The Column Properties Window allows you to modify all column properties.
It consists of two tabs: General and Data Type.
The General tab contains column name, primary key, and NULL constraints flags,
and DEFAULT value field.
The Data Type tab allows you to define all data type related information,
including data type name and data type specific properties, such as LENGTH
for CHAR data types or FROM-TO modifiers for DATETIME data types. The
Collection button is displayed for Informiz Dynamic Server, Version
9.x, to allow defining collection data types, such as LIST, SET, and MULTISET.
To open the Column Properties Window, double-click a column in the Table
Editor grid or choose a column in the grid and select Properties from the
popup menu.
Press OK to apply the changes to the Table Editor.
