Methods summary
`public boolean`	# `check( )` Abstract method for checking database driver base functions. If this check fails, the database connection will not be established. Abstract method for checking database driver base functions. If this check fails, the database connection will not be established. Returns `boolean` See `cDbDriverAbstract::check()`
`public object\|resource\|integer\|null`	# `connect( )` Connects to the database. Connects to the database. Returns `object\|resource\|integer\|null` value depends on used driver and is NULL in case of an error. See `cDbDriverAbstract::connect()`
`public string`	# `buildInsert( string $tableName, array $fields )` Builds a insert query. String values in passed fields parameter will be escaped automatically. Builds a insert query. String values in passed fields parameter will be escaped automatically. Parameters `$tableName` `string` $tableName The table name `$fields` `array` $fields Associative array of fields to insert Returns `string` The INSERT SQL query See `cDbDriverAbstract::buildInsert()`
`public string`	# `buildUpdate( string $tableName, array $fields, array $whereClauses )` Builds a update query. String values in passed fields and whereClauses parameter will be escaped automatically. Builds a update query. String values in passed fields and whereClauses parameter will be escaped automatically. Parameters `$tableName` `string` $tableName The table name `$fields` `array` $fields Assoziative array of fields to update `$whereClauses` `array` $whereClauses Assoziative array of field in where clause. Multiple entries will be concatenated with AND. Returns `string` The UPDATE query See `cDbDriverAbstract::buildUpdate()`
`public`	# `query( string $query )` Executes the query. Executes the query. Parameters `$query` `string` $statement The query to execute See `cDbDriverAbstract::query()`
`public integer`	# `nextRecord( )` Moves the result to the next record, if exists and returns the status of the movement Moves the result to the next record, if exists and returns the status of the movement Returns `integer` Flag about move status 1 on success or 0 See `cDbDriverAbstract::nextRecord()`
`public Ambigous`	# `getResultObject( string $className = NULL )` This method returns the current result set as object or NULL if no result set is left. If optional param $className is set, the result object is an instance of class $className. This method returns the current result set as object or NULL if no result set is left. If optional param $className is set, the result object is an instance of class $className. Parameters `$className` `string` $className [optional] Returns `Ambigous` <NULL, object, false> See `cDbDriverAbstract::getResultObject()`
`public integer`	# `affectedRows( )` Returns number of affected rows from last executed query (update, delete) Returns number of affected rows from last executed query (update, delete) Returns `integer` Number of affected rows See `cDbDriverAbstract::affectedRows()`
`public integer`	# `numRows( )` Returns the number of rows from last executed select query. Returns the number of rows from last executed select query. Returns `integer` The number of rows from last select query result See `cDbDriverAbstract::numRows()`
`public integer`	# `numFields( )` Returns the number of fields (columns) from current record set Returns the number of fields (columns) from current record set Returns `integer` Number of fields See `cDbDriverAbstract::numFields()`
`public \|cDbDriverMysqli`	# `free( )` Discard the query result Discard the query result Returns `\|cDbDriverMysqli` If aggregated handler has no query id, this object is returned, otherwise void. See `cDbDriverAbstract::free()` Todo check if $this should be returned
`public string`	# `escape( string $string )` Escape string for using in SQL-Statement. Escape string for using in SQL-Statement. Parameters `$string` `string` $string The string to escape Returns `string` Escaped string See `cDbDriverAbstract::escape()`
`public integer`	# `seek( integer $pos = 0 )` Moves the cursor (position inside current result sets). Moves the cursor (position inside current result sets). Parameters `$pos` `integer` $pos [optional] The positon to move to inside the current result set Returns `integer` See `cDbDriverAbstract::seek()`
`public array`	# `getMetaData( string $tableName, boolean $full = false )` Parses the table structure and generates metadata from it. Parses the table structure and generates metadata from it. Due to compatibility problems with table we changed the behavior of metadata(). Depending on $full, metadata returns the following values: full is false (default): $result[]: [0]["table"] table name [0]["name"] field name [0]["type"] field type [0]["len"] field length [0]["flags"] field flags full is true $result[]: ["num_fields"] number of metadata records [0]["table"] table name [0]["name"] field name [0]["type"] field type [0]["len"] field length [0]["flags"] field flags ["meta"][field name] index of field named "field name" This last one could be used if you have a field name, but no index. Test: if (isset($result['meta']['myfield'])) { ... Parameters `$tableName` `string` $tableName The table to get metadata or empty string to retrieve metadata of all tables. `$full` `boolean` $full [optional] Flag to load full metadata. Returns `array` Depends on used database and on parameter $full See `cDbDriverAbstract::getMetaData()`
`public array`	# `getTableNames( )` Fetches all table names. Fetches all table names. Returns `array` See `cDbDriverAbstract::getTableNames()`
`public array`	# `getServerInfo( )` Fetches server information. Fetches server information. Returns `array` See `cDbDriverAbstract::getServerInfo()`
`public integer`	# `getErrorNumber( )` Returns error code of last occured error by using databases interface. Returns error code of last occured error by using databases interface. Returns `integer` See `cDbDriverAbstract::getErrorNumber()`
`public string`	# `getErrorMessage( )` Returns error message of last occured error by using databases interface. Returns error message of last occured error by using databases interface. Returns `string` See `cDbDriverAbstract::getErrorMessage()`
`public`	# `disconnect( )` Closes the connection and frees the query id. Closes the connection and frees the query id. See `cDbDriverAbstract::disconnect()`
