create-table

问题 This SQL query is generated by SQL Server Managment Studio and it throws me an error: USE [database_name] GO /****** Object: Table [dbo].[UserAddress] Script Date: 02/17/2010 11:21:02 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[UserAddress] ( [ID] [int] IDENTITY(1,1) NOT NULL, [UserID] [int] NULL, [AddressName] [nvarchar](25) NULL, [Fname] [nvarchar](15) NULL, [LName] [nvarchar](20) NULL, [City] [nvarchar](15) NULL, [Street] [nvarchar]

问题 In the Enterprise version of SQL Server it is possible to generate the create statement for a pre-existing table by using 'Script Table as', "Create to". This generates the full create statement for the table including indices. Is there any way to do this in T-SQL and therefore be able to copy a table definition to a new table? 回答1: Nothing simply available out of the box in straight T-SQL which exactly replicates what SSMS does. However, you can get to this through the metadata ( INFORMATION

问题 I have 2 tables: Empleados(**numEmpl**, nombre, apellido, sexo, telefono, salario, numDept) Departamentos(**numDept**, nombreDept, numDirect) In departamentos: numEmpl is primary key numDept is foreign key reference to Departamentos(numDept). In departamentos: numDept is the primary key And numDirect is foreign key reference to Empleados (numEmpl) So there is a circular reference. First of all I created the Tables: CREATE TABLE EMPLEADOS(numEmpl primary key, nombre, apellido, sexo, telefono,

问题 I know that this has been asked hundreds of times before, but I looked around the Internet and couldn't find what could possibly be wrong with my syntax: mysql_select_db('Projects'); $sql = "CREATE TABLE $data[ID] ( ID INT NOT NULL, Creator INT NOT NULL, Name VARCHAR(20) NOT NULL, Version VARCHAR(20) NOT NULL, Status VARCHAR(20) NOT NULL, Date VARCHAR(20) NOT NULL, Skript VARCHAR(20) NOT NULL, Filename VARCHAR(20) NOT NULL, Downloads INT NOT NULL, PRIMARY KEY(ID) )"; if (mysql_query($sql)){

问题 How can I set the AUTO_INCREMENT on CREATE TABLE or ALTER TABLE from another table? I found this question, but not solved my issue: How to Reset an MySQL AutoIncrement using a MAX value from another table? I also tried this: CREATE TABLE IF NOT EXISTS `table_name` ( `id` mediumint(6) unsigned NOT NULL AUTO_INCREMENT, `columnOne` tinyint(1) NOT NULL, `columnTwo` int(12) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=(SELECT `AUTO_INCREMENT` FROM `INFORMATION

问题 I am trying to import data in the following format into a hive table [ { "identifier" : "id#1", "dataA" : "dataA#1" }, { "identifier" : "id#2", "dataA" : "dataA#2" } ] I have multiple files like this and I want each {} to form one row in the table. This is what I have tried: CREATE EXTERNAL TABLE final_table( identifier STRING, dataA STRING ) ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe' LOCATION "s3://bucket/path_in_bucket/" This is not creating a single row for each {} though. I

问题 I haven't used SQLite before and can't figure out the syntax, I have this working in SQL Server if it helps. I need to put the results into a temp table so I can reuse them. //SQL Server WITH FT_CTE AS ( SELECT pID, cID FROM brFTNode_Children WHERE pID = 1 UNION ALL SELECT e.pID, e.cID FROM brFTNode_Children e INNER JOIN FT_CTE ftCTE on (ftCTE.cID = e.pID) ) SELECT * INTO #ParentChild FROM FT_CTE; //SQLite try WITH FT_CTE AS ( SELECT pID, cID FROM brFTNode_Children WHERE pID = 1 UNION ALL

问题 I'm trying to setup temporary tables for unit-testing purposes. So far I managed to create a temporary table which copies the structure of an existing table: CREATE TEMP TABLE t_mytable (LIKE mytable INCLUDING DEFAULTS); But this lacks the data from the original table. I can copy the data into the temporary table by using a CREATE TABLE AS statement instead: CREATE TEMP TABLE t_mytable AS SELECT * FROM mytable; But then the structure of t_mytable will not be identical, e.g. column sizes and

问题 I have three tables in SQL and I need them to all be combined into one. I need all the fields from all the tables in the one table. All the tables contain the same fields just from three different years. I wrote a code that is: CREATE TABLE COL_TBL_TRAINING_ALL_YEARS AS( SELECT COL_TBL_2010_TRN_RESULTS_new.*, COL_TBL_TRN_RESULTS_GEMS_2011.*, COL_TBL_TRN_RESULTS_GEMS_2012.* FROM COL_TBL_2010_TRN_RESULTS_new, COL_TBL_TRN_RESULTS_GEMS_2011, COL_TBL_TRN_RESULTS_GEMS_2012 WHERE COL_TBL_2010_TRN
