SSIS 条件拆分错误 - 表达式评估为 NULL，但“条件拆分”需要 Boolean 结果

Question

It is my first time using this software. I am trying to split the value but it is showing this and I do not have any null have when I see my source but when I preview it, it shows null value in the first 200 columns but I have only 15 columns.

Error: 0xC020902B at Data Flow Task, Conditional Split [2]: The expression "[Copy of RATE_INR] > 1000" on "Conditional Split.Outputs[Case 1]" evaluated to NULL, but the "Conditional Split" requires a Boolean results. Modify the error row disposition on the output to treat this result as False (Ignore Failure) or to redirect this row to the error output (Redirect Row). The expression results must be Boolean for a Conditional Split. A NULL expression result is an error.

Answer 1

You are using the following expression in your conditional split component:

[Copy of RATE_INR] > 1000

As mentioned in the error message, this expression is evaluated as NULL which throws an exception since the conditional split component requires a boolean result (True/False).

You can solve this problem by using the REPLACENULL function:

REPLACENULL([Copy of RATE_INR],0) > 1000

Or

REPLACENULL([Copy of RATE_INR] > 1000, False)
