that can be used to build a database, and to build the database using the SQL array.
| __construct( $db ) X-Ref |
| Creates an adoSchema object Creating an adoSchema object is the first step in processing an XML schema. The only parameter is an ADOdb database connection object, which must already have been created. param: object $db ADOdb database connection object. |
| SetUpgradeMethod( $method = '' ) X-Ref |
| Sets the method to be used for upgrading an existing database Use this method to specify how existing database objects should be upgraded. The method option can be set to ALTER, REPLACE, BEST, or NONE. ALTER attempts to alter each database object directly, REPLACE attempts to rebuild each object from scratch, BEST attempts to determine the best upgrade method for each object, and NONE disables upgrading. This method is not yet used by AXMLS, but exists for backward compatibility. The ALTER method is automatically assumed when the adoSchema object is instantiated; other upgrade methods are not currently supported. returns: string Upgrade method used param: string $method Upgrade method (ALTER|REPLACE|BEST|NONE) |
| ExecuteInline( $mode = NULL ) X-Ref |
| Enables/disables inline SQL execution. Call this method to enable or disable inline execution of the schema. If the mode is set to TRUE (inline execution), AXMLS applies the SQL to the database immediately as each schema entity is parsed. If the mode is set to FALSE (post execution), AXMLS parses the entire schema and you will need to call adoSchema::ExecuteSchema() to apply the schema to the database. param: bool $mode execute return: bool current execution mode |
| ContinueOnError( $mode = NULL ) X-Ref |
| Enables/disables SQL continue on error. Call this method to enable or disable continuation of SQL execution if an error occurs.

| ParseSchemaString( $xmlstring, $returnSchema = FALSE ) X-Ref |

| RemoveSchema( $filename, $returnSchema = FALSE ) X-Ref |
| Loads an XML schema from a file and converts it to uninstallation SQL. Call this method to load the specified schema (see the DTD for the proper format) from the filesystem and generate the SQL necessary to remove the database described. param: string $file Name of XML schema file. param: bool $returnSchema Return schema rather than parsing. return: array Array of SQL queries, ready to execute |
| RemoveSchemaString( $schema, $returnSchema = FALSE ) X-Ref |
| Converts an XML schema string to uninstallation SQL. Call this method to parse a string containing an XML schema (see the DTD for the proper format) and generate the SQL necessary to uninstall the database described by the schema. param: string $schema XML schema string. param: bool $returnSchema Return schema rather than parsing. return: array Array of SQL queries, ready to execute. |
| ExecuteSchema( $sqlArray = NULL, $continueOnErr = NULL ) X-Ref |
| Applies the current XML schema to the database (post execution). Call this method to apply the current schema (generally created by calling ParseSchema() or ParseSchemaString() ) to the database (creating the tables, indexes, and executing other SQL specified in the schema) after parsing. returns: integer 0 if failure, 1 if errors, 2 if successful. param: array $sqlArray Array of SQL statements that will be applied rather than param: boolean $continueOnErr Continue to apply the schema even if an error occurs. |
| PrintSQL( $format = 'NONE' ) X-Ref |
| Returns the current SQL array. Call this method to fetch the array of SQL queries resulting from ParseSchema() or ParseSchemaString(). param: string $format Format: HTML, TEXT, or NONE (PHP array) return: array Array of SQL statements or FALSE if an error occurs |
| SaveSQL( $filename = './schema.sql' ) X-Ref |
| Saves the current SQL array to the local filesystem as a list of SQL queries. Call this method to save the array of SQL queries (generally resulting from a parsed XML schema) to the filesystem. param: string $filename Path and name where the file should be saved. return: boolean TRUE if save is successful, else FALSE. |

| XML Callback to process CDATA elements |
| _tag_close( &$parser, $tag ) X-Ref |
| XML Callback to process end elements |
| ConvertSchemaString( $schema, $newVersion = NULL, $newFile = NULL ) X-Ref |
| Converts an XML schema string to the specified DTD version. Call this method to convert a string containing an XML schema to a different AXMLS DTD version. For instance, to convert a schema created for an pre-1.0 version for AXMLS (DTD version 0.1) to a newer version of the DTD (e.g. 0.2). If no DTD version parameter is specified, the schema will be converted to the current DTD version. If the newFile parameter is provided, the converted schema will be written to the specified file. param: string $schema String containing XML schema that will be converted. param: string $newVersion DTD version to convert to. param: string $newFile File name of (converted) output file. return: string Converted XML schema or FALSE if an error occurs. |

| Converts an XML schema file to the specified DTD version. Call this method to convert the specified XML schema file to a different AXMLS DTD version. For instance, to convert a schema created for an pre-1.0 version for AXMLS (DTD version 0.1) to a newer version of the DTD (e.g. 0.2). If no DTD version parameter is specified, the schema will be converted to the current DTD version. If the newFile parameter is provided, the converted schema will be written to the specified file. param: string $filename Name of XML schema file that will be converted. param: string $newVersion DTD version to convert to. param: string $newFile File name of (converted) output file. return: string Converted XML schema or FALSE if an error occurs. |
