事务问题

写了一个事务,执行一级动态生成的SQL


CREATE PROCEDURE L_InsertNew
@strSql1 varchar(5000),
@strSql2 varchar(5000),
@strSql3 varchar(5000),
@intOut int output
AS
SET NOCOUNT ON
begin tran
exec(@strSql1)
exec(@strSql2)
exec(@strSql3)
if @@Error <> 0 or @@rowcount = 0 goto ErrMsg
set @intOut=1
commit
ErrMsg:
set nocount off
rollback tran
set @intOut=0 --添加失败并回滚


GO

在VB中执行,调用过程
With comCommand
.ActiveConnection = g_conConnection2
.CommandType = adCmdStoredProc
.CommandText = "L_InsertNew"
.Parameters("@strSql1") = strSql1
.Parameters("@strSql2") = strSql2
.Parameters("@strSql3") = strSql3
.Execute
但是执行到2,3时,出现错误,生成的语句如下:

insert into ICInventory(FBatchNo,fitemid,fstockid,fqty,fbrno) values ('',5563,14480,'1',0)
insert into ICInventory(FBatchNo,fitemid,fstockid,fqty,fbrno) values ('',5567,14480,'65.6',0)
insert into ICInventory(FBatchNo,fitemid,fstockid,fqty,fbrno) values ('',14027,14480,'212.8',0)

出现错误:应用程序在当前操作中使用了错误类型的值
