Summary: QuerySqlFunction methods with Object type var args do not work Key: IGNITE-3608 URL: https://issues.apache.org/jira/browse/IGNITE-3608 Project: Ignite Issue Type: Bug Components: cache, SQL Affects Versions: 1.6, 1.5.0.final Reporter: Edward Kaganovich We often use interactive sql consoles to query caches. Several field values as well as _key in caches are stored as objects. To support queries by these fields we have registered a generic UDF that should let us instantiate certain types: {code} @QuerySqlFunction Object t(String clz, Object... ctorArgs) throws Exception { Class<?> c = Class.forName(keyClz); Class<?>[] argTypes = new Class[ctorArgs.length]; for (int i=0; i < ctorArgs.length; i++) { argTypes[i] = ctorArgs[i].getClass(); } Constructor<?> ctor = c.getConstructor(argTypes); return ctor.newInstance(ctorArgs); } {code} Unfortunately Ignite fails to find and execute this function for the following SQL: {color:blue}select t('java.lang.String', 'key20')){color}{color:red} <- Fails{color} However, there is no problems with this function: {code} @QuerySqlFunction public static Object t1(String clz, String... ctorArgs) throws Exception { return t(clz, ctorArgs); } {code} {color:blue}select t1('java.lang.String', 'key20')){color}{color:green} <- Works as expected{color} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
