OdbcConnection.GetSchema Method (String, String)
Returns schema information for the data source of this OdbcConnection using the specified string for the schema name and the specified string array for the restriction values.
Assembly: System.Data (in System.Data.dll)
public override DataTable GetSchema( string collectionName, string restrictionValues )
- Type: System.String
Specifies the name of the schema to return.
- Type: System.String
Specifies a set of restriction values for the requested schema.
When collectionName is specified as null, the DataTable contains information about all the metadata that is available, and its restrictions.
The restrictionValues parameter can supply n depth of values which are specified by the restrictions collection for a specific collection. In order to set values on a given restriction, and not set the values of other restrictions, you must set the preceding restrictions to null and then put the appropriate value in for the restriction that you would like to specify a value for.
An example of this is the "Tables" collection. If the "Tables" collection has three restrictions (database, owner, and table name), and you want to get back only the tables associated with the owner "Carl," then you would need to pass in at least the following values: null, "Carl". If a restriction value is not passed in, the default values are used for that restriction. This is the same mapping as passing in null, which is different from passing in an empty string for the parameter value. In that case, the empty string ("") is considered to be the value for the specified parameter.
All restrictions that apply to SQLStatistics method will apply to the ODBCConnection.GetSchema("indexes") collection.
