General Column Properties


The General tab of the column edit panel is used to edit the basic properties of a column.


Column Panel's General Tab

Disabled Items - Some input items, such as length and scale are disabled if the selected data type does not require them.

Unsigned - This checkbox is used to specify unsigned (positive only) numbers.

Column Defaults - Default values should not be enclosed in quotes. DbWrench forward engineering will enclose string values in quotes automatically.
To prevent function default strings from being automatically enclosed in quotes, the function string should be preceeded with a backtick (`). Default strings containing '()' will be recognized as functions and do not need to be escaped with a backtick. Exceptions are made for MySQL versions prior to 5.0, which require quotes for function default values. For more information see: Forward Engineering
