# SQLite Functions

## Predefined Classes

## SQLiteDatabase

Represents an opened SQLite database.

## Constructor

- __construct - construct a new SQLiteDatabase object

## Methods

- query - Execute a query
- queryExec - Execute a result-less query
- arrayQuery - Execute a query and return the result as an array
- singleQuery - Execute a query and return either an array for one single column or the value of the first row
- unbufferedQuery - Execute an unbuffered query
- lastInsertRowid - Returns the rowid of the most recently inserted row
- changes - Returns the number of rows changed by the most recent statement
- createAggregate - Register an aggregating UDF for use in SQL statements
- createFunction - Register a UDF for use in SQL statements
- busyTimeout - Sets or disables busy timeout duration
- lastError - Returns the last error code of the most recently encountered error
- fetchColumnTypes - Return an array of column types from a particular table

## SQLiteResult

Represents a buffered SQLite result set.

## Methods

- fetch - Fetches the next row from the result set as an array
- fetchObject - Fetches the next row from the result set as an object
- fetchSingle - Fetches the first column from the result set as a string
- fetchAll - Fetches all rows from the result set as an array of arrays
- column - Fetches a column from the current row of the result set
- numFields - Returns the number of fields in the result set
- fieldName - Returns the name of a particular field in the result set
- current - Fetches the current row from the result set as an array
- key - Return the current row index
- next - Seek to the next row number
- valid - Returns whether more rows are available
- rewind - Seek to the first row number of the result set
- prev - Seek to the previous row number of the result set
- hasPrev - Returns whether or not a previous row is available
- numRows - Returns the number of rows in the result set
- seek - Seek to a particular row number

## SQLiteUnbuffered

Represents an unbuffered SQLite result set. Unbuffered results sets are sequential, forward-seeking only.

## Methods

- fetch - Fetches the next row from the result set as an array
- fetchObject - Fetches the next row from the result set as an object
- fetchSingle - Fetches the first column from the result set as a string
- fetchAll - Fetches all rows from the result set as an array of arrays
- column - Fetches a column from the current row of the result set
- numFields - Returns the number of fields in the result set
- fieldName - Returns the name of a particular field in the result set
- current - Fetches the current row from the result set as an array
- next - Seek to the next row number
- valid - Returns whether more rows are available
