示例1: All
// All is for fetching all records
func (d *Driver) All(tablename string, fields []field.Field, ctx context.Context) ([][]field.Field, error) {
if tx := ctx.GetTx(); tx != nil {
return tx.(*Driver).All(tablename, fields, ctx.SetTx(nil))
}
return d.getTable(tablename), nil
}示例2: Where
// Where is for fetching specific records
func (d *Driver) Where(tablename string, fields []field.Field, ctx context.Context, where string, args ...interface{}) ([][]field.Field, error) {
if tx := ctx.GetTx(); tx != nil {
return tx.(*Driver).Where(tablename, fields, ctx.SetTx(nil), where, args...)
}
result := [][]field.Field{}

return nil, fmt.Errorf(
