Creates a prepared statement with the database that can then be used to execute multiple statements against. Within the closure, you would build the query in any normal way, though the Query Builder is the expected manner.


    public
                    prepare(callable(BaseConnection): mixed $func[, array<string|int, mixed> $options = [] ]) : BasePreparedQuery|null

Example: $stmt = $db->prepare(function($db) { return $db->table('users') ->where('id', 1) ->get(); })

Parameters

$func : callable(BaseConnection): mixed
$options : array<string|int, mixed> = []

Return values

BasePreparedQuery|null

pretend()

Allows the engine to be set into a mode where queries are not actually executed, but they are still generated, timed, etc.


    public
                    pretend([bool $pretend = true ]) : $this

This is primarily used by the prepared query functionality.

Parameters

$pretend : bool = true

Return values

$this

protectIdentifiers()

Protect Identifiers


    public
                    protectIdentifiers(array<string|int, mixed>|int|string $item[, bool $prefixSingle = false ][, bool $protectIdentifiers = null ][, bool $fieldExists = true ]) : array<string|int, mixed>|string

This function is used extensively by the Query Builder class, and by a couple functions in this class. It takes a column or table name (optionally with an alias) and inserts the table prefix onto it. Some logic is necessary in order to deal with column names that include the path. Consider a query like this:

SELECT hostname.database.table.column AS c FROM hostname.database.table

Or a query with aliasing:

SELECT m.member_id, m.member_name FROM members AS m

Since the column name can include up to four segments (host, DB, table, column) or also have an alias prefix, we need to do a bit of work to figure this out and insert the table prefix (if it exists) in the proper position, and escape only the correct identifiers.

Parameters

$item : array<string|int, mixed>|int|string
$prefixSingle : bool = false: Prefix a table name with no segments?
$protectIdentifiers : bool = null: Protect table or column names?
$fieldExists : bool = true: Supplied $item contains a column name?

Return values

array<string|int, mixed>|string

query()

Orchestrates a query against the database. Queries must use Database\Statement objects to store the query and build it.


    public
                    query(string $sql[, array<string|int, mixed>|string|null $binds = null ][, bool $setEscapeFlags = true ][, string $queryClass = '' ]) : BaseResult|bool|Query

This method works with the cache.

Should automatically handle different connections for read/write queries if needed.

Parameters

$sql : string
$binds : array<string|int, mixed>|string|null = null
$setEscapeFlags : bool = true
$queryClass : string = ''

Return values

BaseResult|bool|Query —

BaseResult when “read” type query, bool when “write” type query, Query when prepared query
