Timothy Flynn aec75d749a LibSQL+SQLServer+SQLStudio+sql: Allocate per-statement-execution IDs
In order to execute a prepared statement multiple times, and track each
execution's results, clients will need to be provided an execution ID.
This will create a monotonically increasing ID each time a prepared
statement is executed for this purpose.
