Methods summary
`protected`	# `_connect( )` Creates a connection resource. Creates a connection resource.
`public boolean`	# `isConnected( )` Test if a connection is active Test if a connection is active Returns `boolean`
`public`	# `closeConnection( )` Force the connection to close. Force the connection to close.
`public Zend_Db_Statement_Db2`	# `prepare( string $sql )` Returns an SQL statement for preparation. Returns an SQL statement for preparation. Parameters `$sql` `string` The SQL statement with placeholders. Returns `Zend_Db_Statement_Db2`
`public integer`	# `_getExecuteMode( )` Gets the execution mode Gets the execution mode Returns `integer` the execution mode (DB2_AUTOCOMMIT_ON or DB2_AUTOCOMMIT_OFF)
`public`	# `_setExecuteMode( integer $mode )` Parameters `$mode` `integer`
`protected string`	# `_quote( string $value )` Quote a raw string. Quote a raw string. Parameters `$value` `string` Raw string Returns `string` Quoted string
`public string`	# `getQuoteIdentifierSymbol( )` Returns `string`
`public array`	# `listTables( string $schema = null )` Returns a list of the tables in the database. Returns a list of the tables in the database. Parameters `$schema` `string` OPTIONAL Returns `array`
`public array`	# `describeTable( string $tableName, string $schemaName = null )` Returns the column descriptions for a table. Returns the column descriptions for a table. The return value is an associative array keyed by the column name, as returned by the RDBMS. The value of each array element is an associative array with the following keys: SCHEMA_NAME => string; name of database or schema TABLE_NAME => string; COLUMN_NAME => string; column name COLUMN_POSITION => number; ordinal position of column in table DATA_TYPE => string; SQL datatype name of column DEFAULT => string; default expression of column, null if none NULLABLE => boolean; true if column can have nulls LENGTH => number; length of CHAR/VARCHAR SCALE => number; scale of NUMERIC/DECIMAL PRECISION => number; precision of NUMERIC/DECIMAL UNSIGNED => boolean; unsigned property of an integer type DB2 not supports UNSIGNED integer. PRIMARY => boolean; true if column is part of the primary key PRIMARY_POSITION => integer; position of column in primary key IDENTITY => integer; true if column is auto-generated with unique values Parameters `$tableName` `string` `$schemaName` `string` OPTIONAL Returns `array`
`public string`	# `lastSequenceId( string $sequenceName )` Return the most recent value from the specified sequence in the database. This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null. Return the most recent value from the specified sequence in the database. This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null. Parameters `$sequenceName` `string` Returns `string`
`public string`	# `nextSequenceId( string $sequenceName )` Generate a new value from the specified sequence in the database, and return it. This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null. Generate a new value from the specified sequence in the database, and return it. This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null. Parameters `$sequenceName` `string` Returns `string`
`public string`	# `lastInsertId( string $tableName = null, string $primaryKey = null, string $idType = null )` Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column. Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column. As a convention, on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2), this method forms the name of a sequence from the arguments and returns the last id generated by that sequence. On RDBMS brands that support IDENTITY/AUTOINCREMENT columns, this method returns the last value generated for such a column, and the table name argument is disregarded. The IDENTITY_VAL_LOCAL() function gives the last generated identity value in the current process, even if it was for a GENERATED column. Parameters `$tableName` `string` OPTIONAL `$primaryKey` `string` OPTIONAL `$idType` `string` OPTIONAL used for i5 platform to define sequence/idenity unique value Returns `string`
`protected`	# `_beginTransaction( )` Begin a transaction. Begin a transaction.
`protected`	# `_commit( )` Commit a transaction. Commit a transaction.
`protected`	# `_rollBack( )` Rollback a transaction. Rollback a transaction.
`public`	# `setFetchMode( integer $mode )` Set the fetch mode. Set the fetch mode. Parameters `$mode` `integer` Throws `Zend_Db_Adapter_Db2_Exception`
`public string`	# `limit( string $sql, integer $count, integer $offset = 0 )` Adds an adapter-specific LIMIT clause to the SELECT statement. Adds an adapter-specific LIMIT clause to the SELECT statement. Parameters `$sql` `string` `$count` `integer` `$offset` `integer` OPTIONAL Returns `string`
`public boolean`	# `supportsParameters( string $type )` Check if the adapter supports real SQL parameters. Check if the adapter supports real SQL parameters. Parameters `$type` `string` 'positional' or 'named' Returns `boolean`
`public string`	# `getServerVersion( )` Retrieve server version in PHP style Retrieve server version in PHP style Returns `string`
`public boolean`	# `isI5( )` Return whether or not this is running on i5 Return whether or not this is running on i5 Returns `boolean`
`protected`	# `_determineI5( )` Check the connection parameters according to verify type of used OS Check the connection parameters according to verify type of used OS
`protected array`	# `_i5listTables( $schema = null )` Db2 On I5 specific method Db2 On I5 specific method Returns a list of the tables in the database . Used only for DB2/400. Returns `array`
`protected`	# `_i5LastInsertId( $objectName = null, $idType = null )`
