classConcatenationRule
final class ConcatenationRule
implements RewriteRuleDefault SQL mode scans || as OR2_SYM; the OR_OR_SYM production constructs Item_func_concat. Preserve its operands and precedence by expressing that production as a native function call.
Methods§
public function rewrite(TerminalSequence $sequence): TerminalSequenceRewrites innermost concatenations first, retaining the identities of both operand subtrees.
Parameters
$sequence | TerminalSequence |
