用asp.net动态创建的access表,如何设置其字段的“是否允许空字符串”、设置默认值???
谢谢!!
//
创建access数据库
ADOX.Catalog cat
=
new
ADOX.Catalog();
cat.Create(
"
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=
"
+
Server.MapPath(
"
~/
"
)
+
"
mydb/
"
+
this
.txtDB.Text
+
"
.mdb;Jet OLEDB:Engine Type=5
"
);
//
连接access数据库
ADODB.Connection conn
=
new
ADODB.Connection();
conn.Open(
"
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=
"
+
Server.MapPath(
"
~/
"
)
+
"
mydb/
"
+
this
.txtDB.Text
+
"
.mdb;Jet OLEDB:Engine Type=5
"
,
null
,
null
,

);
cat.ActiveConnection
=
conn;
ADOX.Table tb
=
new
ADOX.Table();
tb.Name
=
"
boss
"
;
ADOX.ColumnClass column
=
new
ColumnClass();
column.ParentCatalog
=
cat;
column.Name
=
"
id
"
;
column.Properties[
"
AutoIncrement
"
].Value
=
true
;
tb.Columns.Append(column, ADOX.DataTypeEnum.adInteger,
4
);
tb.Keys.Append(
"
FirstTablePrimaryKey
"
, ADOX.KeyTypeEnum.adKeyPrimary, column,
null
,
null
);
tb.Columns.Append(
"
Name
"
, ADOX.DataTypeEnum.adVarWChar,
50
);
tb.Columns.Append(
"
Pass
"
, ADOX.DataTypeEnum.adVarWChar,
50
);
ADOX.ColumnClass column1
=
new
ADOX.ColumnClass();
column1.Name
=
"
loginLast
"
;
column1.Properties["Jet OLEDB:Allow Zero Length"].Value =
false;
tb.Columns.Append(column1, ADOX.DataTypeEnum.adDBDate,
8
);
ADOX.ColumnClass column2
=
new
ADOX.ColumnClass();
column2.Name
=
"
indate
"
;
column2.Properties["Default"].Value =
"Now()";
tb.Columns.Append(column2, ADOX.DataTypeEnum.adDate,
8
);
cat.Tables.Append(tb);
conn.Close();
