-25323: Error in command; the data type of the constant in the column’s NULL condition is not compatible with the external column data type 

Explanation:

Error when unloading data using the DATAEXTRACT command.

You can specify a NULL value for individual columns in the command. This means that if a NULL value is extracted, the constant value you entered in the command is written in the data stream.

The data type of the constant value you specified and the external data type of the column to be extracted must be compatible. If you do not specify a data type in the command, the default data type CHAR is used.

User Action:

Correct the statement and re-execute it.
