I have a requirement to update the custom fields - zzpdf and zzpdfdt of VBRK table. When executing program it should update zzpdf with X (Active) and zzpdfdt with the current date.
So is there any Function module I can use here so the fields are updated like this?

Is there such a thing as listening in the Oracle database from SQL or PL / SQL level?
I would like to change the data in a table, but I only need it if I update in a different table.
Step by step:
1. Change in table A
2. I check if the correct status is in table B
3. If it is not there, I am waiting for a change in status(this is my problem - how to wait?). Until the status changes (controlled by JOB), I can do nothing
4. The status in table B is changing, it takes the next action
It is possible by using another application, eg in Java or C#. However, I would like to ask about such possibilities without an additional programming language.
I am asking for advice.
Write the trigger on B table on update of column status and whenever the update will happen in B table you can write the code in trigger to update data in A table.
I have a table with auto increment column (ID) and have already filled my table with records. Then, after sometime I noticed that the auto increment (ID) column started from 2 instead of 1. I really wanted the count to start from 1. So, what I want to do is decrease the ID column by one for all the records using SQL statement UPDATE SET. I have used this SQL Statement on MySQL database and it worked. However, on LibreOffice base, it won't even allow me to execute Update statement saying that it is NOT a query. So, following is what I want to do.
UPDATE Accounts SET ID=ID-1;
Apparently, LibreOffice base doesn't like that sql statement. So, how can I do this?
It sounds like you tried to create a query, but that is not how to run an update command. Instead, go to Tools -> SQL and enter the following:
UPDATE "Accounts" SET ID=ID-1;
This was tested using the default HSQLDB engine.
I am working on a database used by separate applications. One of these applications is updating two fields in a table but I can't work out what one and don't have the source code for all the applications.
I am wondering if it is possible to write a log (to another table or elsewhere) to what the last update statement made against the table in question was. E.g. to record all SQL that has attempted to update the table automatically...
create a trigger before update on this table. Also create a new table. In that trigger store values before and after update in to a newly created table
I am using PostgreSQL. I have a schema 'cmp' under-which I have several tables e.g. customers,employees and etc. Every table has 'created' and 'modified' field (column). I want to update modified field with the help of trigger whenever there is any record update. I am choosing trigger for this operation but I have below issue:
I have to write trigger for each & every table individually. Is there any way I can write a trigger on a schema or a global schema which will update modified field of a particular table which caused trigger event?
I am creating a form to update my database.
I would like the user to select two options to filter the results: Month and State
Then I would like to populate a subform (in datasheet view) where the user can update the other corresponding columns (amount due, etc)
Then I would like a button that uses the imputed data and updates the main database.
I created a query to filter the results based on the 2 combo boxes. When it is populated onto the subform it will not allow editing.
How do I begin to solve this problem?
*I've tried creating a temporary table using the query results, but I cannot get the temp table to populate into the subform so that I can just write an update query to move the results from the temp table to the main database.
Thank you so much!
Your query is probably not an updateable query so it disallows editing.
To use an updateable query or temp table in your subform, you need to use VBA to handle the dynamic process:
Create temp table or run the updateable query from form's user-defined filter options.
Bound the temp table to the subform's recordsource using Recordsource (example:
Forms!MainForm!Subform.Form.Recordsource = "[TEMP TABLE]").
Requery the subform to refresh it as it will
not show immediately (example: Forms!MainForm!Subform.Requery).
If using temp table, run your update action query to migrate temp data to actual database
table. An updateable query would already connect to your actual
table so will not need an update action query.
