How to get specified data from the table column using where clause

Question

I've a table having the columns like

         Prefix                     CModel

          g                     ;#WR_1;#WR_2;#WR_3;#WR_4;# 

          v                  ;#WR_3;#WR_4;#

         j                     WR_2

         m                     WR_1

         d              ;#WR_3;#WR_4;#   

          f9                      WR_3

I want to retrieve data from all columns WHERE CModel=WR_3 from CModel.

SELECT Prefix,CModel From table1 WHERE CModel = WR_3;

It returns only one row.

                Prefix      CMODEL

                f9        WR_3

i want it to be return 4 rows since WR_3 exists in 4 rows(contains colon delimted like ;#WR_3;#WR_4;#).How to specify that in WHERE Condition?

Answer 1

Given your table structure, I would use something like this:

SELECT Prefix, CModel
FROM table1
WHERE
  [CModel] IS NOT NULL
  AND (";" & Replace([CModel], "#", "") & ";") Like "*;WR_3;*";

• Replace([CModel], "#", "") will remove all # characters from the model
• ";" & Replace(...) & ";" will add one ; at the beginning and one ; at the end of the string
• Like "*;WR_3;*" will match all strings that contain ;WR_3; so it will also match rows that contain just WR_3 but it won't match rows that contain WR_30
