Example 1 with OrExpr

use of org.eclipse.scout.rt.server.jdbc.parsers.sql.SqlParserToken.OrExpr in project scout.rt by eclipse.

the class SqlParser method parseListExpr.

private ListExpr parseListExpr(List<IToken> list, ParseContext ctx) {
    // OrExpr (ListSeparator OrExpr)*
    ParseStep lock = ctx.checkAndAdd("ListExpr", list);
    if (lock == null) {
        return null;
    }
    try {
        OrExpr oe = parseOrExpr(list, ctx);
        if (oe == null) {
            return null;
        }
        ListExpr le = new ListExpr();
        le.addChild(oe);
        ListSeparator ls = null;
        while ((ls = removeToken(list, ListSeparator.class)) != null && (oe = parseOrExpr(list, ctx)) != null) {
            le.addChild(ls);
            le.addChild(oe);
        }
        // restore incomplete
