MySQL to PL/SQL Conversion.

guys,
I have a client that has around 200 Stored procedures, functions and triggers written in MySQL. They are attempting to convert to Oracle PL/SQL
Has anyone taken this effort and all experiences are greatly appreciated.
Please share the pitfalls and the process followed.
Thanks
Srinivas

Couldn't resist.... ;)
Two men were arguing about the slowness of their 500GB MySQL Database.
"It is slow because of a poor table design," stated the first man.
"No, it is slow because of poor SQL," contended the second.
An Oracle master, who happened to be walking by, overheard the debate and interrupted them.
"Neither the table design nor the SQL are to blame," he said,
"It is slow because it is MySQL."

Support for mysql or ms sql server ?

Does sunone support mysql or ms sql server, I keep getting the following when I try to deploy an entity bean using either database.
Deployment Error -- Error while running ejbc -- Fatal Error from EJB Compiler -- -- java.lang.RuntimeException: The schema file sequence, does not contain a table named SEQUENCE
I'm using the dbschema generated by Forte, is there some hand editing I need to do to get it to work? I'm still confused why this schema is necessary, never had to go through such an annoying process with IAS or weblogic.
Here's my schema:

Thanks for the help, the migration tool translated all my table names and columns names into caps, lowercasing these babies in the sun-cmp-mappings.xml fixed the problem.

Not sure as we don't have any tables and data to work with, but firstly...
a) format your code to make it easier to see what's going on
b) don't mix ansi joins with regular joins
c) treat DATEs as DATEs
d) Table alias names don't use the "AS" keyword

Date syntax for MySql query in SQL Reporting Services

I am currently trying to link a mysql Stored Procedure to a Microsoft SQL Reporting Server. It is coming up with a Syntax error. I believe this is down to the
Date_from and Date_to Parameters. The query is below any help would be appreciated
DELIMITER $$
USE `mydb`$$
DROP PROCEDURE IF EXISTS `DTI`$$
CREATE DEFINER=`linkeduser`@`%` PROCEDURE `DTI`(IN date_from DATETIME,
IN date_to DATETIME)
BEGIN
SELECT title,gender,firstname,lastname,address1,town,postcode,dob,IF(co.start_date = '00-00-0000', '', CAST(DATE(co.start_date) AS DATE)) AS 'StartDate'
FROM cf_user AS us
JOIN ca_compliance AS co ON co.user_id = us.user_id
WHERE co.start_date BETWEEN date_from AND date_to;
END$$
DELIMITER ;

Hello，
The dataset query runs on the external data source.
In your case, you create a report by retrieve data from MySQL database with a stored procedure. The stored procedure will run on MySQL Server and return the result in the Report designer or Report Builder. To solved this issue, please execute the stored
procedure on the MySQL database and check the syntax error.

Switch from MySQL to MS SQL Server, Query not working

I'm sure there is a simple setting somewhere for this, but cannot seem to find it and really would appreciate some assistance. Have an application which uses JDBC to connect to a MySQL DB to run the following query without an issue:
SELECT * FROM users
This returns the desired results. Changed to connect to MS SQL Server 2000 using the JDBC-ODBC bridge and the same query returns no results. The problem, SQL Server wants this query instead:
SELECT * FROM [users]
I don't want to have to change queries depending on the DB, as that is supposed to be one of the advantages of JDBC. Is there a setting in MySQL (or the JDBC driver) to have it work correctly if I pass table names in []? Or is there a setting in MS SQL Server (or in the JDBC, or ODBC) to have it accept queries without the []?
Or is there a different approach that I'm missing which would avoid this whole problem?
Thanks,
Matt

I suspect your database definitions are different. It has nothing to do with your java code.
The bracket syntax is used to indicate the more standard quoted identifiers in standard SQL.
Thus you could do this in oracle and in MS SQL Server...
SELECT * FROM "users"
I suspect that the above will work for your MS SQL Server database and will not work for your Oracle database. However if you created the table in oracle and specifically used "users" (with the double quotes around the name) when creating the table then it would work.
Of course if the database definitions are different it means you must use different SQL for each. Just as if the name of the table was 'other' rather than 'users'.

Import / Export MySQL database in SQL Developer

Hello,
I have version 3.1.2.704 of SQL Developer Data Modeler and version 3.2.09 of SQL Developer installed.
When I´m adding a new connection in SQL Developer, I can choose the MySQL tab an create a connection to a MySQL database.
The connection test was successful and I can see all tables.
I use the same JDBC driver for SQL Developer and SQL Developer Data Modeler (mysql-connector-java-5.0.4-bin.jar).
But there are two problems.
1. First there is an problem when I want to import from a MySQL database (SQL Developer -> File -> DataModeler -> Import -> DataDictionary).
After choosing the MySQL connection and pressing the next button an error occurs: CONNECTION_TYPE
What is the reason?
2. In SQL Developer Data Modeler I have not the CONNECTION_TYPE problem. But when I want to export DDL, there is no MySQL type selectable, although there is working connection to the MySQL Database. It´s the same in SQL Developer.
What is the reason?

Import / Export MySQL database in SQL Developer Data Modeler

Hello,
I have version 3.1.2.704 of SQL Developer Data Modeler and version 3.2.09 of SQL Developer installed.
When I´m adding a new connection in SQL Developer, I can choose the MySQL tab an create a connection to a MySQL database.
The connection test was successful and I can see all tables.
I use the same JDBC driver for SQL Developer and SQL Developer Data Modeler (mysql-connector-java-5.0.4-bin.jar).
But there are two problems.
1. First there is an problem when I want to import from a MySQL database (SQL Developer -> File -> DataModeler -> Import -> DataDictionary).
After choosing the MySQL connection and pressing the next button an error occurs: CONNECTION_TYPE
What is the reason?
2. In SQL Developer Data Modeler I have not the CONNECTION_TYPE problem. But when I want to export DDL, there is no MySQL type selectable, although there is working connection to the MySQL Database. It´s the same in SQL Developer.
What is the reason?

Hi,
Data Modeler does not explicitly support import from MySQL databases, although you can use a JDBC connection to do this.
Philip described how to set this up in forum message How to connect mySQL for reverve engineering
There is no MySQL tab in Data Modeler - you should use "JDBC-ODBC Bridge" - "other third party Driver".
Set URL like : jdbc:mysql://localhost:3306/database_name
driver Class: com.mysql.jdbc.DriverAlso Data Modeler does not support generation of DDL for MySQL.

MySQL database with SQL Toolkit

Hi,
we are using CVI 2012 and the SQL Toolkit 2.2 and we want to connect to a MySQL database.
The MySQL database was created with MySQLServer. When we try to connect with DBConnect we get an error.
How can we connect the MySQL Database?
What do we have to type in the connection string in DBConnect? Is it the name of the database, the path to the database or anything else?
Does any one have experience with the SQL toolkit?
Thanks in advance
Oliver
Solved!
Go to Solution.

You need to install the mysql connector odbc and then create an ODBC dns for your database.

JDBC MySQL INET_NTOA() Function & IP Conversion

Firstly,
Using the MySQL connector, any idea's why the select statement does not work ?
The MySQL Database Table:
mysql> select INET_NTOA(IPV4) from pptip;
+-----------------+
| INET_NTOA(IPV4) |
+-----------------+
| 255.255.255.255 |
+-----------------+
1 row in set (0.00 sec)
SELECT * FROM PPTIP;
+------------+
| ipv4       |
+------------+
| 4294967295 |
+------------+
1 row in set (0.00 sec)Works perfectly in MySQL command line but I receive the following java runtime error:
SQLException: Column 'IPV4' not found.
SQLState: S0022
try {
            Connection connection = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/ppt","root", "password");
            System.out.println("Creating score card database");
            String sql = "SELECT INET_NTOA(ipv4) FROM pptip";
            Statement stat = connection.createStatement();
            ResultSet rs = stat.executeQuery(sql);
            while (rs.next()) {
                System.out.println( rs.getString("IPV4"));
            // Close everyting
            rs.close();
            stat.close();
            connection.close();
        } catch (SQLException ex) {
            // handle any errors
            System.out.println("SQLException: " + ex.getMessage());
            System.out.println("SQLState: " + ex.getSQLState());
            System.out.println("VendorError: " + ex.getErrorCode());
        }Thanks for your help..
Rob

Thanks for your response, but MySQL statements are not case sensitive.
The actual error comes from the SQL Comment:
String sql = "SELECT INET_NTOA(ipv4) FROM pptip";
Both
String sql = "SELECT ipv4 FROM pptip";
and
String sql = "SELECT IPV4 FROM pptip";
works fine.. the INET_NTOA function does not.
I suspect the driver does not support this... not 100%.

T-SQL - PL/SQL conversion: insert into ... select problem

Hi!
If I have an insert into ... select statement in T-SQL without a 'from' clause:
bq. insert into sometable (foo, bar) \\ select 5, case when @bar=5 then 4 else 3 end
its translation is:
bq. INSERT INTO sometable \\ ( foo, bar ) \\ VALUES ( 5, CASE \\ WHEN 5 = 5 THEN 4 \\ ELSE 3 \\ END col );
and I got: ORA-00917: "missing comma" for that. I'm not sure if it's a bug in the migration code, or is there a trick so that I can use 'CASE' in an insert into .. values statement somehow?
Zoli

You have to remove the column name. I just simplified your test case to check and it's working:
CREATE TABLE test(
id NUMBER
INSERT
INTO test(id)
VALUES(CASE WHEN 5=5 THEN 4 ELSE 3 END)
SELECT *
FROM test
;C.

OBIEE: logical SQL to Physical sql conversion

Hi,
Is there any way i can get the physical sql from logical sql ( Apart from reading log file).. I am looking something like JAVA api which does that for us.. Do we have any mapping table which stores this mapping.
Does the OBIEE provides any Java API.
Appreciate your help in advance.

Hi Experts,
Please help on this.

SQL conversion of MEMO field

I have a web site that builds pages based on content in an
Access DB. One of the fields is MEMO and contains body copy for the
page (usually 300-400 words per record). This bodyCopy field is
HTML tagged IN the record (in case that matters). So I import the
whole database into SQL. Fine. The pages display ok - All the data
in the bodyCopy field is STILL in there, I can see it on the
webpages. BUT, I cannot see, or edit the cells in SQL Enterprise
manager. If I add a new record similar bodyCopy pastes are
truncated. SQL converted the MEMO field to ntext(16). I have tried
text(16) and nvarchar(8000) with the same results. I need to be
able to edit the existing cells, and input similarly sized data
chunks in with new records...
Can anyone shed some light on this issue?

SQL is a bit different in managing the data directly than
Access was.
ntext should be fine for any previous memo fields.
If it tells you that you cannot edit the cells, it is usually
because the Key has not been defined. Importing from Access will
bring in all your data, but it won't necessarilly apply the Key
identifier. Without a key it won't let the data be edited, at least
not directly.
If it is showing up in the web page OK then the data would
not appear to be truncated, just not all viewable in the SQl
listing. If you try to enter too much data into a field in SQL it
usually will simply refuse to do it.
Have ou tried connecting to the SQL server via Access (ADP)?
If you have been used to Access all this time, it can be a really
nice way of working between the two and gives you a familiar way of
doing things.

XML to SQL conversion using OracleXML putXML

Hi,
How many rowTag values can I use when I use OracleXML putXML ? I have an XML file in the following format.
I have to use "ABC" as rowTag. What Can I do with "GRANT_ROW" ? I have a table with
R_DATE and
GRANT columns
where GRANT is an object type with elements
NAME and ATYPE.
Thanks.
<?xml version = '1.0'?>
<EXCH>
<ABC num="1">
<R_DATE>5/21/2003 0:0:0</R_DATE>
<GRANT>
<GRANT_ROW num="1">
<NAME>GUNACAR</NAME>
<ATYPE>TE</ATYPE>
</GRANT_ROW>
<GRANT_ROW num="2">
<NAME>GUNACAR</NAME>
<TYPE>TE</TYPE>
</GRANT_ROW>
</GRANT>
</ABC>
</EXCH>
I get the following error when I run
java OracleXML putXML ....
oracle.xml.sql.OracleXMLSQLException: 'The XML element tag 'GRANT_ROW'
does not match the name of any of the columns/attributes of the
target database object.' encountered during processing ROW element 0.
Thanks....
