参数化有一个优势是天生可防御sql注入。这个问题可能需要一起考虑。

SmartSql/src/SmartSql/Configuration/Tags/SqlText.cs

Lines 44 to 50 in 5620943

foreach (var itemVal in enumParams)
{
string itemParamName = $"{paramName}_{itemIndex}";
inParamSql.AppendFormat("{0}{1},", _dbPrefix, itemParamName);
context.Parameters.TryAdd(itemParamName, itemVal);
itemIndex++;
}

通过集合的第一个元素判断集合元素类型，如果是int,long等数字类型就直接拼接，bool类型转换成0/1再拼接，字符串用'包围，日期转换成字符串再用'包含后拼接，应该不会有注入问题

efcore是判断你是常量还是变量如果是变量那么就是参数化如果是常量才是直接在sql中

我这项目里有很多查询都依赖于用户当前有权限的组织，所以组织每次都是通过调接口获取的。然后生成的查询里，组织Id都是直接在SQL里，并没有参数化。
