Oracle updating recordset during cursor
The manual for versions of Connector/ODBC older than 5.2 can be located in the corresponding binary or source distribution. For example, the official My SQL formatted version number 5.0.9 may be displayed by Windows tools as 5.00.09. If you experience problems with the performance of Connector/ODBC, or notice a large amount of disk activity for simple queries, there are a number of aspects to check: For more information on how to set the query timeout on Microsoft Windows when executing queries through an ODBC connection, read the Microsoft knowledgebase document at Most programs should work with Connector/ODBC, but for each of those listed here, there are specific notes and tips to improve or enhance the way you work with Connector/ODBC and these applications. Connector/Net runs on any platform that supports the . Before installing, ensure that your system is up to date, including installing the latest version of the . Using the installer is the most straightforward method of installing Connector/Net on Windows and the installed components include the source code, test code and full reference documentation. This is a new requirement as of Connector/Net 6.6.4.Please note that versions of Connector/ODBC earlier than the 3.51 revision were not fully compliant with the ODBC specification. However, Windows tools (Control Panel, properties display) may show the version numbers as XX. The two versions are the same; only the number display format is different. Close End Sub * * (C) Copyright My SQL AB, 1995-2006 * **/ /* build command * * csc /t:exe * /out:* /r: Microsoft. With all applications, ensure that you are using the latest Connector/ODBC drivers, ODBC Manager and any supporting libraries and interfaces used by your application. You install Connector/Net through a Windows Installer ( is replaced with the version of Connector/Net you are installing. Report Source = my Report Catch ex As Exception Message Box. Message, "Report could not be created", Message Box Buttons. The following list shows steps and code fragments needed to run a Connector/Net application in a partial trust environment.
The application development section of the ODBC API reference assumes a good working knowledge of C, general DBMS, and a familiarity with My SQL. Write Line("INSERT, Total rows affected:" & _ My Command. Command Text = "INSERT INTO my_vb_net VALUES(20,'mysql')" Console. Write Line("id = " & _ CStr(My Data Reader("id")) & " name = " & _ CStr(My Data Reader("name"))) End If End While 'Catch ODBC Exception Catch My Odbc Exception As Odbc Exception Dim i As Integer Console. To String) 'Catch program exception Catch My Exception As Exception Console. To String) End Try End Sub This section provides reference material for the Connector/ODBC API, showing supported functions and methods, supported My SQL column types and the corresponding native type in Connector/ODBC, and the error codes returned by Connector/ODBC when a fault occurs. If the program works with another SQL server, include an ODBC log file where you perform exactly the same SQL statements so that we can compare the results between the two systems. For more information, see Section 22.2.3, “Connector/Net Visual Studio Integration”. The partial trust support for Connector/Net has improved rapidly throughout the 6.5.x and 6.6.x versions.
It was developed according to the specifications of the SQL Access Group and defines a set of function calls, error codes, and data types that can be used to develop database-independent applications. If you have problems importing data into Microsoft Excel, particularly numeric, date, and time values, this is probably because of a bug in Excel, where the column type of the source data is used to determine the data type when that data is inserted into a cell within the worksheet. The BDE entry requires a BDE Alias Editor that is free at a Delphi Super Page near you. There is no installer available for installing the Connector/Net component on your Unix installation. NET applications under a partial or medium trust level, you might not be able to install the Connector/Net library in the GAC.
ODBC usually is used when database independence or simultaneous access to different data sources is required. Open Database Connectivity (ODBC) is a widely accepted application-programming interface (API) for database access. The result is that Excel incorrectly identifies the content and this affects both the display format and the data when it is used within calculations. Before installing, ensure that you have a working Mono project installation. Instead, you put a reference to the library in the folder inside the project or solution.
My SQL Connectors provide connectivity to the My SQL server for client programs. When using ASP and UTF8 characters, add the following to your ASP files to ensure that the data returned is correctly encoded: To fix the problem, use any working uninstallers to remove existing installations; then may have to edit the contents of the registry. My Sql Exception ex) queries in alphabetic order, as this is the order the report will expect its source tables to be in.
APIs provide low-level access to the My SQL protocol and My SQL resources. Make sure you have a backup of your registry information before attempting any editing of the registry contents. This removes the 255 character limitation on bound parameters. Connection String = "server=127.0.0.1;uid=root;" "pwd=12345;database=test;"; try catch (My Sql. One Set Data Source statement is needed for each table in the report. This model enables application developers to focus on the business logic of their application instead of having to recreate such boilerplate items as membership and roles support.
