Package oracle.jdbc

Class OracleDatabaseMetaData

  • All Implemented Interfaces:
    DatabaseMetaData, Wrapper, AdditionalDatabaseMetaData, oracle.jdbc.internal.ACProxyable, oracle.jdbc.internal.AdditionalDatabaseMetaData, oracle.jdbc.internal.Monitor
    public class OracleDatabaseMetaData
extends Object
implements oracle.jdbc.internal.AdditionalDatabaseMetaData, oracle.jdbc.internal.Monitor
    The oracle.jdbc.OracleDatabaseMetaData class along with oracle.jdbc.driver.OracleDatabaseMetaData implement the JDBC 3.0 DatabaseMetaData interface and in ojdbc6.jar and above, the JDBC4.0 DatabaseMetaData interface. Note that the object returned by a call to java.sql.Connection.getMetaData() for a connection from the Oracle driver will be an instance of oracle.jdbc.driver.OracleDatabaseMetaData. There are several proprietary methods which are defined in this class. Only public long getLobMaxLength() will be retained in future versions. The following are superseeded by standard methods public static int getDriverMajorVersionInfo public static int getDriverMinorVersionInfo public static String getDriverVersionInfo and are deprecated. public String getLobPrecision() is no longer meaningful and is deprecated.

        Oracle Specific:

        The catalog argument is taken to mean a package name. Note that this is not a pattern and wildcards are not supported.

        Database synonyms may be defined (amoung other things) for a package, for an unpackaged procedure or for a synonym. The combination of synonyms and wildcards in the schemaPattern and procedureNamePattern is supported in a limited way due to complexity and performace issues.

        If the schemaPattern does not contain wildcards and the catalog argument is not null and not empty, the values are taken as either a schema + package name or a schema + synonym for a package. If it is a synonym, it will be resolved perhaps through multiple levels of synonyms and the search for the procedureNamePattern and columnNamePatten will be conducted in the resulting package.

        If the catalog is null and both the schemaNamePattern and procedureNamePattern do not contain wildcards, the values are taken as either a schema + procedureName or a schema + synonym. If it is a synonym it will be resolved perhaps through multiple levels of synonyms and the search for the columnNamePatten will be conducted in the resulting procedure

        13. REMARKS String => comment describing column/parameter
        14. CHAR_OCTET_LENGTH int => the maximum length of binary and character based parameters or columns. For any other datatype the returned value is a NULL
        15. ORDINAL_POSITION int => the ordinal position, starting from 1, for the input and output parameters. A value of 0 is returned if this row describes the function's return value. For result set columns, it is the ordinal position of the column in the result set starting from 1.
        16. IS_NULLABLE String => ISO rules are used to determine the nullability for a parameter or column.
          • YES --- if the parameter or column can include NULLs
          • NO --- if the parameter or column cannot include NULLs
          • empty string --- if the nullability for the parameter or column is unknown
        17. SPECIFIC_NAME String => the name which uniquely identifies this function within its schema. This is a user specified, or DBMS generated, name that may be different then the FUNCTION_NAME for example with overload functions

        The PRECISION column represents the specified column size for the given parameter or column. For numeric data, this is the maximum precision. For character data, this is the length in characters. For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component). For binary data, this is the length in bytes. For the ROWID datatype, this is the length in bytes. Null is returned for data types where the column size is not applicable.

        Note: If the user defined function in the database has failed to compile, this method returns an empty resultset.
