I insert a few records in the stored procedure sp1, and then call the stored procedure sp2
Then sp2 triggered is unusual, I stopped in the sp1 is unusual, call rollback after exit
Query data discovery, insert a few data in the sp1 didn't rollback success

 
Insert into t1 values (x, y, z); 
Insert into t2 values (x, y, z); 

The begin 
R:=0; 
Sp2 (p1, p2); 
R:=1; 
The exception 
The when others then null; 
-- tried to rollback here, there is no success 
end; 

If r!=1 then 
The rollback. -- not the rollback perform 
return; 
End the if;

In sp2 DDL statements, the error during execution of this statement

Look at the sp2 abnormal how to deal with it

see how sp2 exception handling

sp2 not handle directly out of the race

CodePudding user response:

Exit cannot directly on the outer catch exceptions, at the same time, the value of r 1

CodePudding user response:

Proposed to sp2 null or return to raise

My outer can capture the mistake, now the focus is not the mistake, but why don't the rollback work

You directly the debug

CodePudding user response:

Just try it

 

Insert into t1 values (x, y, z); 
Insert into t2 values (x, y, z); 

Sp2 (p1, p2, r); 

If r!=1 then 
The rollback. -- not the rollback perform 
return;

literally try

 

Insert into t1 values (x, y, z); 
Insert into t2 values (x, y, z); 

Sp2 (p1, p2, r); 

If r!=1 then 
The rollback. -- not the rollback perform 
return; 
End the if; 

Tried, but as long as the call after sp2, whatever where call rollback will not success
But if the rollback before calling sp2, can be successful

sure go into a branch of the rollback

words, according to the process, if the code did not enter the branch of the rollback, then represent no error occurs, the result is I can't find the rollback execute invalid
And I know the rollback execution is invalid, then certainly into the branches to the right...
