MSSQL 'REPLACE' 附近的语法不正确

Question

我已经通过 liquibase 将 oracle 数据库迁移到 Microsoft SQL 服务器，但仍然有一些 SQL 语句不起作用。这个在 oracle 中看起来像这样：

CREATE OR REPLACE VIEW "BP_RESULTS_VIEW" (
BP_ID,                                     
RES_NAME,                                     
RES_LONG_NAME,                                     
MEDIAN,                                    
LOW_HINGE,                                 
HIGH_HINGE,                                
H_SPREAD,                                  
INNER_FENCE_LOW,                           
INNER_FENCE_HIGH,
OUTER_FENCE_LOW,
OUTER_FENCE_HIGH,
LOW_NOTCH,
HIGH_NOTCH,
LOW_ADJACENT_VALUE,
HIGH_ADJACENT_VALUE)
  AS 
SELECT 
r.BP_ID,                                     
rv.RES_NAME,                                     
rv.RES_LONG_NAME,                                     
r.MEDIAN,                                    
r.LOW_HINGE,                                 
r.HIGH_HINGE,                                
r.H_SPREAD,                                  
r.INNER_FENCE_LOW,                           
r.INNER_FENCE_HIGH,
r.OUTER_FENCE_LOW,
r.OUTER_FENCE_HIGH,
r.LOW_NOTCH,
r.HIGH_NOTCH,
r.LOW_ADJACENT_VALUE,
r.HIGH_ADJACENT_VALUE
FROM 
bp_results r, 
results_view_display rv 
WHERE 
CAST (rv.value AS INT) = r.bp_id AND 
rv.type = 'BOX';

将其迁移到 Microsoft SQL 服务器后，它看起来像这样：

CREATE OR REPLACE FORCE VIEW BP_RESULTS_VIEW (BP_ID, RES_NAME, RES_LONG_NAME, MEDIAN,
LOW_HINGE, HIGH_HINGE, H_SPREAD, INNER_FENCE_LOW, INNER_FENCE_HIGH,
OUTER_FENCE_LOW, OUTER_FENCE_HIGH, LOW_NOTCH, HIGH_NOTCH, 
LOW_ADJACENT_VALUE, HIGH_ADJACENT_VALUE) AS SELECT 
r.BP_ID,                                     
rv.RES_NAME,                                     
rv.RES_LONG_NAME,                                     
r.MEDIAN,                                    
r.LOW_HINGE,                                 
r.HIGH_HINGE,                                
r.H_SPREAD,                                  
r.INNER_FENCE_LOW,                           
r.INNER_FENCE_HIGH,
r.OUTER_FENCE_LOW,
r.OUTER_FENCE_HIGH,
r.LOW_NOTCH,
r.HIGH_NOTCH,
r.LOW_ADJACENT_VALUE,
r.HIGH_ADJACENT_VALUE
FROM 
bp_results r, 
results_view_display rv 
WHERE 
CAST (rv.value AS INT) = r.bp_id AND 
rv.type = 'BOX'
GO

但是当我想执行它时总是出现这个错误：

Incorrect syntax near 'REPLACE'.

我不明白为什么 SQL 服务器中也存在 REPLACE 语句。它似乎也无法识别 CAST 命令。我正在使用 Microsoft SQL Server Management Studio 17

Answer 1

SQL 服务器不支持 CREATE OR REPLACE VIEW.

相反，第一次创建视图。然后简单地使用ALTER VIEW。那是最简单的方法。您也可以删除视图并重新创建它。

Answer 2

在 SQL Server 2016 SP1 及更高版本（包括 Azure SQL 数据库）中，使用 CREATE OR ALTER VIEW 实现等效功能。在较早的 SQL 服务器版本中，必须先删除视图，然后再删除 CREATE VIEW 和 GRANT 权限。
