Where clause on json data in Sql Server 2016


I have a nvarchar(1000) field in my table and I am storing JSON data in that column.

eg :

 CONTENT_RULE_ID    CONTENT_RULE
 1                  {"EntityType":"Inquiry", "Values":[1,2]}
 2                  {"EntityType":"Inquiry", "Values":[1,3]}
 3                  {"EntityType":"Inquiry", "Values":[2,4]}
 4                  {"EntityType":"Inquiry", "Values":[5,6,1]}
 6                  {"EntityType":"Inquiry", "Values":[8,1]}
 8                  {"EntityType":"Inquiry", "Values":[10,12,11]}

from this how can I get all the CONTENT_RULE_ID which is having inquiry id 1 using JSON_QUERY in sql server


Solution

  • @Harisyam, could you please try following query

    declare @val int = 1
    
    ;with cte as (
        select *
        from CONTENT_RULES
        cross apply openjson (CONTENT_RULE, '$')
    ), list as (
        select 
        CONTENT_RULE_ID, replace(replace([value],'[',''),']','') as [value]
        from cte 
        where CONTENT_RULE_ID in (
        select CONTENT_RULE_ID
        from cte 
        where [key] = 'EntityType' and [value] = 'Inquiry'
        ) 
        and [key] = 'Values'
    )
    select 
    CONTENT_RULE_ID, s.value
    from list
    cross apply string_split([value],',') s
    where s.value = @val
    

    I used SQL string_split function to get inquiry values one by one

    output is

    enter image description here

    A second query can be following one

    select
        CONTENT_RULE_ID
    from CONTENT_RULES
    cross apply openjson (CONTENT_RULE, '$')
    where replace(replace(value,'[',','),']',',') like '%,1,%'
    

    And maybe the most complete SQL query which requires OpenJSON support is as follows

    select
        content_rule_id,
        [value]
    from Content as c
    cross apply openjson(c.CONTENT_RULE, '$') with (
        EntityType nvarchar(100),
        [Values] nvarchar(max) as json
    ) as e
    cross apply openjson([Values], '$') as v
