Question

我有以下查询，我只想加载last_update_date大于值之一的数据，我以正确的方式欺骗该值，并在SQL Server数据源中正常工作，但是当我使用Oracle时日期源不起作用。我也尝试用：VARIABLENAME更改引号，这给了我这个错误：并非所有变量都受约束

无法从SQL命令中提取参数。提供程序可能不帮助从命令中解析参数信息。在这种情况下，请使用“来自变量的SQL命令”访问模式，在该模式下，整个SQL命令都存储在变量中。 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，然后在OLE DB源中使用“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，确保传递给Oracle数据源的日期格式是预期的日期格式。要在存储SQL的字符串变量中串联date参数，必须将其设置为强制转换为字符串，格式仍将保留，但这不能保证它将作为日期数据类型传递，并且可能需要强制转换。另外，请注意，如果转换后的字符串的长度大于指定的长度，并且随后将其截断，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。
