[ Top ]

string quoteIdentifier(
string
$str)

Quote a string so it can be safely used as a table or column name

Delimiting style depends on which database driver is being used.

NOTE: just because you CAN use delimited identifiers doesn't mean you SHOULD use them. In general, they end up causing way more problems than they solve.

Portability is broken by using the following characters inside delimited identifiers:

backtick (`) -- due to MySQL
double quote (") -- due to Oracle
brackets ([ or ]) -- due to Access

Delimited identifiers are known to generally work correctly under the following drivers:

mssql
mysql
mysqli
oci8
odbc(access)
odbc(db2)
pgsql
sqlite
sybase

InterBase doesn't seem to be able to use delimited identifiers via PHP 4. They work fine under PHP 5.

Return: quoted identifier string
Access: public

Overridden in child classes as:

MDB2_Driver_mysql::quoteIdentifier(): Quote a string so it can be safely used as a table or column name

MDB2_Driver_mssql::quoteIdentifier(): Quote a string so it can be safely used as a table / column name

Parameters:

string $str — identifier name to be quoted

object a &raiseError(
[mixed
$code = null], [int
$mode = null], [mixed
$options = null], [string
$userinfo = null])

This method is used to communicate an error and invoke error callbacks etc. Basically a wrapper for PEAR::raiseError without the message string.

Return: PEAR error object
See: PEAR_Error

Parameters:

mixed	`$code`	—	integer error code, or a PEAR error object (all other parameters are ignored if this parameter is an object
int	`$mode`	—	error mode, see PEAR_Error docs
mixed	`$options`	—	If error mode is PEAR_ERROR_TRIGGER, this is the error level (E_USER_NOTICE etc). If error mode is PEAR_ERROR_CALLBACK, this is the callback function, either as a function name, or as an array of an object and method name. For other error modes this parameter is ignored.
string	`$userinfo`	—	Extra debug information. Defaults to the last query and native error code.

mixed replace(
string
$table, array
$fields)

Execute a SQL REPLACE query. A REPLACE query is identical to a INSERT query, except that if there is already a row in the table with the same key field values, the REPLACE query just updates its values instead of inserting a new row.

The REPLACE type of query does not make part of the SQL standards. Since pratically only MySQL implements it natively, this type of query is emulated through this method for other DBMS using standard types of queries inside a transaction to assure the atomicity of the operation.

Return: MDB2_OK on success, a MDB2 error on failure
Access: public

Overridden in child classes as:

MDB2_Driver_mysql::replace(): Execute a SQL REPLACE query. A REPLACE query is identical to a INSERT query, except that if there is already a row in the table with the same key field values, the REPLACE query just updates its values instead of inserting a new row.

MDB2_Driver_sqlite::replace(): Execute a SQL REPLACE query. A REPLACE query is identical to a INSERT query, except that if there is already a row in the table with the same key field values, the REPLACE query just updates its values instead of inserting a new row.

MDB2_xxx::replace(): Execute a SQL REPLACE query. A REPLACE query is identical to a INSERT query, except that if there is already a row in the table with the same key field values, the REPLACE query just updates its values instead of inserting a new row.

Parameters:

string $table — name of the table on which the REPLACE query will be executed.

array

$fields

—

associative array that describes the fields and the values that will be inserted or updated in the specified table. The indexes of the array are the names of all the fields of the table. The values of the array are also associative arrays that describe the values and other properties of the table fields.

Here follows a list of field properties that need to be specified:

value Value to be assigned to the specified field. This value may be of specified in database independent type format as this function can perform the necessary datatype conversions.

Default: this property is required unless the Null property is set to 1.

type Name of the type of the field. Currently, all types Metabase are supported except for clob and blob.

Default: no type conversion

null Boolean property that indicates that the value for this field should be set to null.

The default value for fields missing in INSERT queries may be specified the definition of a table. Often, the default value is already null, but since the REPLACE may be emulated using an UPDATE query, make sure that all fields of the table are listed in this function argument array.

Default: 0

key Boolean property that indicates that this field should be handled as a primary key or at least as part of the compound unique index of the table that will determine the row that will updated if it exists or inserted a new row otherwise.

This function will fail if no key field is specified or if the value of a key field is set to null because fields that are part of unique index they may not be null.

Default: 0
