Visual Studio 2019 中的 SQL 查询生成器不读取 PL/SQL

Question

我尝试在 Visual Studio 2019 的 SQL Query Builder 中运行 PL/SQL 查询，不幸的是，Visual Studio 2019 中的 SQL Query Builder 似乎只能从 Microsoft SQL Server 读取 T-SQL。

这是我来自 Oracle 的 PL/SQL 查询：

我需要运行这个 PL/SQL 查询，以便我可以获取我的数据集的表和列。这是我的数据集：

Answer 1

经过2天的寻找解决方案我已经解决了我的问题，众所周知，Visual Studio 2019的DataSet Designer中的DataTable在结果被拖到类后具有强类型。所以我所做的是在类型转换发生之前，我已经将表中的 Column 转换为特定的数据类型，例如 Varchar2。这是解决我的问题的方法：

    SELECT
       CAST(rct.trx_number AS VARCHAR(20)) INVOICE_NUMBER,
       CAST(rct.trx_date AS VARCHAR(20)) SOLD_DATE,
       CAST(NULL AS CHAR) REPORTING_PARTNER_BRANCH_ID,
