Overview

Package oracle implements gdb.Driver, which supports operations for database Oracle.

Note: 1. It does not support Save/Replace features. 2. It does not support LastInsertId.

Functions

func New

func New() gdb.Driver

New create and returns a driver that implements gdb.Driver, which supports operations for Oracle.

Types

type Driver

type Driver struct {
	*gdb.Core
}

Driver is the driver for oracle database.

func (*Driver) DoFilter

func (d *Driver) DoFilter(ctx context.Context, link gdb.Link, sql string, args []interface{}) (newSql string, newArgs []interface{}, err error)

DoFilter deals with the sql string before commits it to underlying sql driver.

func (*Driver) DoInsert

func (d *Driver) DoInsert(
	ctx context.Context, link gdb.Link, table string, list gdb.List, option gdb.DoInsertOption,
) (result sql.Result, err error)

DoInsert inserts or updates data for given table.

func (*Driver) GetChars

func (d *Driver) GetChars() (charLeft string, charRight string)

GetChars returns the security char for this type of database.

func (*Driver) New

func (d *Driver) New(core *gdb.Core, node *gdb.ConfigNode) (gdb.DB, error)

New creates and returns a database object for oracle. It implements the interface of gdb.Driver for extra database driver installation.

func (*Driver) Open

func (d *Driver) Open(config *gdb.ConfigNode) (db *sql.DB, err error)

Open creates and returns an underlying sql.DB object for oracle.

func (*Driver) OrderRandomFunction

func (d *Driver) OrderRandomFunction() string

OrderRandomFunction returns the SQL function for random ordering.

func (*Driver) TableFields

func (d *Driver) TableFields(ctx context.Context, table string, schema ...string) (fields map[string]*gdb.TableField, err error)

TableFields retrieves and returns the fields' information of specified table of current schema.

Also see DriverMysql.TableFields.

func (*Driver) Tables

func (d *Driver) Tables(ctx context.Context, schema ...string) (tables []string, err error)

Tables retrieves and returns the tables of current schema. It's mainly used in cli tool chain for automatically generating the models. Note that it ignores the parameter `schema` in oracle database, as it is not necessary.
