即時得到以下錯誤:點燃查詢異常
Caused by: org.h2.jdbc.JdbcSQLException: Syntax error in SQL statement "SELECT
""standard_item_cache"".""STANDARDITEM""._KEY,
""standard_item_cache"".""STANDARDITEM""._VAL FROM
""standard_item_cache"".""STANDARDITEM"" WHERE ITEMID[*] == ? "; SQL statement:
SELECT "standard_item_cache"."STANDARDITEM"._KEY,
"standard_item_cache"."STANDARDITEM"._VAL FROM
"standard_item_cache"."STANDARDITEM" WHERE itemId == ? [42000-196]
當我試圖執行一個簡單的查詢:
String itemId = params.get(Params.PARAM_ITEM_ID);
SqlQuery<String, StandardItem> sql = new SqlQuery<>(StandardItem.class, "itemid == ?");
try (QueryCursor<Cache.Entry<String, StandardItem>> cursor = standardItemIgniteCache.query(sql.setArgs(itemId))) {
logger.info("publish standard items from cache");
for (Cache.Entry<String, StandardItem> entry : cursor) {
logger.info("publish standard item: " + entry.getValue().toString());
}
logger.info("publishing standard items from cache done");
cursor.close();
}
哪裏錯了嗎? Im doint完全像它在apache ignite中描述的例子:https://apacheignite.readme.io/v1.0/docs/cache-queries
