在oracle数据源SSIS中将变量传递给OLE DB源

Question

我有以下查询，我只想加载 last_update_date 大于其中一个值的数据，我以正确的方式迷惑该值及其在 SQL Server 数据源中的工作，但是当我使用 Oracle 日期源时它不工作。我也尝试用 :VARIABLENAME 更改引号它给了我这个错误： 并非所有变量都绑定

无法从 SQL 命令中提取参数。提供程序可能无法帮助解析命令中的参数信息。在这种情况下，请使用“来自变量的 SQL 命令”访问模式，其中整个 SQL 命令都存储在一个变量中。 ORA-00920: 无效的关系运算符 (OraOLEDB)

Answer 1

您可以在字符串变量中构建查询，然后使用 OLE DB 源中的“来自变量的 SQL 命令”选项并在查询中添加参数。但是，在执行此操作时，确保传递到 Oracle 数据源的日期格式是预期的日期格式。要在保存 SQL 的字符串变量中连接日期参数，它需要是转换为字符串，格式仍将保留，但这并不能保证它将作为日期数据类型传递，并且可能需要进行转换。另请注意，如果转换的字符串长度超过指定长度并且随后被截断，则字符串转换函数(DT_STR, number of characters, code page) 将返回错误。下面是字符串变量中 SQL 的示例表达式。
