java - Default detail formatter for arrays in Eclipse -

when debugging java programme in eclipse, in variables view, when highlight variable prints detail variable in pane below. pane called "detail view," , value displayed "detail" variable. default, result of calling .tostring() on variable. eclipse allows specify , customize "detail formatters" arbitrary objects maps them more helpful , descriptive strings in view.

my question this: .tostring() method invoked on array (say of integers) returns unhelpful memory address. however, when highlight array variable in debug mode, eclipse seems intelligently parse helpful comma-delimited string (e.g. "[42, 13, null, 19]"). gather means eclipse has established default detail formatter arrays helpful functionality. does know how can leverage detail formatter in code avoid rewriting identical logic?

in case you're interested, motivation generating contents of in clause sql query. is, i'm trying generate sql query:

select * table id in (1,2,3)

from on arbitrary int[]:

int[] ids = new int[] {1,2,3}

i realize accomplish writing loop, using stringbuilder, etc., wondering if eclipse has done me , exposes helpful method (read: exceedingly lazy)

eclipse uses arrays.tostring, if want utilize parentheses instead of square brackets, might want utilize guava:

return "(" + ints.join(",", array) + ")";

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...
