Public Methods

Method	Description
createTableFromCSVFile ( string $tableName, array $fields, string $filePath, array $fileSpec ) : boolean	Batch insert into table from CSV (or other delimited) file.
tableInsertBatch ( string $tableName, array $fields, array $values, boolean $throwException = false, string $charset = 'utf8' ) : boolean	Performs a batch insert into a specific table using either LOAD DATA INFILE or plain INSERTs, as a fallback. On MySQL, LOAD DATA INFILE is 20x faster than a series of plain INSERTs.
tableInsertBatchIterate ( string $tableName, array $fields, array $values, boolean $ignoreWhenDuplicate = true )	Performs a batch insert into a specific table by iterating through the data

Protected Methods

Method Details

createCSVFile() protected static method

Create CSV (or other delimited) files

protected static createCSVFile ( string $filePath, array $fileSpec, array $rows )
$filePath	string	filename to create
$fileSpec	array	File specifications (delimiter, line terminator, etc)
$rows	array	Array of array corresponding to rows of values

createTableFromCSVFile() public static method

Batch insert into table from CSV (or other delimited) file.

public static createTableFromCSVFile ( string $tableName, array $fields, string $filePath, array $fileSpec ) : boolean
$tableName	string	Name of table
$fields	array	Field names
$filePath	string	Path name of a file.
$fileSpec	array	File specifications (delimiter, line terminator, etc)
return	boolean	True if successful; false otherwise

tableInsertBatch() public static method

Performs a batch insert into a specific table using either LOAD DATA INFILE or plain INSERTs, as a fallback. On MySQL, LOAD DATA INFILE is 20x faster than a series of plain INSERTs.

public static tableInsertBatch ( string $tableName, array $fields, array $values, boolean $throwException = false, string $charset = 'utf8' ) : boolean
$tableName	string	PREFIXED table name! you must call Common::prefixTable() before passing the table name
$fields	array	array of unquoted field names
$values	array	array of data to be inserted
$throwException	boolean	Whether to throw an exception that was caught while trying LOAD DATA INFILE, or not.
$charset	string	The charset to use, defaults to utf8
return	boolean	True if the bulk LOAD was used, false if we fallback to plain INSERTs

tableInsertBatchIterate() public static method

NOTE: you should use tableInsertBatch() which will fallback to this function if LOAD DATA INFILE not available

public static tableInsertBatchIterate ( string $tableName, array $fields, array $values, boolean $ignoreWhenDuplicate = true )
$tableName	string	PREFIXED table name! you must call Common::prefixTable() before passing the table name
$fields	array	array of unquoted field names
$values	array	array of data to be inserted
$ignoreWhenDuplicate	boolean	Ignore new rows that contain unique key values that duplicate old rows
