Where I can see which default columns SQLite table will have after creating? I need a column with datetime which has default value of time when data added to the table.\
Now I'm trying:
ALTER TABLE recipes ADD COLUMN timestamp DATE DEFAULT (datetime('now','localtime'));
And I'm obtaining the following message:
SQLiteManager: Likely SQL syntax error: ALTER TABLE recipes ADD COLUMN timestamp DATE DEFAULT (datetime('now','localtime')); [ Cannot add a column with non-constant default ]
Exception Name: NS_ERROR_FAILURE
Exception Message: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [mozIStorageConnection.createStatement]
ADD DateOfBirth date; Notice that the new column, "DateOfBirth", is of type date and is going to hold a date. The data type specifies what type of data the column can hold. For a complete reference of all the data types available in MS Access, MySQL, and SQL Server, go to our complete Data Types reference.
On the Insert tab, in the Text group, click Date & Time. In the Date and time dialog box, select the format you want. Select the Update automatically check box. The date is inserted as a field and will update automatically.
Use the create table instead of altering the table. If there are values inside you'll have this kind of a problem. See
