Functions

func GetLastInsertId

func GetLastInsertId(id int64) string

GetLastInsertId returns rowid from LastInsertId

func NewConnector

func NewConnector(hosts ...string) driver.Connector

func QueryEscape

func QueryEscape(s string) string

type DSN

type DSN struct {
	Connect  string
	Username string
	Password string
	// contains filtered or unexported fields
}

DSN is Oracle Data Source Name

func ParseDSN

func ParseDSN(dsnString string) (dsn *DSN, err error)

ParseDSN parses a DSN used to connect to Oracle

It expects to receive a string in the form:

[username/[password]@]host[:port][/service_name][?param1=value1&...&paramN=valueN]

Connection timeout can be set in the Oracle files: sqlnet.ora as SQLNET.OUTBOUND_CONNECT_TIMEOUT or tnsnames.ora as CONNECT_TIMEOUT

Supported parameters are:

loc - the time location for reading timestamp (without time zone). Defaults to UTC Note that writing a timestamp (without time zone) just truncates the time zone.

isolation - the isolation level that can be set to: READONLY, SERIALIZABLE, or DEFAULT

prefetch_rows - the number of top level rows to be prefetched. Defaults to 0. A 0 means unlimited rows.

prefetch_memory - the max memory for top level rows to be prefetched. Defaults to 4096. A 0 means unlimited memory.

questionph - when true, enables question mark placeholders. Defaults to false. (uses strconv.ParseBool to check for true)

type DriverStruct

type DriverStruct struct {
	// Logger is used to log connection ping errors, defaults to discard
	// To log set it to something like: log.New(os.Stderr, "oci8 ", log.Ldate|log.Ltime|log.LUTC|log.Lshortfile)
	Logger *log.Logger
}

DriverStruct is Oracle driver struct

func (*DriverStruct) Open

func (drv *DriverStruct) Open(dsnString string) (driver.Conn, error)

Open opens a new database connection

type EscapeError

type EscapeError string

EscapeError for invalid escape

func (EscapeError) Error

func (e EscapeError) Error() string

Error returns string for invalid URL escape

type Result

type Result struct {
	// contains filtered or unexported fields
}

Result is Oracle result

func (*Result) LastInsertId

func (result *Result) LastInsertId() (int64, error)

LastInsertId returns last inserted ID

func (*Result) RowsAffected

func (result *Result) RowsAffected() (int64, error)

func (rows *Rows) ColumnTypeDatabaseTypeName(i int) string

ColumnTypeDatabaseTypeName implement RowsColumnTypeDatabaseTypeName.

func (*Rows) ColumnTypeLength

func (rows *Rows) ColumnTypeLength(i int) (int64, bool)

ColumnTypeLength is returning OCI_ATTR_DATA_SIZE, which is max data size in bytes. Note this is not returing length of the column type, like the 20 in FLOAT(20), which is what is normally expected. TODO: Should / can it be changed to return length of the column type?

func (*Rows) ColumnTypeScanType

func (rows *Rows) ColumnTypeScanType(i int) reflect.Type

ColumnTypeScanType implement RowsColumnTypeScanType.

type Values

type Values map[string][]string

Values maps a string key to a list of values. It is typically used for query parameters and form values. Unlike in the http.Header map, the keys in a Values map are case-sensitive.

func ParseQuery

func ParseQuery(query string) (m Values, err error)

ParseQuery parses the URL-encoded query string and returns a map listing the values specified for each key. ParseQuery always returns a non-nil map containing all the valid query parameters found; err describes the first decoding error encountered, if any.

func (Values) Add

func (Values) Get

func (v Values) Get(key string) string

Get gets the first value associated with the given key. If there are no values associated with the key, Get returns the empty string. To access multiple values, use the map directly.

func (Values) Set

func (v Values) Set(key, value string)

Set sets the key to value. It replaces any existing values.
