Question

我想从table1向表2传输50行，我该怎么做？

建议代码：

    INSERT INTO table2 SELECT * FROM table1 
    WHERE uid IN ('23','34','345','567','3242','34322','2') DELETE;

Answer 1

写2条陈述。如果您使用InnoDB，请将它们放在一个事务中：

START TRANSACTION ;

INSERT INTO table2 
  SELECT * 
  FROM table1 
  WHERE uid IN ('23','34','345','567','3242','34322','2') ;

DELETE FROM table1 
WHERE uid IN ('23','34','345','567','3242','34322','2') ;

COMMIT ;

Answer 2

INSERT INTO table1 (col1, col2, col3) SELECT col1, col2, col3 FROM table2 WHERE col4='some value'

Answer 3

INSERT INTO TABLE2 SELECT * FROM TABLE1 WHERE COL1 = 'A'
