iodbctest ["DSN=xxxx[;UID=xxxx][;PWD=xxxx][;OPT=value]"]
iodbctestw ["DSN=xxxx[;UID=xxxx][;PWD=xxxx][;OPT=value]"]

The iodbctest program and iodbtestw programs are simple ODBC sample programs, showing the strength of the ODBC API to connect to any ODBC enabled database, issue SQL commands and retrieve the query results.

The iodbctest program uses the standard ODBC API calls to connect using any DSN, but retrieves all results in ASCII mode.

The iodbctestw program uses the ODBC Unicode API calls to connect using any DSN, and retrieves all results in Unicode mode.

The iodbctest program uses the SQLDriverConnect function to make a connection using any available ODBC compliant driver. This allows the user to override any ODBC connect attribute in the DSN string.

Connect strings should start with either a DSN=xxx or a DRIVER=xxxx attribute optionally followed by other DSN attributes separated by a semicolon e.g:

	DSN=ora9;UID=scott;PWD=tiger;DATABASE=ora9u

Any attributes required for a proper connection that are not entered in the DSN connect string, must be present in the odbc.ini file.

If the connect string is passed as an argument to the iodbctest program, the string should be quoted as most shells use the semicolon as their command separator. If the connect string is entered on the interactive prompt, no quotes should be used.

After a successful connection has been established, the user is prompted for a SQL command to be send to the database. A SQL command cannot span multiple lines.

If the SQL command returns one or more result sets, each result set is fetched using character buffers and displayed in a table.

Additionally, the iodbctest program understands a few special commands:

qualifiers

Show a list of qualifiers using the SQLTables catalog call.

owners

Show a list of owners using the SQLTables catalog call.

tables

Show a list of tables using the SQLTables catalog call.

types

Show a list of tables types using the SQLTables catalog call.

datatypes

Show a list of data types using the SQLGetTypeInfo catalog call.

reconnect

Perform a disconnect/reconnect with the information saved during the first SQLDriverConnect.

quit (or exit)

Exit the program and return to the shell.

Start the iodbctest program and get a list of DSNs before making a connection:

    $ iodbctest
    OpenLink ODBC Demonstration program
    This program shows an interactive SQL processor

    Enter ODBC connect string (? shows list): ?

    SQL>

Connect to an Oracle 9 instance which has been previously setup in the odbc.ini file:

    $ iodbctest "DSN=ora9;UID=scott;PWD=tiger"
    iODBC Demonstration program
    This program shows an interactive SQL processor
    Driver: 05.20.0316 OpenLink Generic ODBC Driver (oplodbc.so)

    SQL>select * from emp

    ID               |NAME
    -----------------+-------------------------------------------
    1                |Record 1
    2                |Record 2
    2                |Record 3

     result set 1 returned 3 rows.

    SQL> quit
