jdbc - What is sql Type -10 (relating it Sql Server's nvarchar(max)) -

i've been investigating issues with jtds' mis-reporting of sql server's varchar(max) , nvarchar(max) column types (which recommended replacement of text , ntext).

between inet, jtds, ms jdbc database drivers, consistent column definition found using

rs = connection.getmetadata().getcolumns(null,null,tablename,columnname); rs.next(); rs.getint("sql_data_type");

(see link above source etc)

where sql_data_type "unused"

for varchar(max) drivers homecoming -1 => longvarchar. however, nvarchar(max) homecoming -10. type this, , how standard?

ah, see; java sql type constants derive sql standard somewhere. [the msdn page shows -10 sqldmo_dtypentext (as opposed -1ssqldmo_dtypetext)][1]. can't find page oracle, presumably because it's invested in java , sojava.sql.types` reference them.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
