Answer 1

这个错误非常自我描述,你有一个未终止的引用.

您正在尝试运行SQL Server代码Oracle.这不行.

你不能仅仅通过复制就变成T-SQL了PL/SQL.

我纠正了语法,但很可能你需要更多的工作.

DECLARE
    colname NVARCHAR2(50);
    tname   NVARCHAR2(500);
    query   NVARCHAR2(500);
BEGIN
    SELECT  wk_units1
    INTO    colname
    FROM    cnt_sls_dm.fct_sales_summary;
    SELECT  tablename
    INTO    tname
    FROM    dmi_user.fct_sales_meta;
    query := 'SELECT ' || colname || ' FROM ' || tname;
END;
