The data values provided with the API can also be accessed by SQL special register. The values in these registers are stored in the database code page. Data values provided with this API are converted to the database code page before being stored in the special registers. Any data value that exceeds the maximum supported size after conversion to the database code page will be truncated before being stored at the server. These truncated values will be returned by the special registers. The original data values will also be stored at the server and are not converted to the database code page. The unconverted values can be returned by calling the sqleqryi API.
