When I used Loadrunner, it can read data from a csv file. As we know , csv file is separated by a comma.
The question is, if the parameter in csv has comma itself, the string will be separated to several segments. That is not I want to get.
How can we get the original data with comma in it?
回答1:
When data has a comma, use an escape character to store the data in the parameter. For example, if the name is 'Smith, John', it can be stored as Smith\, John in the Loadrunner data file.

When you save a file in Excel that has commas in the actual cell data, the whole cell will be inside two " characters. Also it seems that cells with a space in them are inside " chars.
Example
ColA,ColB,"ColC with a , inside",ColD,ColE

The answer to the question is that perhaps the easiest way to do deal with , separators is to change the separator to a ; character. This is also a valid separator in CSV files.
Then the example would be:
ColA;ColB;"ColC with a , inside";ColD;ColE

Maybe the right way is to use C functions to read data from the file (for example fopen/fread)? When you have read it you be able to use "strchr" to find first quotes char and second quotes char. All in that interval would be a value, and it doesn't matter if comma is inside. For the documentation about fopen, fread,strchr, you could refer to the HP or C function references. Hope this will help you.

Assuming you are reading from a data file for the parameters, just use a custom seperator. Comma is the default, but you can define it to be whatever you want. Whenever I have a comma in the variable data I tend to use a pipe symbol, '|' as a way to distinguish the columns of data in the data file.
Examine your parameter dialog carefully and you will see where to make the change.
