Hi
I want to generate random integer numbers in Teradata.
In SQL, we have random function rand(), but it gives only the whole number between 0 and 1.
1. Like wise do we have any function to generate random numbers in Teradata?
2. And also similarly i want to select random records from a set of records in a table.
Does any one help me to do the above two tasks?
Thanks
Dileep

Hello,
You can use following for random number:
- SELECT Random("min value", "max value"); e.g.: SELECT Random(0, 10);
For selecting random rows, you can use:
- SELECT * from Table1 Sample 10;
HTH.

Yes, you could have tested it yourself as well. :)
For verification, try this several times: "SELECT Random(1, 2);"
