Executing query service manually using java script

[Asif]

Hi
I need to run query service manually because I need to run it only when certain condition becomes true
ex:
if (var1==1)
{
querySrc.execute({data:{where:{userName:"asif"}}});
}
something like this

Hello! Value of "where" parameter should be a string. Use codeif (var1==1)
{
querySrc.execute({data:{where:'{userName:"asif"}'}});
}/code
