Two-phase commit support methods xid(format_id,gtrid,bqual) Y - tpc_begin(xid) Y - tpc_prepare() N 内核不支持显式prepare transaction。 tpc_commit([xid]) Y - tpc_rollback([xid]) Y - tpc_recover() Y - closed Y - cance
In the example above, I generated a new string based on the input values of two already-created variables by using thecurly brackets placeholderto show where the variables should be written. Then, I passed the variables as a parameter to the format method. On the other hand, we might want...
