CREATE TABLE sbtest%d(
id %s,
k INTEGER DEFAULT '0' NOT NULL,
c CHAR(120) DEFAULT '' NOT NULL,
pad CHAR(60) DEFAULT '' NOT NULL,
%s (id)
) %s %s]],
table_num, id_def, id_index_def, engine_def,
sysbench.opt.create_table_options)

correct create table statement
CREATE TABLE sbtest%d(
id %s,
k INTEGER NOT NULL DEFAULT '0',
c CHAR(120) NOT NULL DEFAULT '',
pad CHAR(60) NOT NULL DEFAULT '' ,
%s (id)
) %s %s]],
