I have a sql table with sql_varient column. I want to query the table to get the records which has value. I used following query
SELECT *
from Table
WHERE sql_varient_column IS NOT NULL
But its return the data which has no data also. How can I achieve this
To get the row for column sql_varient_column
is not null and not empty:
SELECT *
from Table
WHERE NULLIF(sql_varient_column, '') IS NOT NULL
试试这个:
SELECT * FROM Table Where sql_varient_column != ''
I think you want this.
you can try it
SELECT *
from Table
WHERE ISNULL(sql_varient_column,'') != ''
