2.17 References to host variables

For example, if :V1:V2 is used to specify an insert or update value, and if V2 is negative, the value specified is the null value. If V2 is not negative, the value specified is the value of V1.
Similarly, if :V1:V2 is specified in a FETCH or SELECT INTO statement, and if the value returned is null, V1 is not changed and V2 is set to -1 or -2. It is set to -1 if the value selected was actually null. It is set to -2 if the null value was returned because of numeric conversion errors or arithmetic expression errors in the SELECT list of an outer SELECT statement. It is also set to -2 as the result of a character conversion error. If the value returned is not null, that value is assigned to V1, and V2 is set to zero (unless the assignment to V1 requires string truncation, in which case V2 is set to the original length of the string). If an assignment requires truncation of the seconds part of a time, V2 is set to the number of seconds.
