Question

在coldfusion组件中，我有不同的功能，我在其中创建一个sql查询并执行i。代码如下：

<cffunction name="buildQuery" access="public" returntype="string">
  <cfargument name="json"               required="yes"          type="struct">
  <cfset blockStatements = "">
  <cfloop index="j" from="1" to="#ArrayLen(arguments.json.rows[arguments.json.columns[1]])#">   
    <cfscript>
        statement = "insert into " & arguments.json.tableName &" ("&ArrayToList(arguments.json.columns)&") values (";
        for (i=1;i LTE ArrayLen(arguments.json.columns);i=i+1) {
          value = transformValue(arguments.json.rows[arguments.json.columns[i]][j],arguments.json.tableInfo[arguments.json.columns[i]]); 
          <!--- transformValue just return my value formated, if requires '' o numeric without them--->
          if(Find('identity',arguments.json.tableInfo[arguments.json.columns[i]],0)){
            statement = Replace(statement, ","&arguments.json.columns[i], "" , "all");
          }
            <!--- here I remove all primary keys from the exported data--->
            statement = statement & value & ",";
          }
        }
        statement = statement & ");";
        statement = Replace(statement, ",);", ");" , "all");
        blockStatements = blockStatements & statement;
      </cfscript>
    </cfif>
  </cfloop>
  <cfif blockStatements neq "">
    <cfscript> executeQuery(blockStatements);<cfscript>
  </cfif>
</cffunction>

<cffunction name="executeQuery" access="public" returntype="string">
  <cfargument name="query"  required="yes"      type="string">
  <cfdump var="#query#">
  <cfquery name="q_query" datasource="myDB">
    #Replace(query, "''", "'" , "all")#
  </cfquery>
</cffunction>

在line 4中，在致电executeQuery之前，queryString有一些特殊字符（á，é，í，ó，ú）。我已直接在我的query上测试了SQL DB，并按指定的方式工作，允许我在varchar列中包含这些特殊字符。

调用executeQuery函数后，在line 10上，所有这些特殊字符都被替换为'í' -> 'Ã-'。然后，该函数在DB中执行此“新”查询和insert。

调用函数时，如何在查询中保留这些特殊字符？应该有一种方法可以正确地进行，而不是从另一方replace。

我为上传表单添加了一个snipplet：

function validate(form) {
  console.log(window.b = form);
}

<form action="Importar_form.cfm" onsubmit="return validate(this);" method="post" enctype="multipart/form-data">
  <cfoutput>Escoja un archivo: </cfoutput><br/> 
  <input type="file" name="fileToUpload" id="fileToUpload" accept="text/plain, .txt"required>
  <br/><br/> 
  <input type="submit" value="Upload" name="submit">
</form>
<cfif isdefined('form.FILETOUPLOAD')>
  <cftry>
    <cfscript>
      myfile = FileRead("#form.FILETOUPLOAD#"); 
      record=deserializeJSON(myfile);
    </cfscript>
  <cfcatch>
    <cfthrow message = "Archivo da&ntilde;ado, no se puede cargar.">
  </cfcatch>
  </cftry>
  <cfset componentPath = "myproject.Componentes.ImportData">
  <cfset componentOBJ = createObject("component","#componentPath#")>
  <cfset result = componentOBJ.buildQuery(
        json = "#record#"
      , method = "#form.method#"
  )>
  <script>
    alert("Se ha importado con &eeacute;xito");
  </script>
  </cfif>

要上传的file.txt的内容：

{"tableName":"CRCParametros","tableInfo":{"Pcategoria":"varchar","Usucrea":"numeric","updatedat":"datetime","Pcodigo":"varchar","Pvalor":"varchar","TipoDato":"varchar","Mcodigo":"varchar","Pdescripcion":"varchar","createdat":"datetime","deletedat":"datetime","id":"intidentity","TipoParametro":"varchar","Parametros":"varchar","Usumodif":"numeric"},"keyColumnName":"Pcodigo","rows":{"Pcategoria":["Categoría"],"Usucrea":[24],"updatedat":[""],"Pcodigo":[30000601],"Pvalor":[10],"TipoDato":["E"],"Mcodigo":["CREDADM"],"Pdescripcion":["DiadeCorteQuincena1"],"createdat":["November,14201700:00:00"],"deletedat":[""],"id":[1],"TipoParametro":["R"],"Parametros":["1-15"],"Usumodif":[""]},"columns":["Pcategoria","Usucrea","updatedat","Pcodigo","Pvalor","TipoDato","Mcodigo","Pdescripcion","createdat","deletedat","id","TipoParametro","Parametros","Usumodif"]}

字面上ctrl + c，ctrl + v到内容。如您所见，json中的单词“Categoría”将作为“CategorÃ-a”在查询中保存在数据库中。但是DB支持角色“í”。

任何解释都会很乐意欣赏！
