All Implemented Interfaces:
DatabaseMetaData
public final class DatabaseMetaData
extends Object
implements DatabaseMetaData

This class provides general information about the Mimer database. Both database abilities and database schema is targeted.

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 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.

Please see {link java.sql.DatabaseMetaData} for information on methods in this class.

Method Detail

allProceduresAreCallable

public boolean allProceduresAreCallable()
                                 throws SQLException
Can all the procedures returned by getProcedures be called by the current user? Mimer always returns true.

Specified by:
allProceduresAreCallable in interface DatabaseMetaData
Returns:
true if so; false otherwise
Throws:
SQLException - if a database access error occurs

allTablesAreSelectable

public boolean allTablesAreSelectable()
                               throws SQLException
Can all the tables returned by getTable be SELECTed by the current user? Mimer always returns true.

Specified by:
allTablesAreSelectable in interface DatabaseMetaData
Returns:
true if so; false otherwise
Throws:
SQLException - if a database access error occurs

dataDefinitionCausesTransactionCommit

public boolean dataDefinitionCausesTransactionCommit()
                                              throws SQLException
Does a data definition statement within a transaction force the transaction to commit? Mimer returns false

Note. Mimer SQL executes DDL statement within transactions, but DML and DDL statements may not be mixed within the same transaction. If a DDL statement is issued in a transaction that previously had executed DML statements, an SQLException is thrown.

Specified by:
dataDefinitionCausesTransactionCommit in interface DatabaseMetaData
Returns:
true if so; false otherwise
Throws:
SQLException - if a database access error occurs

dataDefinitionIgnoredInTransactions

public boolean dataDefinitionIgnoredInTransactions()
                                            throws SQLException
Is a data definition statement within a transaction ignored? Mimer returns false.

Note. Mimer SQL executes DDL statement within transactions, but DML and DDL statements may not be mixed within the same transaction. If a DDL statement is issued in a transaction that previously had executed DML statements, an SQLException is thrown.

Specified by:
dataDefinitionIgnoredInTransactions in interface DatabaseMetaData
Returns:
true if so; false otherwise
Throws:
SQLException - if a database access error occurs

deletesAreDetected

public boolean deletesAreDetected(int type)
                           throws SQLException

Current Mimer SQL cursors are all completely stable (Mimer SQL cursors always achieve what is commonly known under the name "cursor stability"), which means that any updates or deletes performed by others are invisible.

Specified by:
deletesAreDetected in interface DatabaseMetaData
Returns:
true if changes are detected by the resultset type
Throws:
SQLException - if a database access error occurs

doesMaxRowSizeIncludeBlobs

public boolean doesMaxRowSizeIncludeBlobs()

public boolean supportsResultSetConcurrency(int type,
                                            int concurrency)
                                     throws SQLException
Does the database support the concurrency type in combination with the given result set type?

Mimer SQL supports both read only and updatable cursors. This routine will therefore return true for both ResultSet.CONCUR_READ_ONLY as well as ResultSet.CONCUR_UPDATABLE. However, note that Mimer SQL currently don't support updatable cursors through the JDBC API, but only using the corresponding SQL-99 updatable cursor operations.

Specified by:
supportsResultSetConcurrency in interface DatabaseMetaData
Parameters:
type - defined in java.sql.ResultSet
concurrency - type defined in java.sql.ResultSet
Returns:
true if so; false otherwise
Throws:
SQLException - if a database access error occurs

Connection

supportsResultSetType

public boolean supportsResultSetType(int type)
                              throws SQLException
Does the database support the given result set type?

Mimer SQL only supports a cursor mode commonly known under the the name "cursor stability". This means that once the cursor is created, it does never change. It will always reflect the state of the database at the time of creation. Thus, ResultSet.TYPE_FORWARD_ONLY ResultSet.TYPE_SCROLL_INSENSITIVE are supported while ResultSet.TYPE_SCROLL_SENSITIVE is not.

Specified by:
supportsResultSetType in interface DatabaseMetaData
Parameters:
type - defined in java.sql.ResultSet
Returns:
true if so; false otherwise
Throws:
SQLException - if a database access error occurs

supportsTransactionIsolationLevel in interface DatabaseMetaData
Parameters:
level - the values are defined in java.sql.Connection
Returns:
true if so; false otherwise

Are transactions supported? If not, invoking the method commit is a noop and the isolation level is TRANSACTION_NONE.

Mimer SQL always support the notion of transactions. Database administrators may, however, choose to place tables in so called "NULL databanks". These are databanks which does not expose full ACID characteristics. Also, changes to tables in these databanks are not logged. See Databank Options in the Mimer SQL System Management manual for more information about databank options.

Specified by:
supportsTransactions in interface DatabaseMetaData
Returns:
true if transactions are supported; false otherwise
Throws:
SQLException - if a database access error occurs

public boolean updatesAreDetected(int type)
                           throws SQLException
Indicates whether or not a visible row update can be detected by calling the method ResultSet.rowUpdated.

Current Mimer SQL cursors are all completely stable (Mimer SQL cursors always achieve what is commonly known under the name "cursor stability"), which means that any updates or deletes performed by others are invisible.

Specified by:
updatesAreDetected in interface DatabaseMetaData
Returns:
true if changes are detected by the result set type; false otherwise
Throws:
SQLException - if a database access error occurs

usesLocalFilePerTable

public boolean usesLocalFilePerTable()
                              throws SQLException
Does the database use a file for each table?

Mimer SQL will always store one or more tables in each databank (file system file), so this will always return false.

Specified by:
usesLocalFilePerTable in interface DatabaseMetaData
Returns:
true if the database uses a local file for each table
Throws:
SQLException - if a database access error occurs

usesLocalFiles

public boolean usesLocalFiles()
                       throws SQLException
Does the database store tables in a local file?

When Mimer is accessed using JDBC, the server always has to run in multiuser mode, and thus this always returns false.

Specified by:
usesLocalFiles in interface DatabaseMetaData
Returns:
true if so; false otherwise
Throws:
SQLException - if a database access error occurs
