To add a new table column, you should either:
Specify the Field Name and specify the Field Data Type by selecting it from the drop-down list.
Note: the name of the object must be unique among all the object names in the table. You can use any identifier that is allowed by Firebird server.
Specify subtype for BLOB. The subtypes are used to categorize the data type when defining BLOBs. A subtype is a positive or negative numerical value, which indicates the type of BLOB data. The following subtypes are predefined in InterBase/Firebird:
0: Standard blob, non-specified binary data;
1: Text blob, e.g. memo fields;
Text: Alternative for defining subtype 1;
Positive value: Reserved for InterBase;
Negative value: User-defined blob subtypes.
