------------------------------------
Fix Version/s: (was: 1.8)
2.0
> 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: 1.5.0.final, 1.6
> Reporter: Edward Kaganovich
> Labels: SQL, UDF
> Fix For: 2.0
>
>
> 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
> public static 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}
