cursor

问题 I am using jQuery 1.6 and I have a text field for which I would like the cursor to be positioned at the end of the string\text after the field receives focus. Is there a trivial or easy to do this? At this time I am using the following code: $jQ('#css_id_value').focus(function(){ this.select(); }); $jQ('css_id_value').focus(); 回答1: $('#foo').focus(function() { if (this.setSelectionRange) { this.setSelectionRange(this.value.length, this.value.length); } else if (this.createTextRange) { // IE

问题 I have one group table with a recursive relation, so each record has a parent_id . Given a group, I need to get all the student (each belong to a group) names in all its subgroups, but ordered by student name. Do you know if there is any "easy" way to do it? If I have to do multiple queries, then I should order the results of the different Cursors, but Cursor has no orderBy(). Any ideas? Thank you so much! 回答1: As SQLite does not support recursive queries I implemented the select with two

问题 i wrote a python program like this that should run in multithreading mode: def Func(host,cursor,db): cursor.execute('''SELECT If_index, Username, Version, Community, Ip_traff FROM HOST WHERE Hostname = ?''',(host,)) #do something #--- Main --- db = sqlite3.connect(os.getcwd()+'\HOST', check_same_thread = False) #opendatabase cursor = db.cursor() #generate a cursor for ii in range(len(host)): #host is a list of ipaddress #for each host i want generate a thread thr = threading.Thread(target =

问题 I am looking to return a table of results from an Oracle function. Using a cursor would be easiest, but the application I have to work this into will not accept a cursor as a return value. The alternative is to create a type (likely wrapped in a package) to go along with this function. However, it seems somewhat superfluous to create several types (I have 4+ functions to write) just so I can return table results. Is there an alternative that I am missing? 回答1: UPDATE: See the first comment

问题 I'm using both ndb and search-api queries in my python appengine project. The only official docs on cursors I can find: https://cloud.google.com/appengine/docs/python/datastore/query-cursors https://cloud.google.com/appengine/docs/python/search/cursorclass Following things are unclear for me: What is cursor time-to-live ? Can I expose year-old cursors ? How would cursor pagination behave in case items are added/removed from original collection? (+ if cursor points to particular record, what

问题 I'm new to cursors and I'm trying to practice by building a dynamic python sql insert statement using a sanitized method for sqlite3: import sqlite3 conn = sqlite3.connect("db.sqlite") cursor = conn.cursor() list = ['column1', 'column2', 'column3', 'value1', 'value2', 'value3'] cursor.execute("""insert into table_name (?,?,?) values (?,?,?)""", list) When I attempt to use this, I get a syntax error "sqlite3.OperationalError: near "?"" on the line with the values. This is despite the fact that

问题 Need help in passing dynamic variable (table name) in cursor in Oracle stored procedure. My stored procedure: CREATE OR REPLACE PROCEDURE ABCDEF (TBL_NAME IN VARCHAR) IS CURSOR CUR IS SELECT * FROM TABLEA BEGIN FOR rec IN CUR LOOP . . . END I NEED THIS TABLEA in cursor to be replaced by TBL_NAME variable. I tried to make the cursor statement as executable statement but it didn't help me. Suggestions, please 回答1: Made this working using part of the solution above. Thanks for the suggestions.
