Example #2
Source File: ESActionFactory.java From elasticsearch-sql with Apache License 2.0 | 5 votes |
private static SQLExpr toSqlExpr(String sql) { SQLExprParser parser = new ElasticSqlExprParser(sql); //zhongshu-comment 这个SQLExprParser parser应该就是语法解析器 SQLExpr expr = parser.expr(); //zhongshu-comment 这个expr应该就是解析sql之后得到的AST了 //zhongshu-comment 调用parser.expr()方法解析完sql语句后,发现最后一个token不是End Of File的话,即该sql语句貌似是残缺的,可能是用户输入了一个未结束的sql if (parser.getLexer().token() != Token.EOF) { throw new ParserException("illegal sql expr : " + sql); } return expr; }
