我需要执行LIKE查询。我创建如下:

AData ad : ao.find(AData.class, Query.select().where("user=? AND ISSUES LIKE %?%",user,issueId)))      //issues field contain values as //"FIN-1,FIN-2,FIN7". issueId parameter has value as FIN-7

它给我以下错误:

java.sql.SQLException: Unexpected token: % in statement [SELECT * FROM PUBLIC.AO_0371A8_ADATA WHERE    user=? AND ISSUES LIKE %?%]

将以下查询更新为:

AData ad : ao.find(AData.class, Query.select().where("user=? AND ISSUES LIKE '%? %'",user,issueId)))  //issues field contain values as //"FIN-1,FIN-2,FIN7". issueId parameter has 

值为FIN-7

它给了我以下错误:(参数索引超出范围:2)(也尝试为“....... LIKE \'%?%\'”...但是给我同样的错误如下:

com.atlassian.activeobjects.internal.ActiveObjectsSqlException: There was a SQL exception thrown  by the Active Objects library:

  ..
   .

尝试以下查询时:

AData ad : ao.find(AData.class, Query.select().where("user=? AND ISSUES LIKE '%?%'  ",user,issueId)))      

以及其他方式,

     AData ad : ao.find(AData.class, Query.select().where("user=? AND ISSUES LIKE ? ",user, "%" +   
issueId + "%")))      

在上述两种情况下,得到以下错误:(主要是错误说,“java.sql.SQLException:JDBC调用中的参数无效:参数索引超出范围:2”)。

它是如何工作的..这个LIKE查询有什么问题?

谢谢

2 个答案:

答案 0 :(得分:1)

更新:LIKE的参数是一个SQL字符串。您在SQL中使用单引号作为字符串。

您可以使用参数标记替换整个参数。

然后为两个参数提供值。第二个参数的值应该是一个字符串,其中可以包含通配符元素。这个例子看起来是正确的。

AData ad : ao.find(AData.class, Query.select().where("user=? AND ISSUES LIKE ?",user, "%" + issueId + "%")))   

答案 1 :(得分:0)

这是您在上面的代码中使用的类似SQL的语法:

where("user=? AND ISSUES LIKE %?%",user,issueId)

'%'通配符仅在引用的文字或提供的参数字符串中使用时有效。用法“LIKE%?%”无效。替换为:

ISSUES LIKE ?

如果此语句的参数为'THO',则需要将其修改为'%THO%'才能获得我认为您想要的通配符函数(例如,LIKE?with the parameter set '%THO%'会匹配,尽管,但仍然和FATHOM相同。
