WIC项目_SAIO SQLCE DB manmger转换出现的问题

1 首先是表的字段名称不能是SQL的关键字符例如update、select等

//1 创建表 UserTb
CREATE TABLE UserTb(uid nvarchar(6) PRIMARY KEY,
pwd nvarchar(6) ,
privilege nchar(1)
);
------------------------------------------------------------
CREATE TABLE UserTb(uid nvarchar(6) PRIMARY KEY, pwd nvarchar(6) NOT NULL, privilege nchar(1) NOT NULL);
////////////////////////////////////////////////////////////



//2 创建表 APLTb
CREATE TABLE APLTb(upc nvarchar(17) PRIMARY KEY,
description nvarchar(50) ,
category nchar(2) ,
subcategory nchar(3) ,
punit nvarchar(10) ,
maxprice nchar(6) ,
ptype nchar(2)
);
------------------------------------------------------------
CREATE TABLE APLTb(upc nvarchar(17) PRIMARY KEY, description nvarchar(50), category nchar(2), subcategory nchar(3), punit nvarchar(10), maxprice nchar(6), ptype nchar(2));
////////////////////////////////////////////////////////////



//3 创建表 PriceTb
CREATE TABLE PriceTb (upc nchar(17) PRIMARY KEY,
price nchar(6)
);
------------------------------------------------------------
CREATE TABLE PriceTb (upc nchar(17) PRIMARY KEY, price nchar(6));
////////////////////////////////////////////////////////////



//4 创建表 ParamTb
CREATE TABLE ParamTb(pid smallint PRIMARY KEY,
pname nvarchar(30) ,
pvalue nvarchar(40)
);
------------------------------------------------------------
CREATE TABLE ParamTb(pid smallint PRIMARY KEY, pname nvarchar(30), pvalue nvarchar(40));
////////////////////////////////////////////////////////////



//5 创建表 TransTb
CREATE TABLE TransTb (traceid nchar(6) PRIMARY KEY,
msgtype nchar(4) ,
amount nchar(12) ,
uid nchar(4) ,
transdate nchar(6) ,
transtime nchar(6) ,
aiicode nvarchar(12)
);
------------------------------------------------------------
CREATE TABLE TransTb (traceid nchar(6) PRIMARY KEY, msgtype nchar(4), amount nchar(12), uid nchar(4), transdate nchar(6), transtime nchar(6), aiicode nvarchar(12));
////////////////////////////////////////////////////////////



//6 创建表 UpdateTb
CREATE TABLE UpdateTb(tid nchar(2) PRIMARY KEY,
tname nvarchar(20) ,
lupdate nchar (6) ,
luptime nchar (6)
);
-----------------------------------------------------------
CREATE TABLE UpdateTb (tid nchar(2) PRIMARY KEY, tname nvarchar(20), lupdate nchar(6), luptime nchar(6));
////////////////////////////////////////////////////////////


CString strCreate =_T("CREATE TABLE UserTb(uid nvarchar(6) PRIMARY KEY, pwd nvarchar(6) NOT NULL, privilege nchar(1) NOT NULL);");
test.ExecuteSQL(strCreate);

CString strCreate1 =_T("CREATE TABLE APLTb(upc nvarchar(17) PRIMARY KEY, description nvarchar(50), category nchar(2), subcategory nchar(3), punit nvarchar(10), maxprice nchar(6), ptype nchar(2));");
test.ExecuteSQL(strCreate1);

CString strCreate2 =_T("CREATE TABLE PriceTb (upc nchar(17) PRIMARY KEY, price nchar(6));");
test.ExecuteSQL(strCreate2);

CString strCreate3 =_T("CREATE TABLE ParamTb(pid smallint(2) PRIMARY KEY, pname nvarchar(30), pvalue nvarchar(40));");
if( test.ExecuteSQL(strCreate3))
{
MessageBox(NULL, _T("Insert OK"), _T("3"), MB_OK);
}
else
{
MessageBox(NULL, _T("Insert Fail"), _T("3"), MB_OK);
}

CString strCreate4 =_T("CREATE TABLE TransTb (traceid nchar(6) PRIMARY KEY, msgtype nchar(4), amount nchar(12), uid nchar(4), transdate nchar(6), transtime nchar(6), aiicode nvarchar(12));");
test.ExecuteSQL(strCreate4);

CString strCreate5 =_T("CREATE TABLE UpdateTb (tid nchar(2) PRIMARY KEY, tname nvarchar(20), lupdate nchar(6), luptime nchar(6));");
2 插入数据的时候要注意字段的长度
csPwd = CMd5::Encrypt(_T("123456"));
csSql.Format(_T("INSERT INTO UserTb(uid, pwd, privilege) VALUES(123456, '%s', 2);"), csPwd);
//pwd字段经过加密后变成32为MD5码，无法存储在只有6个字节的表中

if( test.ExecuteSQL(strCreate5))
{
MessageBox(NULL, _T("Insert OK"), _T("5"), MB_OK);
}
else
{
MessageBox(NULL, _T("Insert Fail"), _T("5"), MB_OK);
}
