How do add NOLOCK with nHibernate?

Question

How do you add NOLOCK when using nhibernate? (criteria query)

Answer 1

I have taken @cbp answer and changed it a bit:

private static SqlString ApplyQueryHintNoLock(SqlString sql)
    {
        var sqlString = sql.ToString();

        if (_cache.Get(sqlString) is SqlString cachedSql)
        {
            //return cachedSql;
        }

        var regex1 = new Regex(@" FROM\s+[a-zA-Z1-9_.]*\s+([a-zA-Z1-9_.]*)", RegexOptions.IgnoreCase);
        var regex2 = new Regex(@"(?: INNER JOIN| LEFT OUTER JOIN)\s+[a-zA-Z1-9_.]*\s+([a-zA-Z1-9_.]*) ON", RegexOptions.IgnoreCase);

        var tableAliasMatches = regex1.Matches(sqlString);
        var joinsAliasMatches = regex2.Matches(sqlString);
        var combined = tableAliasMatches.OfType()
            .Concat(joinsAliasMatches.OfType())
            .Where(m => m.Success)
            .OrderBy(m=>m.Index);
        var noLockLength = " WITH (NOLOCK)".Length;
        var q = 0;

        foreach (Match aliasMatch in combined)
        {
            var alias = aliasMatch.Groups[1].Value;
            var aliasIndex = aliasMatch.Groups[1].Index + q + alias.Length;

            sql = sql.Insert(aliasIndex, " WITH (NOLOCK)");
            q += noLockLength;
        }

        _cache.Set(sqlString, sql, DateTimeOffset.Now.AddHours(3));

        return sql;
    }

    internal static string GetQueryHintNoLock()
    {
        return _queryHintNoLockCommentString;
    }

this way it will add no lock to all tables and inner joins in the query.

this is good for all of you using the unit of work pattern.
