不带硬编码列名的Nhibernate查询版本排序规则

因此，我有以下sql

从名称对照拉丁语1_GENERAL_CI_AI如“myText%”的表格中选择*

我想用QueryOver实现它

目前我有：

whereRestriction.Add(Expression.Sql("Name COLLATE LATIN1_GENERAL_CI_AI LIKE ?", String.Format("{0}%", subStringMatch), HibernateUtil.String));

这很好，但有两个问题。首先，它是特定于sqlserver的，其次，数据库列“Name”是硬编码的

---

有没有人有任何建议来解决这两个问题，或者至少是硬编码的db列名

我是这样实现的。不确定是否有更好的方法

I.like表达式，从现有like表达式中获益

public class LikeCollationExpression : LikeExpression
{
    const string CollationDefinition = " COLLATE {0} ";
    const string Latin_CI_AI = "LATIN1_GENERAL_CI_AI";

    // just a set of constructors
    public LikeCollationExpression(string propertyName, string value, char? escapeChar, bool ignoreCase) : base(propertyName, value, escapeChar, ignoreCase) { }
    public LikeCollationExpression(IProjection projection, string value, MatchMode matchMode) : base(projection, value, matchMode) { }
    public LikeCollationExpression(string propertyName, string value) : base(propertyName, value) { }
    public LikeCollationExpression(string propertyName, string value, MatchMode matchMode) : base(propertyName, value, matchMode) { }
    public LikeCollationExpression(string propertyName, string value, MatchMode matchMode, char? escapeChar, bool ignoreCase) : base(propertyName, value, matchMode, escapeChar, ignoreCase) { }

    // here we call the base and append the COLLATE
    public override SqlString ToSqlString(ICriteria criteria, ICriteriaQuery criteriaQuery, IDictionary<string, IFilter> enabledFilters)
    {
        // base LIKE
        var result = base.ToSqlString(criteria, criteriaQuery, enabledFilters);

        var sqlStringBuilder = new SqlStringBuilder(result);

        // extend it with collate
        sqlStringBuilder.Add(string.Format(CollationDefinition, Latin_CI_AI ));

        return sqlStringBuilder.ToSqlString();
    }
}
