isLeafNode	`val isLeafNode: Boolean` Check if this expression is a leaf node in expression trees.
left	`val left: QuerySourceExpression` the left table.
right	`val right: QuerySourceExpression` the right table.
type	`val type: JoinType` the expression’s type.

Extension Functions

Name	Summary
eq	`infix fun <T : Any> T.eq( expr: ColumnDeclaring<T> ): BinaryExpression<Boolean>` Equal operator, translated to `=` in SQL.
neq	`infix fun <T : Any> T.neq( expr: ColumnDeclaring<T> ): BinaryExpression<Boolean>` Not-equal operator, translated to `<>` in SQL.
notEq	`infix fun <T : Any> T.notEq( expr: ColumnDeclaring<T> ): BinaryExpression<Boolean>` Not-equal operator, translated to `<>` in SQL.
