最近在折腾greenplum,遇到一个蛋疼的问题,那就是获取表结构,也就是建表语句.大家都知道在MySQL里面是非常easy的,show create table table_name 就搞定了,在gpdb里面就没这么容易,在查询大量资料以后终于找到了方法.那就是自己定义一个函数去获取,函数中可以嵌套python代码,非常的方便.但是资料中的代码有大量错误,在经过几番调试以后终于可以使用了. 如果没有这个函数其实也可以获取表结构,那就是只能导出这个表的结构进行查看了.导出表结构的命令是: pg_

sqlserver 复制表结构(可以含有数据 或 只要表结构) SELECT * INTO bb FROM aa(NOLOCK) WHERE 1=0

Sql中获取表结构(字段名称,类型,长度,说明) SELECT TableName = OBJECT_NAME(c.object_id), ColumnsName = c.name, Description = ex.value, ColumnType=t.name, Length=c.max_length FROM sys.columns c LEFT OUTER JOIN sys.extended_properties ex ON ex.major_id = c.object_id AND

1.MySql获取表结构信息 SELECT TABLE_NAME, TABLE_COMMENT FROM information_schema.`TABLES` WHERE TABLE_SCHEMA = 'dm' -- dm 是数据库名称,需替换 ORDER BY TABLE_NAME; 2.MySql获取字段信息 SELECT TABLE_NAME AS 'tableName', COLUMN_NAME AS 'columnName', COLUMN_COMMENT AS 'columnCom

1.获取表结构的DDL语句 2.获取修改表结构某一字段的DDL语句  设计表-修改表字段(记住不要保存)-SQL预览

Sql Server(sybase): 1．复制表结构: 新建表student2,并且结构同表syn_xj_student一致.Sql语句如下: 2．复制表数据,并排除俩表中相同的数据: insert into syn_xj_student2 select * from syn_xj_student where f_id not in (select f_id from syn_xj_student2) mysql: 1．复制表结构: create table topic like bbs_to

一.获取表的基本信息 SELECT [TableName] = [Tables].name , [TableOwner] = [Schemas].name , [TableCreateDate] = [Tables].create_date , [TableModifyDate] = [Tables].modify_date FROM sys.tables AS [Tables] INNER JOIN sys.schemas AS [Schemas] ON [Tables].schema_id

通过Oracle中的user_tab_cols, user_col_comments, user_constraints, user_cons_columns表联合查询. user_tab_cols用来获取对应用户表的列信息: user_col_comments用来获取对应用户表列的注释信息: user_constraints用来获取用户表的约束条件: user_cons_columns约束中用户可访问列. select a.column_id as 列号, a.column_name as 列

SQlserver获得列名,列类型,列类型长度,scale,prec等数据类型(syscolumns,systypes,sysobjects均为视图) select a.name as colname, b.name as typename,a.length as length,a.scale as scale,a.prec as prec from syscolumns a,systypes b ,sysobjects c where a.xusertype=b.xusertype and a

只说原理了,具体 可以自己使用程序去生成htm或word文档. 1.首先获取所有的表 SELECT name, id From sysobjects WHERE xtype = 'u' ORDER BY name ASC 2.根据表名查询字段信息 select syscolumns.name, syscolumns.length, systypes.name   as   typename, sys.extended_properties.[value] AS tname,syscolumns.
