This is a copy of pq's array functionality from github.com/lib/pq at 8446d16b8935fdf2b5c0fe333538ac395e3e1e4b.
It includes array.go, most of array_test.go, some of encode.go and errors.go, and LICENSE.md.
The code has been lightly modified to enable it to compile without the rest of the package.

Functions ¶
func Array ¶
Array returns the optimal driver.Valuer and sql.Scanner for an array or slice of any dimension.
For example:
db.Query(`SELECT * FROM t WHERE id = ANY($1)`, pq.Array([]int{235, 401}))
var x []sql.NullInt64
db.QueryRow(`SELECT ARRAY[235, 401]`).Scan(pq.Array(&x))
Scanning multi-dimensional arrays is not supported. Arrays where the lower bound is not one (such as `[0:0]={1}') are not supported.
func FormatTimestamp ¶
FormatTimestamp formats t into Postgres' text format for timestamps.
Types ¶
type ArrayDelimiter ¶
type ArrayDelimiter interface {
// ArrayDelimiter returns the delimiter character(s) for this element's type.
ArrayDelimiter() string
}
ArrayDelimiter may be optionally implemented by driver.Valuer or sql.Scanner to override the array delimiter used by GenericArray.
type BoolArray ¶
type BoolArray []bool
BoolArray represents a one-dimensional array of the PostgreSQL boolean type.
type ByteaArray ¶
type ByteaArray [][]byte
ByteaArray represents a one-dimensional array of the PostgreSQL bytea type.
func (*ByteaArray) Scan ¶
func (a *ByteaArray) Scan(src interface{}) error
Scan implements the sql.Scanner interface.
type Float32Array ¶
type Float32Array []float32
Float32Array represents a one-dimensional array of the PostgreSQL double precision type.
func (*Float32Array) Scan ¶
func (a *Float32Array) Scan(src interface{}) error
Scan implements the sql.Scanner interface.
type Float64Array ¶
type Float64Array []float64
Float64Array represents a one-dimensional array of the PostgreSQL double precision type.
func (*Float64Array) Scan ¶
func (a *Float64Array) Scan(src interface{}) error
Scan implements the sql.Scanner interface.
type GenericArray ¶
type GenericArray struct{ A interface{} }
GenericArray implements the driver.Valuer and sql.Scanner interfaces for an array or slice of any dimension.
func (GenericArray) Scan ¶
func (a GenericArray) Scan(src interface{}) error
Scan implements the sql.Scanner interface.
type Int32Array ¶
type Int32Array []int32
Int32Array represents a one-dimensional array of the PostgreSQL integer types.
func (*Int32Array) Scan ¶
func (a *Int32Array) Scan(src interface{}) error
Scan implements the sql.Scanner interface.
type Int64Array ¶
type Int64Array []int64
Int64Array represents a one-dimensional array of the PostgreSQL integer types.
func (*Int64Array) Scan ¶
func (a *Int64Array) Scan(src interface{}) error
Scan implements the sql.Scanner interface.
type StringArray ¶
type StringArray []string
StringArray represents a one-dimensional array of the PostgreSQL character types.
func (*StringArray) Scan ¶
func (a *StringArray) Scan(src interface{}) error
Scan implements the sql.Scanner interface.
