Access, analyze, and report on data with your SQL-based tool of choice. Since Tableau closes a transaction after every read-only analytical query, streaming cursors may become truncated and lead to incomplete results displayed in Tableau. When autocommit is on, each statement is a separate transaction and is automatically committed when it completes successfully. For example, a site running multiple version 6. ODBC applications getting either of these errors when attempting to use server cursors with multiple statement batches or stored procedures should switch to using the ODBC default cursor options.

Unfortunately when I tried to use it on windows compiling my usual mingw64 waywhile it compiled and installed, it crashed when I attempted to connect to my SQL Server R2 box table, so I gave up on it for the inlime being as a cross-platform solution. The bulleted literals are specified as the fOption parameter, the literals grouped under each bulleted fOption are specified as vParam. For example, when an application attempts to open a named-pipe connection to a server that is currently shut down, the error string returned is:.

Keyset-driven cursors are controlled through a set of unique identifiers keysknown as the keyset. Is this page helpful? Many of the concepts apply to database applications in general. This parameter specifies whether the data source should log performance statistics.

The saved data source file contains examples of both types of customizations. Server cursors do oxbc support any SQL statements that generate multiple result sets, therefore they cannot be used when the application executes either a stored procedure or a batch containing more than one select. Tableau permits two types of customizations: There is another factor to consider in relation to how many stored procedures exist in tempdb.

This keyword specifies the workstation name to be recorded in the hostname column in master. All ODBC functions have return codes. Name the file odbc-sqlite.

Attempts to fetch the old key value generate the S error, but the new key value is not visible to the cursor. With this option set on, SQL statements should comply with the ANSI rule inlibe character data strings be enclosed in single quotes and that only identifiers, such as table or column names, be enclosed in double quotes:.

This will reduce the number of network roundtrips the application uses to perform the same work. The version distributed with SP2 has a few extra connection options related to controlling the ANSI options used by the driver. Please ensure that your browser supports and accepts cookies, or your comment cannot be verified correctly.

If the application uses a data source that has the performance-statistics profiling option activated, the driver writes the statistics header information to the log file and starts accumulating the statistics in its internal data structure when the application makes its first connection using the driver.

ODBC applications getting either of these errors when attempting to use server cursors with orbc statement batches or stored procedures should switch to using the ODBC default cursor options.

Since the SET options can be turned on and off at any time by users and applications, developers of stored procedures and triggers should also take care to test their procedures and triggers with the SET options listed above turned both on and off. In addition to the cursor types, cursor operations are also affected by the concurrency options set by the application:.

Like the ANSI options noted above, the version 2.

Applications should keep transactions as short as possible by not requiring user input while in a transaction. Review the lists to see the customizations you can use to tune your ODBC connection. The Connection properties describe the various options that can be used to establish a connection. This makes it impossible for the ODBC-related stored procedures to build up as a result of broken network connections or client computer inlnie.

Customize and Tune ODBC Connections

One thing I will say about it is that it accepts ad-hoc queries from what I can see, as a data source, which is pretty nice. The job of the Net-Library is to process TDS packets from the driver while insulating the driver from details of the rds protocol stack.

The driver sends a remote stored procedure call to have the server run the ODBC nnnnnnnn procedure. In other words, the data values and membership of rows in the cursor can change dynamically on each FETCH.

If an application executes the same statement many times, then the overhead of having the engine compile the plan every time degrades performance. See the CData KB to connect from many other applications. There is no indication of the return code for each function call.

Most other spreadsheet products also support opening a tab-delimited text file. Applications can request that the driver write all queries whose response exceeds a specified time limit to a file for later analysis by the programmer and dobc administrator.
