Try to make a database connection to the given URL. The driver should return "null" if it - * realizes it is the wrong kind of driver to connect to the given URL. This will be common, as - * when the JDBC driverManager is asked to connect to a given URL, it passes the URL to each - * loaded driver in turn.

- * - *

The driver should raise an SQLException if it is the right driver to connect to the given URL, - * but has trouble connecting to the database.

- * - *

The java.util.Properties argument can be used to pass arbitrary string tag/value pairs as - * connection arguments.

- * - *
    - *
  • user - (required) The user to connect as
    • - *
  • password - (optional) The password for the user
    • - *
  • ssl -(optional) Use SSL when connecting to the server
    • - *
  • readOnly - (optional) Set connection to read-only by default
    • - *
  • charSet - (optional) The character set to be used for converting to/from - * the database to unicode. If multibyte is enabled on the server then the character set of the - * database is used as the default, otherwise the jvm character encoding is used as the default. - * This value is only used when connecting to a 7.2 or older server.
    • - *
  • loglevel - (optional) Enable logging of messages from the driver. The value is an integer - * from 0 to 2 where: OFF = 0, INFO =1, DEBUG = 2 The output is sent to - * DriverManager.getPrintWriter() if set, otherwise it is sent to System.out.
    • - *
  • compatible - (optional) This is used to toggle between different functionality - * as it changes across different releases of the jdbc driver code. The values here are versions - * of the jdbc client and not server versions. For example in 7.1 get/setBytes worked on - * LargeObject values, in 7.2 these methods were changed to work on bytea values. This change in - * functionality could be disabled by setting the compatible level to be "7.1", in which case the - * driver will revert to the 7.1 functionality.
    • - *
- * - *

Normally, at least "user" and "password" properties should be included in the properties. For a - * list of supported character encoding , see - * http://java.sun.com/products/jdk/1.2/docs/guide/internat/encoding.doc.html Note that you will - * probably want to have set up the Postgres database itself to use the same encoding, with the - * {@code -E } argument to createdb.

Try to make a database connection to the given URL. The driver should return "null" if it + * realizes it is the wrong kind of driver to connect to the given URL. This will be common, as + * when the JDBC driverManager is asked to connect to a given URL, it passes the URL to each + * loaded driver in turn.

+ * + *

The driver should raise an SQLException if it is the right driver to connect to the given URL, + * but has trouble connecting to the database.

+ * + *

The java.util.Properties argument can be used to pass arbitrary string tag/value pairs as + * connection arguments.

+ * + *
    + *
  • user - (required) The user to connect as
    • + *
  • password - (optional) The password for the user
    • + *
  • ssl -(optional) Use SSL when connecting to the server
    • + *
  • readOnly - (optional) Set connection to read-only by default
    • + *
  • charSet - (optional) The character set to be used for converting to/from + * the database to unicode. If multibyte is enabled on the server then the character set of the + * database is used as the default, otherwise the jvm character encoding is used as the default. + * This value is only used when connecting to a 7.2 or older server.
    • + *
  • loglevel - (optional) Enable logging of messages from the driver. The value is an integer + * from 0 to 2 where: OFF = 0, INFO =1, DEBUG = 2 The output is sent to + * DriverManager.getPrintWriter() if set, otherwise it is sent to System.out.
    • + *
  • compatible - (optional) This is used to toggle between different functionality + * as it changes across different releases of the jdbc driver code. The values here are versions + * of the jdbc client and not server versions. For example in 7.1 get/setBytes worked on + * LargeObject values, in 7.2 these methods were changed to work on bytea values. This change in + * functionality could be disabled by setting the compatible level to be "7.1", in which case the + * driver will revert to the 7.1 functionality.
    • + *
+ * + *

Normally, at least "user" and "password" properties should be included in the properties. For a + * list of supported character encoding , see + * http://java.sun.com/products/jdk/1.2/docs/guide/internat/encoding.doc.html Note that you will + * probably want to have set up the Postgres database itself to use the same encoding, with the + * {@code -E } argument to createdb.

Escapes a given text value as a literal, wraps it in single quotes, casts it to the - * to the given data type, and finally wraps the whole thing in parentheses.

- * - *

For example, "123" and "int4" becomes "('123'::int)"

- * - *

The additional parentheses is added to ensure that the surrounding text of where the - * parameter value is entered does modify the interpretation of the value.

- * - *

For example if our input SQL is: SELECT ?b

- * - *

Using a parameter value of '{}' and type of json we'd get:

- * - * 
-   * test=# SELECT ('{}'::json)b;
-   *  b
-   * ----
-   *  {}
-   *
- * - *

But without the parentheses the result changes:

- * - * 
-   * test=# SELECT '{}'::jsonb;
-   * jsonb
