Operating Systems Linux Red Hat Network becomes slow and return fast only after restart network Post 302895620 by rbatte1 on Tuesday 1st of April 2014 01:17:08 PM

There may be repeated rogue queries that are trying to return vast amounts of data. If the user is disconnected/timed out/gets bored, they may well re-issue. I would consider reading the application logs to check that the queries are indeed going to return suitable data volumes.

This was learned from prolonged painful experience eventually leading to better validation and sanity checking on the application server before the query was executed.

SQLITE_QUERY(3) 														   SQLITE_QUERY(3)

sqlite_query - Executes a query against a given database and returns a result handle

SYNOPSIS
resource sqlite_query (resource $dbhandle, string $query, [int $result_type = SQLITE_BOTH], [string &$error_msg]) DESCRIPTION
resource sqlite_query (string $query, resource $dbhandle, [int $result_type = SQLITE_BOTH], [string &$error_msg]) Object oriented style (method): SQLiteResult SQLiteDatabase::query (string $query, [int $result_type = SQLITE_BOTH], [string &$error_msg]) Executes an SQL statement given by the $query against a given database handle. PARAMETERS
o $dbhandle - The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the object-oriented method. o $query - The query to be executed. Data inside the query should be properly escaped. o $result_type -The optional $result_type parameter accepts a constant and determines how the returned array will be indexed. Using SQLITE_ASSOC will return only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers). SQLITE_BOTH will return both associative and numerical indices. SQLITE_BOTH is the default for this function. o $error_msg - The specified variable will be filled if an error occurs. This is specially important because SQL syntax errors can't be fetched using the sqlite_last_error(3) function. Note Two alternative syntaxes are supported for compatibility with other database extensions (such as MySQL). The preferred form is the first, where the $dbhandle parameter is the first parameter to the function. RETURN VALUES
This function will return a result handle or FALSE on failure. For queries that return rows, the result handle can then be used with func- tions such as sqlite_fetch_array(3) and sqlite_seek(3). Regardless of the query type, this function will return FALSE if the query failed. sqlite_query(3) returns a buffered, seekable result handle. This is useful for reasonably small queries where you need to be able to ran- domly access the rows. Buffered result handles will allocate memory to hold the entire result and will not return until it has been fetched. If you only need sequential access to the data, it is recommended that you use the much higher performance sqlite_unbuffered_query(3) instead. CHANGELOG
+--------+---------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------+ | 5.1.0 | | | | | | | Added the $error_msg parameter | | | | +--------+---------------------------------+ NOTES
Warning SQLite will execute multiple queries separated by semicolons, so you can use it to execute a batch of SQL that you have loaded from a file or have embedded in a script. However, this works only when the result of the function is not used - if it is used, only the first SQL statement would be executed. Function sqlite_exec(3) will always execute multiple SQL statements. When executing multiple queries, the return value of this function will be FALSE if there was an error, but undefined otherwise (it might be TRUE for success or it might return a result handle).
