Hotel%20Monaco%20in%20Denver,%20Colorado&WT.js=Yes&WT.jv=1.3&WT.ct=lan&WT.hp=0&WT.bs=1263x1773&WT.fv=10.0&WT.slv=Unknown&WT.tv=9.3.0&WT.sp=KC-DMN&WT.dl=0&WT.ssl=0&WT.es=
Example of final format/output of data

->One column for every WT parameter and its corresponding value

WT.tz WT.bh WT.ul WT.cd WT.sr WT.jo WT.TI
6 17 en-us 32 1280x720 Yes Veda Spa at Hotel Monaco in Denver,Colorado

Check out POSITION and SUBSTRING.

Are the different WT-labels always in this order? If that's the case it may end up with something like [tt]
SELECT SUBSTRING(col FROM POSITION('WT.tz=' IN col) + 6
FOR POSITION('WT.bh=' IN col) -
POSITION('WT.tz=' IN col) - 7) AS "WT.tz",
SUBSTRING(col FROM POSITION('WT.bh=' IN col) + 6
FOR POSITION('WT.ul=' IN col) -
POSITION('WT.bh=' IN col) - 7) AS "WT.bh"
etc[/tt]

You may also want to use CAST to reduce the length of the selected values.

Hi JarlH,

Thanks for the snippet. When I tried to use, it gives me an error about a mismatched input around the "FROM" where it is expecting a ")" in the expression specification. From this, I have tried to add the additional parenthesis but still get an error. Sorry to be such a pain but can you review?

Thanks,

Tony

tony, the reason you're getting an error is likely because whatever database system you're using (which you didn't mention) doesn't support the ANSI SQL code that jarlh gave you

you do realize that you asked this question in the ANSI SQL forum, and not, for instance, in forum183

You could try the non-ansi
[tt]substring(arg1,arg2[,arg3])[/tt]
or
[tt]substr(arg1,arg2[,arg3])[/tt]
