According to this page in the online manual http://www.mysql.com/doc/en/C_API_Prepared_statement_datatypes.html, the length element of the MYSQL_BIND structure when set to 0 will treat the buffer element as a NULL terminated string.
If I do such a thing, prepare some query, bind some columns and execute it, the string values inserted into the database are not correct. What it looks like it is doing is when length is 0, it uses buffer_length instead of doing a strlen( buffer ). To see this, try inserting some data with setting length, run a query like SELECT CONCAT( 'x', <col>, 'x' ) FROM <table>; You get back values like xVALUEx Now try inserting some data leaving length set to 0 and rerun the same query as above and you get: xVALUE The trailing x never gets displayed So my question is, is this a bug in the API, a bug in the documentation, or just an unfinished feature? -- Nathaniel Blanchard Developer Sane Solutions, LLC 401-295-4809 ext 142 401-295-4154 fax [EMAIL PROTECTED] This e-mail message may contain confidential information.
