Mysql Extract max number from a string












0















Do you know if there is any manner to extract maximum number into a string in MySql ?



My table looks like this:



+-----------------------------------------------------------+
| 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 |
+-----------------------------------------------------------+


Desired output:



55.0
97.70
