Example

import { CreateRefineService } from 'mssqlrefine'

const refineService = CreateRefineService()
refineService.prepareWorldsAll('upper')

//build tokens in one iteration
const tokens1 = refineService.getTokens([
    `select a, /*comment*/, [b]+[c], 'string' as d`,
    `from mytable order by a --comment`
])

//build tokens in two iterations
const tokens2 = refineService.getTokens([
    `select a, /*comment*/, [b]+[c], 'string' as d`
])
tokens2.push(...refineService.getTokens([`from mytable order by a --comment`], tokens2))

//tokens1 and tokens2 are equal
console.log(tokens1)
console.log(tokens2)
