MS SQL Server 2012；我有以下语法错误：“关键字“BEGIN”附近的语法不正确。”

我的SQL Server 2012存储过程出现语法错误：

CREATE PROCEDURE dbo.sp_UpdateOnHandQtyByMrchRcvd 
     (@pn_location_id SMALLINT, 
      @pn_item_id NUMERIC)

关键字“BEGIN”附近的语法不正确

以下是我的存储过程的代码：

CREATE PROCEDURE dbo.sp_UpdateOnHandQtyByMrchRcvd

            @p_trans_type_id INT,
            @p_trans_category_id INT,
            @p_trans_ref_id NUMERIC,
            @p_trans_type_code VARCHAR(35)

    -- reset item location qty
    UPDATE posit_db.dbo.item_location
    SET qty_on_hand = 0,
        updated_by = user_name(), 
        updated_date = getdate()
    WHERE location_id = @pn_location_id;

    -- Merchandise Received
    -- trans_type = MerRcvd, 10, trans_category = Purchase, 3
    DECLARE get_trans_data CURSOR FOR
        SELECT

                              @p_trans_category_id, @p_trans_ref_id, @p_qty, @p_trans_type_code

    WHILE (@@fetch_status <> -1)

应该是相反的。首先开始过程块，然后开始其中的事务块，反之亦然

create procedure dbo.sp_UpdateOnHandQtyByMrchRcvd (
BEGIN
BEGIN TRAN compute_inv_loc_bal;

编辑

我已经修改了我原来的答案

尝试构建存储过程时出现的错误是由于参数声明造成的。它们周围不应有开/闭括号。虽然不是必需的，但是您可能想考虑将存储过程的代码封装在开始/结束块中，尽管Dan Guzman用他的评论指出，它在语法上是可选的。此外，我会将BEGIN TRAN语句移动到变量声明之后，尽管这不是必需的

CREATE PROCEDURE dbo.sp_UpdateOnHandQtyByMrchRcvd
    @pn_location_id  smallint, 
    @pn_item_id      numeric
AS
BEGIN
    DECLARE @p_location_id        numeric,
            @p_item_id            numeric,
            @p_qty                numeric, 
            @p_on_hand_qty        numeric,
            @count                int,
            @p_trans_id           numeric,
            @p_trans_type_id      int,
            @p_trans_category_id  int,
            @p_trans_ref_id       numeric,
            @p_trans_type_code    varchar(35)

    BEGIN TRAN compute_inv_loc_bal;

    /* REMAINDER OF YOUR STORED PROCEDURE GOES HERE... */

END

开始/结束块不是必需的。中的方括号表示它们是可选的。虽然BEGIN/END是可选的，但根据我自己的经验，我强烈建议使用BEGIN/END以获得清晰性和更好的格式。旁注：您不应该在存储过程中使用sp_uu前缀。微软已经这样做了，而且你确实有可能在将来的某个时候发生名称冲突。最好只是简单地避免使用sp_uu，并使用其他东西作为前缀-或者根本不使用前缀早在25年前，在ANSI-92 SQL标准中，老式的逗号分隔表列表样式就被正确的ANSI连接语法所取代，不鼓励使用它。难道BEGIN TRAN不应该在BEGIN中吗？？？
