Table A ANO fields with XXX | | XXX | | XXXX | | variable composition, variable is generated by A process of encryption, now numbering generate repeat, I'd like to have the serial number of repeat to regenerate, namely modifying repeating ANO=now ANO top X | | call variable generation process,

The building Lord said your specific, practical operation and your description is the same,

CodePudding user response:

The paper gives an example of data and expected results

reference 1st floor selling fruit net reply:

the original poster said your specific issues, the actual operation is the same, and your description

I write is not assembly, logic is probably so

Data such as
10360073070002992320
10360073070002992321
10360073070002992322
10360073070002992322
10360073070002992323
10360073070002992323
10360073070002992324
10360073070002992325
10360073070002992325



Have private 22.23.25, repeat, now need to modify,
Before 1036007307, after ten by calling a encryption method generates output parameters,
For example, want to get the results as follows:
10360073070002992320
10360073070002992321
10360073070002992322 or this also reset
1036007307 + reset number 1
10360073070002992323 or this also reset
1036007307 + reset number 2
10360073070002992324
10360073070002992325 or this also reset
1036007307 + reset number 3

I didn't write this way has a good way to
Declare
Temp varchar2 (4096)
The Begin
The Loop cycle (
Should be in duplicate data query to the circulation, this won't write)
Calls to generate number method f number temp;
Update a set a.a no=substr (a.a, 0, 10)//temp;
Commit;
End loop;
The End;
Probably is this meaning

CodePudding user response:

If so, you only have to intercept back ten group by then, having the count (*) & gt; 1 line

CodePudding user response:

Wrong is to change the data, you first find out one of the biggest value is how much, and then write a cursor detect duplicate data rowid (can use analysis function queries), then use the largest value + 1 update each cycle

refer to 7th floor sxq129601 response:

wrong is to change the data, you first find out one of the biggest value is how much, and then write a cursor data found to repeat the rowid (can use analysis function queries), then use the largest value + 1 update each cycle

no, don't understand

I write good, thanks man
