I've written an oracle query which executes fine against Oracle 11g DB (I wrote it in PL/SQL developer). But when I try to copy/paste it into Microsoft Query as SQL, it fails with ORA-00900: invalid SQL statement.
Is there a list of what can be included in query for Microsoft Query to be treated as valid? In my query I use a lot of SQL modelling - is it not supported?
I don't believe any of the MODEL features of Oracle are supported by any MS SQL variant.
But as that is an ORA message you are still executing against Oracle, I have to assume that the connection is messing with the SQL. Why do you need to issue the sql through MS Query?
(Perhaps you could define a view/function/proc in Oracle with your model syntax, and then use that object through MS Query)

I'm working on Sql server to Snowflake migration project,So i pointed ssrs reports to Snowflake data source and converting sql queries as per snowflake,but i'm not able to get how can we write queries for parameterized reports.Example select * from Student where Std_id=#id,want to convert to snowflake query.
You can use SQL variables:
https://docs.snowflake.com/en/sql-reference/session-variables.html
or Snowflake Scripting Variables:
https://docs.snowflake.com/en/developer-guide/snowflake-scripting/variables.html
I think the SQL variables would be helpful in your case, but Snowflake Scripting variables would be more similar to your SQL Server # variables.
I made a relational model in Oracle SQL Developer and I want to make tables in MySQL Workbench. I generated the DDL script in SQL Developer and copied it in MySQL Workbench. I found out that the copied queries are not in correct syntax. I tried different options in SQL Developer to generate script and none of them were in MySQL syntax.
Is there a way to generate DDL script from a model, which is made in SQL Developer, for MySQL?
There is no straight query generation for MySQL in oracle SQL developer. You should use such a sites for your purpose to convert them into MySQL syntax or use tools for automatic converting.
Is there a way to parse code in SQL Developer (oracle) without actually touching tables/packages data like you can do with "parse" option in SQL Management studio?
There is no option to merely parse the SQL statement to validate the syntax.
You could choose the "Explain Plan" option (F10 in the Windows version of SQL Developer), that will validate the syntax as part of generating the query plan. If there is a syntax error, you'll get the error message when you attempt to generate the plan but you generally won't get the line and column of the error which makes debugging more challenging.
I was looking for this right now and couldn't find an option in Oracle SQL Developer.
I know a service called SQL Fiddle that can help in such situations where one needs to test/parse/validate an adhoc PL/SQL script. Using SQL Fiddle you can do this:
Select Oracle 11g R2 (as available right now) in the dropdown and type your script in the left text area. Press Build Schema button. If your script is valid then it'll show you Schema Ready message like this:
I'm refactoring a c# application and optimizing some queries. The app supports Microsoft SQL server and Firebird.
I can't seem to find any information regarding issuing multiple select statements in Dynamic SQL on Firebird.
For example this is valid for Microsoft SQL server:
"SELECT * FROM ATABLE; SELECT * FROM ANOTHERTABLE;"
However Firebird calls invalid token on the semicolon.
Note this is called from c# code using the ADO.NET Firebird driver.
Firebird does not support multipel select within the same command
I have a database schema generated in a text file (DDL - MS Access compliant).
Where is the option in MS Access to import that schema into an empty database ?
I'm not aware of any import for DDL.
However, DDL contains the definition for the schema.
You simply have the execute DDL as you would any query.
Either create a query, put it in sql mode, paste your ddl, and execute
or....
Create a VBA Sub to essentially do the same: currentdb.execute SQL
Good Luck
To execute a SQL DDL in the SQL View of a Query object, you may need to change the Access user interface to ANSI-92 Query Mode. While the 'traditional' query mode (ANSI-89 Query Mode) supports a SQL DDL syntax it is very limited.
The Access database engine can only execute one SQL statement (DML, DDL or DCL) at a time. To execute a SQL script consisting of multiple SQL statement, you need something to parse individual SQL statements, so it really helps if your script has semicolon ; characters separating them, then execute each statement on at a time i.e. synchronously. If you are doing this in VBA code you are better off using ADO because it always uses ANSI-92 Query Mode.

I have been very succesful with reverse / forward engineering MS Access databases with Dezign for Databases by Datanamic. It reads all kinds of DDL scripts (from almost all available database) and can translate between different databases. There is a free trial available.
