Herunterladen Postgresql 9 Jdbc Driver For Mac

1108

I'm trying to install the jdbc driver on my Mac OS X Lion installation. I'm running JRE 1.6.0_26. I've downloaded postgresql-9.0-801.jdbc4.jar. Caigen CSV JDBC Driver was designed to enable users to perform SQL operations on raw data, flat text, TSV files, CSV files, PSV files, fixed-length, and variable-length binary files. It supports data mining on memory database, compressed databas.

PostgreSQL JDBC for macOS This tutorial shows how to set up a data source and connect to a PostgreSQL database using the Database Explorer app or the command line. This tutorial uses the JDBC4 PostgreSQL Driver, Version 8.4 to connect to a PostgreSQL 9.2 database.

Step 1. Verify the driver installation. If the JDBC driver for PostgreSQL is not installed on your computer, find the link on the page to install the driver. Follow the instructions to download and install this driver on your computer.

Add the JDBC driver to the MATLAB static Java class path. Run the prefdir function in the Command Window. The output of this command is a file path to the MATLAB ® preferences folder on your computer. For details, see. Close MATLAB.

Navigate to the folder from step 1, and create a file named javaclasspath.txt in the folder. Open javaclasspath.txt.

Add the full path to the database driver JAR file in javaclasspath.txt. The full path includes the path to the folder where you downloaded the JAR file from the database provider followed by the JAR file name. The following is an example of the path: /home/user/DBDrivers/postgresql-8.4-702.jdbc4.jar. Save and close javaclasspath.txt.

Restart MATLAB. Alternatively, you can use to add a JDBC driver to the dynamic Java ® class path. For details about static and dynamic class paths, see (MATLAB). Set up the data source using the Database Explorer app. This step is required only for connecting to a database using the Database Explorer app. If you want to use the command line to connect to your database, see.

In the Database box, enter the name of your database. In the Server box, enter the name of your database server. Consult your database administrator for the name of your database server. In the Port Number box, enter the port number. Click Test.

The Test Connection dialog box opens. Enter the user name and password for your database, or leave these boxes blank if your database does not require them. If your connection succeeds, the Database Explorer dialog box displays a message indicating the connection is successful.

Otherwise, it displays an error message. Click Save.

The JDBC Data Source Configuration dialog box displays a message indicating the data source is saved successfully. Close this dialog box. After you complete the data source setup, connect to the PostgreSQL database using the Database Explorer app or the command line with the JDBC connection.

Connect using the Database Explorer app or the command line. Connect to PostgreSQL Using Database Explorer App. On the Database Explorer tab, in the Data Source section, click New Query. In the Connect to a Data Source dialog box, select the data source you defined from the Data Source list.

Enter a user name and password, or leave these boxes blank if your database does not require them. Click Connect. The Catalog and Schema dialog box opens. Select the catalog and schema from the Catalog and Schema lists.

The Database Explorer app connects to the database and displays database tables in the Data Browser pane. A data source tab appears to the right of the pane. The title of the data source tab is the data source name that you defined during the setup. The data source tab contains empty SQL Query and Data Preview panes. Select tables in the Data Browser pane to query the database. Close the data source tab to close the SQL query and the database connection.

Tip To close the database connection, close all tabs that have titles beginning with the name of the corresponding data source. For example, if the data source name is PostgreSQL, and two tabs named PostgreSQL and PostgreSQL1 are open, then close both tabs. To close all database connections, close the Database Explorer app.

Postgresql

Connect to PostgreSQL Using JDBC Driver and Command Line When using the command line, you do not have to set up a data source with the Database Explorer app. You can use the command line to pass all the required parameters for connection.

Add a MainClass that tells the user they can't just run the JDBC driver After one too many reports of 'Failed to load Main-Class manifest attribute from postgresql-xxx.jar' I'm submitting a dummy main-class that tells the user what they should do instead. The message looks like: - PostgreSQL x.y JDBC4.1 (build bbbb) Found in: jar:file:/path/to/postgresql-x.y-bbbb.jdbc41.jar!/org/postgresql/Driver.class The PgJDBC driver is not an executable Java program.

You must install it according to the JDBC driver installation instructions for your application / container / appserver, then use it by specifying a JDBC URL of the form jdbc:postgresql:// or using an application specific method. See the PgJDBC documentation: This command has had no effect. fixed bug PreparedStatement.getMetaData failed if result set was closed reported by Emmanuel Guiton Author: cchantep Date: Thu Dec 12 15: +0100. Fix various setQueryTimeout bugs. If you call setQueryTimeout(5), wait 10 seconds, and call execute, the cancel timer has already expired, and the statement will be allowed to run forever. Likewise, if you call setQueryTimeout(5), wait 4 seconds, and call execute, the statement will be canceled after only 1 second. If you call setQueryTimeout on a PreparedStatement, and execute the same statement several times, the timeout only takes affect on the first statement.

If you call setQueryTimeout on one Statement, but don't execute it, the timer will still fire, possible on an unrelated victim Statement. The root cause of all of these bugs was that the timer was started at the setQueryTimeout call, not on the execute call. Also, remove the finally-block from the cancellation task's run-method, because that might erroneously cancel the timer for the next query, if a new query is started using the same statement fast enough. Author: Heikki Linnakangas. Allow testing to continue when local host name doesn't resolve It seems to be a common and default configuration on some Linux systems for the local hostname not to resolve to the loopback IP address.

This causes testTimeoutOccurs(org.postgresql.test.jdbc2.LoginTimeoutTest) to fail. I'm seeing this on Fedora 17 among others.

While it's best to fix such systems, not causing an easily avoided and spurious failure in PgJDBC's test suite is probably worthwhile. Spit out a warning and continue.

A BitSet is a compact representation if we're only considering builtin types that will have low oids, but if any user defined types are enabled, all bets are off. Once the oid counter exceeds INTMAX, database connections were failing outright even if no high oid types used binary transfer because we represent these oids with negative values that a BitSet cannot handle.

Move logic out of concrete JDBC version classes. The concrete JDBC implementation classes should do as little work as possible. They exist solely to connect the right set of concrete implemention classes, leaving all the real work to the Abstract versions.

Some logic had started to creep out into these concrete classes which is bad because it duplicates code in paths that aren't likely to be tested by a developer who is working primarily with a single JDK version.

This solves a major performance problem for ResultSetMetaData users which did not cache the ResultSetMetaData object.

One of the users is the driver's own implementation of updatable ResultSets, so this can't be worked around solely in end user code. In the 9.0 and earlier releases, the Field objects were used to hold database lookup results and these were longer lived than the ResultSetMetaData object. Now that ResultSetMetaData is holding these database lookups we must hold onto the object to avoid repeating the database queries.

Reported as bug #6293, fix by Steven Schlansker. Author: Kris Jurka Date: Mon Feb 6 13: -0800. Consider searchpath when resolving type names to OIDs In case when types with the same name existed in several schemas, TypeInfoCache did not consider the current searchpath and was choosing an OID of a type not deterministically. These change will make the type from the current schema to be chosen. Also this change remains backwards compatible with the previous implementation, still being anble to find a type, that is not included into the current searchpath. Provided test fails now, as it does not TypeInfoCache directly.

So more work is to be done to make this test work. Author: Kris Jurka Date: Tue Mar 26 05: -0700.

Expose enhanced error message fields from constraint violations. The server now provides the schema, table, column, datatype, and constraint names for certain errors. So expose that to users so they don't have to go rummaging through the error text trying to find it.

The server doesn't always provide all the fields and doesn't cover all the error messages, but it's a good start. In the future it would be good to expose this information in a PGXXX class instead of the supposedly private ServerErrorMessage.

SSL client certificate via Keystore from a Resource file provided by Brendan Jurd It seems that the most common way to deal with this situation is to specify the keystore file and the password via system properties (javax.net.ssl.keyStore et. Al.), but that wasn't suitable in my case. I needed to be able to load the keystore from a Resource file embedded in the compiled JAR. The class I came up with is attached. It builds on the WrappedFactory provided in jdbc-postgres.

All the implementer needs to do is override the two abstract methods to provide an InputStream of the key store, and the password to access it. The InputStream could be a FileInputStream, or an InputStream returned by getResource, or whatever. This class uses the same keystore for KeyManager (selecting the key/cert to send as the client) and for TrustManager (verifying the server's certificate against trusted CAs). It could easily be extended to allow for two separate keystores by adding another couple of methods. Author: Steven Schlansker Date: Sun Dec 30 11: -0800.

Committed by jurka. Fetch all metadata for the ResultSet in one query instead of making a trip for each attribute of each column. Committed by jurka. Bring getSchemas up to JDBC 4 compliance. Return the additional TABLECATALOG column that was added in JDBC 3.

Additionally support the getSchemas method added in JDBC 4 which filters the returned schemas. Committed by jurka. Bring getProcedures/getProcedureColumns up to JDBC 4 compliance. Both methods have added a SPECIFICNAME column that can be used to differentiate between overloaded functions. GetProcedureColumns has added some other additional columns to describe the datatype being returned. Committed by jurka. Thanks to Thor Michael Store.

Allow the driver to support setObject with Types.DISTINCT. We report metadata indicating that values are of this type, so we'd better accept it coming back in.

Committed by jurka. Thanks to Vitalii Tymchyshyn. Support building with the 1.7 JDK. Committed by jurka. Support returning generated keys from batch statement execution.

Unfortunately we need to disable the actual batching that the driver does behind the scenes because now that it is returning potentially large result values we must avoid a deadlock. Committed by jurka. Report permission metadata for a table with no permissions correctly.

Committed by jurka. Thanks to danap.

Jdbc

Ensure that an XAConnection throws SQLExceptions appropriately even though it's a proxy class. Before this change it was throwing an InvocationTargetException instead of the actual cause. Committed by jurka. Thanks to Yaocl. Make updatable ResultSets work with SQLXML data. Committed by jurka.

Thanks to Michael Musset. If a domain has a not null constraint, report that information in the metadata for both DatabaseMetaData.getColumns and ResultSetMetaData.isNullable. Committed by jurka.

Thanks to Thomas Kellerer. In DatabaseMetaData.getSchemas, return the user's own temp schemas, but no others. Previously it wasn't returning the users own temp schema, but was showing all toast temp schemas.

Change ResultSetMetaData to return information on serial datatypes in getColumnTypeName to match up with the behaviour of DatabaseMetaData.getColumns. Committed by jurka. Fix literals that are injected into a SQL query to contain the PG specific E' marker if they are using the non-standard-conforming-strings backslash escaping. This will get rid of the warnings from escape stringwarning. Committed by jurka. Clear the generated keys associated with a Statement at the next execution. If the next execution doesn't want generated keys, we don't want to leave the old keys around.

Committed by jurka. The 9.1 server canonicalizes the clientencoding setting, so if we ask for unicode we get utf8. This confused the driver because previous versions just echo back what we asked for. Ask for the canonical name now. Committed by jurka. Thanks to Mike Fowler. When running tests, don't assume that we know the server's default transaction isolation level.

Committed by jurka. Thanks to Kevin Grittner. Update default permissions to account for changes in different server versions. 8.2 removed the rule permission while 8.4 added a trunctate permission.

Committed by jurka. Newer server versions (9.0+) allow extra floatdigits to be set to 3 instead of the old limit of 2 to get the maximum precision of floating point values out of the server. Committed by jurka.

Update the date tests for changes in the 1.6 JVM. Older versions allowed five digit years and single digit days and months. The latest code only allows a strict yyyy-mm-dd.

This changed somewhere between 1.6.0 11 and 1.6.021. Committed by jurka. Thanks to Mike Fowler. Use slightly different SQL State error codes for the different types of connection setup failures to indicate which can be retried and which cannot.

Make ResultSetMetaData.getColumnType match the results of DatabaseMetaData.getColumns.DATATYPE for domain and composite types. Committed by jurka. Thanks to Thomas Kellerer. Fix DatabaseMetaData.getColumns for 7.2 servers.

This was accidentally broken in the previous release. Committed by jurka. Fix a minor concurrency issue during the setup for processing escape functions. Committed by jurka. Thanks to Pierre Queinnec.

Fix DatabaseMetaData routines that return index information for a change in the 9.0 server that no longer renames the pgattribute entries for the index, but only adjust the table's attributes on a column rename. Committed by jurka.

Thanks to Adam Rauch. Track the tail of the SQLWarning chain so we can quickly add a new element to it instead of having to walk the entire chain from the head. This is important for the performance of handling plpgsql functions which do a ton of RAISE NOTICES which get translated into warnings. Committed by jurka. Thanks to Altaf Malik.

Change the processing of Statement.executeUpdate to complain if any of the results of a multi-statement query string return a ResultSet. Previously we were only checking the first result which resulted in silent partial execution of later SELECT statements. Committed by jurka.

Thanks to Joseph Shraibman. Check that a Connection hasn't been closed before allowing any operations on it. Committed by jurka. Thanks to Kevin Grittner. Don't allow rollback or commit when a Connection is in autocommit mode. Committed by jurka.

Thanks to Kevin Grittner. Change the SQLStates reported for using a closed Connection and closed ResultSet to be more consistent. Report connection doesnot exist (08003) for a closed Connection and objectnot instate (55000) for a ResultSet. Committed by jurka. When a COPY operation is the first statement issued in a transaction, it was not sending the BEGIN necessary to start the transaction. Committed by jurka.

Thanks to Maciek Sakrejda. The 8.4 release added some code to avoid re-describing a statement if we already had the type information available by copying the resolved type information from the query to the parameters. Its goal was just to overwrite parameters without a type (unknown), but it was actually overwriting all types which could change the query's desired behaviour. Committed by jurka. Thanks to Hiroshi Saito.

Fix the ORDINAL POSITION in the DatabaseMetaData.getColumns. Previously we were returning simply pgattribute.attnum, but that doesn't work in the presence of dropped columns because later columns don't get their attnum decremented if a preceding column is dropped. Instead use the rownumber window function for 8.4 and later servers to figure out the live column position. Committed by jurka. Always specify an XA error code when creating an XAException. Otherwise a transaction manager won't know what to do with the error and may have to assume the worst.

Committed by jurka. Thanks to Heikki Linnakangas, Justin Bertram. LOB truncation didn't allow truncating to zero length because it was improperly using the positioning length checks which don't allow a zero length. Committed by jurka. Thanks to Simon Kissane.

Protocol sync was lost when a batch statement parameter had an embedded null byte. Committed by jurka.

Thanks to Pierre Queinnec. Fix a problem using the Copy API to copy data to the server from a Reader.

After reading data out of the Reader and into a buffer, we were sending the entire buffer on to the server, not just the subset of it that was filled by the read operation. Committed by jurka. Thanks to Leonardo F.

A XA transaction should not change the autocommit setting of a Connection. Ensure that we restore this property correctly after the XA transaction completes. Committed by jurka. Thanks to Heikki Linnakangas, Achilleas Mantzios. PoolingDataSources were not picking up all of the properties that were set for them.

Notably it would not give you a SSL connection when asked. Committed by jurka. Thanks to Eric Jain. When setNull is called with a TIME or TIMESTAMP type we cannot pass that type information on to the backend because we really don't know whether it is with or without a time zone.

For a NULL value it doesn't matter, but we can't establish a type because a later call with a non-null value using the same PreparedStatement can potentially end up using a specific type that is incorrect.
