DB2 FOR LUW / DB2FORLUW / 970 - DB2

If an insert, update or delete statement refers to global 
variable and the reference is the first time the global variable 
is referenced in the connection, then sqlerrd[2] value in the 
SQLCA for this statement will be incorrectly incremented by 1 
giving an inflated row count.   Similarly if the statement is in 
an SQL procedure, GET DIAGNOSTICS will return an inflated 
rowcount. 
 
So, for example: 
 
CREATE TABLE T1 (i int) 
insert into T1 values 1,2,3 
CREATE VARIABLE var1 INT default 0 
 
 
In a new connection: 
 
update t1 set i=i+1 where i > var1 
 
The sqlerrd[2] value from the sqlca from this operation will 
show a value of 4 instead of 3 
 
If the statement is referenced again, then the count will be 
correct.

If the row count value is relevant, reference global variable in 
a separate statement before referencing it in an 
update/delete/insert statement.
