How many records in a table?

Hi! Stupid question as this also depends on hardware but is there a limit on
how many rows I can have in a single MSSQL 2000 table? Table consists of six
int columns and has three indexes. Is like 10 Million or 100 Million
considered to be 'normal' or unrealistic?

Thanks very much for your thoughts!

MartinMartin,

It's actually limited ONLY by hardware (disk space). I wouldn't say that 10
or 100 million are anywhere near "unrealistic". Maybe 1 trillion would be
more like it!

how is top % filter used?

ok question was stupid i know. i still want to know how the filters work and an example for each filter option would be great. why can't all documentations be like msdn library? the built-in documentation shipping with reporting services is just too advanced for moi.The Top% filter works similar to the TopN filter. A TopN filter with filter value =10 would return the first 10 values of the dataset - regardless of the total number of rows in the dataset. A Top% filter with filter value =10 would return the first 10% of the total number of rows in the dataset.

-- Robert|||I asked the question because the expression i wrote did not work so thought there was something wrong with my syntax. I finally found out that the reporting services filter does not correctly evaluate datatypes other than strings. So I changed my filter expression to convert the vaule into string first and now they work no thanks to the guy writing documentation. This is a bug and it took me quite a while to figure it out.|||

The alternative is to make sure it takes the value as a numeric by preceeding it with an equal sign. Without this post I would have spent a long time trying to get this to work.
