muliOption | One of the LRD Binding Options.

## Example

In the following example, lrd_assign assigns values to the host variable F_D1 and L_D2. The lr_bind_placeholder function binds the host variable to the placeholders F and L.

     /* Insert employee data into the employee table. */

    // For Oracle
    lrd_stmt(Csr2, "insert into employees (emp_firstname,emp_lastname)", "values(:F,:L)", -1, 1 /*Deferred*/, 1 /*Dflt Ora Ver*/, 0);

    /* For OCBC values in lrd_stmt are represented with "?": "values(?,?)" */
    lrd_assign(&F_D1, "Jim", "", 0, 0);
    lrd_assign(&F_D1, "Bob", "", 1, 0);
    lrd_assign(&F_D1, "Mike", "", 2, 0);

    // For Oracle
    lrd_bind_placeholder(Csr2, "F", &F_D1, 0, 0);

    /* For ODBC, use column number as place holder instead of "F":
        lrd_bind_placeholder(Csr2, "1", &F_D1, 0, 0); */

    lrd_assign(&L_D2, "Smith", "", 0, 0);
    lrd_assign(&L_D2, "Jones", "", 1, 0);
    lrd_assign(&L_D2, "Anderson", "", 2, 0);

    // For Oracle

    lrd_bind_placeholder(Csr2, "L", &L_D2, 0, 0);

    /* For ODBC, use column number as place holder instead of "L":
        lrd_bind_placeholder(Csr2, "2", &L_D2, 0, 0);  */
