== Why is this an issue?
|
|
|
|
Any insert which omits a value for a `NOT NULL` column in a database table will be automatically rejected by the database unless a default value has been specified for the column.
|
|
|
|
include::../../../shared_content/plsql/data_dictionary.adoc[]
|
|
|
|
== How to fix it
|
|
|
|
Ensure that all `NOT NULL` columns have a value specified in the `INSERT` statement.
|
|
|
|
=== Code examples
|
|
|
|
Given the following table:
|
|
|
|
[source,sql]
|
|
----
|
|
CREATE TABLE MY_TABLE (
|
|
N1 NUMBER NOT NULL,
|
|
N2 VARCHAR2(50) NOT NULL,
|
|
N3 VARCHAR2(50) DEFAULT 'Default Value'
|
|
);
|
|
----
|
|
|
|
==== Noncompliant code example
|
|
|
|
[source,sql,diff-id=1,diff-type=noncompliant]
|
|
----
|
|
INSERT INTO MY_TABLE -- Noncompliant; N2 value omitted
|
|
(
|
|
N1
|
|
)
|
|
VALUES
|
|
(
|
|
1
|
|
)
|
|
----
|
|
|
|
=== Compliant solution
|
|
|
|
[source,sql,diff-id=1,diff-type=compliant]
|
|
----
|
|
INSERT INTO MY_TABLE -- Compliant; N3 has a default value
|
|
(
|
|
N1,
|
|
N2
|
|
)
|
|
VALUES
|
|
(
|
|
1,
|
|
'Paul'
|
|
)
