sql - Impala Query: Find value in pipe-separated list -


i have column containing rows of pipe separated string values: 

|   cola    |  ___________ | 5|4|2|255 | | 5|4|4|0   | | 5|4|4|3   | | 5|4|4|4   |

i need create query select rows contain 4 or 5, never 2 or 3. along lines of: 

select t.cola my_table t (t in ("4", "5") , t not in ("2","3")

resulting in: 

|   cola    |  ___________ | 5|4|4|0   | | 5|4|4|4   |

i ended using combination of 2 answers below, using either method alone still left me rows containing "255". here's final query: 

select t.cola my_table t (t.cola in ('4', '5') or t.cola "%|5|%"         or t.cola "%|5" or t.cola "5|%") , t.cola not "%3%"     , t.cola not "%|2|%"  , t.cola not regexp "^2|%"  , t.cola not regexp "%|2$"

there more elegant way this, trick.

what using like function ?

where (t  '%4%' or t  '%5%') , (t not  '%2%' , t not  '%3%')

that should job.
