使用临时 table 的左连接不起作用

Question

我正在尝试在 table "x" 上执行 "left join" 但我需要 "row_number"，所以我正在使用临时 table "with" 命令，但查询不起作用，我收到以下错误：

SQL Error [156] [S1000]: Incorrect syntax near the keyword 'WITH'. Incorrect syntax near the keyword 'WITH'. Incorrect syntax near the keyword 'WITH'. Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon. Incorrect syntax near ')'.`

有人知道如何解决这个问题

SELECT telefoneEnriquecido1. FROM VPOTPRP P
    LEFT JOIN (
        WITH tel AS (
            SELECT
                ID_PROSP,
                DT_INC,
                ID_NUM_TEL AS novoTelefone,
                DT_ATC AS dataAtualizacao,
                ROW_NUMBER() OVER (PARTITION BY ID_PROSP ORDER BY DT_ATC DESC) AS rowNumber
            FROM
            VPOTTEL
        )
        SELECT
        FROM tel
        WHERE
        rowNumber = 1
    ) telefoneEnriquecido1 on p.ID_PROSP = telefoneEnriquecido1.ID_PROSP

奇怪的语法。我总是发现嵌入在查询中的 CTE 令人困惑，尽管有些数据库支持它们。我没有发现 CTE 向查询添加任何内容；只需使用子查询：

SELECT . . .   -- whatever columns you want
FROM VPOTPRP P LEFT JOIN (
     (SELECT ID_PROSP, DT_INC, ID_NUM_TEL AS novoTelefone,
             DT_ATC AS dataAtualizacao,
             ROW_NUMBER() OVER (PARTITION BY ID_PROSP ORDER BY DT_ATC DESC) AS rowNumber
      FROM VPOTTEL
     ) PL
     ON P.ID_PROSP = PL.ID_PROSP AND rowNumber = 1

使用临时 table 的左连接不起作用

Left join using temporary table is not working

sql

sql-server

row-number

left-join
