ColdFusion CFID CFTOKEN Get lastvisit timecreated from CGLOBAL

I had a recent need to get information of CFID & CFTOKEN to see how many records we have in our datasource for CDATA, CGLOBAL and also from which date i.e. Last Min date to Last Max date the CGLOBAL table has values for. So I wrote this short query and then finally i cast the column as datetime so we can sort by date otherwise the sort will occur by string.

select cast( substring(data, charindex('ts',data) + 4 , 19) as datetime) as 'lastvisit' ,
cast( substring(data, charindex('ts',data,charindex('ts',data)+4 ) + 4 , 19) as datetime) as 'timecreated', lvisit from cglobal

where charindex('ts',data) gets the first occurrence and len('2009-08-18 22:36:55') gives you an idea of how many characters you need to extract and turns out its 19 characters.

Hope this helps someone.

Hawks v/s PowerBuilders. July 23 2009. Match 13.

Just last night, I finished writing about Kareem from Dalcha. Today it was another Karim from Power Builders, who hit some crazy Afridi style sixes to guide Power Builders to a victory. The game was full of excitement and pressure. The Power Builders gave a complete team performance, much like their opponents, Hawks. Sagar won the toss and elected to bat first. The opening duo, Sashi and Bhavin started well. They put on 18 runs of the first 2 overs. Bhavin scored 16 and Sashi made 8. The Hawks went for their shots and were caught on the boundary. Satish of Power Builders was very impressive as He caught 3 catches in the deep. Vinay was playing well and was making the life difficult for fielders, especially at long on as the ball would turn twice or thrice before reaching the fielder. You all know who was standing there. :-). Vinay was caught on the boundary by an absolutely brilliant one handed catch by Harsha. Vinay top scored for Hawks with 22 runs and in the process, hit some beauti...
