if else ladder

Hi All



I am working on a project in which i need to record a keyword test and then i have to generate script from the same [jscript].



Requirement is -

I need to check for a particular existence lets example a table in the database , database opens in the same application , if the table exists then i need to proceed with some other implementations and if it doesnt then it simply needs to be created and perform some other steps.



Please guide me how to use if... else ladder both in keyword test and in script file too, and how to make use of it in case of objects like for existence of table, what should i need to perform







Thanks in advance
