SQLite Module Function Reference
sqlite_open
sqlite_get_table
Synopsis
Get a table of results from a SQLite query
Usage
String_Type[] sqlite_get_table(Sqlite_Type db, String_Type query)
Description
This executes a query and returns the result as a 2d array of strings.
The first row of the array contains the column headers. This function does
not support placeholders.
Notes
You should only use this function if you need the column headers.
Otherwise, use
sqlite_get_table

sqlite_get_row
Synopsis
Get a row of results from a SQLite query
Usage
sqlite_get_row(Sqlite_Type db, String_Type query, ...)
Description
This executes a query and pushes the elements of the first row of the
result on the stack. This supports string, integer, float and blob
datatatypes. Blobs are returned as bstrings. If there are no rows, a
SqliteError exception is thrown even if the query executed flawlessly.
Question marks in the query are placeholders. Extra arguments to the
function are bound to these placeholders from left to right.
Example
(foo, bar) = sqlite_get_row("SELECT foo, bar FROM table WHERE baz = ?", "quux");
Notes
To get the result of a query that returns multiple rows, use
sqlite_get_array or use
foreach foo, bar (db) using ("SELECT foo, bar FROM table WHERE baz = ?", "quux")
{
....
}

Description
Executes a query and returns the result as a 2d array of type
type.
This supports string, integer, float and blob datatatypes. Question marks
in the query are placeholders. Extra arguments to the function are bound
to these placeholders from left to right.

sqlite_exec
Synopsis
Execute a SQLite query
Usage
sqlite_exec(Sqlite_Type db, String_Type query, ...)
Description
Execute a SQL query on a sqlite database, without returning a result.
Question marks in the query are placeholders. Extra arguments to the
function are bound to these placeholders from left to right.
Example
sqlite_exec("INSERT INTO table(foo,bar,baz) VALUES (?,?,?)", 1, 2, 3);

sqlite_changes
Synopsis
Get the number of rows affected by a SQLite query
Usage
Int_Type sqlite_changes(Sqlite_Type db)
Description
This function returns the number of database rows that were changed (or
inserted or deleted) by the most recently completed INSERT, UPDATE, or
DELETE statement. The change count for "DELETE FROM table" will be zero
regardless of the number of elements that were originally in the table.
