We can configure these tools by following these steps: package net.petrikainulainen.todo; import

someone asked "how do I identify an atrans" i said -- you cannot. It would be like trying to pick the cloned sheep daisy out of a herd of sheep. Hi Tom, With all the respect to you, don't get me wrong I only want to know if autonomous transaction opens another session or uses the same session.
Unless you yourself placed daisy in the herd, you would have no clue which one was she. I feel it uses same session still we have people with different opinions just wanted to know the right thing. August 25, 2003 - am UTC uses the same session -- it is just an independent sub transaction.
My question is, is there any relation between the usage of SELECT FOR UPDATE clause and the primary key of a table? In any case, I cannot reproduce - you'll have to show us how to step by step by step: [email protected] For example, it is possible that the rows in SO_LINE_DETAILS can be locked before the rows in SO_PICKING_LINE_DETAILS. If one user ran this query under the RBO, and another user ran this query under the CBO, locking order issues could arise due to the likelihood of a plan difference.
The previous part of this tutorial described how we can create database queries with named queries. This tutorial has already taught us how we can create database queries by using the method names of our query methods, the annotation, and named queries.
This tutorial has already taught us how we can create static database queries with Spring Data JPA. Optional; interface Todo Repository extends Repository import org.springframework.beans.factory.annotation. Specification; import org.springframework.stereotype. Service; import org.springframework.transaction.annotation. The problem of these query generation methods is that we cannot use them if we have to create dynamic queries (i.e queries that don’t have a constant number of conditions).
I modified my WHERE clause to include all the columns of my primary key in the table (PRS_BSNS_SGMNT, PRS_BSNS_SUB_SGMNT, PRS_DATE, PRS_WOO_PRCS_ID). declare cursor c1 is select PRS_BSNS_SGMNT, PRS_BSNS_SUB_SGMNT, PRS_DATE, PRS_WOO_PRCS_ID,prs_sts from prcs_sts where PRS_BSNS_SGMNT = 'FRX' AND PRS_BSNS_SUB_SGMNT = 'USDINR' AND PRS_DATE = '28-MAR-02' AND PRS_WOO_PRCS_ID = 'PF31' for update of prs_sts; begin for c1_rec in c1 loop update prcs_sts set prs_sts = 'Y' where current of c1; end loop; end; / PL/SQL procedure successfully completed.
declare PRAGMA AUTONOMOUS_TRANSACTION; cursor c1 is select PRS_BSNS_SGMNT, PRS_BSNS_SUB_SGMNT, PRS_DATE, PRS_WOO_PRCS_ID,prs_sts from prcs_sts where PRS_BSNS_SGMNT = 'FRX' AND PRS_BSNS_SUB_SGMNT = 'USDINR' AND PRS_DATE = '28-MAR-02' AND PRS_WOO_PRCS_ID = 'PF32' for update of prs_sts; begin for c1_rec in c1 loop update prcs_sts set prs_sts = 'Y' where current of c1; end loop; COMMIT; end; / PL/SQL procedure successfully completed.
