◆ ContinueOnError()

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.

Parameters
bool$modeexecute
Return values
boolcurrent continueOnError mode

Call this method to clean up after an adoSchema object that is no longer in use.

Deprecated
adoSchema now cleans up automatically.

◆ ExecuteInline()

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.

Parameters
bool$modeexecute
Return values
boolcurrent execution mode
See also
ParseSchema()
ExecuteSchema()

◆ executeInline()

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.

Parameters
bool$modeexecute
Return values
boolcurrent execution mode
See also
ParseSchema()
ExecuteSchema()

◆ ExecuteSchema()

adoSchema::ExecuteSchema ( $sqlArray = NULL,
$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.

See also
ParseSchema()
ParseSchemaString()
ExecuteInline()
Parameters
array$sqlArrayArray of SQL statements that will be applied rather than the current schema.
boolean$continueOnErrContinue to apply the schema even if an error occurs.
Returns
integer 0 if failure, 1 if errors, 2 if successful.

◆ executeSchema()

adoSchema::executeSchema ( $sqlArray = NULL,
$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.

See also
parseSchema()
parseSchemaString()
executeInline()
Parameters
array$sqlArrayArray of SQL statements that will be applied rather than the current schema.
boolean$continueOnErrContinue to apply the schema even if an error occurs.
Returns
integer 0 if failure, 1 if errors, 2 if successful.

◆ existingData()

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.

Parameters
int$modeXMLS_MODE_INSERT, XMLS_MODE_UPDATE, or XMLS_MODE_IGNORE
Return values
intcurrent mode

◆ ExtractSchema()

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.

Parameters
boolean$dataInclude data in schema dump
Return values
stringGenerated XML schema

◆ extractSchema()

adoSchema::extractSchema ( $data = FALSE,
$indent = '  ',
$prefix = '',
$stripprefix = 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 tables in the schema.

Parameters
boolean$datainclude data in schema dump
string$indentindentation to use
string$prefixextract only tables with given prefix
boolean$stripprefixstrip prefix string when storing in XML schema
Return values
stringGenerated XML schema

◆ ParseSchema()

adoSchema::ParseSchema ( $filename,
$returnSchema = FALSE )

Loads an XML schema from a file and converts it to SQL.

See also
ParseSchemaString()
Parameters
string$fileName of XML schema file.
bool$returnSchemaReturn schema rather than parsing.
Return values
arrayArray of SQL queries, ready to execute

◆ parseSchema()

adoSchema::parseSchema ( $filename,
$returnSchema = FALSE )

Loads an XML schema from a file and converts it to 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 create the database described. This method automatically converts the schema to the latest axmls schema version.

See also
ParseSchemaString()
Parameters
string$fileName of XML schema file.
bool$returnSchemaReturn schema rather than parsing.
Return values
arrayArray of SQL queries, ready to execute

◆ ParseSchemaFile()

adoSchema::ParseSchemaFile ( $filename,
$returnSchema = FALSE )

Loads an XML schema from a file and converts it to SQL.

Call this method to load the specified schema from a file (see the DTD for the proper format) and generate the SQL necessary to create the database described by the schema.

Parameters
string$fileName of XML schema file.
bool$returnSchemaReturn schema rather than parsing.
Return values
arrayArray of SQL queries, ready to execute.
Deprecated
Replaced by adoSchema\ParseSchema() and adoSchema\ParseSchemaString()
See also
ParseSchema()
ParseSchemaString()

◆ parseSchemaFile()

adoSchema::parseSchemaFile ( $filename,
$returnSchema = FALSE )

Loads an XML schema from a file and converts it to SQL.

Call this method to load the specified schema directly from a file (see the DTD for the proper format) and generate the SQL necessary to create the database described by the schema. Use this method when you are dealing with large schema files. Otherwise, parseSchema() is faster. This method does not automatically convert the schema to the latest axmls schema version. You must convert the schema manually using either the convertSchemaFile() or convertSchemaString() method.
