> If table contains only keys (e.g. relationship table) then returned query
> contains empty update fields and resulting syntax is incorrect.
> Consider the following example:
> org.apache.ignite.cache.store.jdbc.dialect.OracleDialect#mergeQuery accepts
> key and val collections. The problem is relevant if val collection is empty.
> {code:java}
> return String.format("MERGE INTO %s t" +
> " USING (SELECT %s FROM dual) v" +
> " ON %s" +
> " WHEN MATCHED THEN" +
> " UPDATE SET %s" +
> " WHEN NOT MATCHED THEN" +
> " INSERT (%s) VALUES (%s)", fullTblName, selCols, match, setCols,
> colsLst, valuesCols);
> {code}
