如何创建临时主键Azure TSQL服务器

我需要检查名为User的表中可能存在的重复地址。为此，我使用连接，然后比较地址字符串中第一组街道编号的表。例如，“123 First Street”和“123 First St.”需要标识为可能的匹配/重复项

但是，我还需要显示记录的Telerik RadGrid具有唯一的DataKeyName来标识行，以便双击javascript函数工作

由于连接，我的普通主键在“两个”表a和b中都是重复的。如何使用SQL创建临时psuedo主键，以便datagrid能够识别双击的行

    try
    {
        //Select Query to populate the RadGrid.   
        string selectQuery =

            "SELECT " +
            //We rename the dbo.User table as "a" then rename it again as "b" so we can look for duplicate Street Address numbers
            "a.Id AS LeftID,a.DateSubmitted AS LeftDateSubmitted,a.Updated AS LeftUpdated," +
            "a.Status AS LeftStatus,a.StreetAddress AS LeftStreetAddress," +

            "b.Id AS RightID,b.DateSubmitted AS RightDateSubmitted,b.Updated AS RightUpdated," +
            "b.Status AS RightStatus,b.StreetAddress AS RightStreetAddress " +

            //We join the 2 virtual dbo.User tables where table b Id's are greater than table a meaning b records are newer
            "FROM [User] a JOIN [User] b ON b.Id > a.Id AND " +

            //LEFT selects the left most characters (usually numbers) in the StreetAddress field string before the space ' '
            //and eliminates the rest of the address isolating just the street address numbers for matching
            "LEFT(a.StreetAddress,CHARINDEX(' ',a.StreetAddress)) = LEFT(b.StreetAddress,CHARINDEX(' ',b.StreetAddress)) " +

            //Don't show orange or blue status records
            "AND b.Status != 'Orange' AND a.Status != 'Orange' AND a.Status != 'Blue' AND b.Status != 'Blue' " +

            //If a b record (newer) is red then ignore because it is completed and ignore a records (oldest) older than 90 days
            "WHERE a.DateSubmitted >= (GetDate() - 90) AND b.Status != 'Red' " +

            //Show newest records first
            "ORDER BY b.DateSubmitted DESC"
            ;

        SqlDataAdapter.SelectCommand = new SqlCommand(selectQuery, SqlConnection);
        SqlDataAdapter.Fill(dtTable);
        RadGrid1.DataSource = dtTable;

如果只想为每行生成一个随机ID，请将NEWID（）函数添加到列列表中
