在下面的代码中，我想添加“IN”+Village+。在代码中的何处添加此条件。变量村从下拉列表中获取值，基于该过滤器应该发生。请帮助我。村名是我的融合表中的一列。
即从 querypass > textvalue IN villagename='madurai' 的表中选择'geometry',villageName

function querymape()
        {
        /*variable holds the value*/ 
        var village =document.getElementById('village').value.replace(/'/g, "\\'");
        var operatore=document.getElementById('operatorstringe').value.replace(/'/g, "\\'");
        var textvaluee=document.getElementById("text-valuee").value.replace(/'/g, "\\'");
        var querypasse=document.getElementById('query-passe').value.replace(/'/g, "\\'");

            {
             layer.setQuery("SELECT 'geometry'," + querypasse + " FROM " + tableid + " WHERE " + querypasse + " " + operatore + " '" + textvaluee + "'"+"AND 'VillageName=+village+'");
            }


    }

/*This is my new code.But its not working.Please help me*/
function querymap()
{
//var villagename='';
var operator=document.getElementById('operatorstring').value.replace(/'/g, "\\'");
var textvalue=document.getElementById("text-value").value.replace(/'/g, "\\'");
var querypass=document.getElementById('query-pass').value.replace(/'/g, "\\'");
var searchStringe = document.getElementById('Search-stringe').value.replace(/'/g, "\\'");
    {
     layer.setQuery("SELECT 'geometry'," + querypass + " FROM " + tableid + " WHERE " + querypass + " " + operator + " '" + textvalue + "'"+"AND 'VillageName'="+ searchStringe+"");
    }

}

  1. 可以使用关键字“和”组合多个条件？
  2. 您扭曲了 IN 语法，当您想要匹配多个值时使用它，如果您只想与单个值进行比较，请使用“ = ”代替

应用于您的查询（使用 IN 语法）：

     select 'geometry',villageName from table where querypass > textvalue and villagename IN ('madurai','another village')

使用 = 语法：

     select 'geometry',villageName from table where querypass > textvalue and villagename = 'madurai'
