    NAME

    DROP CAST - remove a cast
    

     

    SYNOPSIS

    DROP CAST (sourcetype AS targettype) [ CASCADE | RESTRICT ]
    
    
     

    DESCRIPTION

    DROP CAST removes a previously defined cast.

    To be able to drop a cast, you must own the source or the target data type. These are the same privileges that are required to create a cast.  

    PARAMETERS

    sourcetype
    The name of the source data type of the cast.
    targettype
    The name of the target data type of the cast.
    CASCADE
    RESTRICT
    These key words do not have any effect, since there are no dependencies on casts.
     

    EXAMPLES

    To drop the cast from type text to type int:

    DROP CAST (text AS int);
    
    
     

    COMPATIBILITY

    The DROP CAST command conforms to the SQL standard.
