prepare()

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.

Example: $stmt = $db->prepare(function($db)

   {
     return $db->table('users')
           ->where('id', 1)
             ->get();

pretend()

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

This is primarily used by the prepared query functionality.

Parameter Name	Type	Description
$pretend	bool

Returns: $this

protectIdentifiers()

Protect Identifiers

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.

Parameter Name	Type	Description
$item	string|array
$prefixSingle	bool
$protectIdentifiers	bool
$fieldExists	bool

Returns: string|array

query()

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

This method works with the cache.

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

Parameter Name	Type	Description
$sql	string
...$binds	mixed
$setEscapeFlags	bool
$queryClass	string
$binds

Returns: \CodeIgniter\Database\BaseResult|\CodeIgniter\Database\Query|bool

reconnect()

Keep or establish the connection if no queries have been sent for a length of time exceeding the server's idle timeout.

Returns: bool

resetDataCache()

Empties our data cache. Especially helpful during testing.

Returns: $this

setAliasedTables()

Sets the Table Aliases to use. These are typically collected during use of the Builder, and set here so queries are built correctly.

Parameter Name	Type	Description
$aliases	array

Returns: $this

setDatabase()

Select a specific database table to use.

Parameter Name	Type	Description
$databaseName	string

Returns: mixed

setPrefix()

Set DB Prefix

Set's the DB Prefix to something new without needing to reconnect

Parameter Name	Type	Description
$prefix	string	The

Returns: string

shouldReturn()

Parameter Name	Type	Description
$method
$return

Returns: void

showLastQuery()

Returns a string representation of the last query's statement object.

Returns: string

simpleQuery()

Performs a basic query against the database. No binding or caching is performed, nor are transactions handled. Simply takes a raw query string and returns the database-specific result id.

Parameter Name	Type	Description
$sql	string

Returns: mixed

table()

Returns an instance of the query builder for this connection.

Parameter Name	Type	Description
$tableName	string|array

Returns: \BaseBuilder

tableExists()

Determine if a particular table exists

Parameter Name	Type	Description
$tableName	string

Returns: bool

Begin Transaction

Parameter Name	Type	Description
$test_mode	bool

Returns: bool

transCommit()

Commit Transaction

Returns: bool

transComplete()

Complete Transaction

Returns: bool

transOff()

Disable Transactions

Returns: bool

transStart()

Parameter Name	Type	Description
$test_mode	bool	=

Returns: bool

transStatus()

Lets you retrieve the transaction flag to determine if it has failed

Returns: bool

transStrict()

Enable/disable Transaction Strict Mode

When strict mode is enabled, if you are running multiple groups of transactions, if one group fails all subsequent groups will be rolled back.

If strict mode is disabled, each group is treated autonomously, meaning a failure of one group will not affect any others

Parameter Name	Type	Description
$mode	bool	=

Returns: $this
