在Access 2010中执行SQL子查询时，“条件表达式中的数据类型不匹配”

Question

Here is my simplified code (little more than some basic elements to cause the SQL not to execute):

select *
from (
    select replace(mytxtfield, "llama", "") as badones 
    from XYZ
)
where badones is not null;

The outer query runs fine when the WHERE cause is:

 badones like "ZZZ-[0-9][0-9][0-9]"

but it breaks when the WHERE cause includes more than one LIKE (of any digit matching pattern) such as:

badones like "ZZZ-[0-9][0-9]" OR 
badones like "ZZZ-[0-9][0-9][0-9]"

More info:

• mytxtfield is of type Text
• It doesn't matter if there is a WHERE cause in the inner query to check eliminate null / empty strings.

Answer 1

Since your sub-query returns the alias "badnews", you must use it in place of "badones" in your outer query. The following produces no errors:

SELECT *
FROM (select replace(mytxtfield, "llama", "") as badnews 
    from XYZ
)  
WHERE (((badnews) Like "ZZZ-[0-9][0-9]" Or (badnews) Like "ZZZ-[0-9][0-9][0-9]"));
