In Snowflake sql can we call a Oracle's Sequence function just like how we can do a look up in Pentaho and use the Oracle sequence generator. Is it possible in Snowflake ?
As stated in the comments you may use Snowflake's Sequence feature, see below links.
CREATE SEQUENCE: https://docs.snowflake.com/en/sql-reference/sql/create-sequence.html
Querying sequences: https://docs.snowflake.com/en/user-guide/querying-sequences.html
But you have to be beware of possible differences. For example is it possible to use CURRVALL in Oracle to extract the current value. This is not implemented in Snowflake.

Would you mind help me how I can load and fill a word template dynamically via oracle form or plsql codes?
I am using oracle 10g.
The fastest way to have a possibility of generating MS Word documents from Oracle (and pl/sql) is to use an additional tool. Here is a comparison of some of them for Oracle and APEX https://explorantum.com/ords/r/w/explorantum/oracle-report-tool-comparison
Is there any way we can extract data from oracle tables to multiple sheets in an excel?
For example: I have two tables checkpoints and hold. I want data from checkpoints to go to sheet1 of MS excel and data from hold to go to sheet2.
Is this possible to implement in oracle?
Oracle version: Oracle 11G
Edit:
I would like to implement this using PL/SQL. This code will be executed as a batch job.
If the spreadsheet you want to generate is very simple (i.e. just cells with data, and multiple sheets) you could try the Excel generation API in the Alexandria PL/SQL Library - just grab XLSX_BUILDER_PKG and its dependencies (I don't think there are many) and it should do the job.
I've used it myself to generate simple spreadsheets in XLSX format, and it's all in PL/SQL. It returns the results in a BLOB, and there's another routine in the library for spitting that out with UTL_FILE, if you need the result on the database server.
Of course it is possible, but it depends how do you want that to be done.
1) If you have a reporting tool (Jasper Reports, Oracle BI) you can use that tool to create a report and export the data.
2) If you have a developer tool (Toad, SQL Developer) you can export the two tables "by hand".
3) If you know how to write code, than you can use a API to create the Excel file and populate it with the data. You can use PL/SQL, PHP, C, C++ or almost any other language, it just needs a Oracle API and an Excel API.
There is PL/SQL package that is able to create Excel document with multiple sheets and put data from SQL query to separate sheets.
Please see example below:
BEGIN
ORA_EXCEL.new_document;
ORA_EXCEL.add_sheet('Employees');
ORA_EXCEL.query_to_sheet('select * from employees');
ORA_EXCEL.add_sheet('Departments');
ORA_EXCEL.query_to_sheet('select * from departments', FALSE);
ORA_EXCEL.add_sheet('Locations');
ORA_EXCEL.query_to_sheet('select * from locations');
-- EXPORT_DIR is an Oracle directory with at least
-- write permission
ORA_EXCEL.save_to_file('EXPORT_DIR', 'example.xlsx');
END;

I am working on migration project of Oracle to Teradata.
The tables have been migrated using datastage jobs.
How do I migrate Oracle Views to Teradata?
Direct script copying is not working due to SQL statements difference of both databases
Please help?
The DECODE() Oracle function is available as part of the Oracle UDF Library on the Teradata Developer Exchange Downloads section. Otherwise, you are using the DECODE function in your example in the same manner in which the ANSI COALESCE() function behaves:
COALESCE(t.satisfaction, 'Not Evaluated')
It should be noted that the data types of the COALESCE() function must be implicitly compatible or you will receive an error. Therefore, t.satisfaction would need to be at least CHAR(13) or VARCHAR(13) in order for the COALESCE() to evaluate. If it is not, you can explicitly cast the operand(s).
COALESCE(CAST(t.satisfaction AS VARCHAR(13)), 'Not Evaluated')
If your use of DECODE() includes more evaluations than what is in your example I would suggest implementing the UDF or replacing it with a more standard evaluated CASE statement. That being said, with Teradata 14 (or 14.1) you will find that many of the Oracle functions that are missing from Teradata will be made available as standard functions to help ease the migration path from Oracle to Teradata.
Does anybody know if Common Table Expressions and User-defined functions (not from Java) are supported on Sybase 12.5? I'm trying but could not seem to make these work. Thanks guys.
Both are not supported by ASE 12.5
You can use stored procedure instead of functions. I am not sure about what you are referring to by saying common table expressions
Sorry I have to disagree. Microsoft SQL Server is based on Sybase 7.0. So there may not be Common Table Expressions and User-Defined Functions, there are equivalent ways to do the same thing.
For example CTE can be done either in nested queries or via temp tables using a number sign (#) in front of the table name.
For User Defined Functions, create a stored procedure with simple SQL code and call it via the exec function for example "exec my_sql_code". This allows nesting of stored procedures.
Good SQL, good night.
I have two schemas: A and B (Oracle 9). At the A there is a dblink to B. At the B there is a package, that i calls from A. Procedures in B package can returns varying count results and i think that returning a collection is a better way for this reason.
create type B.tr_rad as object (
name varchar2(64)
,code number
,vendor number
,val varchar2(255)
,num number
);
create type B.tt_rad as varray(256) of B.tr_rad;
But from A scheme I cannot use tt_rad type because using SQL-types by dblink is not supported. DBMS_SQL is not supported cursors. Create types with same OID is impossible.
I think to use temporary tables. But firstly it is not that good (after the remote function returns the value, calling side must select collection from remote table). And there are fears of a slowdown of work with temporary tables.
Maybe who knows the alternative interaction?
I've had similar problems in the past. Then I came to the conclusion that fundamentally Oracle's db links are "broken" for anything but simple SQL types (especially UDT's, CLOBS may have problems, XMLType may as well). If you can get the OID solution working then good luck to you.
The solution I resorted to was to use a Java Stored procedure, instead of the DB Link.
Characteristics of the Java Stored Procedure:
Can return a "rich set of types", just about all of the complex types (UDT's, tables/arrays/varrays) see Oracle online documentation for details. Oracle does a much better job of marshalling complex (or rich) types from java, than from a DBLink.
Stored Java can acquire the "default connection" (runs in the same session as the SQL connection to the db - no authentication issues).
Stored Java calls the PL/SQL proc on the remote DB, and the java JDBC layer does the marshaling from the remote DB.
Stored Java packages up the result and returns the results to the SQL or PL/SQL layer.
It's a bit of work, but if you have a bit of java, you should be able to "cut and paste" a solution together from the Oracle documentation and sample.
I hope this helps.
See this existing discussion
referencing oracle user defined types over dblink
An alternative interaction is to have one database with schemas A and B instead of two databases with a database link.
My solution.
On the side B i create temporary table like the collection record. At the A side i have a DBMS_SQL wrapper that calls procedure over dblink. This procedure writes result collection in the temporary table. After successful completion remote procedure i select results from remote temporary table and transform it to local collection type.
Limitations
1. the need for permanent object synchronization.
2. impossibility use A-side procedure (that call remote procedure) in SQL query.
3. the complexity of using.
