Functions

func New

func New() gdb.Driver

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

Types

type Driver

type Driver struct {
	*gdb.Core
}

func (*Driver) ConvertValueForField

func (d *Driver) ConvertValueForField(ctx context.Context, fieldType string, fieldValue interface{}) (interface{}, error)

ConvertValueForField converts value to the type of the record field.

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 forF 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 dm.

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 pgsql.

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.

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.
