Java : error in SQL syntax

Question

我正在尝试使用以下查询从数据库中检索信息:

 String Retrieve 
                    = "SELECT o.order_id , o.betalingsKenmerk , o.betaalMethode , o.tijdstipBezorging , o.datum"
                    + ", o.adres , o.huisnummer , o.postcode , o.woonplaats , o.landCode , o.extrainfo , o.opmerking"
                    + ", o.altEmail , o.voornaam , o.achternaam , o.bedrijfsnaam , o.telnummer , o.betaald , o.bezorgkosten"
                    + ", o.totaalExBzg , o.siteCode , o.opmerking"
                    + ", IF(o.transactieID = -1, 1,0) "
                    + "AS pickup, r.rest_id, TRIM(CONCAT(r.naam, ' ', r.filiaal)) AS restname"
                    + "FROM thuis.order o IGNORE INDEX(connectieid, doorberekenen)"
                    + "INNER JOIN connectie c IGNORE INDEX(methode)"
                    + "ON o.connectieId = c.id"
                    + "AND c.methode = 26 "
                    + "INNER JOIN restaurant r"
                    + "ON o.restaurantRest_id = r.rest_id"
                    + "WHERE o.datum >= TIMESTAMP(CURDATE())"
                    + "AND o.order_statusOrder_status_id = '1'"
                    + "AND o.order_statusOrder_device_id = ?"
                    + "AND o.doorberekenen = '1'"
                    + "AND ((o.bevestigingsId IS NULL OR o.bevestigingsId = 0) AND o.bevestigdDoor IS NULL)";

但是我收到错误:

[17-03-2015 10:20:57] [FATAL] [OrderCollector]
Error : com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'thuis.order o IGNORE INDEX(connectieid, doorberekenen)INNER JOIN connectie c IGN' at line 1

我已经在netbeans中的Sql管理器中尝试过对数据库进行这个查询，它工作得很好，但是当我尝试为java重新输入它时，它只是不断地给出上面的错误。

我找不到解决方案!

Answer 1

您缺少一个空格

改变

"FROM thuis.order o IGNORE INDEX(connectieid, doorberekenen)"

至

" FROM thuis.order o IGNORE INDEX(connectieid, doorberekenen)"

没有它，restnameFROM 就会变成一个单词，并且找不到 FROM 子句。

同样，您应该在大多数行的开头或结尾添加一个空格。

这应该有效:

String Retrieve 
                    = "SELECT o.order_id , o.betalingsKenmerk , o.betaalMethode , o.tijdstipBezorging , o.datum"
                    + ", o.adres , o.huisnummer , o.postcode , o.woonplaats , o.landCode , o.extrainfo , o.opmerking"
                    + ", o.altEmail , o.voornaam , o.achternaam , o.bedrijfsnaam , o.telnummer , o.betaald , o.bezorgkosten"
                    + ", o.totaalExBzg , o.siteCode , o.opmerking"
                    + ", IF(o.transactieID = -1, 1,0) "
                    + "AS pickup, r.rest_id, TRIM(CONCAT(r.naam, ' ', r.filiaal)) AS restname"
                    + " FROM thuis.order o IGNORE INDEX(connectieid, doorberekenen)"
                    + " INNER JOIN connectie c IGNORE INDEX(methode)"
                    + " ON o.connectieId = c.id"
                    + " AND c.methode = 26 "
                    + " INNER JOIN restaurant r"
                    + " ON o.restaurantRest_id = r.rest_id"
                    + " WHERE o.datum >= TIMESTAMP(CURDATE())"
                    + " AND o.order_statusOrder_status_id = '1'"
                    + " AND o.order_statusOrder_device_id = ?"
                    + " AND o.doorberekenen = '1'"
                    + " AND ((o.bevestigingsId IS NULL OR o.bevestigingsId = 0) AND o.bevestigdDoor IS NULL)";
