To insert a complete record, pass to the insert() method all columns in the table. Then pass to the values() method one value for each column in the table. For example, to add a new record to the city table in the world_x schema, insert the following record and press Enter twice....
可以是S[,GAP], X[,GAP], IS[,GAP], IX[,GAP], AUTO_INC, UNKNOWN. 除了AUTO_INC and UNKNOWN的锁模式,其他的锁模式都暗含是GAP间隔锁 LOCK_TYPE 表示锁类型,可以是RECORD表示行锁, TABLE表示表锁 LOCK_TABLE 该锁涉及的表名 LOCK_INDEX 当为行锁时,则代表该锁涉及的索引名,否则为NULL. LOCK_SPACE...
