如何基于MySQL中的现有表生成“创建表”命令？
您可以借助SHOWCREATE命令基于MySQL中的现有表生成createtable命令。
语法如下
SHOW CREATE TABLE yourTableName;
为了理解上述语法，让我们创建一个表。创建表的查询如下
mysql> create table StudentInformation - > ( - > StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, - > StudentName varchar(20), - > StudentAge int DEFAULT 18, - > StudentRollNo int, - > StudentAddress varchar(200), - > StudentMarks int, - > StudentDOB datetime, - > StudentAdmissionDate datetime - > );
现在，使用以上语法生成一个createtable命令。
查询如下
mysql> SHOW CREATE TABLE StudentInformation;
以下是输出
