你知道在mysql中有没有办法把最大值提取到字符串中？
我的table是这样的：

+-----------------------------------------------------------+
| Freq                                                      |
+-----------------------------------------------------------+
| 40.56                                                     |
| 99.51                                                     |
| 99.87                                                     |
| T=0.00, TCCA=0.00, TTCC=0.03, TTCG=0.00, TTCT=55.0        |
| C=97.70, T=0.05                                           | 
| 44.61                                                     |
| 57.45                                                     |
| 38.18                                                     |
| 38.43                                                     |
| 39.36                                                     |
| 38.65                                                     |
| 39.30                                                     |
| C=57.53, T=0.17                                           |
| TAAAAAAAAAAA=0.51, TAAAAAAAAAA=68.03, TAAAAAAAAAAAG=31.42 |
+-----------------------------------------------------------+

期望输出：

55.0
97.70
