问题描述：
前端向后台传送sql语句，如果是单句比如“ oid>'1' ”，后台能够进入函数正常执行，如果是复杂语句比如oid>'1' or dlts>'0'，后台就不能进入函数执行。nutz2.0的时候没有问题。请问该如何解决

前端代码：
SQL=oid>'1' or dlts>'0'
$("#div_zhTable").datagrid({
border: true,
url:base+"/complexQuery",
queryParams:{"connStr":connJson,"tableName":tcname,"SQLStr":SQL,"geoStr":geostr,"pipeType":pipeType},
singleSelect:true,//是否单选
pagination:true,//分页控件
loadMsg:"数据读取中。。。",
pageSize: 5,
pageNumber:1,
pageList:[5,10,15],
columns:zhSearchhelp.columnjson,
// onDblClickRow: fly2Line,
loadFilter: function(data){……
}
后台代码：
@At
@AdaptBy(type = JsonAdaptor.class)
@Ok("raw")
public String complexQuery(@Param("connStr") String connStr, @Param("pipeType") String pipeType, @Param("tableName") String tableName, @Param("SQLStr") String SQLStr,@Param("geoStr") String geoStr,@Param("page") int curPage, @Param("rows") int pageSize)
