adoSchema::ContinueOnError | ( | $mode = NULL | ) |
Enables/disables SQL continue on error.
Call this method to enable or disable continuation of SQL execution if an error occurs. If the mode is set to TRUE (continue), AXMLS will continue to apply SQL to the database, even if an error occurs. If the mode is set to FALSE (halt), AXMLS will halt execution of generated sql if an error occurs, though parsing of the schema will continue.
bool | $mode | execute |

If the mode is set to TRUE (continue), AXMLS will continue to apply SQL to the database, even if an error occurs.

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 For instance, to convert a schema created for an pre-1.0 version for AXMLS (DTD version 0.1) to a newer version of the DTD (e.g. 0.2).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.
string | $filename | Name of XML schema file that will be converted. |
string | $newVersion | DTD version to convert to. |
string | $newFile | File name of (converted) output file. |
string | Converted XML schema or FALSE if an error occurs. |

For instance, to convert a schema created for an pre-1.0 version for AXMLS (DTD version 0.1) to a newer version of the DTD (e.g. 0.2).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.

For instance, to convert a schema created for an pre-1.0 version for AXMLS (DTD version 0.1) to a newer version of the DTD (e.g. 0.2).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.

Call this method to clean up after an adoSchema object that is no longer in use.
adoSchema::ExecuteInline | ( | $mode = NULL | ) |
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.
bool | $mode | execute |
bool | current execution mode |
adoSchema::executeInline | ( | $mode = NULL | ) |
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.
bool | $mode | execute |
bool | current execution mode |
adoSchema::ExecuteSchema | ( | $sqlArray = NULL, | |
$continueOnErr = NULL ) |

boolean | $continueOnErr | Continue to apply the schema even if an error occurs. |

$continueOnErr = NULL ) |
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.
array | $sqlArray | Array of SQL statements that will be applied rather than the current schema. |
boolean | $continueOnErr | Continue to apply the schema even if an error occurs. |
adoSchema::existingData | ( | $mode = NULL | ) |
Specifies how to handle existing data row when there is a unique key conflict.
The existingData setting specifies how the parser should handle existing rows when a unique key violation occurs during the insert. This can happen when inserting data into an existing table with one or more primary keys or unique indexes. The existingData method takes one of three options: XMLS_MODE_INSERT attempts to always insert the data as a new row. In the event of a unique key violation, the database will generate an error. XMLS_MODE_UPDATE attempts to update the any existing rows with the new data based upon primary or unique key fields in the schema. If the data row in the schema specifies no unique fields, the row data will be inserted as a new row. XMLS_MODE_IGNORE specifies that any data rows that would result in a unique key violation be ignored; no inserts or updates will take place. For backward compatibility, the default setting is XMLS_MODE_INSERT, but XMLS_MODE_UPDATE will generally be the most appropriate setting.
int | $mode | XMLS_MODE_INSERT, XMLS_MODE_UPDATE, or XMLS_MODE_IGNORE |
int | current mode |
adoSchema::ExtractSchema | ( | $data = FALSE | ) |
Extracts an XML schema from an existing database.
Call this method to create an XML schema string from an existing database. If the data parameter is set to TRUE, AXMLS will include the data from the database in the schema.
boolean | $data | Include data in schema dump |
string | Generated XML schema |
adoSchema::extractSchema | ( | $data = FALSE, | |
$indent = ' ', | |||
$prefix = '', | |||
$stripprefix = false ) |
