I will be glad to provide you with the additional options available that you can utilize to get the issue resolved. Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. The Arabic characters look correct in Toad but when I pull it into Excel, they just come up as questions marks "? Excel gets the data just fine, but it is using the wrong encoding to interpret it, hence the "?

Try googling how to set your encoding in Excel to display Arabic characters. Add all the credentials and this will create driver and add it your Data Sources going forward. I have upgraded my system to windows 7 recently.

I need to create a odbc connection using microsoft odbc drivers for oracle. Schema , which is the translated Oracle subprogram assumed to be defined in the user's default schema. However, if all subprograms from the same SQL Server database are migrated to the same Oracle schema with their database name as the schema name, then set this field to database. If all subprograms owned by the same SQL Server user are defined in the same Oracle schema, then set this field to owner.

This field is empty by default. An Oracle server waits indefinitely for lock conflicts between transactions to be resolved. The value you enter for the LockTimeOut parameter is the number of seconds after which an Oracle server times out if it cannot obtain the requested locks. In the following example, the Oracle server times out after 60 seconds:. Connecting to an Oracle Data Source. As part of the connection process, an application can prompt you for information. If an application prompts you for information about an Oracle data source, do the following:.

An application must connect to a data source to access the data in it. Different applications connect to data sources at different times. For example, an application might connect to a data source only at your request, or it might connect automatically when it starts.

For information about when an application connects to a data source, see the documentation for that application. Data Source Configuration Options. Expired Password Behavior. If you try to connect to the database and your password has expired, you are prompted to change your password.

Upon making a successful password change, you are connected to the database. Instead, an error condition results, producing an error message and number that indicates that the password has expired. Implementation of Data Types Advanced. Limitations on Data Types.

In addition to Oracle's grammar, the vendor-specific escape sequences outlined in Appendix C of the ODBC specifications are also supported. Data Types for advanced users. Implementation of Data Types Programming. Floating Point Data Types. When connected to a Table describes these limitations.

The limiting factor is the client workstation memory. Oracle database allows only a single long data column per table. The driver derives this information both from errors detected by the driver and errors returned by the Oracle server. Native Error. Error Message. For errors that occur in the data source, the Oracle ODBC Driver returns an error message based on the message returned by the Oracle server. The prefixes in brackets [ ] identify the source of the error.

When the error occurs in the data source, the [vendor] and [ODBC-component] prefixes identify the vendor and name of the ODBC component that received the error from the data source. 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:.
