Kindly ensure, the other columns are not constrained to accept Not null
values, hence while creating columns in table just ignore "Not Null" syntax. eg
Create Table Table_Name(
col1 DataType,
col2 DataType);
You can then insert multiple row values in any of the columns you want to. For instance:
Insert Into TableName(columnname)
values
(x),
(y),
(z);
and so on…
Hope this helps.
