从DataSet创建SQL Server数据库

Question

I read xsd and xml file in DataSet , now I want create db from this DataSet

foreach (DataTable dt in temp.Tables) {
    foreach (DataColumn dc in dt.Columns) {
        //example for one column
        SqlCommand createtable = new SqlCommand(
            "create table " + dt.TableName + " (" 
            + dc.ColumnName + "  varchar(max))", conn);
        createtable.ExecuteNonQuery();
    }
}

But I have some problem, when I create db table I need column type and size from XSD (in example use varchar(max) ). How to fix this?

For example in xsd I have

<xs:restriction base="xs:string">
<xs:maxLength value="36"/>
<xs:minLength value="1"/>
</xs:restriction>

or

<xs:restriction base="xs:string">
<xs:maxLength value="40"/>
</xs:restriction>

or

<xs:restriction base="xs:decimal">
<xs:totalDigits value="19"/>
<xs:fractionDigits value="2"/>
</xs:restriction>

In the end I need script to create db tables with size of columns (like in xsd)

UPD: Maybe use XmlSchemaSet to parse XSD?

Answer 1

use XSD2DB

XSD2DB is a command line tool written in C# , that will read a Microsoft ADO.NET compatible DataSet Schema File (XSD) and generate a database.

I guess there's no general solution to this. An XSD can easily describe something that does not map to a relational database.While you can try to "automate" this, your XSD's must be designed with a relational database in mind, or it won't work out well.

However you can transfer your datatables in memory to sql server database using SQLServer Management Objects and SqlBulkCopy .

Please refer to this link for more information. Hope this may help you.

Answer 3

Would scaffolding be able to help you in this situation?

Maybe take a look at that, I know there was a way of doing a reverse engeneering of the database first with scaffolding
