    <p>I have an Oracle database, and a table with several not null columns, all with default values. </p> <p>I would like to use one insert statement for any data I want to insert, and don't bother to check if the values inserted are nulls or not. </p> <p>Is there any way to fall back to default column value when null is inserted?</p> <p>I have this code:</p> <pre><code>&lt;?php if (!empty($values['not_null_column_with_default_value'])) { $insert = " INSERT INTO schema.my_table ( pk_column, other_column, not_null_column_with_default_value) VALUES (:pk_column,:other_column,:not_null_column_with_default_value) "; } else { $insert = " INSERT INTO schema.my_table ( pk_column, other_column) VALUES (:pk_column,:other_column) "; } </code></pre> <p>So, I have to omit the column entirely, or I will have the error "trying insert null to not null column". Of course I have multiple nullable columns, so the code create insert statement is very unreadable, ugly, and I just don't like it that way.</p> <p>I would like to have one statement, something similar to:</p> <pre><code>INSERT INTO schema.my_table ( pk_column, other_column, not_null_column_with_default_value) VALUES (:pk_column,:other_column, NVL(:not_null_column_with_default_value, DEFAULT) ); </code></pre> <p>That of course is a hypothetical query. Do you know any way I would achieve that goal with Oracle DBMS?</p> <p><strong>EDIT</strong>:</p> <p>Thank you all for your answers. It seams that there is no "standard" way to achieve what I wanted to, so I accepted the IMO best answer: That I should stop being to smart and stick to just omitting the null values via automatically built statements.</p> <p>Not exactly what I would like to see, but no better choice. </p>

    1. COwhy don't you enter default value of the column "not_null_column_with_default_value" instead of the word "DEFAULT" inside the "hypothetical query"?

    2. COCause I do not know what is the default value at the moment of inserting. But as @Vincent Malgrat suggested I can fetch that form ALL_TAB_COLUMNS

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
