 Posted: Fri Oct 15, 2010 7:40 pm Post subject: Missing Field from Where Clause |
 |
|
I'm using the compaire and passing it a where clause for each mapping. However, not all tabled have the field I'm using in the where clause. Is there a way to tell the comparer to ignore the where clause if it errors?
Or I guess the better question is how do I check the TableMapping if that particular where clause will be viable (ie if a certain field exists). |

Thanks for your query.
There isn't a particularly quick way of doing this, but one option is as below:
| Code: |
private static void AddWhereClause(TableMappings mappings)
{
foreach (TableMapping mapping in mappings)
{
if (mapping.Obj1.FullyQualifiedName=="[dbo].[ActionHistory]")
{
foreach (FieldMapping m in mapping.FieldMappings)
{
if (m.Obj1.Name == "ActionDate")
{
mapping.Include = true;
mapping.Where = new WhereClause("RecordID>=2");
}
}
}
else
{
mapping.Include = false;
}
}
}
|
In this instance, as I iterate around the mappings collection I'm checking for a certain table name. Within that check, I'm going through the fields collection to then see if a specific column exists.
You can perhaps tweak this so the column or table level check looks at your where clause to automate it to a certain extent.
Hope that helps. |
