Example 1 with RowValueConstructorParseNode

use of org.apache.phoenix.parse.RowValueConstructorParseNode in project phoenix by apache.

the class ExpressionCompiler method visitLeave.

    ParseNode rhsNode = node.getChildren().get(1);
    Expression lhsExpr = children.get(0);

    CompareOp op = node.getFilterOp();
    if (lhsNode instanceof RowValueConstructorParseNode && rhsNode instanceof RowValueConstructorParseNode) {
        int i = 0;
        for (; i < Math.min(lhsExpr.getChildren().size(), rhsExpr.getChildren().size()); i++) {
            addBindParamMetaData(lhsNode.getChildren().get(i), rhsNode.getChildren().get(i), lhsExpr.getChildren().get(i), rhsExpr.getChildren().get(i));

Example 2 with RowValueConstructorParseNode

use of org.apache.phoenix.parse.RowValueConstructorParseNode in project phoenix by apache.

the class SubqueryRewriter method getJoinConditionNode.

    List<ParseNode> lhsNodes;
    if (lhs instanceof RowValueConstructorParseNode) {
        lhsNodes = ((RowValueConstructorParseNode) lhs).getChildren();

    if (lhsNodes.size() != (rhs.size() - 1))
        throw new SQLExceptionInfo.Builder(SQLExceptionCode.SUBQUERY_RETURNS_DIFFERENT_NUMBER_OF_FIELDS).build().buildException();
    int count = lhsNodes.size();
