Class DatabaseMetaData

    java.lang.Object
      |
      +--interbase.interclient.DatabaseMetaData

All Implemented Interfaces:
  DatabaseMetaData

public final class DatabaseMetaData
extends Object
implements DatabaseMetaData

Provides information about the database or connection, as well as database capabilities.

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 will throw a 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 1, with extended behavior in JDBC 2

### getDatabaseSQLDialect

    public int getDatabaseSQLDialect()

  Gets the SQL Dialect level of this database. The SQL Dialect of a database indicates which SQL features are available to clients connecting at that SQL Dialect level. As more features are added to database server, such as new datatypes and syntax enhancements, new SQL Dialect levels are introduced. Users can establish connections that take advantage of the newest features (using a high SQL dialect) or establish one that maintains compatability with older versions of the server (using lower SQL Dialects). SQL Dialect levels available with InterBase 6.0: Dialect 1 maintains compatability with databases created with InterBase versions 5.x. With this dialect, the DATE datatype holds both date and time values, NUMERIC and DECIMAL datatypes with a precision greater than 9 are represented internally by double precision floating-point values. String literals can be delimited by either single quotes (') or double quotes ("). InterBase 5 databases are always dialect 1. Dialect 2 is a transition dialect, used to help you migrate the data in a dialect 1 database to dialect 3. Dialect 3 introduces new features and is available only with InterBase version 6.0 or higher. With dialect 3, the DATE datatype represents only the date portion of a timestamp, TIME represents only time, and TIMESTAMP represents both date and time values (as did the DATE datatype in dialect 1). NUMERIC and DECIMAL types with precisions between 10 and 18, inclusive, are represented internally by 64-bit integers. Values appearing within single quotes (') are presumed to be string literals; whereas values appearing in double quotes (") are presumed to be identifiers (identifying the names of tables, columns, views, procedures, roles, triggers, and the like).

    SQL Dialect for the database

  InterClient note: Return 31 for InterBase.

  Specified by:
    `getMaxCursorNameLength` in interface `DatabaseMetaData`

  Throws:
    `SQLException` - if a database access error occurs.
  Since:

### getMaxIndexLength

    public int getMaxIndexLength()
                          throws SQLException

  What's the maximum length of an index (in bytes).

  InterClient notes:
  Returns 198 bytes, but see comments below.

  Actually, there is no single hard-code value for this. We can calculate the maximum size as follows. We have 256 bytes to fill, but that has to include column indicators as well as any column padding. If the 256 bytes were filled, 1/5 or 51 bytes would be column indicators. There is then one slop byte which is good for nothing; we could fill it with a column indicator, but it would have nothing to indicate. Then there's the padding: in the worst case we would have 3 bytes of padding for each column.

  So a calculation of the maximum amount of user data which could fit in an index key is as follows:

       256 available bytes - 1 slop byte - 51 column indicator bytes - 3 * number columns

  So the maximum length you can have for a multi-column index is as follows:

       2 columns:  198 bytes
       3 columns:  195 bytes
       4 columns:  192 bytes

  and so on. Note that your mileage may vary. You may get up to an additional 3*n bytes for an n-column index, if all columns happen to round to a multiple of 4 bytes long. But I wouldn't count on it. Best to publish these as hard limits.

  INTERNATIONAL ISSUES

  The maximum number of characters you can fit in an index varies depending on the character set. The above calculations give the number of bytes, which is good for ASCII data. Multibyte character sets can get sticky. Customers interested in internationalization will have to know the length of their keys in bytes, not characters.

                                                  throws SQLException

  Does a data definition statement within a transaction force the transaction to commit.

  InterClient note: Returns true for InterClient. InterClient does not follow the ISQL transaction model. Under the ISQL transaction model, in a mixed DDL/DML transaction, the DDL is autocommitted even if you're not in autocommit mode, but the DML is not autocommitted. So if a rollback occurs, only the DML is rollbacked, hence a mixed DDL/DML transaction is not atomic. Under the InterClient transaction model for a mixed DDL/DML transaction, any DDL forces the entire transaction to commit implicitly, this includes all DML up to and including the DDL atomically.

  Specified by:
    `dataDefinitionCausesTransactionCommit` in interface `DatabaseMetaData`
  Returns:
    true if so
  Throws:
    `SQLException` - if a database access error occurs.

                                 throws SQLException

  Get a description of the access rights for each table available in a catalog. Note that a table privilege applies to one or more columns in the table. It would be wrong to assume that this priviledge applies to all columns (this may be true for some systems but is not true for all.)

  Only privileges matching the schema and table name criteria are returned. They are ordered by TABLE_SCHEM, TABLE_NAME, and PRIVILEGE.

  Each privilige description has the following columns:

  1. TABLE_CAT String => table catalog (may be null)
  2. TABLE_SCHEM String => table schema (may be null)
  3. TABLE_NAME String => table name
  4. GRANTOR => grantor of access (may be null)
  5. GRANTEE String => grantee of access
  6. PRIVILEGE String => name of access (SELECT, INSERT, UPDATE, REFRENCES, ...)
  7. IS_GRANTABLE String => "YES" if grantee is permitted to grant to others; "NO" if not; null if unknown

  InterClient note: A SQLException is thrown if a catalog or schema pattern is given.

  Specified by:
    `getTablePrivileges` in interface `DatabaseMetaData`
  Parameters:
    `catalog` - a catalog name; "" retrieves those without a catalog; null means drop catalog name from the selection criteria
    `schemaPattern` - a schema name pattern; "" retrieves those without a schema
    `tableNamePattern` - a table name pattern
  Returns:
    ResultSet - each row is a table privilege description
  Throws:
    `SQLException` - if a database access error occurs.
