operator fun <T> get(original: Column<T>): Column<T>

operator fun <T> get(original: Expression<T>): Expression<T>

open infix override fun innerJoin(otherTable: ColumnSet): Join

Creates an inner join relation with otherTable.

fun select(columns: List<Expression<*>>): Query

Creates a SELECT Query using a list of columns or expressions from this ColumnSet.

fun select(column: Expression<*>, vararg columns: Expression<*>): Query

Creates a SELECT Query by selecting either a single column, or a subset of columns, from this ColumnSet.

inline fun FieldSet.~~select~~(where: SqlExpressionBuilder.() -> Op<Boolean>): Query

fun FieldSet.~~select~~(where: Op<Boolean>): Query

fun FieldSet.selectAll(): Query

Creates a SELECT Query by selecting all columns from this ColumnSet.

selectAllBatched

fun FieldSet.~~selectAllBatched~~(batchSize: Int = 1000): Iterable<Iterable<ResultRow>>

fun FieldSet.~~selectBatched~~(batchSize: Int = 1000, where: SqlExpressionBuilder.() -> Op<Boolean>): Iterable<Iterable<ResultRow>>

fun ~~slice~~(columns: List<Expression<*>>): FieldSet
