#Oracle apex sql query transformation rule update
A row sequence can be useful to simplify lost update detection. You can add a row sequence column that automatically increments by one on each row update. You can automatically add Who Columns, for example, who created or last updated a given row and when. Object names are automatically formatted, replacing spaces with underscores, so you can use spaces in column and table names.Ĭlick the Settings button to view many generation options. Click Help and then Data Types to view the available syntax. If you want to specify a specific VARCHAR2 length, enter VCn where n is the length of the VARCHAR2. Based on the English text contained in the column name, and in the absence of any data Type specified, the system makes educated deductions for some column names.įor example, if the column name contains the word DATE then it will be a date data type, or if the column name contains the word NUMBER or NUM then it will be a number data type. If you want a column of a different data Type, add a space NUM, INT, DATE to the end of a column name. As a best practice, do not specify primary keys, the system will generate them for you.
