Problem IC69718
|
Status: Closed |
INCORRECT ROWCOUNT IN SQLERRD[2] (OR FROM GET DIAGNOSTICS) WHEN A GLOBAL VARIABLE IS INSTANTIATED |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
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. |

* PROBLEM DESCRIPTION: *
* incorrect rowcount from sqlca, GET DIAGNOSTIC *

* RECOMMENDATION: *
* Move to DB2 for LUW version 9.7, fixpack 3 *

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