What is oracle rdb driver

For example, if the error message does not contain the [Ora] prefix shown in the following format, the error is an Oracle ODBC Driver error and should be self-explanatory. Although the error message contains the [Ora] prefix, the actual error may be coming from one of several sources. If the error message text starts with the following prefix, you can obtain more information about the error in the Oracle server documentation.

Format of the Connection String. Reducing Lock Timeout in a Program. Linking with odbc Information About rowids. The following table describes keywords that can be included in the connection string argument of the SQLDriverConnect function call.

Missing keywords are read from the Administrator entry for the data source. Values specified in the connection string override those contained in the Administrator entry. Sets the token size to the nearest multiple of 1 KB bytes beginning at 4 KB bytes. If the following keyword is specified in the connection string, the Oracle ODBC Driver does not read values defined from the Administrator:.

Connecting to an Oracle Data Source for all users. For more information, see the Oracle Net Services documentation. The Oracle server waits indefinitely for lock conflicts between transactions to be resolved.

Reducing Lock Timeout for more information on specifying a value in the oraodbc. For Windows platforms, when you link your program, you must link it with the import library odbc However, the rowid value must be presented in a parameter marker.

Oracle reference cursors Result Sets allow an application to retrieve data using stored procedures and stored functions. The ODBC syntax for calling stored procedures must be used. The following identifies how to call the procedure or function without a package and within a package. The package name in this case is RSET. For example, assume procedure Example2 is defined to have four parameters.

Parameters 1 and 3 are reference cursor parameters and parameters 2 and 4 are character strings. The call is specified as:. Migrated procedures are often reorganized and created in schemas in one of these ways:. All procedures defined in one SQL Server database are migrated to the schema named with that database name.

To support these three ways of organizing migrated procedures, you can specify one of these schema name options for translating procedure names. Object names in the translated Oracle procedure call are not case-sensitive. The symbols for the new attributes are defined in the file sqora. This attribute is necessary for the ODBC application to determine which connection the failure event is taking place on. Null is returned if the attribute has not been set.

The failure events map directly to the events defined in the OCI programming interface. The list of possible events is:. Use this option when you migrate any third party ODBC application to Oracle Database and you want to use implicit results functionality as supported by the previous vendor. Oracle Database Globalization Support Guide for information about Datetime data types and time zone support.

Implements ODBC support for implicit results. Unicode Functions in the Driver Manager. Data loss is possible when the Driver Manager is converting from Unicode to the local code page. An ODBC application developer need not explicitly call entry points with the suffix.

String arguments are converted from Unicode to the local code page. The text of the SQL statement parameter is converted from Unicode to the local code page. Convert return parameters that are character data from the local code page to Unicode.

In this case, the Oracle ODBC Driver uses the knowledge it has about the data type of the column as defined in the database to determine how to best default to fetching the column through OCI. The driver could default to receiving the column as Unicode, however, this may result in as many as two unnecessary conversions. The default encoding of the Oracle client is used when fetching data. Example 1: Connection to Database.

Example 2: Simple Retrieval. Example 4: Simple Update. The following example retrieves the employee names and the job titles from the EMP table. This example shows how to update data. This example may be the most complicated case to update and retrieve data for long data, like CLOB , in Oracle.

This section describes some general programming tips to improve the performance of an ODBC application. Enable connection pooling if the application will frequently connect and disconnect from a data source. Reusing pooled connections is extremely efficient compared to reestablishing a connection. Minimize the number of times a statement must be prepared. Where possible, use bind parameters to make a statement reusable for different parameter values.

Preparing a statement once and executing it several times is much more efficient than preparing the statement for every SQLExecute. This topic discusses performance implications of the following ODBC data source configuration options:.

Enable Result Sets. Enable Closing Cursors. Enable Thread Safety. Fetch Buffer Size. This option enables the support of returning result sets for example, RefCursor from procedure calls. The default is enabling the returning of result sets. The ODBC Driver must query the database server to determine the set of parameters for a procedure and their data types to determine if there are any RefCursor parameters.

This query incurs an additional network round trip the first time any procedure is prepared and executed. Enable LOBs. The application can reopen the cursor by executing the statement again without doing a SQLPrepare again. A typical scenario for this is an application that is idle for a while but reuses the same SQL statement.

Connection" connection. Open The idea is to query via oracle. You can use the Oracle database's generic connectivity feature to connect to non-Oracle databases with Oracle Discoverer. For Discoverer, the major difference between using the Oracle database generic connectivity feature and using ODBC drivers to connect to a non-Oracle database is as follows:. Using Discoverer with the Oracle database's generic connectivity feature rather than the native ODBC drivers when connecting to a non-Oracle database, has the following advantages:.

Compliance varies with both databases and ODBC drivers. For example, you can create a single business area with folders based on tables held in Sybase, DB2 and Oracle databases. An end user query can return data joined across multiple databases. Discoverer's query prediction uses query statistics that are generated when end users run queries and which are saved in the EUL.

Discoverer uses the batch scheduler in the Oracle database. The data is brought into the Oracle database and the function is applied. This enables access to very powerful analytical functions against ODBC data.

Which Discoverer features are partially supported by Oracle Rdb? This section includes the following topics: "What are the software requirements for Discoverer to support non-Oracle databases using native ODBC drivers?

If the view was not automatically created, you must: create the view manually in the EUL owner database user alongside the standard EUL objects grant the same permissions on the view as on other read-only objects in the EUL e. Discoverer support for non-Oracle databases using generic connectivity Discoverer fully leverages the Oracle8 i database generic connectivity feature.

This section includes the following topics: "What is generic connectivity? For Discoverer, the major difference between using the Oracle database generic connectivity feature and using ODBC drivers to connect to a non-Oracle database is as follows: with generic connectivity, the EUL is stored in the Oracle database with ODBC drivers the EUL is stored in the non-Oracle database How to set up generic connectivity For more information about how to set up generic connectivity, see the Oracle9i Heterogeneous Connectivity Administrator's Guide.

OracleDriver" I have installed the Oracle Client and copied ojdbc6. I have done some search on the internet for resolution of similar issues - but could not yet find something that would work.

Is there a different directory this should go to, or is there some trick to setting it up? Please advise. Join Date Jun Posts 5,
