[DBAL-522] BC break : executeQuery with an array containing null value(s).

Tue, 21 May 2013 05:58:01 +0000

Hello, i have got an error with doctrine 2.3.4 when i try to run the following code :

 
    $conn->executeQuery(
        'INSERT INTO FOO (foo, bar) values (:foo, :bar)', 
         array('foo' => 1, 'bar' => null)
     );

Error : Value for :bar not found in params array. Params array key should be "bar"

This code worked with doctrine 2.3.3.

I think the error comes from the function 'extractParam' in SQLParserUtils.php (DBAL)

line 215 : if (isset($paramsOrTypes[$paramName]))

The key exists even if the value is null.
So it should be:

  if (array_key_exists($paramName, $paramsOrTypes))

I am not enough confident to try a PR.
Thanks in advance!

[DBAL-511] Schema\ColumnDiff incorrect with default varchar value and postgresql

Sat, 4 May 2013 11:15:53 +0000

I have a Schema\Table with a column:

$usersTable->addColumn("lastip", "string", array("length" => 32, "default" => ""));

When I use Schema\Comparator on this table I get a ColumnDiff:

object(Doctrine\DBAL\Schema\ColumnDiff)[554]
  public 'oldColumnName' => string 'lastip' (length=6)
  public 'column' => 
    object(Doctrine\DBAL\Schema\Column)[481]
      protected '_type' => 
        object(Doctrine\DBAL\Types\StringType)[278]
      protected '_length' => int 32
      protected '_precision' => int 10
      protected '_scale' => int 0
      protected '_unsigned' => boolean false
      protected '_fixed' => boolean false
      protected '_notnull' => boolean true
      protected '_default' => string '' (length=0)
      protected '_autoincrement' => boolean false
      protected '_platformOptions' => 
        array
          empty
      protected '_columnDefinition' => null
      protected '_comment' => null
      protected '_customSchemaOptions' => 
        array
          empty
      protected '_name' => string 'lastip' (length=6)
      protected '_namespace' => null
      protected '_quoted' => boolean false
  public 'changedProperties' => 
    array
      0 => string 'default' (length=7)
  public 'fromColumn' => 
    object(Doctrine\DBAL\Schema\Column)[293]
      protected '_type' => 
        object(Doctrine\DBAL\Types\StringType)[278]
      protected '_length' => int 32
      protected '_precision' => int 10
      protected '_scale' => int 0
      protected '_unsigned' => boolean false
      protected '_fixed' => boolean false
      protected '_notnull' => boolean true
      protected '_default' => string '''::character varying' (length=21)
      protected '_autoincrement' => boolean false
      protected '_platformOptions' => 
        array
          empty
      protected '_columnDefinition' => null
      protected '_comment' => string '' (length=0)
      protected '_customSchemaOptions' => 
        array
          empty
      protected '_name' => string 'lastip' (length=6)
      protected '_namespace' => null
      protected '_quoted' => boolean false

With "default" postgresql adds "::character varying" when it's a varchar.

This gives a alter sql query:

ALTER TABLE bolt_users ALTER lastip SET  DEFAULT ''

After executing this, the next time it's the ColumnDiff again. Should the "::character varying" part be ignored by doctrine? Because then the schema will be valid.

[DBAL-508] MySqlSchemaManager accessing undefined index tableColumn[comment]

Thu, 9 May 2013 16:08:45 +0000

in the method Doctrine\DBAL\Schema\MySqlSchemaManager::_getPortableTableColumnDefinition the index "comment" in the array $tableColumn is accessed without ensuring that this index is set. This leads to an Undefined index: comment warning in E_ALL-environments.

This method is triggered e.g. by the Doctrine\ORM\Tools\SchemaTool getUpdateSchemaSql method.

[DBAL-498] [GH-306] [DBAL-497] Fixed SQL Server platform replacing 'FROM' in column names during limit

Sat, 20 Apr 2013 07:58:03 +0000

This issue is created automatically through a Github pull request on behalf of shaneneuerburg:

Url: https://github.com/doctrine/dbal/pull/306

Message:

The regex used to replace the FROM clause was in a "starts with" form, which also matched column names that start with the word "FROM". This resulted in column names being replaced with the logic used for limiting, breaking the query once pagination is used. I added a whitespace requirement after "FROM' in the regex as well as a trailing whitespace in the replacement.

[DBAL-497] SQLServerPlatform modifies limit query incorrectly when column names start with "from"

Sat, 20 Apr 2013 07:57:51 +0000

I am working with a table that has columns that start with the word "from" (fromNumber, fromCity, etc). When SQLServerPlatform->doModifyLimitQuery is called, "from" in the names are incorrectly replaced. I suggest adding a whitespace requirement after FROM in the preg_replace on this line:
https://github.com/doctrine/dbal/blob/master/lib/Doctrine/DBAL/Platforms/SQLServerPlatform.php#L848

So this:

$query = preg_replace('/\sFROM/i', ", ROW_NUMBER() OVER ($over) AS doctrine_rownum FROM", $query);

Becomes this:

$query = preg_replace('/\sFROM\s/i', ", ROW_NUMBER() OVER ($over) AS doctrine_rownum FROM ", $query);

Message:

This PR improves listing table indexes in SQL Server. Currently table indexes are retrieved in the platform via a stored procedure <code>sp_helpindex</code> which causes problems with some SQL Server drivers like ODBC that cannot retrieve information from stored procedure calls. Table indexes are retrieved via native system tables now, which seems cleaner and is more flexible concerning which information to retrieve.
Additionally code duplication in <code>SQLServerSchemaManager::_getPortableTableIndexesList</code> is removed and simplified by this PR.

[DBAL-484] [GH-298] Fix SQL Server default constraints

This issue is created automatically through a Github pull request on behalf of deeky666:

Url: https://github.com/doctrine/dbal/pull/298

Message:

This PR fixes altering column default values. In SQL Server column default values are stored in constraints. <code>CREATE TABLE</code> statements with column declarations like <code>some_column NVARCHAR(50) NOT NULL DEFAULT 'default value'</code> internally creates a default constraint with an automatically generated name in the the system table `sys.default_constraints`. <code>ALTER TABLE</code> statements do not support the <code>DEFAULT</code> clause in column alteration declarations, leading in SQL syntax errors. Thus changing a column's default value is currently not possible.
To alter a column's default value, the old column's default constraint hast to be dropped and recreated again. As a default constraint has to be referenced by name to be dropped, we need to create each default constraint with an own unique name. This PR generates separate statements for default constraint declarations. It generates a unique name consisting of the table name and the column name the default constraint is created for.

This issue is created automatically through a Github pull request on behalf of deeky666:

Url: https://github.com/doctrine/dbal/pull/295

Message:

The functional <code>ModifyLimitQueryTest</code> makes false expectations about the query results. <code>LIMIT</code> queries without <code>ORDER BY</code> clause return non-deterministic results, therefore the test cannot make any expectations about which values are returned and in which order. You can only expect a certain number of results.
The test might still work on platforms like mysql when you assume results to be in an ascending order, because the database might put the results of a non-deterministic query in an ascending order by default. Still this is not reliable and not all vendors do that.
This PR changes the tests to have an ordered, deterministic results by default to have more reliable expectations. Also one test about a non-deterministic query was added, which just asserts the number of results returned.

The Connection::insert() method takes an array of types as its third argument:

But unfortunately, that's does not work. This commit add support for this, and of course, the old way still works.

[DBAL-444] OraclePlatform getSequenceNextValSQL not handling case/quoting properly on 11g

Thu, 4 Apr 2013 21:22:17 +0000

I have an installer script that uses ORM SchemaTool to create the entities in the DB and then populates with basic data using basic EM->persist calls via ORM.

Sequence objects are created, and when using the 10g Instant Client everything worked correctly, however, upon upgrade to latest version of the Instant Client Oracle seems to be expecting consistent case for these schema objects. It appears as if they are being created with a quoted name as they are created in lowercase. OraclePlatform::getSequenceNextValSQL, however, generates "SELECT entity_id_seq.nextval FROM DUAL" and this fails with error "General error: 2289 OCIStmtExecute: ORA-02289: sequence does not exist".

Executing "SELECT "entity_id_seq".nextval FROM DUAL" directly on the DB returns the correct value.

I believe this may also impact the code in http://www.doctrine-project.org/jira/browse/DBAL-278

[DBAL-442] Break the query building with multiple from parts

Mon, 22 Apr 2013 14:51:48 +0000

For example:

$queryBuilder
    ->select('DISTINCT c.id')
    ->from('Campaigns', 'c')
    ->leftJoin('c', 'CampaignOperations', 'od', 'od.campaignId = c.id AND od.operation = :operation')
    ->from('BannerGroups', 'bg')
    ->innerJoin('bg', 'BannerGroupStrategies', 'bgs', 'bgs.groupId = bg.id AND bgs.advSystem = :system')
    ->where('bg.campaignId = c.id');

Builded the query:

SELECT DISTINCT c.id FROM Campaigns s 
  LEFT JOIN CampaignOperations od ON (od.campaignId = c.id AND od.operation = :operation)
  INNER JOIN BannerGroupStrategies bgs ON (bgs.groupId = bg.id AND bgs.advSystem = :system), 
  BannerGroups bg
  WHERE (bg.campaignId = c.id)

If this query execute on mysql, we get error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'bg.id' in 'on clause'

Expected result:

SELECT DISTINCT c.id FROM Campaigns s 
  LEFT JOIN CampaignOperations od ON (od.campaignId = c.id AND od.operation = :operation),
  BannerGroups bg
  INNER JOIN BannerGroupStrategies bgs ON (bgs.groupId = bg.id AND bgs.advSystem = :system)
  WHERE (bg.campaignId = c.id)

Upsert support in DBAL (replace, insert into usw..)

[DBAL-162] BeforeInsertID & AfterInsertID emulation workflow, wie bei MDB2

Thu, 20 Sep 2012 06:19:57 +0000

The following workflow is necessary for portable code to work on all platforms:

$nextId = $conn->nextSequenceId();
$query = "INSERT INTO (id) VALUES (?)";
$conn->executeUpdate($query, array($nextId));
$nextId = $conn->lastInsertId();

[DBAL-131] Remove Static Types

Thu, 20 Sep 2012 06:19:57 +0000

the static types should be removed and made to instances of types that can differ between platforms.

Following reasons:

1. Some vendors already convert values to PHP types, for example integers. Not converting again could save about 15% wall-time for integers for example.
2. Some vendors require different type code, this is currently handled by expensive if checks.
3. If you want to change a type for one vendor but also use another vendor in the same request, then you have a problem currently.
4. If types were platform aware then we could make registering custom types simpler.

[DBAL-96] Make approach towards identifier quoting consistent

Duplicate — Thu, 20 Sep 2012 06:19:57 +0000

Make the use of `` a general approach for explicit quoting of identifiers
introduce AbstractPlatform::getRegularSQLIdentifierCase($identifier)
Introduce AbstractPlatform::isRegularIdentifier($identifier)
Fix Schema Assets not to lower-case, but to check for explicit quoting before.
Filter values of identifiers passed to all platform functions when they are used in information schema queries according to `` explicit quoting rules.

Problem: Schema is independent of a vendor, this means we have to pick a behavior, i propose SQL-92

http://savage.net.au/SQL/sql-92.bnf See <actual identifier>
http://www.alberton.info/dbms_identifiers_and_case_sensitivity.html

This means:

strtoupper() ALL tables, column, index, foreign key names that are not quoted by ``
For any Quoted identifiers by `` the case is kept.
We can introduce a validator to detect a schema that cannot be implemented with a given vendor platform.

In conjunction with the SQL reserved keywords tickets we can then improve the DatabaseDriver considerably to detect identifier casings

[DBAL-81] Add support for auto-commit = NO accross databases

Thu, 20 Sep 2012 06:19:57 +0000

Currently all databases are running in AUTO-COMMIT = Yes Mode. This means that you have to explicitly open a transaction to be able to use transactional features.

There should be support to run in auto-commit = no mode, which means after connect and after each commit a new transaction is opened automatically.

[DBAL-69] Varchar definition should automatically switch to CLOB for sizes larger than max varchar length.

Thu, 20 Sep 2012 06:19:57 +0000

In the future we would probably allow arbitrary large sizes here and switch to a CLOB definition automatically if the specifed string length is larger than max length.
