I need a script MariaDB which will run on many server at once.
And sometimes the table doesn´t exist.
There is a simple way to do that without "select schema"?
Try this script:
DELETE IGNORE <table> WHERE Id IN (1,4,7);
And welcome brow.

I am new to robotframework and I am trying to get the hang of the keywords of DatabaseLibrary. I am getting error at 3 of such keywords.
1) I am using rowcount keywords as below-
${rowCount} Row Count <sql query>
And I always get ${rowCount}=0 irrespective of the number of rows in my table.
2) I am using Delete All Rows From Table as below-
Delete All Rows From Table <Table_Name>
And I get ORA-00911: invalid character but if use the same table with other keywords like Query ,it works fine.
3) I am using Table Must Exist as below-
Table Must Exist <Table_Name>
And I get ORA-00942: table or view does not exist but this table is very much there.
Please help me find what am I doing wrong.
Thanks in Advance!!!
I could be wrong but I believe a colleague told me there were issues, at the very least with the Row Count keyword.
However, for all three options there are easy solutions, which you've even hinted at in your question by using Query or Execute SQL Script
1)
${result}= Query Select count(id) from table
${rc} = ${result[0][0]} #Play with this as I forget exact syntax
2) Put your delete script in a test scripts folder with your tests and call it using Execute SQL script. You could also use Query to perform a select query before and after to confirm expected states.
3) Again perform a query against the table you're expecting to be there, a simple row count on id would do for this purpose. You could set a variable based on the result and use this again later if required.
I had similar issues.
I use cx_Oracle.
With the Table Must Exist keyword my problem was the same.
I dont really understand why, but first I have to use Encode String to Bytes keyword.
And I need to use a DatabaseLibrary 0.8 at least, because earlier versions didnt have solution for cx_Oracle. These solved this issue for me.
But with Delete all rows from table I still have problems.
Because this keyword puts a ; at the end of the line and it passes on that line to execute query if I understand weel, so it still causes an ORA-00911 error for me.
With Execute Sql String and the command DELETE FROM tablename you can have the same results, but it will work this way.
I hope it helps a little
Hi Guys I am running an Oracle DB and I have to Write the Schema(Owner) name before selecting the Table. I find this Quite Unnecessary especially when am Logged in as the Table Owner Like:
select * from MUNGAI.Employees;
When am Actually Logged in as user MUNGAI the same Who Created the table. I want to be able to select like:
select * from Empployees;
From this I get the Error On Toad....On SQLDEVELOPER I get No Error and I want to Use TOAD
ORA-00942: table or view does not exist
Any Ideas on How to Achieev this??
I have to Write the Schema(Owner) name before selecting the Table.
No, you don't have to. Why do you think so? Did you even try it?
When you are logged in as the owner of the table you do not have to specify the schema.
Any Ideas on How to Achieev this??
Yes, simply write
select * from Employees;
Again: this works if - and only if1)) - you are logged in as MUNGAI.
1) leaving things like public synonyms aside
I have created a database "MyDB.sqlite" using the command line sqlite3 MyDB.sqlite in a specific folder(my desktop) and then created a table "tbl11" using create table syntax. I am able to insert record and can check the inserted records.
But when I exit command (terminal in Mac) line and re enter I can't see my database and tables in that folder. I guess this database and table are temporary by default. I even check the .databases command to see the database, but I can only see two database main!
please help!
Be sure to finish off with COMMIT; :-)
For practice, work through the short working example at http://souptonuts.sourceforge.net/readme_sqlite_tutorial.html
Good luck.
I want a debug function to do this, but I'm unaware of whether one already exists. Going through and using 'drop table' for each of my tables will be a pain.
Help appreciated.
Since the database is just one file, you can indeed just erase it. If you want something more automatic, you can use the following to do it all programmatically:
Recover your schema:
SELECT group_concat(sql,';') FROM sqlite_master;
Disconnect from the database
Delete the database file
Create your schema again with what was returned from the above query
If you used any particular options for your original database (page_size, etc), they will have to be declared manually as well.
to "drop database" for sqlite, simply delete the database file (and recreate if needed)
I'm unable to retrieve the latest inserted id from my SQL Server 2000 db using a typed dataset in asp.NET
I have created a tableadapter and I ticked the "Refresh datatable" and "Generate Insert, Update and Delete statements". This auto-generates the Fill and GetData methods, and the Insert, Update, Select and Delete statements.
I have tried every possible solution in this thread
http://forums.asp.net/t/990365.aspx
but I'm still unsuccesfull, it always returns 1(=number of affected rows).
I do not want to create a seperate insert method as the auto-generated insertCommand perfectly suits my needs.
As suggested in the thread above, I have tried to update the InsertCommand SQL syntax to add SELECT SCOPY_IDENTITY() or something similar, I have tried to add a parameter of type ReturnValue, but all I get is the number of affected rows.
Does anyone has a different take on this?
Thanks in advance!

I decided to give up, I can't afford to waste any more time on this.
I use the Insert statement after which I do a select MAX(id) query to hget the insert ID
If anyone should have a solution, I'll be glad to read it here
Thanks

I successfully found a way to get the incremental id after insert using my table adapter.
My approach is a little different, I'm using a Store procedure to make the insert, so my insert command has all the values but the ID, I made the sp return the ID just calling:
SET #ID=SCOPE_IDENTITY()
and then
COMMIT TRAN
and last line will be
RETURN #ID
Then I searched my table adapter parameters for InsertCommand and set the #RETURNVALUE to the column of the incremental ID of the table, so when it's executed automatically put the return value on the id field.
Hope this help
You need to tell your table's table-adapter to refresh the
data-table after update/insert operation.
This is how you can do that.
Open the properties of TableAdapter -> Default Select Query -> Advnaced options. and Check the option of Refresh the data table. Save the adapter now. Now when you call update on table-adapter, the data-table will be updated [refreshed] after the update/insert operation and will reflect the latest values from database table. if the primary-key or any coloumn is set to auto-increment, the data-table will have those latest value post recent update.
Now you can Call the update as TableAdapterObj.Update(ds.dataTable);
Read latest values from the DataTable(ds.dataTable) coloumns and assign respective values into the child table before update/insert. This will work exactly the way you want.
