Lets move on and create a cursor and see how it works in DB2. Now lets create a stored procedure that has parameters in it.Example 2 illustrates a stored procedure having an input parameter. You can use MySQL cursors in stored procedures, stored functions, and triggers. Example 2: Sample Stored Procedure with input parameters in it.
#Store procedure with cursor in adventureworks2012 example update
However, any change that made to the data from other connections will affect the data that is being used by an asensitive cursor, therefore, it is safer if you do not update the data that is being used by an asensitive cursor. An asensitive cursor performs faster than an insensitive cursor because it does not have to make a temporary copy of data.
An asensitive cursor points to the actual data, whereas an insensitive cursor uses a temporary copy of the data.

It might look strange at the database connection part, but that is just because it connects through a Glassfish web server connection pool and not straight through JDBC.Īlso it must look like a lot of code, but with the right IDE, such as Netbeans, 90% of it is written for you.Summary: in this tutorial, you will learn how to use MySQL cursor in stored procedures to iterate through a result set returned by a SELECT statement. I see no reason why you can’t just execute it.īelow is a test which returns a list for a dropdown selection into a web page retrieved from a MySQL database. ("SQL State: %s\n%s", e.getSQLState(), e.getMessage()) Here is an example: USE AdventureWorks2012 GO - Declare and using a READONLY cursor - DECLARE AllProductsCursor CURSOR READONLY FOR SELECT ProductID FROM Production.Product WHERE ListPrice > 200.0 ORDER BY ProductID DECLARE ProductID INT OPEN AllProductsCursor FETCH NEXT FROM AllProductsCursor INTO ProductID DECLARE RC int DECLARE CheckDate datetime '20070205. Obj.setCreatedDate(createdDate.toLocalDateTime()) Timestamp createdDate = resultSet.getTimestamp("CREATED_DATE") CREATE TYPE statement to create a strongly-typed cursor based on a row data type specification. This example shows the following: CREATE TYPE statement to create a ROW data type. Referencing examples that demonstrate cursor variable use is a good way to learn how and where you can use cursor variables. Then every record is compared with the condition and the product having rating greater than 8 will be inserted into the NewProducts table. An Oracle stored procedure can return a cursor to the caller, for example: Oracle: - Get list of employees for the specified department CREATE OR REPLACE PROCEDURE getEmployeesByDept ( pdeptno IN emp. After that, when the cursor is opened, we are fetching the rows one by one. String name = resultSet.getString("NAME") īigDecimal salary = resultSet.getBigDecimal("SALARY") Cursor variable use within an SQL procedure. Firstly, the cursor in the stored procedure will retrieve all the records from the Products table. USE AdventureWorks2012 GO IF OBJECTID ( 'dbo.uspCurrenc圜ursor', 'P' ) IS NOT NULL DROP PROCEDURE dbo.uspCurrenc圜ursor GO CREATE PROCEDURE dbo.uspCurrenc圜ursor Currenc圜ursor CURSOR VARYING OUTPUT AS SET NOCOUNT ON SET Currenc圜ursor CURSOR FORWARDONLY STATIC FOR SELECT Currenc圜ode, Name FROM Sales.
ResultSet resultSet = (ResultSet) cs.getObject(2) get refcursor and convert it to ResultSet In the script you have to replace the parameter value with question mark (). In this the variable storedProc has the stored procedure execution script.

cs.registerOutParameter(2, Types.REF_CURSOR) Ĭs.registerOutParameter(2, OracleTypes.CURSOR) Here is the sample python code to execute the stored procedure and fetch a few rows from a table and print the data. Statement statement = conn.createStatement() ĬallableStatement cs = conn.prepareCall(runSP) Try (Connection conn = "system", "Password123") The definition of stored procedure is stored in database and the parameters are stored in data dictionary tables. + " SELECT * FROM EMPLOYEE WHERE NAME LIKE p_name || '%' " Get Sample Teradata Stored Procedure With Cursor Background. String createSP = "CREATE OR REPLACE PROCEDURE get_employee_by_name( "
