OracleConnection.GetSchema Method (String)
Returns schema information for the data source of this OracleConnection using the specified string for the schema name.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
Queries using GetSchema are case sensitive. Because of Oracle's treatment of cases when a schema is first created, this can lead to unexpected results.
If the schema was created without quotes, Oracle stores the object name in upper case. If the schema was created with quotes, Oracle stores the object name in the casing provided.
For example, suppose that you create a table called MyTable, using one of the following two statements:
CREATE TABLE MyTable ...
CREATE TABLE "MyTable" ...
To retrieve information about this table via the GetSchema method in the first case, you would have to pass "MYTABLE" in as an argument. In the second case, you would have to pass "MyTable" in as an argument.
