需要帮助将此外部应用转换为左连接

Question

过去几天我一直在为此苦苦挣扎。我正在尝试将在 SQL Server 2008 上使用的以下 SQL 查询用于 SQL Server 2000。

出现问题是因为SQL Server 2000 不支持outer apply 命令。是否可以转换我的查询，使其适用于 SQL Server 2000？

           ELSE kondisisebelumta2018

您可以将外部应用移动到相关的子查询。

 SELECT [ta_kib_b].*,
       ( CASE
           WHEN newkondisi IS NULL THEN kondisi
           ELSE newkondisi

FROM   (SELECT [ta_kib_b].*,
               (SELECT TOP 1 [ta_kibbr].kondisi AS NEWKONDISI
                FROM   [ta_kibbr]
                WHERE  [ta_kib_b].kd_bidang = [ta_kibbr].kd_bidang
