sql-server - SQL 错误 : Incorrect syntax near the keyword 'End'

Question

需要有关此 SQL Server 2000 过程的帮助。这个问题很困难，因为我正在通过 Oracle SQL Developer 测试程序。

我正在运行该过程，为那些具有空值的人使用 Varchar 格式的新数字序列迭代列。

但我不断收到错误，所以 a) 我可能做错了 b) 由于使用的版本，语法不正确。我主要是 Oracle 用户。

我不断收到错误:SQL Error: Incorrect syntax near the keyword 'End'.这不足以解决问题。 End指程序中的最后一个“结束”。

任何帮助将不胜感激。

这是程序。

ALTER PROCEDURE [dbo].[OF_AUTOSEQUENCE] @JvarTable Varchar(250), @varColumn Varchar(250), @optIsString char(1), @optInterval int AS
/*
Procedure   OF_AUTOSEQUENCE
Created by  Joshua [Surname omitted]
When        20100902

Purpose     To fill up column with new sequence numbers
Arguments   varTable    - Table name
            varColumn   - Column name
            optIsString - Option: is it string or numeric, either use T(rue) or F(alse)
            optInterval - Steps in increment in building new sequence (Should be 1 (one))

Example script to begin procedure

EXECUTE [dbo].[OF_AUTOSEQUENCE] 'dbo.EH_BrownBin', 'Match', 'T', 1

你缺少一个 begin紧跟在 WHILE 之后.你缩进就像你想要在 while 循环中的一个块(多个语句)，甚至还有一个 end为 while ，但没有 begin .

做了:

...
  open MyCur
  fetch next from MyCur
  WHILE @@FETCH_STATUS = 0
  begin --<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<add this
    set @topseed = @topseed + @optInterval
    if @optIsString = 'T'
      begin
        set @Sql_string = 'update ' + @JvarTable + ' set ' + @varColumn + ' = cast((' + @topseed + ') as char) where current of ' + MyCur
        exec (@Sql_string)
      ENd
    else
      begin
        set @Sql_string = 'update ' + @JvarTable + ' set ' + @varColumn + ' = ' + @topseed + ' where current of ' + MyCur
        exec (@Sql_string)
      ENd
    fetch next from MyCur
  ENd
...
