在SQL Server中生成**承载** CREATE TABLE和CREATE PROC语句

我公司的部署过程要求用于创建过程和表等的SQL脚本是裸露的。

在SQL Server Management Studio中生成创建脚本不仅仅是一个裸脚本，在这种情况下很不幸。例如，对于测试表，这就是SSMS为我生成的内容：

USE [DemoDB]
GO

/****** Object:  Table [dbo].[example]    Script Date: 08/07/2012 15:46:32 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[example](
    [fake_row] [int] NULL
) ON [PRIMARY]

GO

所以，我想知道的是：

我可以以某种方式在SSMS中运行SQL Server上的查询，它会给我一个字面上只有以下内容的脚本吗？

create table example (
    fake_row int
)

您可以使用information_schema（Aaron ...我知道，INFORMATION_SCHEMA;）创建您自己的“创建表”语句。

我为此目的编写了一些代码，但它没有使用INFORMATION_SCHEMA。我知道，如果使用可能计划删除的旧系统表。它还添加了一些额外的信息（您可以删除，因为您不需要它）。只需将表列表放在@INclusiveLIST中，然后在表所在的数据库中运行它。

SET @INCLUSIONLIST = '|table1|table2|';

SELECT (CASE WHEN rownum = 1 THEN 'CREATE TABLE ['+a.t_name+'] ('
             WHEN c.column_id IS NOT NULL
             THEN '    ['+c.c_name+'] ' +
                  (CASE WHEN CHARINDEX('CHAR', datatype) > 0 THEN datatype+'('+(case when length < 0 then 'max' else cast(length as varchar) end)+')'
                        WHEN CHARINDEX('BINARY', datatype) > 0 THEN datatype+'('+cast(length as varchar)+')'
                        WHEN datatype = 'float' AND precision <> 24 THEN datatype+'('+cast(precision as varchar)+')'
                        WHEN datatype IN ('numeric', 'decimal') AND scale = 0 THEN datatype+'('+cast(precision as varchar)+')'
                        WHEN datatype IN ('numeric', 'decimal') AND scale > 0 THEN datatype+'('+cast(precision as varchar)+','+cast(scale as varchar)+')'
                        ELSE datatype END)+' '+
                  (CASE WHEN c.identity_seed IS NOT NULL
                        THEN 'IDENTITY(' + CAST(identity_seed AS VARCHAR) + ',' + CAST(identity_increment AS VARCHAR) + ') '
                        ELSE '' END) +
                  (CASE WHEN c.is_nullable = 0 THEN 'NOT NULL ' ELSE '' END) +
                  (CASE WHEN c.default_definition IS NOT NULL
                        THEN 'DEFAULT '+default_definition ELSE '' END) +
                  (CASE WHEN max_column_id = column_id AND pk.pk_name IS NULL THEN '' ELSE ',' END)
            WHEN rownum = max_column_id + 2 and pk.pk_name IS NOT NULL
            THEN '    PRIMARY KEY ('+pk.pk_columns+')'
            WHEN rownum = max_column_id + 3 THEN ')  /* CREATE TABLE '+a.t_name+' */'
            WHEN rownum = max_column_id + 4 THEN 'GO'
            WHEN rownum = max_column_id + 5 THEN ''
        END)
 FROM (SELECT t.t_name, rownum, max_column_id
       FROM (SELECT t.name as t_name, MAX(c.column_id) as max_column_id
             FROM sys.columns c join

为自我答案道歉，标记其他好的答案+1。

事实证明，你可以在SSMS中使用实用工具。

  1. 右键单击对象资源管理器中的数据库
  2. 点击“任务”
  3. 点击“生成脚本”
  4. 选择“脚本特定对象”并选择表格或其他
  5. 选择“保存到文件”＆amp; “每个对象的单个文件”（或只是查询窗口的假脱机）
  6. 单击“高级”，您可以启用/禁用生成的几乎所有语句的生成，包括约束，使用语句等。
  7. 如果需要进一步删除（例如删除GO），那么它是最小的

您可以选择控制SSMS的常规脚本行为，如：Options for scripting SQL Server database objects。

答案 3 :(得分：1)

我会创建从INFORMATION_SCHEMA视图中读取的存储过程。 获取存储过程文本只是：

    DECLARE @SQL VARCHAR(8000)
    SET @SQL=' '

    select  @SQL = @SQL + ROUTINE_DEFINITION
    from INFORMATION_SCHEMA.ROUTINES
    where ROUTINE_TYPE='PROCEDURE'
    AND SPECIFIC_NAME = 'updateComments'

    PRINT @SQL

脚本表的那个看起来像：

DECLARE @tableName VARCHAR(50)
SET @tableName = 'Location' 

-- Need to know how many columns 
DECLARE @NumColumns int
SELECT @NumColumns = MAX(ORDINAL_POSITION)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = @tableName

DECLARE @SQL VARCHAR(8000)
SET @SQL=' '

DECLARE @Results TABLE 
(LineNumber int, 
Line VARCHAR(1000))


INSERT INTO @Results
    SELECT 0 AS ORDINAL_POSITION, 
    'CREATE TABLE '+TABLE_SCHEMA+'.'+@tableName+' (' AS Line
    FROM INFORMATION_SCHEMA.TABLES
    WHERE TABLE_NAME = @tableName

    UNION ALL

    SELECT ORDINAL_POSITION, 
    '['+COLUMN_NAME+'] '+ DATA_TYPE + 
    CASE WHEN DATA_TYPE = 'varchar' OR DATA_TYPE = 'char' 
    THEN '('+ CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR) +')'
    ELSE '' END +
    CASE WHEN IS_NULLABLE = 'NO' 
    THEN ' NULL '
    ELSE ' NOT NULL' END +
    CASE WHEN ORDINAL_POSITION < @NumColumns 
    THEN ', '
    ELSE ' ' END
    AS LINE
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE TABLE_NAME = @tableName

    UNION ALL

    SELECT 999, ' )'


SELECT Line
FROM @Results
ORDER BY LineNumber


SELECT @SQL = @SQL + Line
FROM @Results
ORDER BY LineNumber

SELECT @SQL
PRINT @SQL

这会创建您想要的简单表脚本，但它不完整 - 不执行数字精度，主键等。但这足以让您入门。

我只是将其中的每一个都变成一个以对象名作为参数的存储过程。
