IfxDatabaseMetaData (informix-jdbc 4.10.16.2 API)

java.lang.Object
- com.informix.jdbc.IfxDatabaseMetaData

All Implemented Interfaces:

java.sql.DatabaseMetaData, java.sql.Wrapper
```
public class IfxDatabaseMetaData
extends java.lang.Object
implements java.sql.DatabaseMetaData
```
This class provides information about the database as a whole.
Many of the methods here return lists of information in ResultSets. You can use the normal ResultSet methods such as getString and getInt to retrieve the data from these ResultSets. If a given form of metadata is not available, these methods should throw an SQLException.
Some of these methods take arguments that are String patterns. These arguments all have names such as fooPattern. Within a pattern String, "%" means match any substring of 0 or more characters, and "_" means match any one character. Only metadata entries matching the search pattern are returned. If a search pattern argument is set to a null ref, it means that argument's criteria should be dropped from the search.
A SQLException will be thrown if a driver does not support a meta data method. In the case of methods that return a ResultSet, either a ResultSet (which may be empty) is returned or a SQLException is thrown.

    JDBC 2.0 Get a description of the user-defined types defined in a particular schema. Schema specific UDTs may have type JAVA_OBJECT, STRUCT, or DISTINCT.
    Only types matching the catalog, schema, type name and type criteria are returned. They are ordered by DATA_TYPE, TYPE_SCHEM and TYPE_NAME. The type name parameter may be a fully qualified name. In this case, the catalog and schemaPattern parameters are ignored.
    Each type description has the following columns:
    1. TYPE_CAT String => the type's catalog (may be null)
    2. TYPE_SCHEM String => type's schema (may be null)
    3. TYPE_NAME String => type name

    Note: If the driver does not support UDTs then an empty result set is returned.
