Examples with IntervalLiteral io.crate.sql.tree.IntervalLiteral used on opensource projects

Example 1 with IntervalLiteral

use of io.crate.sql.tree.IntervalLiteral in project crate by crate.

the class AstBuilder method visitIntervalLiteral.

@Override
public Node visitIntervalLiteral(SqlBaseParser.IntervalLiteralContext context) {
    IntervalLiteral.IntervalField startField = getIntervalFieldType((Token) context.from.getChild(0).getPayload());
    IntervalLiteral.IntervalField endField = null;
    if (context.to != null) {
        Token token = (Token) context.to.getChild(0).getPayload();
        endField = getIntervalFieldType(token);
    }
    if (endField != null) {
        if (startField.compareTo(endField) > 0) {
            throw new IllegalArgumentException("Startfield must be less significant than Endfield");
        }
    }
    IntervalLiteral.Sign sign = IntervalLiteral.Sign.PLUS;
    if (context.sign != null) {
        sign = getIntervalSign(context.sign);
    }
    return new IntervalLiteral(((StringLiteral) visit(context.stringLiteral())).getValue(), sign, startField, endField);
}
