#ORACLE ODBC DRIVER CONFIGURATION FETCH BUFFER SIZE WINDOWS#To open the ODBC Data Source Administrator dialog box, go to the Start menu under Windows Administrative Tools, choose ODBC Data Sources: The ODBC Data Source Administrator dialog box is a Windows component. The ODBC Data Source Administrator dialog box is used to create and manage ODBC data sources. #ORACLE ODBC DRIVER CONFIGURATION FETCH BUFFER SIZE DRIVERS#Under the Drivers tab, check iif the ODBC Driver for SQL Server driver exists: Or open the ODBC Data Source Administrator dialog box: To confirm that the Microsoft ODBC drivers for SQL Server is installed, go to Control Panel and under the Program and Features find the Microsoft ODBC drivers for SQL Server: Click the Finish button to close the Microsoft ODBC drivers for SQL Server Setup window: In a few seconds, the installation of the Microsoft ODBC drivers for SQL Server finishes. #ORACLE ODBC DRIVER CONFIGURATION FETCH BUFFER SIZE INSTALL#On the Feature Selection window, select the Client Components item and click the Next button:Ĭlick the Install button on the Ready to Install the Program window to begin the installation of the Microsoft ODBC drivers for SQL Server: #ORACLE ODBC DRIVER CONFIGURATION FETCH BUFFER SIZE LICENSE#Under the License Agreement window read the license terms and if you agree, check the “ I accept the terms in the license agreement” radio button and click the Next button: msodbcsql.msi ) file and the welcome screen will appear:Ĭlick the Next button to proceed with installation. The process of installation of the Microsoft ODBC drivers for SQL Server is very simple and straightforward. ![]() Let’s install the appropriate Microsoft ODBC drivers for SQL Server. x86\msodbcsql.msi on the Windows 64-bit version), the following warning message will appear: In case that the wrong version of the Microsoft ODBC drivers for SQL Server is trying to be installed (e.g. X86\msodbcsql.msi is for the Windows 32-bit version X64\msodbcsql.msi is for the Windows 64-bit version Depending on which Windows operating system version (32-bit or 64-bit) is used, there are two versions of the Microsoft ODBC drivers for SQL Server that can be installed: Installing and configuring the Microsoft ODBC drivers for SQL Serverįrom this link, the Microsoft ODBC drivers for SQL Server can be downloaded and installed. After that, it retrieves results from the ODBC driver and formats those into OLE DB specific structures which the consumer has access to them. The provider transforms incoming OLE DB calls into ODBC calls, and transfers them on to the specified ODBC driver. MSDASQL allows OLE DB consumer applications to use ODBC drivers to connect to a data source. The diagram below explains the flow of connecting to a SQL Server database using the MSDASQL provider and a SQL Server ODBC driver. #ORACLE ODBC DRIVER CONFIGURATION FETCH BUFFER SIZE HOW TO#In this article, we will explain how to install the appropriate ODBC drivers for SQL Server, how to configure ODBC to connect to a SQL Server instance and how to create and configure a Linked Server using the ODBC driver and the MSDASQL provider to query tables on a SQL Server instance. ODBC is designed for relational data stores. Provider= OraOLEDB.Microsoft Open Database Connectivity ( ODBC) is an application programming interface ( API) designed to access data from a different of database management systems ( DBMS). ![]() This one specifies sessions to enlist in distributed transactions. The use of this property limits the processing overhead to stored procedures having one or more LOB datatype parameters. OraOLEDB requires this property to be set to TRUE, in order to fetch the parameter list of the stored procedure prior to execution. SPPrmsLOB: This property allows the consumer to specify whether one or more of the parameters bound to the stored procedures are of Oracle's LOB datatype (CLOB, BLOB, or NCLOB). However, this property must be set for all other SQLs such as INSERT, UPDATE, and DELETE. This property should not be set for commands executing SELECT statements. This information is required by OraOLEDB to detect and bind the parameters appropriately. NDatatype: This property allows the consumers to specify whether any of the parameters bound to the command are of Oracle's N datatypes (NCHAR, NVARCHAR or NCLOB). PLSQLRSet: If the stored procedure, provided by the consumer, returns a rowset, PLSQLRSet must be set to TRUE (enabled). So the properties are specified in the connection string instead. This is not possible if using the Microsofts OLE DB. Using ADO, these properties would have been set as a property on the command. ![]()
