Web SQL Database
(So the first ? placeholder gets bound to the first value in the arguments array, and generally the nth ? placeholder gets bound to the nth value in the arguments array.) Binding the ? placeholders is done at the literal level, not as string concatenations, so this provides a way to dynamically insert parameters into a statement without risk of a SQL injection attack. Treating persistent storage as cookies If users attempt to protect their privacy by clearing cookies without also clearing data stored in the relevant databases, sites can defeat those attempts by using the two features as redundant backup for each other
Actually, this part of the code should be in the app Delegate and you should add some code to see if the database is already in the document folder.As for saving, I have noticed since upgrading the version of iOS my inserts are no longer working. Are you trying to enter data from an UI and store that information through a loop using a custom object? I am currently writing a tutorial, as someone else's request to display data from a NSArray and display that information in a UITableView
Choose one architecure and the warning sign will gone.Problem: The type or namespace name 'SQLite' could not be found (are you missing a using directive or an assembly reference?) Make sure you have two new files in your project after installing sqlite-net (SQLLite and SQLiteAsync). It was a permissions error with my new RTM machine!!BTW one more question, can I use the same sqlite3.dll and reference it from normal .net projects, or do I need to recompile it? If so please say you have it (x64) already compiled

Besides preventing SQL injection attacks, it may also improve performance by preparing a SQL statement once and executing it multiple times with different parameters. Otherwise, an exception will be triggered and caught, and the rollBack() method is called to roll back the changes made by the queries prior to that failed query in the transaction
I would like to keep updating this pre-loaded database with fields and thus needed a way to update the database without copying it over everytime the app loaded. I figured I would create the db from scratch and populate it with data from the strings.xml, when the application is first loaded, and the database is created the first time
sql - Another way to run reports on a SpiceWorks SQLite database using a linked server in SSMS? - Code Review Stack Exchange
getting rid of the second Query reduced the amount of queries to the SQLite database to just one, the other way was executing the second query an outrageous amount of times because the second query would run once for every row in the first query, THIS IS HORRIBLY INEFFICIENT, do not do this unless you absolutely have to. I still don't have a solid way of passing variables to the OPENQUERY, but that is a question perhaps for StackOverflow when I have more time to work on this project
Comparison of different SQL implementations
Instead, a MSSQL 2000-specific syntax was needed: SELECT TOP n columns FROM tablename ORDER BY key ASC The TOP construct is still available in MSSQL 2008, and it's handy for casual SQL work. Standard Optional feature T171 defines LIKE clause in table definition: CREATE TABLE t2 ( LIKE t1 ) The DBMS may support an extension of this (feature T173) which allows for more table properties to be copied: CREATE TABLE t2 ( LIKE t1 INCLUDING IDENTITY INCLUDING DEFAULTS INCLUDING GENERATED ) If INCLUDING DEFAULTS is not specified, column defaults will not be part of t2; likewise with IDENTITY and GENERATED properties
SQL to Select a random row from a database table
i need to retrieve the data of 1000 rows at once in the output and when i scroll down to the last row i.e 1000th row then again i need to retrieve another 1000 rows and add it to the output using stored procedures.if any one has any idea please post the query etc. The database struture same for all the clients.My question is how to select a table from all the databaseslike select * from mytable where mytable in ...
With DaDaBIK (differently from many similar softwares) you don't produce a PHP script, which would become outdated when you modify the schema of your database, but instead you directly use its abstraction layer that can be easily updated every time you modify your database's schema. At this level you can: Choose the database tables you want to include in your DaDaBIK application Configure your datagrids, choosing between a classic tabular data grid view (default) or a custom results page completely customizable using HTML templates

For example, the documentation link above shows how to derive the behavior of the .schema and .tables commands, using normal SQL commands (see section: Querying the database schema)
SQLite Frequently Asked Questions
Is this a bug? If the columns of your result set are named by AS clauses, then SQLite is guaranteed to use the identifier to the right of the AS keyword as the column name. It is true that Informix and Microsoft SQL Server use interpretation (2), however we the SQLite developers hold that interpretation (1) is the most natural reading of the requirement and we also want to maximize compatibility with other SQL database engines, and most other database engines also go with (1), so that is what SQLite does
SQLite Python tutorial
Columns in the result set include the column order number, column name, data type, whether or not the column can be NULL, and the default value for the column
Command Line Shell For SQLite
Compiling the sqlite3 program from sources The source code to the sqlite3 command line interface is in a single file named "shell.c" which you can download from the SQLite website. If you specify a column a width of 0, then the column width is automatically adjusted to be the maximum of three numbers: 10, the width of the header, and the width of the first row of data
SQLite Query Language: ALTER TABLE
If any views refer to table X in a way that is affected by the schema change, then drop those views using DROP VIEW and recreate them with whatever changes are necessary to accommodate the schema change using CREATE VIEW. If foreign key constraints are enabled when a table is renamed, then any REFERENCES clauses in any table (either the table being renamed or some other table) that refer to the table being renamed are modified to refer to the renamed table by its new name
