Query Builder Class

[Oleg]

Hi

how can i create a Query Builder class!?

is meant:

val params: List[(Int, List[String), Boolean] = List(1, List("a", "b"), true)

if (params._3.size > 1) then

for{t <- Table1 if t.str inSet params._3

 ....

}

else (params._3.size == 1) then

for{t <- Table1 if t.str like params._3(0) + "%"

 ....

}

...

is ugly. How can i make following:

if (params._3.size > 1) then

condition = < t.str inSet params._3 >

 ....

}

else (params._3.size == 1) then

condition =  <t.str like params._3(0) + "%">

 ....

}

val q = for{t <- Table1 if condition

} yield t

do anyone have idea / suggestion!?

Best Regards

Oleg
