本文介绍了我们可以使用变量名创建表而不是给出硬编码名吗?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我面临一个问题。我必须在syntax.so中使用proc输入参数值创建一个表。如何在不给出任何硬编码值的情况下这样做。



我尝试过:



CREATE PROC UPDATE_AUDIT_HISTORIC

(@ table_name varchar(50))

as

begin

- 检查GIVEN TABLE NAME的审计标志值

if(从config_table中选择audit_flag,其中table_name = @ table_name)='Y'

BEGIN

- 检查是否存在于表中的记录栏



IF(SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @ table_name)NOT IN('crt_dt','crt_by','mod_dt','mod_by')



ALTER TABLE @table_name ADD crt_dt DATE,crt_by VARCHAR(50),mod_dt DATE,mod_by DATE

END



--CHECKING hist_flag VALUE FOR GIVEN TABLE NAME

if(从config_table中选择hist_flag,其中table_name = @ table_name)=是'

BEGIN

- 检查历史记录表是否存在于数据库中并创建它

IF(SELECT COUNT(*)FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = @ table_name)= 0

BEGIN

CREATE TABLE Tbl_History



table_name_hist_ID int主键,

Table_name varchar(50),

column_s varchar(max)



END

结束

结束





这个我的proc如果运行这个proc我将是得到错误,如消息102,级别15,状态1,过程UPDATE_AUDIT_HISTORIC,第12行

'@ table_name'附近的语法不正确。



所以我们如何在create table语法中传递值..



这是错误行ALTER TABLE @table_name ADD crt_dt DATE,crt_by VARCHAR(50),mod_dt DATE, mod_by DATE。



这里我不能使用varible name如何创建一个表名相同的变量值...请帮助我。非常感谢...

I am facing one issue.i have to create one table using proc input parameter value in syntax.so how can we do that without giving any hardcode value.

What I have tried:

CREATE PROC UPDATE_AUDIT_HISTORIC
(@table_name varchar(50))
as
begin
--CHECKING AUDIT FLAG VALUE FOR GIVEN TABLE NAME
if (select audit_flag from config_table where table_name=@table_name)='Y'
BEGIN
--CHECKING AUDIT COLUMNS EXIST OR NOT IN THE TABLE

IF(SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=@table_name) NOT IN ('crt_dt', 'crt_by', 'mod_dt', 'mod_by')

ALTER TABLE @table_name ADD crt_dt DATE,crt_by VARCHAR(50),mod_dt DATE,mod_by DATE
END

--CHECKING hist_flag VALUE FOR GIVEN TABLE NAME
if (select hist_flag from config_table where table_name=@table_name)='Y'
BEGIN
--CHECKING HISTORY TABLE IS EXIST OR NOT IN THE DATABASE AND CREATE IT
IF(SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME=@table_name)=0
BEGIN
CREATE TABLE Tbl_History
(
table_name_hist_ID int primary key,
Table_name varchar(50),
column_s varchar(max)
)
END
END
END


this my proc if run this proc i would be getting error like Msg 102, Level 15, State 1, Procedure UPDATE_AUDIT_HISTORIC, Line 12
Incorrect syntax near '@table_name'.

So how we can pass the value in create table syntax..

this is the error line ALTER TABLE @table_name ADD crt_dt DATE,crt_by VARCHAR(50),mod_dt DATE,mod_by DATE.

Here i can't use varible name how can create a table same name of variale value..please assist me.any answer would be greatly appreciated...

推荐答案

DECLARE @table_name nvarchar(50);
DECLARE @CreateTable_SQL nvarchar(MAX);

SET @table_name='Sorry';
SET @CreateTable_SQL='CREATE TABLE '+@table_name+'(id int identity not null,toWhom nvarchar(50),why nvarchar(MAX),[Status] nvarchar(50) )';

EXEC(@CreateTable_SQL)

-- table created check it
INSERT INTO Sorry VALUES('S','that reason','Pending')

SELECT * FROM Sorry
