示例1: readCmd
// readCmd reads a value from the db and stores it in the env.
func readCmd(c *cmd, txn *client.Txn, t *testing.T) *roachpb.Error {
r, pErr := txn.Get(c.getKey())
if pErr != nil {
return pErr
}
if r.Value != nil {
c.env[c.key] = r.ValueInt()
c.debug = fmt.Sprintf("[%d ts=%d]", r.ValueInt(), r.Timestamp())
}
return nil
}
示例2: readCmd
// readCmd reads a value from the db and stores it in the env.
func readCmd(c *cmd, txn *client.Txn, t *testing.T) error {
r, err := txn.Get(c.getKey())
if err != nil {
return err
}
var value int64
if r.Value != nil {
value = r.ValueInt()
}
c.env[c.key] = value
c.debug = fmt.Sprintf("[%d]", value)
return nil
}
示例3: resolveName
// resolveName resolves a table name to a descriptor ID by looking in the
// database. If the mapping is not found, errDescriptorNotFound is returned.
func (m *LeaseManager) resolveName(
txn *client.Txn, dbID sqlbase.ID, tableName string,
) (sqlbase.ID, error) {
nameKey := tableKey{dbID, tableName}
key := nameKey.Key()
gr, err := txn.Get(key)
if err != nil {
return 0, err
}
if !gr.Exists() {
return 0, errDescriptorNotFound
}
return sqlbase.ID(gr.ValueInt()), nil
}
