Potentially, these values are returned from calls to SQLDescribeCol, SQLColAttribute, SQLColumns, and SQLProcedureColumns. For example, assume procedure Example2 is defined to have four parameters. Also refer to this link: ORA-12170: TNS:Connect timeout occurred tips. From the start menu, select Programs, Administrative Tools, Data Sources(ODBC). Oracle Database limits literals in SQL statements to 4000 bytes.

String arguments are converted from Unicode to the local code page. DRV_GetRows: pICommand->Execute:rc=-2147217871):Extended = Timeout expired ORA-06512: at line 102 I have tried setting 'Connection Timeout', 'General Timeout' and 'Command Timeout' in the connection string in the UDL file to large numbers but none seem to make any difference. setting 60 means the timeout of 1 minute. Enable Closing Cursors - Enables closing cursors. For programmers, the noteworthy part of the implementation of the data types concerns the CHAR, VARCHAR, and VARCHAR2 data types. Use OCIDescribeAny - Check this box to gain a performance improvement by forcing the driver to use OCIDescribeAny()when an application makes heavy calls to small packaged procedures that return REF CURSORS. The Oracle server waits indefinitely for lock conflicts between transactions to be resolved. The behavior of ODBC driver can be changed by setting a value for the SQL_ATTR_ODBC_VERSION attribute by calling the SQLSetEnvAttr function. The SQLGetData function allows an ODBC application to specify the data type to receive a column as after the data has been fetched. For errors that occur in the data source, Oracle ODBC Driver maps the returned native error to the appropriate SQLSTATE. Native PL/SQL is not supported through ODBC. F implies that close cursor is to be disabled. The ODBC interface defines the following: A library of ODBC function calls that allows an application to connect to a data source, execute structured query language (SQL) statements, and retrieve results. In the ODBC Data Source Administrator dialog box, select the data source you want to delete from the Data Sources list. Changed the mapping of the Oracle data types, BINARY_FLOAT and BINARY_DOUBLE, to map to the ODBC data types, SQL_REAL and SQL_DOUBLE, respectively. This behavior is transparent to the userвЂ™s application, requiring no change to the ODBC application. F implies that thread safety is to be disabled. When you link your program, you must link it with the Driver Manager library, libodbc.so. Do not use this option when there are actual TIMESTAMP columns present or when data loss may occur. The default cache buffer size is 20 that are used only if statement caching option is enabled. See the Microsoft ODBC 3.52 Software Development Kit and Programmer's Reference for more information about the SQLDriverConnect function. When I try the same test setting with an MS_SQL Sever instead of an Oracle connection (via the Microsoft's driver manager for SQL Server as expected), everyting works fine and the timeout occurs. I have created an ODBC connection for oracle using 'Microsoft ODBC for Oracle' driver under user DSN. Already a Member? If the value of prefetch size is greater than 65536, the data fetched is only 65536 bytes. To do this, set the SQL_ATTR_QUERY_TIMEOUT attribute of the ODBC SQLSetStmtAttr function while calling this function before connecting to the data source. Then, use the ODBC Data Source Administrator to create a Data Source Name (DSN) for your connection. You can change or delete a data source at any time. Oracle ODBC driver supports implicit results with stored procedures or an anonymous PL/SQL block. For example, if the data were encoded in the database as ANSI, there would be an ANSI to Unicode conversion to fetch the data into Oracle ODBC Driver. The failure events map directly to the events defined in the OCI programming interface. The ODBC API supports both Unicode and ANSI entry points using the W and A suffix convention. The Oracle ODBC Driver Configuration Dialog Box is displayed. Bind NUMBER as FLOAT - Check this box to force the Oracle ODBC Driver to bind NUMBER column containing FLOAT data as Float instead of as the Binary Float (the default).
