C# sqlite选择行为

我使用sqlite.NETc 当我执行此语句时

"SELECT id, date, team1, team2, finalScore, winner FROM matches WHERE team1 = @team OR team2 = @team AND date BETWEEN @fromDate AND @toDate ORDER BY date DESC"

忽略team2=@team，仅当team1=@team时选择。 如果我删除或team2=@team，则返回查询将为空，而不应为空。 如果我将team1=@team或team2=@team放在括号中，则返回空查询

这是所有的代码

public System.Data.DataTable searchMatches(string team, string fromDate, string toDate)
{
    SQLiteCommand cm = new SQLiteCommand("SELECT id, date, team1, team2, finalScore, winner FROM matches WHERE team1 = @team OR team2 = @team AND date BETWEEN @fromDate AND @toDate ORDER BY date DESC", cnlite);
    cm.Parameters.AddWithValue("@team", team);
    cm.Parameters.AddWithValue("@fromDate", fromDate);
    cm.Parameters.AddWithValue("@toDate", toDate);
    SQLiteDataAdapter sda = new SQLiteDataAdapter(cm);

    System.Data.DataTable table = new System.Data.DataTable();
    sda.Fill(table);
    return table;
}
DataTable matches = db.searchMatches(sheetDataXlsx.Rows[i]["Ομαδα 1"].ToString(), matchDate.ToString("yyyy/MM/dd"),
                                                    matchDate.AddDays(-90).ToString("yyyy/MM/dd"));

PS日期是字符串yyyy/MM/dd，如中所述，其优先级高于或。 因此，您的查询相当于：

选择其中team1=？或者团队2=？日期在。。。 您必须手动添加括号以强制执行正确的求值顺序
