DESCRIPTION

The DeleteQuery class is used for the construction of SQL Delete queries that can then be executed on a target database.

Constructor & Destructor Documentation

DeleteQuery::__construct (   $tablename,
  $parameters = null,
  $limits = false 
)

Constructor. See affiliated setter functions for expanded descriptions as to the kinds of input that these arguments expect.

Parameters
$tablenameString the table to execute the delete on
$parametersarray|null Parameters that should be used to determine which rows are to be deleted
$limitsboolean Whether or not limits should be applied to the query

Member Function Documentation

DeleteQuery::makeQuery ( $query_string,
$dtype_string 
)

Sets the fields in the table that are to be updated.

This function expects an array of arrays: each array contaning two values. The first value is the name of the field. The second value is the appropriate dtype that the query expects as input for this field: Query::$DTYPE_D, Query::$DTYPE_I, or Query::$DTYPE_S.

Parameters
$updatefieldsarray The fields to be updated.
