SQL query for values that are both available and null


Recommended Posts

I have a table (Table1) where one of the columns is the ID (Table2ID) for a second table (Table2).

I know how to query Table1 and get all of the values, my issue is to be able to return the corresponding Name from table 2. I'm stumbling over NULL and available ID.

Any assistance would be appreciated.

Thanks!

If you want to show null value then you have to try this query :

select  t1.table1id,  t1.table2id,  t2.table2name  from  table1 t1  left join  table2 t2  on  t1.table2id  =  t2.table2id ;

 

If you do not want to show that null values then use this query :

select  t1.table1id,  t1.table2id,  t2.table2name  from  table1 t1  inner join  table2 t2  on  t1.table2id  =  t2.table2id ;

 

I hope this will show you your desired answer. let me know if you do this.
