在SQL中合并2个Not Like语句

Question

I have a formula where I have a column for region and a column for district (a region is made up of districts), in the formula i have some pieces of code to exclude certain regions as a whole. But some i need to only exclude a few districts from some regions but not all. The where portion of the code looks like this: In the code I want to exclude all of Region 100 and region 76, but for region 88 I only want to exclude District 04 but when i type the code like this it stil excludes all of 88. (There is no GROUP BY in this code)

SELECT ID, Date, Class, Location, Training Number
FROM Table 1 INNER JOIN Table 2 ON Training Number     
WHERE (Region NOT LIKE '100') AND 
      (Region NOT LIKE '76') AND 
      (Region NOT LIKE '88') AND 
      (District NOT LIKE '04')

Answer 1

I am not sure why you are using the LIKE operator, you should be able to use:

SELECT ID, Date, Class, Location, Training Number
FROM Table 1 
INNER JOIN Table 2 
  ON Training Number     
WHERE Region <> '100' 
  AND Region <> '76'
  AND 
  (
    Region <> '88' 
    OR District <> '04'
  );

Or you can use NOT IN :

SELECT ID, Date, Class, Location, Training Number
FROM Table 1 
INNER JOIN Table 2 
  ON Training Number     
WHERE 
(
  Region NOT IN ('100', '76')
)
AND 
(
  Region <> '88' 
  OR District <> '04'
)

Answer 2

How about something like:

SELECT ID, Date, Class, Location, Training Number
FROM Table 1 INNER JOIN Table 2 ON Training Number     
WHERE (Region <> '100') AND -- Region cannot be 100
      (Region <> '76') AND  -- Region cannot be 76
      (Region <> '88' OR District <> '04') -- Region cannot be 88 if District is 04

Answer 3

Just do this:

where Region not in ('100', '76', '88') and district <> '04'

You don't need to use like for this.
