Functions ¶
func ParseTimestamp ¶
ParseTimestamp parses Postgres' text format. It returns a time.Time in currentLocation iff that time's offset agrees with the offset sent from the Postgres server. Otherwise, ParseTimestamp returns a time.Time with the fixed offset offset provided by the Postgres server.
Types ¶
type PgConn ¶
type PgConn struct {
// contains filtered or unexported fields
}
func NewPgConnContext ¶
func (PgConn) CheckNamedValue ¶
func (c PgConn) CheckNamedValue(nv *driver.NamedValue) error
CheckNamedValue NamedValueChecker可以可选地由Conn或Stmt实现。 它为驱动程序提供了更多控制来处理Go和数据库类型，超出了允许的默认值类型。
sql包按以下顺序检查值检查器，在第一个找到的匹配项处停止： Stmt.NamedValueChecker，Conn.NamedValueChecker，Stmt.ColumnConverter，DefaultParameterConverter。
如果CheckNamedValue返回ErrRemoveArgument，则NamedValue将不包含在最终查询参数中。 这可用于将特殊选项传递给查询本身。
如果返回ErrSkip，则会将列转换器错误检查路径用于参数。 司机可能希望在他们用完特殊情况后退回ErrSkip。
func (PgConn) ExecContext ¶
func (PgConn) PrepareContext ¶
type PgRows ¶
type PgRows struct {
// contains filtered or unexported fields
}
func (*PgRows) ColumnTypeDatabaseTypeName ¶
func (*PgRows) ColumnTypeLength ¶
func (*PgRows) ColumnTypePrecisionScale ¶
ColumnTypePrecisionScale may be implemented by Rows. It should return the precision and scale for decimal types. If not applicable, ok should be false.
func (*PgRows) HasNextResultSet ¶
HasNextResultSet is called at the end of the current result set and reports whether there is another result set after the current one.
func (*PgRows) NextResultSet ¶
NextResultSet advances the driver to the next result set even if there are remaining rows in the current result set.
NextResultSet should return io.EOF when there are no more result sets.
type PgStmt ¶
func NewPgStmtContext ¶
func (PgStmt) ExecContext ¶
ExecContext executes a query that doesn't return rows, such as an INSERT or UPDATE.
ExecContext must honor the context timeout and return when it is canceled.
func (PgStmt) QueryContext ¶
func (s PgStmt) QueryContext(ctx context.Context, args []driver.NamedValue) (_ driver.Rows, err error)
QueryContext executes a query that may return rows, such as a SELECT.
QueryContext must honor the context timeout and return when it is canceled.
