Methods summary
`public`	# `__construct( string $module )` Initialize resource helper instance Initialize resource helper instance Parameters `$module` `string` $module
`protected Varien_Db_Adapter_Interface`	# `_getReadAdapter( )` Retrieve connection for read data Retrieve connection for read data Returns `Varien_Db_Adapter_Interface`
`protected Varien_Db_Adapter_Interface`	# `_getWriteAdapter( )` Retrieve connection for write data Retrieve connection for write data Returns `Varien_Db_Adapter_Interface`
`protected Varien_Db_Adapter_Interface`	# `_getConnection( string $name )` Retrieves connection to the resource Retrieves connection to the resource Parameters `$name` `string` $name Returns `Varien_Db_Adapter_Interface`
`public string`	# `escapeLikeValue( string $value, array $options = array() )` Escapes value, that participates in LIKE, with '\' symbol. Note: this func cannot be used on its own, because different RDMBS may use different default escape symbols, so you should either use addLikeEscape() to produce LIKE construction, or add escape symbol on your own. Escapes value, that participates in LIKE, with '\' symbol. Note: this func cannot be used on its own, because different RDMBS may use different default escape symbols, so you should either use addLikeEscape() to produce LIKE construction, or add escape symbol on your own. By default escapes '_', '%' and '\' symbols. If some masking symbols must not be escaped, then you can set appropriate options in $options. $options can contain following flags: 'allow_symbol_mask' - the '_' symbol will not be escaped 'allow_string_mask' - the '%' symbol will not be escaped 'position' ('any', 'start', 'end') - expression will be formed so that $value will be found at position within string, by default when nothing set - string must be fully matched with $value Parameters `$value` `string` $value `$options` `array` $options Returns `string`
`abstract public Zend_Db_Expr`	# `addLikeEscape( string $value, array $options = array() )` Escapes, quotes and adds escape symbol to LIKE expression. For options and escaping see escapeLikeValue(). Escapes, quotes and adds escape symbol to LIKE expression. For options and escaping see escapeLikeValue(). Parameters `$value` `string` $value `$options` `array` $options Returns `Zend_Db_Expr` See `Mage_Core_Model_Resource_Helper_Abstract::escapeLikeValue()`
`public Zend_Db_Expr`	# `getCILike( string $field, string $value, array $options = array() )` Returns case insensitive LIKE construction. For options and escaping see escapeLikeValue(). Returns case insensitive LIKE construction. For options and escaping see escapeLikeValue(). Parameters `$field` `string` $field `$value` `string` $value `$options` `array` $options Returns `Zend_Db_Expr` See `Mage_Core_Model_Resource_Helper_Abstract::escapeLikeValue()`
`public array`	# `convertOldColumnDefinition( array $column )` Converts old pre-MMDB column definition for MySQL to new cross-db column DDL definition. Used to convert data from 3rd party extensions that hasn't been updated to MMDB style yet. Converts old pre-MMDB column definition for MySQL to new cross-db column DDL definition. Used to convert data from 3rd party extensions that hasn't been updated to MMDB style yet. E.g. Converts type 'varchar(255)' to array('type' => Varien_Db_Ddl_Table::TYPE_TEXT, 'length' => 255) Parameters `$column` `array` $column Returns `array`
